摘要
由于井壁附近地层的渗透率受到损害,形成与原地层特性不同的“表皮”区,用表皮系数S表示,S值大小一般由试井分析得到。但求得的S是一总量,它是多个因素作用的综合反映。利用公式对总表皮系数进行了分解,并利用分解出的表皮系数对钻井泥浆密度进行了分析,可以得到真实的表皮系数,在雅克拉气田实际运用中证明该方法具有一定的实际意义,可为以后的钻井及措施改造提供参数,以便进一步提高油井产量。
The integrated skin factor is decomposed by formula here and the decomposed skin factor is applied to density analysis of drilling. Then we can get real skin factor. The practice application shows this method is of a certain practical significance in Yakela gas field, which can provide parameters in later drilling and measure modifications in order to further increase well production.
