摘要
为有效地解除细粉砂油藏近井地带的堵塞,根据排砂采油工艺技术原理,对携砂敏感性及排砂采油技术应用适应性进行分析,总结了滨南、纯梁、孤东等采油厂不同类型出砂油藏现场试验情况,根据应用中存在的问题开展了配套防砂或不防砂的政策界限研究及采用排砂采油技术时挡砂精度的匹配分析,确定了该技术的适用条件。现场应用结果表明,该技术可使油层恢复原有的渗透性,使油井恢复原始产能。
In order to remove near wellbore blocking in fine sihstone reservoirs,Shengli Oilfield analyzes solid - carrying sensitivity and the technical adaptiveness of sand dump producing technology,generalizes the result of field tests in various sanding reservoirs of Binnan,Chunliang and Gudong Oil Production Plants,studies the stra- tegic limits of necessary sand control or no sand control,analyzes the allocation accuracy of sand retention when applying sand dump producing technology,and identifies applicable conditions.The results of field application indicate that this technology can restore original reservoir permeability and oil well productivity.
