摘要： 根据野外地面裂缝调查、岩心裂缝观察描述及测井裂缝识别,指出川东五百梯气田致密储集层主要是受局部构造控制的构造缝。结合实验分析认为,岩石物性、岩石本身的力学性质及构造变形应力场强度是控制其裂缝发育的主要地质因素。研究区的裂缝可以划分为成岩微裂隙、风化裂隙和构造裂缝3种类型。根据研究区实际地质情况,采用构造应力模拟方法,对研究区构造裂缝发育进行了初步评价。

Abstract: Based on the field geologic survey, core observation and well logging fractural identification, it is shown that in the tight reservoir in Wubaiti gas pool of eastern Sichuan developed structural fractures controlled by local structure. Experimental analysis indicates that petrophysical property, dynamic nature of rocks and stress field intensity of structural deformation are the main geologic factors controlling the fractural development in this area. The fracture in studied area can be divided into diagenetic micro-facture, weathering fracture and structural fracture. According to real geologic situation, the preliminary evaluation of the structural fracture development in the studied area is conducted by means of structural stress simulation method in this paper.
