地应力场作用下优质储层主要集中在应力较弱的层段,与油气运移配置较好时就形成油气藏。在此基础上初步建立了地应力场下泥岩电阻率与油气层的判别标准,通过对焉耆盆地地应力场研究认为,种马场构造带地应力最强,其次是南部凹陷,北部凹陷较弱。研究结果为下步焉耆盆地展开勘探提供了依据。 Under the action of geostress field, the high-quality reservoirs are mainly concentrated in the layers with weaker stress, forming the reservoirs when the hydrocarbon migration and distribution are better. On this basis, the criteria of determining the resistivity of mudstone and hydrocarbon reservoir under the stress field are preliminarily established. According to the study of the geostress field in Yanqi Basin, the stress of the stratum field is strongest, followed by the southern depression and the northern depression. The results provide the basis for further exploration in Yanqi Basin.
