济阳坳陷平方王油田碳酸盐岩潜山内幕储层特征及其主控因素
Characteristics and main controlling factors of layered reservoir in buried hill of carbonate rock in Pingfangwang Oilfield, Jiyang Depression
摘要
Abstract
Favorable reservoir prediction is one of the important factors that control the current exploration from hilltop to in-ner reservoir in the buried hill of the ower Paleozoic carbonate. Taking the Lower Paleozoic buried hill in Pingfangwang Oil-field of Jiyang Depression as the study area, we combined element geochemistry, mineralogy, and core routine analysis to carry out a series of study. We analyzed the genetic type of the inner reservoir space, defined the master control factors of the reservoir, and established the reservoir development model. The results show that different types of carbonate developed in the Lower Paleozoic formed the basis of the inner reservoir. The inner reservoir has three different reservoir spaces including solution pore space-cracks, tectonic fractures, and primary pores, which suggests that the formation of the reservoir is con-trolled by rock type, tectonization and fluidization. Rock type is the basic factor controlling the number of primary pores, which further affects the solution-resistance of associated rocks and the development of tectonic fractures. Tectonization de-gree is a key factor. Tectonic fractures have a positive correlation with solution pore space-cracks. Fluidization degree is the crucial factor. A large number of pore spaces, micropores and microcracks can form through corrosion of deep hypothermal solution and organic acid, which greatly improves the reservoir property.关键词
