黄场油田潜4^(3)开发调整对策研究

Study on Development Adjustment Strategies of Qian4^(3) In Huangchang Oilfield

黄场油田潜4^(3)油组地层自西向东抬高,构造属于单倾斜坡,为岩性和构造岩性油藏。经过多年的开发,油水井井损导致井网控制程度低,同时注入水沿裂缝推进,含水持续上升,产量下降快。基于目前黄场油田潜4^(3)油组开发状况,以油区为对象,制定分区治理对策,改善开发效果。

The Qian4^(3) oil group in Huangchang oilfield is elevated from west to east,with the structure pertaining to a single dip slope,which is a lithologic and structural-lithologic reservoir.After years of development,the well loss of oil and water wells has led to low control of well pattern.Meanwhile,the injected water pushes along fractures,the water cut continues to rise,and the production declines rapidly.Based on the current development status of Qian4^(3) oil group in Huangchang oilfield,this paper takes the oil area as the object to formulate the zoning control strategy to improve the development effect.
