摘要
林樊家油田林东馆三段地质条件复杂,地层敏感性强,供液差,产能低,油稠,出砂严重,多年来采用了各种工艺措施,均未取得好的水驱开采效果。文章运用数值模拟手段,分析了低水驱的主要原因和论证了低效水驱转蒸汽热采可行性。在此基础上,研究了该块低效水驱转蒸汽热采的开发经济技术政策界限。开发实践表明,低效水驱稠油油藏通过转热采可大幅提高采收率,同时研究成果对同类油藏的开发具有重要指导意义。
Lindong reservoir of the third member of Guantao Formation in Linfanjia Oilfield has the characteristics of complicated geological condi- tions, sensitive formation, poor liquid supplying capacity, low production capacity, heavy oil, serious sand production, etc. Therefore good water flooding development results were not obtained through using various techniques. Taking Lindong Reservoir of the third member of Guantao Formation in Linfanjia Oilfield as the example, and with the help of numerical simulaton method, the feasibility of steam injection after low efficiency water flooding was studied through the analysis of main factor controlling water flooding in heavy oil reservoir. Based on that, the economic and technical policy limitation of thermal development after low efficiency water flooding was studied. The field applications show that a good result has been obtained, and the research provides a basis for exploitation in this block and in the same type of oil reservoirs.
