摘　　要：表皮系数在油藏工程中是一个极为重要的技术参数。通常它是由矿场试井方法求得,但试井解释的表皮系数是一个总的表皮系数,它包括钻井、固井以及完井过程中一切引起偏离理想条件的各种拟表皮系数的总和,并不是真正储层污染特征的表现。本文应用了表皮系数系统分解方法的研究成果,编制了相应的软件,在辽河油田试算应用,对试井解释的总表皮系数进行了系统分解,求得了各项分表皮系数以及真实表皮系数。实例和现场服务证明是可行和有效的,因而,为真正评价钻井、完井、试采、储层保护技术和油层改造措施提供了可靠的依据。Skin factor is a very important technical parameter in the reservior engineering. It is alwags calculated and abtained from well testing in the field, but the skin factor of well testing interpretation is a total skin factor,it includes sum total of verious imitable skin factors away from ideal condition resulted in drilling,cementing and completion, and it is not the display of real characteristic of reservior damage. The paper used the study results of the method for solving skin factor systematically, corresponding software wan made, and was used in Liao lie Oil Field,the general skin factor of well testing interpretation was resolved systematically and every branch skin factor and the real skin factor were abtained. It is available and effective that certified with case and field service, therefor, a reliable basis for the techniques of really evaluating drilling,completion,testing and producing and reservior protection and the oil formation remaking measure were given.
