江汉油区经过40多年的勘探开发,已投入开发的油田27个,形成了一个以内陆盐湖沉积背景下的江汉油区。本次分析了江汉油区的水驱趋势、开发水平、开发指标和开发阶段四个方面开发形式,结合未动用储量技术经济评价,指出今后需要重点攻关的目标主要包括:对“双高”及高含水单元,搞清储层宏观、微观、渗流参数和剩余油分布的变化;对难采储量,对目前的钻采工艺适应性差,需要采取特殊的管理机制,依靠科技进步,逐渐动用。
After more than 40 years of exploration and development, Jianghan Oilfield has put into operation 27 oilfields, forming a Jianghan oilfield under the background of inland salt lake sedimentation. This paper analyzes the development trend of water flooding, development level, development index and development stage in Jianghan oil region. Based on the technical and economic evaluation of unused reserves, it points out that the targets that need to be tackled in the future mainly include: "And high water-cut units to find out the changes of macroscopic, microscopic, seepage parameters and remaining oil distribution in reservoirs. For difficult-to-reclaim reserves and poor adaptability to the current drilling technology, special management mechanisms need to be adopted and technological progress is gradually applied .
