摘要
介绍以ＴＤＧ－ＩＲ和ＴＦ－３主要组份的选择性堵水剂，研究了影响堵水剂性能的有关因素。模拟油藏物化条件和现场试验证明，该堵水剂对油和水有选择性，抗压强度大，施工时基液粘度小，可携带各种固体填料，温度适应范围宽，成胶时间可调，工艺简单，有效期较长，是目前国内性能较好的一种新型堵水剂。
Alternative water shutoff agents comprising TDG-IR and TF-3 as main components are presented.Also presented are the studied relevant factors affecting the performance of water shutoff agents.Both sirnulations of reservoirs physicochemical conditions and tests in-site of oilfields prove that this type of water shutoff agents has the alternative of water and oil and the high compressive strength and low viscosity of base liquid during the water shutoff job.They were also proved to be capable of carrying all kinds of solid filling materials and adapting themselves to a broad range of temperatures,to have the possibility of readjusting gelification time and the simplicity of application process and the relatively long effective period.They represent today a new type of domestic water shutoff agents with better performance.
