摘　　要：CXG型堵漏剂是一种新型的堵漏封窜剂,该堵剂在常用的油井水泥基础上,添加了具有活性组分的支撑剂、悬浮分散剂和固化剂。室内及现场试验表明,CXG型堵漏剂具有热稳定性好、固结体强度高、可实现等体积固结和自愈合等性能,对不同渗透率岩心均具有较强的封堵能力,可用于封堵管外窜、裂缝、高渗透层及地层大孔道,并已在胜利孤岛油田现场应用中获得成功,具有广阔的应用前景。CXG is a newly developed plugging agent,which is developed by adding proppant with active components,suspended dispersant and hardening agent into the traditional cement.The results in lab and field test indicate that CXG has the good properties of heat stability,high intensity,concretion and concrescence at the same volume.It can plug cores with different permeability.Therefore,it can be used in the plug of channeling,fracture,thief zone,channel,etc.And it is successfully applid in Gudao oilfield.This paper mainly introduces the experiment study and field test of CXG.
