The cyclic water-flooding method is effective for development of oil in low-permeability matrix of limestone reservoir and unsuitable for the oil-wet reservoir.
周期注水是开发灰岩储层低渗透基质中原油的一种有效方法,但对于亲油储层效果较差。
The conclusion is: capillary force is in first, elastic force is in second, water-wet oil reservoir is more suitable to cyclic water injection.
结论是,毛管力的作用是第一位的,弹性力的作用是第二位的,水湿油层更适合周期注水。
