The Study Of Distribution Of The Residual Oil And Countermeasures Of Taping The Potential In Qinglongtai Oil Field

Because of area, interformation and intrabe conspicuous contradictions, serious reservoir sand, late injection timing and low formation pressure, Qinglongtai oil field is at the stage of high water content and the low-speed development at present. In view of above problem, this article firstly clarifys the type of geological structure, micro-structure, microfacies and reservoir micro-features by comprehensively geological studying on the oil field and fine correlation, and then establishes three-dimensional geological model applying technology of random pattern in modern fine reservoir description technology; secondly this article dynamicly analysises development indicators applying reservoir engineering approach; thirdly this article quantitatively and qualitatively studies distribution of the residual oil applying the way of comprehensive analysis and reservoir simulation technology based on three-dimensional geological model; finally this article identifies ideas and method of tapping potential and formulates feasible adjustment programmes combined to geological characteristics of the development of oil fields and using condition of reserves based on fine reservoir description and the studying on distribution of the residual oil .with the purpose of raising the level of development.
