裂缝性油气藏储层是指以裂缝、溶蚀孔隙为主要储集条件的湖相暗色细粒沉积岩构成的储层。狮子沟构造自1984年在下干柴沟组(E_3)中获得高产工业油气流后成为柴达木盆地典型的裂缝性油气藏之一,近年来对裂缝性油气藏储层及油气富集规律的研究与评价越来越受到重视。本文通过对狮子沟中深层(N_1-E_(1+2))裂缝性油气储层的研究认为其特征主要体现在岩性及其储集性、物性、含油气性及其电性特征上,其储层的发育和分布主要受岩性和断层控制,油气藏主要为自生自储的断层裂缝圈闭油气藏和背斜裂缝圈闭油气藏,油气的富集受油源条件、储集条件、圈闭条件和保存条件等因素控制。
The fractured reservoirs are those reservoirs composed of lacustrine dark fine-grained sedimentary rocks with fractures and dissolved pores as the main reservoir conditions. Since 1984, the Shizigou structure became one of the typical fractured reservoirs in the Qaidam Basin after obtaining high production industrial oil and gas flow in the Lower Ganchaigou Formation (E_3). In recent years, the laws of the reservoirs and hydrocarbon enrichment in fractured reservoirs Research and evaluation more and more attention. Based on the study of deep (N_1-E_ (1 + 2)) fractured reservoirs in Shizigou, this paper argues that its characteristics are mainly reflected in its lithology, reservoir properties, physical properties, hydrocarbon bearing and its electrical characteristics, The development and distribution of its reservoirs are mainly controlled by lithology and faults. The reservoirs are mainly self-generating self-storage fault fractured trap reservoirs and anticline fractures trapped reservoirs. The enrichment of oil and gas is controlled by oil source conditions, reservoir conditions , Trapping conditions and preservation conditions and other factors control.
