化学堵剂封层技术是在油气田开发生产过程中应用得较多的层系调整方式,堵剂的性能直接决定了封层效果。本文介绍的TT-DJ复合调堵剂是由悬浮剂、增强剂、增韧剂和胶凝材料组成的新型堵剂。通过TT-DJ复合调堵剂与其他堵剂的实验对比和现场应用,表明TT-DJ复合调堵剂具有温度适应性强、稠化时间长、流变性能好、界面胶结强度高等特点,可以满足冀东油田陆上作业区在油水气井套管破损、地层漏失、炮眼封堵、层位封堵各方面的应用。
Chemical blocking agent sealing technology is applied in the development and production of oil and gas fields more stratified adjustment methods, blocking agent properties directly determine the sealing effect. This article describes the TT-DJ complex plugging agent is a new type of plugging agent composed of suspending agent, reinforcing agent, toughening agent and cementitious material. Through the comparison of TT-DJ compound plugging agent with other plugging agents and field application, it shows that TT-DJ compound plugging plugging agent has the characteristics of strong temperature adaptability, thickening time, good rheological property and high interface cementation strength, Jidong Oilfield to meet the land-based area in the oil and gas wells casing damage, formation loss, borehole closure, stratification of the application of various aspects.
