摘要
随着延长气田的持续开发和储量动用程度的提高,气藏出水量和出水气井数不断增多,气井井筒积液和出水影响正常生产等问题逐步显现,针对延气2-延128井区的产水问题,优选出适合本区块的MF-1新型泡排剂,实验主要采用罗氏起泡法对该泡排剂的表面张力、耐盐性能、耐温性能以及现场使用进行评价,结果实验表明,该泡排剂MF-1有着较低的临界胶束浓度、较好的耐温、耐盐性能,且在延气2-延128井区三口气井的现场施工中,取得了较好的效果,达到了排水增产的目的。
With the continued development of Yanchang oilfield, the amount of water and the effluent gas wells have increased in the all erea. For the problem of gas well effluent, the technology have selected for the new foam solvent MF-1, the ability of surfactant, the tolerant of salt properties and temperature are measured by the Roche foaming method. The result of the experiment that the MF-1 have lower CMC, heat resistance and salt tolerant, and the MF-1 is succeed in three gas well, achieved good effect to increasing the drainage purposes.
