摘要
彭阳地区长8油藏成藏控制因素不明,影响着彭阳地区勘探开发进度,针对此种现状,结合地震剖面资料运用薄片、相渗、流体包裹体等多种方法综合分析油源、储层特征、成藏主控因素等,分析认为彭阳地区长8油藏油源来自长7,且发育两期油气充注,油藏主要受构造、岩性控制,局部受断裂控制,并结合自生热压裂等储层改造大幅提高了单井产能,可为后续产建开发提供依据。

Abstract
The controlling factors of Chang 8 reservoir in Pengyang area are unknown, which affect the progress of exploration and development in Pengyang area. In view of this situation, combined with seismic profile data, the oil source, reservoir characteristics and main controlling factors of reservoir formation are comprehensively analyzed by means of thin section, phase permeability, fluid inclusion and other methods, The reservoir is mainly controlled by structure and lithology, and partially controlled by faults. Combined with the reservoir reconstruction such as self generated thermal fracturing, the productivity of single well is greatly improved, which can provide the basis for subsequent production, construction and development.
Key words: Pengyang area; Chang 8 reservoir; Reservoir; crack; Hydrocarbon accumulation; Oil source
