随着轮南油田地层能量不断衰竭,大部分油井已经进入低压、低产阶段,常规柱塞气举井产量低、携液效率低,且该工艺间歇性开关井制度制定不合理时易导致井筒积液压死油层,造成经济损失。为了解决上述问题,通过室内研究与现场试验,采用多项工艺相结合的方式研发出一套"固定式多级气举阀管柱+浮动式中空快速柱塞+清蜡柱塞"相结合的复合柱塞气举新工艺。该工艺在前期柱塞气举技术的基础上进行了创新,实现了不关井连续生产,避免井筒积液,现场应用4井次共减少清蜡作业次数147次、减少制氮车气举作业LNA井2次、LNB井1次,并且复合柱塞运行增油1 096 t。复合柱塞气举新工艺现场应用效果明显,已逐步在油田进行推广,实现柱塞气举井高效生产。
