| 摘 要： | 介绍了徐家围子低渗透油田微生物采油的现场试验。试验采用一组由产气的甲烷茵、分解石蜡的混合杆菌和产生物表面活性剂的芽孢杆菌组成的配伍菌,利用其综合作用解决低渗透油田水驱效果差,油井产量递减率偏高的生产问题。4口试验井已累积增油534.3t,有效期超过110d,投入产出比达到1:2.4以上。为高含蜡原油低渗透油田的增产提供了一条可行的方法。

| Abstract: | field experiment of microbial oil recovery in Xujia weizi low-permeability oilfield is introduced. The compatible bacterium is composed of gas-generated methane bacteria, paraffin-degrading mixed bacteria and bio -surfactant producing bacteria. The interaction of these organisms is designed to solve the problems of poor water-flooding effect and relative high decline rate of oil well production in the low-permeability oilfield. Cumulative incremental oil in four wells is 534. 3t, valid period is over 110 days and input-output ratio is more than 1:2.4. It provides a feasible stimulation for high wax-bearing crude and low permeability oilfield. |
