摘要
生物增效同轴随进复合技术是一项适合特低渗油田改造的一层多缝压裂增产技术,该技术通过在储层中造成更长更多的微裂缝,使生物酶配液与储层或注水层的这些微裂缝有更大面积、体积地结合,通过这种更有效地结合改善储层岩石的润湿状态、降低油—岩层界面张力,在地层压力的作用下,原油从四周裂缝流入井筒,从而提高油井产量。
Composite technology of Biological efficiency and Coaxial Co-Entered is stimulation technique suitable for ultra-low permeability oilfield,through making longer and more micro-cracks,biological enzyme can combine greatly with micro-cracks,which can improve wetting state of reservoir and reduce interfacial tension between oil and rock,by the action of formation pressure,crude oil flows into well from every direction,which will increase oil well production.
