摘要
塔里木盆地孔雀河区块发育寒武系 -奥陶系海相和侏罗系陆相两套有效烃源岩构成的复合含油气系统 ;中生界以断裂背斜构造圈闭为主 ,成排成带展布 ;古生界以大型鼻隆背景之上的断背斜、构造岩性、地层不整合圈闭为主 ;控制油气垂向运移的通源断裂发育 ,圈源时空有效配置 ,燕山晚期 -喜山期构造变形微弱 ,有利于油气藏保存。区块内存在三类不同成藏组合的勘探领域 。
Geological conditions are favorable for hydrocarbon accumulation in the Kongquehe area where exists a composite petroleum system with the Cambrian to Ordovician marine sediments and Jurassic continental sediments as effective source rocks. The Paleozoic and Cenozoic are two main exploratory targets. Faulted anticlines are the main structural trap types in Cenozoic while faulted anticlinal, structural lithological and unconformity traps that have developed in large nose-like uplift settings are the main trap types in Paleozoic. Faults that control vertical migration of hydrocarbon are well developed and traps and sources match effectively both in time and space. The weak structural deformation during the late Yanshan and Himalayan periods is favorable for preservation of reservoirs. There are three types of plays in this area with large exploration potentials.
