Replacement Technology in the Later Stage of Bohai Heavy Oil Multi Cycle Steam Stimulation Well Development
摘要
Abstract
In order to improve the oil well productivity and oil field recovery rate in the later stage of multi-cycle steam stimulation,reservoir engineering methods and numerical simulation methods are used to summarize the pro-duction characteristics of multi cycle steam stimulation.Combined with the geological reservoir characteristics of the oilfield,a steam stimulation replacement plan is studied.The results show that the peak and average production of steam stimulation in the first cycle are twice those of the cold production,and the oil to gas ratio was 3.0,and the average decline rate among multiple cycles was 19.0%.Compared to the conventional steam stimulation,the en-hancement through the combination of chemical agents and gas assistance can increase recovery ratio by 0.4%,lat-eral drilling stimulation can increase recovery ratio by 0.9%,steam stimulation transferring to steam drive can in-crease recovery ratio by 8.7%,and the combination of chemical enhancement and steam drive can increase recov-ery ratio by 9.0%.关键词
