摘要

安全、高效施工是石油鉆井追求的目標(biāo)，工程技術(shù)人員迫切需要井下工礦診斷和鉆前預(yù)測(cè)的實(shí)用技術(shù)。在現(xiàn)有方法中最有發(fā)展前景的是隨鉆地震（SWD-Seismic While Drilling）和鉆柱振動(dòng)錄井。SWD以鉆頭為震源，在井場(chǎng)周?chē)贾玫卣鹩^測(cè)儀器收集井下鉆頭破巖產(chǎn)生的地震波，進(jìn)行鉆頭前方地層探測(cè)，實(shí)現(xiàn)鉆前預(yù)測(cè)。鉆柱振動(dòng)錄井利用鉆柱頂部測(cè)量的振動(dòng)信號(hào)，分析鉆進(jìn)過(guò)程中的鉆柱振動(dòng)特征，獲得井下鉆頭、所鉆地層和鉆柱的信息，進(jìn)行井下工礦實(shí)時(shí)監(jiān)測(cè)。

鉆柱是連接井底鉆頭與地面的信息通道，SWD利用鉆柱頂端振動(dòng)記錄估計(jì)鉆頭震源函數(shù)，與地面記錄道互相關(guān)建立地震剖面，獲得鉆頭前方地層反射界面和地層波速。鉆柱振動(dòng)錄井利用鉆柱頂端的振動(dòng)記錄提取鉆頭運(yùn)動(dòng)的頻譜特征、鉆柱運(yùn)動(dòng)與井壁的接觸情況、鉆頭與井底巖石的反射系數(shù)，進(jìn)行井下工礦診斷與實(shí)時(shí)監(jiān)測(cè)。鉆頭破巖振動(dòng)特征、鉆柱傳輸特性和振動(dòng)特征、鉆柱振動(dòng)信號(hào)分析方法成為發(fā)展SWD和鉆柱振動(dòng)錄井技術(shù)的關(guān)鍵。

本文在國(guó)內(nèi)外研究的基礎(chǔ)上，開(kāi)展了鉆頭破巖振動(dòng)室內(nèi)與礦場(chǎng)實(shí)驗(yàn)、鉆柱受迫振動(dòng)傳播方程建立與鉆頭振動(dòng)信號(hào)分析方法研究，初步掌握了鉆頭破巖振動(dòng)特征及影響因素，鉆柱振動(dòng)類型、傳播規(guī)律和影響因素，建立了傳遞矩陣和單邊反褶積自相關(guān)兩種鉆柱振動(dòng)信號(hào)分析方法，初步建立了鉆柱振動(dòng)分析方法的框架。

研究認(rèn)為鉆柱振動(dòng)是一受迫振動(dòng)問(wèn)題，需要將井底巖石-鉆頭-鉆柱-水龍頭作為一個(gè)“鉆柱振動(dòng)系統(tǒng)”來(lái)對(duì)待；鉆頭振動(dòng)頻譜包含了鉆頭工礦的信息，與鉆頭幾何結(jié)構(gòu)、地層特性和鉆進(jìn)參數(shù)密切相關(guān)，并具有較寬的頻帶；鉆柱具有軸向、旋轉(zhuǎn)和橫向振動(dòng)三種類型，鉆柱截面變化形成了鉆柱多次波，鉆柱結(jié)構(gòu)、頂?shù)走吔鐥l件對(duì)鉆柱波的傳播具有重要影響；建立了鉆柱振動(dòng)的傳遞矩陣計(jì)算模型，數(shù)值模擬與室內(nèi)管柱傳播模擬實(shí)驗(yàn)結(jié)果吻合較好；采用單邊反褶積自相關(guān)，獲得了鉆柱反射界面的多次波圖像和傳播速度。研究表明鉆頭振動(dòng)的頻譜、鉆柱振動(dòng)的頻譜與鉆柱反射界面成像、井底反射系數(shù)可作為鉆頭工礦、鉆柱工礦與地層特性的主要診斷參數(shù)，鉆柱多次波成像可獲得鉆柱波速度（時(shí)延），傳遞矩陣是鉆柱振動(dòng)分析的良好模型，可利用傳遞矩陣給出的鉆柱理論脈沖響應(yīng)（傳遞函數(shù)），反演井底反射系數(shù)，恢復(fù)鉆頭震源函數(shù)。

ABSTRACT

Drilling a well safely and efficiently is the aim of petroleum engineers, the drilling needs the downhole diagnosis and forecast techniques.The most promising existing methods are Seismic While Drilling(SWD)and Drill String Vibration Logging.SWD takes the working drill-bit as seismic source, acquires the drill bit seismic wave propagating through the formation by the geophone to predict formation property ahead of the drill-bit and reduce the drilling risk.The drill string vibration logging is a new technology to monitor the state of health of downhole tools, formation and drill string by analyzing the vibrations measured on the top of the drill string.It can be used to evaluate the formation drillability in real time.a On the basis of former research, we did the lab and well site experiments of drill bit vibration during breaking rock, built the propagation equation of drill string forced vibration and gave the drill string vibration analysis method;obtained some basic understanding of drill bit vibration property, drill string vibration modes and propagation characteristics;built up the drill string vibration analysis frame with the propagation matrix method and one-side deconvolved autocorrelation method.Our research demonstrate that the drill string vibration is forced vibration, it needs to consider the rock-drill bit-drill string-swivel as the “drill string vibration system”;the drill bit spectrum, with broad frequency band, is related to drill bit geometry ,formation property and drilling condition and gives the drill bit working condition information;drill string has axial, torsional and lateral vibration modes;changes of drill string cross-sections generates drill string multiples.There is a significant influence of drill string structure, top and bottom boundary condition to drill string wave propagation;We built up the drill string vibration propagation matrix, the numerical simulation match well with lab experiment results;obtained the drill string multiples image and wave velocity with one-side deconvolved autocorrelation method.Our research shows that the spectrums of drill bit and drill string vibration, drill string reflected interface imaging and downhole reflected coefficient can be used as the main diagnosis parameters of drill string and drill bit working condition and formation characteristics;drill string multiples imaging can be used to calculate the drill string wave velocity;propagation matrix method is a good method for drill string vibration analysis.We can get drill string theoretical impulse response and transfer function, the bottom reflection coefficient and the drill bit seismic source function on the basis of drill string vibration propagation matrix.

中文摘要

如何選擇合適的工程結(jié)構(gòu)抗震分析和設(shè)計(jì)方法一直是地震工程領(lǐng)域引人關(guān)注的重要問(wèn)題。隨著基于性態(tài)抗震設(shè)計(jì)思想的提出和發(fā)展，作為一種簡(jiǎn)化的實(shí)現(xiàn)性態(tài)設(shè)計(jì)分析的方法，Pushover方法引起了廣大學(xué)者和工程人員的興趣，并得到了廣泛的研究。本文針對(duì)以往Pushover方法的研究中存在的缺點(diǎn)和不足，對(duì)Pushover方法進(jìn)行了改進(jìn)，主要包括對(duì)模態(tài)Pushover方法的改進(jìn)、對(duì)鋼筋混凝土框架結(jié)構(gòu)Pushover位移反應(yīng)的修正、Pushover荷載模式與結(jié)構(gòu)性態(tài)指標(biāo)相關(guān)性的探討、基于模態(tài)Pushover分析方法確定結(jié)構(gòu)滯回耗能計(jì)算四個(gè)方面的問(wèn)題。本論文主要研究?jī)?nèi)容和成果包括以下幾個(gè)方面：

1.模態(tài)Pushover分析方法的一個(gè)重要假定是，結(jié)構(gòu)在強(qiáng)震作用下進(jìn)入非線性狀態(tài)時(shí)，作用于結(jié)構(gòu)的Pushover荷載模式保持不變；可是眾所周知，結(jié)構(gòu)發(fā)生屈服后，結(jié)構(gòu)的動(dòng)力特性會(huì)發(fā)生改變，結(jié)構(gòu)遭受的地震荷載也會(huì)發(fā)生變化，因此各階振型采用固定不變荷載模式的模態(tài)Pushover方法存在不足。本文提出將結(jié)構(gòu)的第一振型荷載模式改進(jìn)為兩階段加載模式，高階振型荷載模式保持固定不變，對(duì)結(jié)構(gòu)進(jìn)行改進(jìn)的模態(tài)Pushover分析。

2.建議了一種計(jì)算鋼筋混凝土框架結(jié)構(gòu)動(dòng)力彈塑性位移反應(yīng)的簡(jiǎn)便方法。通過(guò)對(duì)5個(gè)不同高度的鋼筋混凝土框架結(jié)構(gòu)在四類場(chǎng)地上80條地震動(dòng)作用下的動(dòng)力和靜力彈塑性位移反應(yīng)進(jìn)行統(tǒng)計(jì)分析，給出了結(jié)構(gòu)由靜力彈塑性方法得到的目標(biāo)位移估計(jì)動(dòng)力時(shí)程方法得到的目標(biāo)位移的修正公式。結(jié)果表明：場(chǎng)地條件對(duì)鋼筋混凝土框架結(jié)構(gòu)靜力彈塑性位移反應(yīng)和動(dòng)力時(shí)程位移反應(yīng)之間的關(guān)系影響顯著；對(duì)于II類和III類場(chǎng)地，可以直接采用結(jié)構(gòu)的靜力彈塑性方法計(jì)算結(jié)果替代動(dòng)力時(shí)程計(jì)算結(jié)果；對(duì)于I類場(chǎng)地和IV類場(chǎng)地，須采用修正公式對(duì)結(jié)構(gòu)的靜力彈塑性結(jié)果進(jìn)行修正。

3.通過(guò)對(duì)4個(gè)不同高度的鋼筋混凝土結(jié)構(gòu)，分別進(jìn)行了中等硬度場(chǎng)地上15條地震動(dòng)作用下的非線性動(dòng)力時(shí)程分析和不同荷載模式下的靜力彈塑性分析，求解了結(jié)構(gòu)的幾個(gè)重要反應(yīng)指標(biāo)，包括能力曲線、頂端位移角及層間位移角、以及塑性鉸分布，探討了不同荷載模式對(duì)鋼筋混凝土低層和高層結(jié)構(gòu)反應(yīng)指標(biāo)的影響程度，建議了適用于鋼筋混凝土低層和高層結(jié)構(gòu)的Pushover荷載模式。

4.提出基于模態(tài)Pushover分析的結(jié)構(gòu)滯回耗能計(jì)算方法。首先采用模態(tài)

Pushover分析計(jì)算結(jié)構(gòu)各階模態(tài)單自由度體系的特征參數(shù)，然后計(jì)算結(jié)構(gòu)各階模態(tài)單自由度體系對(duì)應(yīng)的滯回耗能，并將其進(jìn)行線性組合進(jìn)而確定結(jié)構(gòu)的滯回耗能，并與結(jié)構(gòu)通過(guò)動(dòng)力時(shí)程分析計(jì)算得到的滯回耗能進(jìn)行比較，從而給出一種物理概念簡(jiǎn)單、計(jì)算操作方便的確定結(jié)構(gòu)滯回耗能的方法。另外，為了便于計(jì)算結(jié)構(gòu)各階模態(tài)單自由度體系的滯回耗能，本文選取了國(guó)內(nèi)外四類場(chǎng)地土上總計(jì)320條強(qiáng)震記錄作為地震記錄數(shù)據(jù)庫(kù)，在統(tǒng)計(jì)分析的基礎(chǔ)上，給出了對(duì)應(yīng)于不同場(chǎng)地土和不同烈度區(qū)的單自由度體系等強(qiáng)度滯回耗能設(shè)計(jì)譜。

Improvements on Pushover Analysis Procedure

ABSTRACT

How to select the adequate procedure for seismic analysis and design of structures is an essential problem in earthquake engineering field.With the development of Performance-based Seismic Design, Pushover Analysis procedure has attracted many scientists’ and engineers’ attentions and been widely used for its conceptual simplicity and computational attractiveness.To overcome the limitation of Pushover Analysis procedure, some improvements on this procedure were performed in this paper, including the improvement on Modal Pushover Analysis, the revision of target displacement from the pushover analysis for reinforced concrete frame, the correlation of structural response parameters with different lateral load patterns, and the computation of the structural hysteretic energy based on Modal Pushover Analysis etc.The main contents of this dissertation are as follows.1.There is an important assumption that the pushover load patterns keep unchanged even after the structure yields in Modal Pushover Analysis procedure.Recognized the adoption of invariable lateral force distributions in the Modal Pushover Analysis procedure, an improved modal pushover analysis procedure is presented in this paper to estimate the seismic demands of structures, considering the redistribution of inertia forces.It is suggested that after establishing the idealized bilinear curve, a pushover analysis is once again conducted for the first mode in two phases: before and after the structure yields.For the two phases, the structural elastic natural mode and the floor displacement vector at the initial yielding point are used as the displacement shape vector, respectively.2.The approximately estimating method of displacement of reinforced concrete(RC)frame from static pushover analysis(POA)is developed with that from non-linear response history analysis(RHA).Based on the statistic analyses of the RHA and POA results for five RC frames with different height under 80 ground motions recorded at four site conditions, the revised formula of displacements from POA is presented from RHA.The results show that the site soil condition has an important effect on the relation between RHA and POA response results.And the POA results for I and IV site condition should be revised with the formula given in this study while the POA results for II and III site condition can be approximately considered as same to the RHA results.3.The RHA under 15 ground motions recorded on the medium site condition and POA with different lateral load patterns are performed for four RC structures with different height.Several important response quantities are obtained from the RHA and POA, including capacity curves, top displacement ratios and story drift ratios, and location of plastic hinges.The influence of different load patterns on the structural performance demands is discussed for the low-and the high-wise structures.And the rational load patterns for the low-and the high-wise structures are also suggested.4.A simple procedure is presented in this paper for estimating hysteretic energy demands of MDOF systems based on the modal pushover analysis(MPA).Firstly, the characteristic parameters of the modal SDOF systems of structures are computed, and the hysteretic energy is calculated for the modal SDOF systems, then the hysteretic energy demand of structures is obtained by combining these modal demands.In addition, with statistic results of nonlinear analysis of SDOF for 320 ground motions recorded at four site conditions, the equal-strength hysteretic energy design spectra are presented for different site condition and intensity regions.Key words: pushover analysis procedure, capacity spectrum method, the

內(nèi)容摘要

隨著INTERNET的迅速發(fā)展，人類正經(jīng)歷一場(chǎng)重大的技術(shù)變革，即電子商務(wù)的變革。電子商務(wù)源于電子數(shù)據(jù)交換，網(wǎng)絡(luò)技術(shù)的發(fā)展為電子商務(wù)注入了勃勃生機(jī)。由信息技術(shù)引發(fā)的電子商務(wù)雖然還處于發(fā)展階段，但它一經(jīng)進(jìn)入國(guó)際貿(mào)易領(lǐng)域，就對(duì)傳統(tǒng)的貿(mào)易方式產(chǎn)生了巨大的沖擊。傳統(tǒng)的貿(mào)易活動(dòng)每一筆交易涉及的主體一般包括買(mǎi)賣(mài)雙方、銀行、運(yùn)輸、海關(guān)、稅務(wù)、商檢等眾多部門(mén)，業(yè)務(wù)流程十分繁雜，效率低下，越來(lái)越不適應(yīng)當(dāng)今國(guó)際貿(mào)易業(yè)務(wù)快速發(fā)展的需要，電子商務(wù)則可以通過(guò)互聯(lián)網(wǎng)將交易各方連成一體，把其中部分或本文所提及的電子商務(wù)主要指國(guó)際電子商務(wù)，文章首先闡述了電子商務(wù)與國(guó)際貿(mào)易的關(guān)系，包括電子商務(wù)的經(jīng)濟(jì)特征及在國(guó)際貿(mào)易領(lǐng)域中的功能和優(yōu)勢(shì)。接下來(lái)是文章的主體部分——介紹電子商務(wù)對(duì)國(guó)際貿(mào)易的影響。分別從國(guó)際貿(mào)易理論和國(guó)際貿(mào)易現(xiàn)實(shí)兩方面予電子商務(wù)是一個(gè)龐大的命題，而本文力求闡述清楚的核心問(wèn)題是：在電子商務(wù)環(huán)境中，國(guó)際貿(mào)易理論有哪些新發(fā)展，國(guó)際貿(mào)易活動(dòng)有哪些新變化，以及如何對(duì)這些新問(wèn)題進(jìn)行解釋和說(shuō)明。然而由于電子商務(wù)是一種迅速發(fā)展的嶄新的經(jīng)濟(jì)形態(tài)，人們對(duì)它的認(rèn)識(shí)是一個(gè)不斷深化的過(guò)程，也由于本人知識(shí)所限，所以本文更多地是從理論層面闡述電子商務(wù)與國(guó)際貿(mào)易之間的關(guān)系，以期為他人提供一些可供爭(zhēng)辯和討論的問(wèn)題全部業(yè)務(wù)處理過(guò)程轉(zhuǎn)移到網(wǎng)上，從而極大降低企業(yè)成本，提高企業(yè)效率。
