摘    要:为了探索水驱前后储层微观变化规律,指导油田注水开发,以探井和开发中后期检查井的岩心分析数据为基础,采用储层地质学和开发地质学的基本原理和方法,研究了港东开发区水淹前后储层参数变化规律。总体表明,水淹后次生粒间孔隙更加发育,特大粒间孔隙增加;中粗砂岩孔径和喉道增加,而粉细砂岩孔径和喉道减小;对于河道砂体,储层的孔、渗物性变好,泥质质量分数降低,颗粒中值变小;储层的润湿性向亲水方向发展;室内实验结果显示,注水后岩心样品的孔隙度和渗透率都有一定程度增加。认识上述变化规律,对油田开发后期制定生产措施具有很好的指导作用。

关 键 词:检查井  储层参数变化  水驱  孔喉  润湿性

Abstract:In order to explore the microscopic change laws of reservoir both before and after waterflooding to guide the oilfield production and development, the reservoir parameters are analyzed on the basis of core data of early exploratory well and inspection well in the middle and later stages of oilfield development. The theory of reservoir geology and development geology is used to study the change laws of reservoir parameters both before and after waterflooding in Gangdong Development Area. The research result indicates that the sec, ondary intergranular pores develop well and the large intergranular pores are increased. The pore diameter and throat of moderate coarse sandstone are enlarged, but the pore diameter and throat of sihstone are decreased. The porosity permeability property of reservoir is improved, shale content is decreased and median grain diameter is decreased for channel sand. The reservoir wettability is changed towards water wetting. Laboratory experiment study shows that the porosity and permeability of core sample are improved to a certain extent after flooding. The study results are helpful for the establishment of production measures at the later stage of oilfield development.
Keywords:inspection well  ehange of reservoir parameter  waterflooding  pore throat  wettability
