【摘要】 在户部寨地区区域地质特征研究基础上,运用地质成因的应力应变分析方法,利用3DMove裂缝预测技术对沙河街组沙四段的裂缝分布进行了预测,并对不同方向裂缝的开启程度进行了分析。实践证明,裂缝预测和开启性评价结果与实际钻井情况基本吻合,对该区以构造成因为主的裂缝油气藏的勘探和开发具有一定的指导意义。更多还原

【Abstract】 This paper predicts the distribution of fractures in the fourth member of Shahejie formation in Hubuzhai area and analyzes the aperture of fractures in different directions on the basis of regional geological study through geological stress-strain analysis by using 3DMove fracture prediction technology.It has been proved by practice that the result of fracture prediction and aperture evaluation almost tallies with actual drilling result.This can be used to guide the exploration and development of fractured reservoirs of tectonic genesis in this area.更多还原
