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.
Based on the actual data of Luxi Sag, the role of fractures in oil and gas exploration and the characteristics of different types of fractures are analyzed. The factors influencing the development of tectonic fractures are analyzed. The development of tectonic fractures is affected by the structural parts, porosity and faults The quantitative relationship between the degree of fracture development and related influencing factors was discussed. The method of fitting the curvature and the method of calculating the distance to the nearest fault were given, and a quantitative prediction method of fracture density Curvature prediction method and the corresponding evaluation criteria, and predict the distribution of fractures in Luxi Depression.
