基于灰色关联的油藏开发效果评价及治理对策研究——以姬塬油田Y267侏罗系油藏为例
|
摘要
姬塬油田Y267区发育侏罗系延8、延9、延10三个油藏的规模较小、含油带窄、边底水发育,目前油藏整体进入中高含水期,存在底水锥进现象明显、剖面矛盾突出、低产井逐年增加等开发矛盾,后期稳产难度逐年加大。应用灰色关联综合评价技术对油藏水驱开发效果进行评价,运用三维地质建模和数值模拟对剩余油分布及潜力进行分析,结合静态地质研究及油藏动态,针对油藏存在的主要开发矛盾,制定相应的开发调整对策,在此基础上对不同对策方案进行模拟并优选最佳开发方案,为油田后期的整体调整以及同类油藏的开发调整提供了一定的借鉴作用。
The Jurassic reservoir of Y267-Block is located in Tiebiancheng of JiYuan oilfield,which is a small scale edge/bottom water reservoir with narrow oil sand band.From 2009,the progressive development is used in this reservoir with the stages of'fast drilling-waterflood-sustained production'.Currently,this reservoir is in high water-cut development period,and the difficulty of stable production in the later period is increasing year by year.Aiming at the production status and the existent problem,the grey comprehensive evaluation technique is used to evaluate the influencing factors and development effects of oil field water driving.The remaining oil distribution and development potential of the reservoir are evaluated with the aid of three-dimensional geological modeling and numerical simulation.Combining the static geologic research with the reservoir performance,researchers make the corresponding developing plans to solve the primary development problem.These plans are simulated and the best option has been recommended,which provides a basis for the overall development adjustment,and is helpful for the same kind of oil reservoirs.
