Comprehensive management of Ordovician reservoir in 6th block of Tahe Oil Field

摘要: 塔河油田六区奥陶系油藏自2007年底以来因含水上升导致递减加大,开发效果明显变差;2009年5月开始进行油田综合治理,因含水上升是影响开发效果变差的主要因素,治理目标为稳油控水,确保油田稳产。针对塔河油田奥陶系碳酸盐岩油藏以缝洞为储集体的特点,通过对不同多井缝洞单元储层发育特征、油藏开发特征研究,根据不同缝洞单元含水上升特点,理清治理思路,制定了不同的治理对策。文中主要介绍典型堵水单元S66单元和典型注水单元S74单元的实施效果。Abstract: Since the end of 2007,production has been decreasing due to theincrease of water contentinOrdovician reservoirin the 6th block of the Tahe Oil Field.Since May of 2009,comprehensive management has been carried outaiming at water control and production stabilization.As to Ordovician carbonate accumulation in the Tahe Oil Fieldpores and fractures work as reservoir.Characteristics of pore-and-fracture reservoir generationing treatments were put forward.Inand exploration in different wells were studied,and the correspondunits S66(water shutoff) and S74(water injected),the manage ment was practiced.
