陆梁水驱油藏内源微生物激活配方优化及性能
|
摘要
针对陆梁油田陆9井区边底水油藏特性,运用聚合物驱等方法提高采收率在该油藏中受限;采用最大可能数法(MPN)分析油藏产出液中微生物四类菌浓度及分析了油藏地层水的离子组成;确定了激活内源微生物的激活思路。确定以菌浓、原油乳化效果和界面张力作为优化激活剂配方评价的依据;并以物理模拟实验为指导,通过调整激活剂中蔗糖、钠盐的浓度,比较激活剂是否注气两种方式;优化了激活剂配比,进行了激活效果评价实验。结果表明,对于陆梁油田陆9井区油藏,在一定范围内,提高激活剂中蔗糖、钠盐的含量,注入空气,可以有效提高微生物驱采收率;其中激活剂体系优化选择质量分数0. 55%的蔗糖、质量分数0. 6%钠盐,可提高驱油效率6. 45%,能较好满足生产效益,为陆梁油田陆9井区开展内源微生物驱提供了可靠的室内实验依据。
Based on the characteristics of edge water reservoirs and bottom water reservoirs in the Lu 9 well district of Luliang Oilfield,polymer flooding and other methods were used to improve the recovery rate and avoid the limitation in the reservoirs. The concentration of four kinds of microorganisms in reservoir production fluid and ion composition of reservoir formation water are analyzed by maximum probability number method( MPN),and the activation thought of activating endogenous microorganisms was determined. Based on bacterial concentration,emulsifying effect of crude oil and interfacial tension as the basis of optimizing activator formulation,and under the guidance of physical simulation experiment,the ratio of activator was optimized by adjusting the concentration of sucrose and sodium salt in activator and comparing whether the activator injected gas or not. The results show that for Lu9 well area of Luliang oilfield,in a certain range,increasing the content of sucrose and sodium salt in activator and injecting air can effectively improve microbial flooding recovery. The optimum selection of sucrose with 0. 55%mass fraction and sodium salt with 0. 6% mass fraction in activator system can improve oil displacement efficiency by 6. 45%,which is comparable to that of other methods. In order to meet the production benefits,reliable laboratory experimental basis is provided for the development of endogenous microbial flooding in Lu9 well area of Luliang oilfield.
