摘要
氮气注入方式有氮气-水交替注入、氮气-水脉冲注入和氮气吞吐等。氮气吞吐工艺简单易行,投资少,见效快。简述了氮气吞吐开采机理,室内试验研究了合理的氮气吞吐工艺参数,并采用表面活性剂辅助氮气吞吐改善后续周期吞吐效果。现场试验结果表明,表面活性剂辅助氮气吞吐是一种可行的注氮气开采方式。
Abstract
The fashion of nitrogen injection includes nitrogen-water injection alternately, nitrogen-water injection with impulse and nitrogen soaking. Nitrogen soaking is simple and easier done, lower cost and quicker effect. The mechanism of nitrogen soaking is narrated briefly. Lab tests have been done to study the technology parameter of nitrogen soaking, and using surfactant to improve the effect of later stage. Field test shows nitrogen soaking technology with surfactant assistant is a feasible fashion of nitrogen injection.
