Abstract: In accordance with lithotype and its structural condition,the structural fractured hydro-carbon reservoir is clasified into four categories,including 13 types of traps,which are distributed in four types of petroliferous basins. In craton basins formed pre-Alpine phase,it isfavorable to form the structural fractured reservoirs in the region where carbonates mainlydeveloped in which the seals exist.During the Alpine phase an upper oil-bearing assemblageof the continental deposits was forrned in the subsidence inland basins of western China,inwhich the structural fractured reservoirs occur locally, while in a lower oil-bearing asserm-blage developed in the giant petroliferous basins,the structural fractured reservoirs have better prospects. In the craton-foredeep basin of central China,exploration for these reservoirs inthe lower assemblage has made a remarkable headway,but only those filled with coal-gere-nating gas occur in the upper assernblage. In the fault basins of eastern China,there are somestructural fractured reservoirs in the upper assemblage under special structural conditions.Thus,the structured fractural hvdrocarbon reservoirs are widespread.In the region associatedwith older uplift,specifically those with seal,it is an ideal place to look for gaint oil accumu-lation in the structural fractured reservoirs.

摘要: 构造-裂缝油气藏,根据储层的岩石类型和构造条件,可划分为四大类12种圈闭,分布在两种构造体制形成的四类含油盆地中.在前阿尔卑斯期的克拉通盆地内,以海相碳酸盐岩为主,封闭保存条件较好的地区,可能是构造一裂缝油气藏发育的有利场所.阿尔卑斯期在西部内陆坳陷盆地内,陆相上部含油组合形成部分的构造-裂缝油气藏,而下部海相含油组合发育的大型含油盆地内,构造-裂缝油气藏有较好的前景.在中部克拉通一前渊盆地中,下部海相含油组合的构造-裂缝油气藏取得了突破性的进展,上部陆相含油组合发育以煤成气为主的少量构造-裂缝油气藏.在东部的裂陷盆地内,上部陆柏含油组合在特定地质条件下发育了一定的构造一裂缝油气藏.构造-裂缝油气藏分布较广,特别是封闭保存条件较好的古隆起,是寻找大型构造一裂缝油气藏的理想场所.
