摘要利用縱彎褶皺變形中中和面上下巖層的不同應力與應變特點，分析了處于褶皺中和面上下各煤層在背斜與向斜部位煤層厚度、煤層構造、煤體結構及煤層瓦斯的賦存規律與差異性，揭示了這些現象產生的原因。According to the analyses of the research results about the feasibility of 4 - d seismic and the successful 4 - d seismic cases of foreign companies, the author put forward the suggestions for 4 - d seismic pilot area selection ; briefly analyzed the influential function of producing way on the seismic response ; utilized theory calculation, coring data analyses, and reservoir numerical simulation to define the fluid substitution effects on the p - wave velocity. through long time water driven to the reservoir, some of the properties and the log curves have changed, the author tried to find the variation rule of the reservoir and its effects on seismic velocity. the " blind point " in 4 - d seismic feasibility study both in china and overseas was found, that is the lack of consideration of the influence of physical property variation by long time water driven on the seismic response
在深入分析國外四維地震可行性研究成果和成功實例的基礎上，提出了有利於水驅四維地震成功的工區優選條件；簡要剖析了各種開采方式及其對地震特性的影響；利用理論計算、巖心分析、油藏數值模擬三種方法確定了流體替代對縱波速度的影響；通過對長期水驅造成的物性參數、測井曲線以及油藏溫度和壓力變化規律的總結，分析了這些變化對地震速度的影響，指出了目前國內外水驅四維地震可行性研究中存在的盲區?沒有充分考慮長期注水造成的物性、溫度和壓力變化對地震響應的影響，完善了水驅四維地震可行性研究的內容；在考慮了這些變化因素后，高29斷塊水驅四維地震可行性研究結果表明：四維地震監測注水前沿可能要比監測油藏變化容易的多；以四維地震巖石物理可行性研究結果為基礎，提出了五個有助於突出四維地震造成的微小差異的途徑，為今後水驅四維地震研究指明了方向。According to different transverse difference in temperature and lengthways difference in temperature, the paper gave the method of computing temperature effect including : 1 ) the stress ot1 caused by nonlinear difference in temperature. 2 ) the constrain stress o t2 in undetermined structures by equivalent difference in temperature. 3 ) the constrain stress ot3 caused in undetermined structures by even difference in temperature tm
