中文摘要: 油气储层构造应力场的分布特征,对油气运移、注采井网布置、储层改造等具有重要意义。为此,文章从塔河油田AD13井区的地质构造演化入手,基于油田测井资料,结合弹性力学及有限元理论,建立研究区地应力弹性力学计算模型,利用有限元软件对研究区储层地应力进行模拟研究,并将模拟结果与现场地应力实测值进行对比分析。结果表明,研究区最大水平主应力为102~130 MPa,最小水平主应力为87~110 MPa,均为压应力;研究区东部及南部最大水平主应力方向为北东向,西北部最大水平主应力方向为北东东向,西南部最大水平主应力方向为南东向,地应力大小及方向均与实际结果相符。研究结果可为研究区油气勘探开发工程提供科学依据。
Abstract:The distribution characteristics of tectonic stress field in carbonate reservoir are of great significance to the study on oil and gas migration law, reasonable arrangement of injection-production pattern, reservoir transformation, etc. In this paper, starting with the geological tectonic evolution of the Well Block AD13 in the Tahe Oilfield, based on the well logging data, combined with elasticity and finite element theory, the elastic mechanics computational model of crustal stress in the research area is established and the reservoir crustal stress in the research area is simulated by using the finite element software, then the calculated results are compared with the measured values of crustal stress. The results indicate that the maximum horizontal principal stress is 102~130 MPa, the minimum horizontal principal stress is 87~110 MPa, all expressing as compressive stress. The direction of maximum horizontal principal stress in the east and south, northwest, and southwest of the research area are NE, NEE and SE, respectively. The magnitude and direction of crustal stress are consistent with the actual results. The research results can provide a scientific basis for oil and gas exploration and development engineering in the research area.
