经历了30多年的开发,胜坨油田已经进入了特高含水开发后期,调整和挖潜的难度增大,在非均质油藏中,潜力往往分布于压力水平较低的层段,从压力状况入手分析油藏潜力是一种新的尝试。通过对胜坨油田二区83-5单元地层压力状况的分析,指导特高期油藏调整挖潜,在开发实践中取得了较好的效果,对进入特高含水后期的老油田的开发有一定参考价值。
After more than 30 years of development, Shengtuo Oilfield has entered the later stage of ultra-high water-cut development. It is more difficult to adjust and tap potential. In heterogeneous reservoirs, potential is often distributed in lower pressure levels. From the pressure conditions It is a new attempt to analyze the reservoir potential. Based on the analysis of the formation pressure in Unit 83-5 of the second district of Shengtuo Oilfield to guide the adjustment and tapping potential of the reservoir in the special high period, good results have been obtained in the practice of development and there is a certain development in the old oilfield entering the latter part of the ultra-high water cut Reference value.
