增韧防窜水泥浆体系的研究与现场应用
|
摘要
针对近年来吐哈油田发生的由于水泥石脆裂所导致油气水窜的问题,我们自主研制了增韧防窜剂,并与室内其它外加剂进行了配伍,优选出增韧防窜水泥浆体系。该水泥浆体系性能稳定,水泥石具有良好的韧性和弹性,防窜能力强,现场施工安全性高,能够满足水平井及小间隙固井要求。该水泥浆体系在水平井鲁平X井、小间隙井柯X井进行了试验应用,取得了良好的效果。
Aiming at the problem of oil gas and water channeling caused by cement embrittlement in Tuha oil field in recent years,we independently developed a toughening and channeling preventive agent, the toughening and channeling-proof cement slurry system was optimized by mixing with other indoor additives. The performance of the toughening and channeling cement slurry system is stable, and the cement has good toughness and elasticity, channeling prevention ability and site construction safety, it can meet the requirements of horizontal well and small clearance cementing.The cement slurry system has obtained the good effect in horizontal well Luping X, small gap well Ke X well tested application.
