涩北气田泡沫排水采气工艺试验研究

针对气井由于携液不畅导致井筒积液而造成产量下降的问题,涩北气田开展了泡沫排水工艺现场试验研究。根据泡沫排水工艺的基本原理,结合涩北气田的地质特征及地层水矿化度高的特点,开展了泡排剂的室内研究及性能评价,并根据气井的特点进行了大量现场试验。结果表明,泡沫排水采气工艺的实施能够达到排出井筒积液、降低气井油套压差和恢复气井产量的目的。

Experimental Study on Foam-drainage Gas-production Technology for Sebei Gasfield

In some wells of Sebei gasfield, poor liquid-carrying capacity results in a liquid loading, and finally makes a production decline. So, an experimental study on foam-drainage gas-production technology is implemented. Based on the technological principle, the performance of foam-drainage agent is evaluated combining with geological features and formation water with high salinity, and a lot of field tests are simultaneously carried out. Results show that with an obvious economic effect, this technology may el...
