摘要
我国低渗透油气资源十分丰富,边水与底水驱动不明显,天然的能量补给较差,增加了开发难度。随着石油的不断开采,国内大多数油田需要采取注水开发以保持地层压力,达到提升最终采收率的目的。对这些注水开发油藏,如何评价注水开发效果,到目前为止,还几乎没有系统完善的方法。在充分调研的基础上,对现阶段油田注水开发效果的评价方法进行了归纳分析。
China's low-permeability oil and gas resources are very rich,edge water and bottom water driving is not obvious,the natural energy supply is poor,all of those increase the difficulty of development.With the continuous exploitation of oil,the majority of domestic oil fields need water injection development to maintain formation pressure and enhance the ultimate recovery.So far,there are few systematic methods to evaluate the effect of water injection development.On the basis of full investigation,the evaluation method of water injection effect of oilfield at present is summarized and analyzed.
