摘要
本文通过模拟计算的方法,得到钻井液所产生的污染半径,结合污染半径及钻井液漏失量对目标井进行施工设计,确认合理的施工时间,获取更准确的地层参数,并建议低压煤储层的注入/压降试井应尽量在套管中长时间测试。
In this paper, the pollution radius of drilling fluid is obtained by the method of simulation parameters. It is suggested that the injection/fall test of the low pressure coal reservoir should be long time tested in the casing.
