低渗透油田地质开发研究

Study on Geological Development of Low Permeability Oilfields

长庆油田作为中国目前陆地最大油田,其拥有陕甘宁蒙晋五省广阔的开采区域。而大部分开采区域地质条件都为低渗透性地质,为石油开采带来了一定的开采难度。因此对于低渗透油田地质条件下,通过工艺技术改造等生产技术实现油田的生产效益。本文主要针对低渗透油田地质特点和各项工艺技术进行研究并做出一些简单分析。

As China's largest oil field on land,Changqing oilfield has a vast mining area in the five provinces of Shaanxi,Gansu,Ningxia,Mongolia and Shanxi.However,the geological conditions in most mining areas are low permeability geology,which makes it difficult to exploit oil.Therefore,under the geological conditions of low permeability oil fields,the production benefits of oilfields can be realized through technological transformation and other production technologies.This paper mainly studies the geological characteristics and various technologies of low permeability oil fields and makes some simple analysis.
