废弃钻井液调剖堵水剂的制备与研究
|
摘要
针对油田废弃钻井液的处理问题,提出了向废弃钻井液中加入添加剂,制成一种废弃钻井液调剖剂。室内实验通过分析废弃钻井液的物性及粒径,筛选出适合的调剖剂配方。实验表明各添加剂的最优加量为:悬浮剂0.2%,分散剂0.3%,固化剂5.0%。所制备的废弃钻井液调剖剂具有良好的悬浮稳定性、固化性能和封堵性能,不仅解决了废弃钻井液的处理问题,而且降低了堵水剂的生产成本,对油田的生产有着重要意义。
In order to deal with the waste drilling fluid in Jiangsu oilfield, we proposed to add additives to the waste drilling fluid,and made a kind of waste drilling fluid profile control agent. In the laboratory experiments, by the physical properties of waste drilling fluid and particle size, we filtered out the suitable profile control formula. Then we obtained the optimum dosage of each additive from the experiments: the suspension of 0.20 %, dispersant 0.30 % and curing agent 5.0 %. The developed waste drilling fluid profile control agent had good suspension stability, curing properties and plugging performance. It could not only solve the problemsof waste drilling fluid, but also reduced the production cost of plugging agent, moreover, it had great significance to the production of oil.
