Optimization Study on Cleanup Scheme of Steam Stimulation in Heavy Oil Reservoirs
摘要
Abstract
Mixing effective cleanup additive agent with steam can improve the production performance of steam stimulation in heavy oil reservoirs,because it can expand the swept volume of steam and play a role of profile control,and then solve the problems of formation energy dropping and steam channeling.The optimization study on cleanup scheme of steam stimulation was studied taking the D1 1 block in J oilfield to be the research object.Firstly,the results of static performance evaluation indicated that the selected foaming agent served good performance and adaptability to this block,and then the proposed cleanup patterns were preliminarily screened through physical simulation experiments in which various additives were injected with steam simultaneously.Secondly,next screening tests were carried out with the numerical simulation method and the economic benefits analysis,and the results showed that the foaming agent assisted steam stimulation has the most increased oil and the best economic benefit,which was the best preferable cleanup pattern of steam stimulation for this block.Finally,the optimum schemes of selected cleanup pattern with the most increased oil and the best economic benefit were obtained respectively by optimal designing of injection parameters.This study provided a way to improve the development effect of steam stimulation in this block,and was helpful for the development of similar reservoirs.关键词
