Reservoir characteristics and reservoir-forming model of multi-element hydrocarbon supply in Zhanhua sag
摘要
Abstract
Zhanhua sag has the characteristic of multi-element hydrocarbon supply, which leads to the diversity and complex-ity of reservoir forming. Hydrocarbon accumulation unit of the multi-element hydrocarbon supply was divided by tectonic units combined with oil and gas sources, and dissect the source-reservoir system formation of the dynamic process. The hydrocar-bon accumulation model of different accumulation units was studied. Researches show that Zhanhua sag can be divided into three kinds of hydrocarbon accumulation units, including hollow-one, hollow-multiple and multiple hollow-multiple hydrocar-bons. Along with the establishment of Dongying Formation, the hydrocarbon of the upper part of the Fourth Member of Shahe-jie Formation matured;the single-source lithologic reservoir in the inner subsag and the reservoir in the gentle slope belt star-ted to develop, and the source rocks entered into the hydrocarbon expulsion phase in Minghuazhen Formation. The extensive-ly source-mixed reservoir formed on the steep slope and central low uplift. The translocation system coupled with reservoir-seal assemblage controlled the hydrocarbon distribution of different hydrocarbon accumulation units:the oil and gas migrated extensively from structural low to high on the plane;and oil and gas accumulated in favorable traps of the gentle slope belt,steep slope zone, low salient and buried hills. In the profile, the autogenously lithologic reservoir formed in member 4 and 3 of Shahejie Formation, oil and gas distributed in the thick layer fluvial facies reservoir of Guantao Formation to form reservoirs of the drape structure in Neogene.关键词
