摘要
探讨了PB-1型多功能屏蔽暂堵剂的防漏堵漏及保护油气层的作用机理,并对其影响钻井液性能的程度进行了室内试验。在新疆塔里木和柴窝铺、西藏伦坡拉、吉林松南等油气勘探开发区的现场应用表明,该暂堵剂防漏、堵漏、保护油气层效果显著,防漏成功率达100%,堵漏成功率达90%,取得了较好的技术经济效益。
The paper discusses the plugging mechanism of PB1 multifunctional shieding temporary plugging agent for antileakage,loss circulation control and oil & gas reservior protection,the lab tests on its effect to drilling fluid performance were conducted.The applications in Tarim,Chaiwopu,Lunpola and Songnan Oilfields show that its effectiveness is remarkable,the success rate of antileakage and loss circulation control is 100% and 90%,respectively.
