萨北开发区二类油层三元复合驱开发方式优化研究

Study on ASP Development Method Optimization for Class Ⅱ Oil Reservoir in the North Saertu Development Area

针对萨北开发区二类油层的地质特点,为探索适合二类油层三元复合驱的井网井距、层系组合方法,优化二类油层进行三元复合驱的开发方式,从开发效果、经济效益等方面进行了详细的论证,总结出以聚驱控制程度为中心,对二类油层采取限定对象、缩小井距、细分层系的开发方式。

According to the geologic features of ClassⅡoil reservoir in North Saertu development area, this paper has made careful study on the development effect and economic profit of ASP flooding, so as to find the favorable well spacing, combination of strata series and ASP development optimization method. Finally the development methods of limiting target, decreasing well space and subdividing series of strata have been concluded for the ClassⅡoil reservoir focusing on polymer flooding control degree.
