稠油蒸汽吞吐开采中表面活性剂的筛选和性能评价

The Screening and Evaluation of Performance of the Surfactant in Heavy oil Cyclic Steam Stimulation

在稠油开采中,表面活性剂一般作为蒸汽吞吐的一种辅助注入剂,其表面张力、发泡率及配伍性等性能指标对稠油开采起到一定的影响作用。室内对四种表面活性剂1#、2#3、#、4#的表面张力、发泡能力、泡沫质量及配伍性等性能进行了性能评价。综合对比四种表面活性剂的性能评价结果,最终选择2#表面活性剂作为辅助添加剂。

In heavy oil recovery,the surfactant is usually used as an auxiliary additive in the cyclic steam stimulation.The boundary tension、foaming capacity and compatibility and other correlation behavior index have some influence on heavy oil recovery.Interior,the boundary tension 、foaming capacity、foam quality and compatibility of 1#、2#、3#、4# surfactant have been evaluated.Synthetical contrasts the results of the four surfactants evaluation of performance,chooses the 2# surfactant to be the auxiliary additive.
