GS-高温暂堵剂的研制与应用

Development and application of GS high-temperature temporary blocking agent

针对稠油蒸汽吞吐开采过程中多轮次吞吐后层间及平面矛盾突出的问题 ,通过室内及现场试验 ,研制出一种新型高温暂堵剂。该高温暂堵剂由HG改性树脂、交联剂、HS固相颗粒组成。其成胶温度低 ,基本不受矿化度高低影响 ,强度大、封堵时间可调 。

In view of interlayer and areal problem after multi cycle of huff and puff, a new high temperature temporary blocking agent has been developed through laboratory experiment and field test. This agent consists of HG modified resin, cross linking agent, and HS solid particles. Gelling temperature of the agent is low. It is almost unaffected by salinity, has high strength, and the gelling time is adjustable. It is suitable for temporary blocking in multi cycle huff and puff well.
