摘要
油田开发中后期,油藏串槽、漏失、出砂严重,导致生产井报废。采用单一的挤水泥浆封漏、封串或封层效果并不理想。针对井下复杂的漏失状况,采用复合封串、封漏技术进行封堵,经现场实测实施取得成功,为封堵作业提供了新的思路。
In the late oilfield development,string slot,dropout,sand producing for reservoirs is serious,leading to the production wells scrapped.Effect of using a single squeeze grout to seal leakage,seal or seal layer is not ideal. According to complex down hole leakage situation,by the use of composite sealing technology,implement of field example sis successful to offer a new idea for plugging operation.
