为提高稠油高轮次吞吐井后期开发效果,根据油井的不同原油物性、不同地层压力等情况,有针对性的研制与应用的两种稠油高轮次吞吐井复合驱油技术,解决了稠油进入高轮次吞吐后,由于层间矛盾突出、地层压力下降、原油粘度升高、地下存水增加等原因导致的稠油周期产量大幅度降低的问题,有效改善了高轮次井吞吐效果,提高了稠油采收率。
In order to improve the post-development effect of high-throughput wells with heavy oil, according to different oil physical properties of the oil well and different formation pressures, two kinds of heavy oil and high throughput wells were developed and applied to solve the problems of Heavy oil into the high-round after the throughput, due to prominent conflicts between layers, formation pressure drops, the viscosity of crude oil, increased underground storage and other causes of heavy oil cycle significantly reduced the yield, effectively improving the high round well huff and puff Effect, increased heavy oil recovery.
