摘要:

利用岩心、薄片、扫描电镜、测井及储层物性等资料,对昆北断阶带基岩储层特征及油气成藏条件等进行了研究。 结果表明: 基岩储层岩性主要为花岗岩和变质板岩;花岗岩主要以溶蚀缝、构造缝和溶蚀孔为储集空间,板岩主要以构造缝为储集空间;基岩油气成藏的有利条件包括良好的油气源,丰富的构造裂缝、溶蚀缝和溶蚀孔等储集空间,多样的圈闭类型和良好的疏导体系;基岩油气成藏的主控因素为多期次活动的断裂和不整合面及之下的风化壳。

Abstract:

Based on core observation, thin section identification, scanning electron microscopy analysis, logging data and physical properties, this paper studied the characteristics of basement reservoirs and hydrocarbon accumulation conditions in the northern Kunlun fault zone. The results indicate that the basement reservoirs are mainly of granite and metamorphic slate, the reservoir spaces of granite are mainly dissolved fractures, tectonic fractures and dissolved pores, and the main reservoir spaces of slate is tectonic fractures. The main conditions of hydrocarbon accumulation in the basement rocks include good source conditions, rich reservoir spaces of tectonic fractures, dissolved fractures and dissolved pores, as well as various traps and good migration system. Multi-stage faults, unconformity surface and weathering crust are the controlling factors of hydrocarbon accumulation.
