摘　　要：从陆西凹陷的实际资料出发,分析了裂缝在油气勘探中的作用及不同类型裂缝的特征,研究了影响构造裂缝发育的因素,认为构造裂缝的发育受构造部位、孔隙度、断层等多种因素的影响,探讨了裂缝发育程度与相关影响因素之间的定量关系,给出了拟合求曲率的方法、与最近断层距离的计算方法,建立了裂缝密度的定量化预测方法——拟合曲率综合预测裂缝方法和相应的评价标准,并对陆西凹陷的裂缝分布进行预测.On the basis of practical data in Luxi Sag, the action of fractures in oil and gas exploration and the characteristics of different kinds of fractures have been analyzed. The factors that affected the development of structural fracture are investigated. The authors suggest that the development was affected by structural position, porosity and fault, etc. By quantitatively investigating the relation between the development degree of fractures and the above factors, the regressive method to work out the curvature and the method to calculate the distance from the reference point to the nearest fault are put forward. The integrated method for forecasting fracture using regressive curvature is established, and its evaluation standard associated is also put forward. According to this method, the forecast of fracture distribution in Luxi Sag is carried out.
