稠油降粘技术在采油工艺上的应用

针对高粘稠油开采中的一些实际问题，开发研制了CJ-128稠油油溶性降粘剂。通过管流实验的测定，对比分析了该降粘剂的降粘效果，实验结果表明，随着添加CJ-128降粘剂比例增大，降粘幅度也加大。同时，随着稠油含水率加大，其降粘幅度减小。用CJ-128稠油降粘剂采油，井下油温不低于50℃时，每采1吨油，只需加入5％即50kg的降粘剂。由于降粘剂与稠油互溶，所加入5％的降粘剂与稠油一起可全部采出地面，一方面可直接增加5％的采油产量，另一方面降低了采油成本。

Application of Decreasing Viscosity Technique of Heavy Oil on Crude Production

According to some practical problems , CJ-128 heavy oil lipid solubility decreasing viscosity agent was exploited and developed. Through the measurement of pipe line flowing experiment, the effect of decreasing viscosity was analysed, the experiment results showed that decreasing viscosity amplitude was enlarged with increasing the proportion of CJ-128 which was added, at the same time, the decreasing viscosity amplitude was decreased with increasing the moisture content of heavy oil. Using CJ-128 heavy oil decreasing viscosity agent, on one hand, can increase crude production output over 5 percenta, on the other hand, the cost of crude production will decrease.
