Using Comprehensive Analysis Method of Reservoir Engineering Studies Remaining Oil Distribution Regular A Case from OL Oilfield——QIULIN OILFIELD

Jing Yin

Abstract

Now QL oilfield has been in the high water cut stage of development since putting into full water injection in 1995.The stable production and production Potential in oilfield become more and more difficult because of complex relationship between oil and water in underground with deepening production.It is significant to deepen the remaining oil distribution research in the high water cut stage.This paper adopts comprehensive analysis method of reservoir engineering to further study the remaining oil distribution of QL oilfield.Finlly,the underground oil and water movement and the remaining oil area was showed in the form of oil-water distribution plan in plane.It provides an important basis for Secondary development and potential adjustment in oilfield.
