摘要

在对车排子地区单井层序、连井层序研究的基础上,以地震地层学为指导,进行精细的井—震标定,结合车89井区的属性分析,认为该井区沙湾组油气层的地震响应为亮点,但不可逆。而构造与岩性地层构成典型的"反向屋脊断块",断裂平面上呈现的弧形特征才是含油气更为有利的区域,构造与岩性及其配置关系共同控制着研究区的油气成藏。
Guided by seismic stratigraphy, the fine well-seismic calibration is implemented according to the research on both single-well and continuous-well sequences. Moreover, combined with attribute analysis of Che 89 well block in Chepaizi area, it is found that, from the view of seismic response, the oil and gas layers from Shawan Formation represent bright spot. For a traditional reverse roof fault block formed by structural and lithologic strata, its fracture surface, which shows in an arc, is just the more favorable zone. Two factors of both structure and lithology and their relation affect reservoir accumulation.
