前言为了进一步合理的开发川中油区,就需要对油层储油性质进行详细的研究,而油层渗透率就是要确定储油层性质的主要参数之一。从川中油区的喷油情况来看,数量是很大的,个别井日产量已达180吨。这一方面说明川中油区地下储油丰富,同时也表明油层的渗透率良好。但在实验室测定结果,从井中取出的岩心渗透率的数值又非常之少,一般在一个千分达西以下,因而对川中油区的储油性质就存在着分歧的意见;有人认为是地层孔隙储油;有人认为是地层层间裂隙储油;也有人认为
Preface In order to further develop the Central Sichuan oil region, it is necessary to conduct a detailed study on the oil reservoir properties, and the reservoir permeability is one of the main parameters to determine the nature of the reservoir. From the oil in Central Sichuan oil situation, the number is very large, individual wells have reached 180 tons per day. On the one hand, this shows that the oil reserves in the central Sichuan Basin are abundant, and it also shows that the permeability of the reservoir is good. However, in laboratory measurements, the permeability of cores removed from the wells is very small, generally below a thousandths of a meter, so there is disagreement on the nature of the oil in the central Sichuan Basin. Some people think that the formation Pore storage oil; some think it is stratigraphic reservoir between fractures; others think
