摘要
随着曙光油田稀油注水开发的不断深入,油层污染堵塞问题愈加严重,已成为影响油田开发效果的主要矛盾之一。同时地层亏空严重,传统解堵工艺的局限性日渐凸显。气体增能解堵技术,通过充分分析油藏伤害机理及油藏物性特征,选取适合曙光油田稀油生产特点的复合解堵工艺,可达到补充地层能量,有效解除油层伤害,保证油井正常生产,改善稀油开发效果的目的。
With the exploration of thin oil water injection, the pollution and plugging to the reservoir in Shuguang Oilfield have become more serious, which has been one of the main problems that affect the development of the oil-field. Meanwhile, the limits of conventional plugging removal technologies are emerging with the seriously depletion of the reservoir. By fully analyzing the mechanism of injuries and the properties of the reservoir and selecting the complex plugging removal technologies suitable of thin oil production in Shuguang Oil-field, the gas energizing plugging removal technology can supplement the energy and eliminate effectively the injuries of the reservoir so as to keep the oil well operation in order and improve the developing effects of thin oil.
