对鄂尔多斯盆地北部苏格里气田的气藏储层进行了自生伊利石~(40)Ar/~(39)Ar法定年的实验研究.实验解决了黏土矿物的提纯、核照射反冲丢失、自生伊利石的判识等方面的技术问题,获得了自生伊利石生长年龄.通过自生伊利石的生长年龄推断气藏的形成时间晚于169Ma.
Authigenic illite ~ (40) Ar / ~ (39) Ar dating of gas reservoirs in the northern part of the Ordos Basin has been studied experimentally to solve the problems of purification of clay minerals, loss of nuclear irradiation recoil, Illite and other aspects of the technical aspects of access to obtain the age of self-generated illite growth of the age of self-generated illite inferred gas reservoir formation time later than 169Ma.
