低渗透储层研究出现的许多错误认识,是由于实验手段的不正确和缺少理性的科研方法所致。低渗透储层发育一些微裂缝,但裂缝开度小,连续性差,在地下被迫闭合(地下没有张开的缝),因此,渗透率极低。低渗透储层的微裂缝与粒间孔隙相当,因此,为单一介质,而不能称作双重介质。低渗透储层的岩石高压缩性和强应力敏感是由实验的系统误差所致,根本不是岩石自身的性质。滑脱效应和启动压力梯度属于实验假象,其实并不存在。
Many of the misconceptions that have emerged in the study of low-permeability reservoirs are due to incorrect experimental methods and lack of rational scientific methods. There are some micro-fractures in the low-permeability reservoirs, but the fractures are small in opening and continuity and are forced to close underground (there is no open seam in the ground). Therefore, the permeability is very low. Microfissures in low-permeability reservoirs are comparable to intergranular pores and, therefore, are single media and can not be called dual media. The high compressibility and strong stress sensitivity of low-permeability reservoirs are caused by experimental systematic errors, which are not the properties of rocks at all. Slippage effect and start-up pressure gradient belong to the experimental illusion, in fact, does not exist.
