摘要
向稠油油藏中注入CO2具有降低原油黏度、增加流体流度、使原油膨胀和原油组分蒸发的作用,可达到提高原油产量的目的。针对三塘湖盆地马朗凹陷西北部的马北构造带上马46井区低流度稠油油藏的特点,应用油藏工程方法结合数值模拟对该油藏进行了CO2吞吐可行性研究,通过优选吞吐参数、CO2吞吐矿场试验及跟踪评价,取得了较好的效果。
CO2 huff and puff can drop oil viscosity,increase fluid mobility and make crude oil swell and oil compositions evaporate to increase oil production.Based on the characteristics of low fluid mobility reservoir in Wellblock Ma-46 in Niujuanhu and Mabei structural belts in northwestern Malang sag of Santanghu basin,combining reservoir engineering method with numerical simulation study,the feasibility of CO2 huff and puff in the reservoir is studied,the huff and puff parameters are optimized,the field test is conducted and evaluated,and good application effect is taken.
