注水开发对砾岩储层参数变化规律实验研究

Experimental study on the variation law of parameters of Conglomerate Reservoir by Water Injection Development

为研究砾岩油藏水驱开发储层物性变化规律,本文以克拉玛依油田六中区下克拉玛依组砾岩油藏为目标,利用多口密闭取心井的测井、生产动态、岩心分析等资料,结合油田生产实际,研究了长期注水对储集层物性、孔隙结构以及润湿性等的影响。结果表明,经长期水洗后,储层中各种参数出现了相应的变化,具有一定的变化规律。该研究成果对油田高含水期剩余油挖潜和注采结构调整的措施制定有一定的指导意义。

In order to study the change rule of reservoir physical properties in water drive development of conglomerate reservoir,this paper takes the lower Karamay Formation conglomerate reservoir in the sixth central area of Karamay Oilfield as the target,uses the logging,production performance,core analysis and other data of multiple sealed coring wells,and combines the actual production of the oilfield to study the impact of long-term water injection on reservoir physical properties,pore structure and wettability.The research results have certain guiding significance for the formulation of measures to tap the potential of remaining oil and adjust the injection-production structure in the high water-cut period of the oilfield.
