胜利油区主要有3种不同类型的火成岩岩体,均能成为有效储层。不同类型的火成岩具有不同的相带划分模式,而相带又决定了火成岩体中原生孔隙的发育规律,影响着后期的构造形变、断裂破碎对火成岩储层的改善程度,是控制储层性质的基本因素之一。通过胜利油区3种不同类型的储油火成岩,即侵入岩、火山碎屑岩、溢流玄武岩的相带划分研究,对火成岩储层发育的有利区进行初步分析,为火成岩储层的综合评价奠定基础。
There are mainly 3 different types of igneous rocks in Shengli Oilfield, all of which can become effective reservoirs. Different types of igneous rocks have different facies division patterns, and facies belts determine the developmental rules of primary pores in igneous rocks and affect the later tectonic deformation. The improvement of igneous rocks by fractures is controlled by reservoir properties One of the basic factors. Through the study on the facies division of three different types of oil-bearing igneous rocks in Shengli oilfield, that is, intrusive rocks, volcaniclastic rocks and overflowing basalts, the favorable zones for the development of igneous rocks are preliminarily analyzed, which is the comprehensive evaluation of igneous reservoirs Lay the foundation.
