Its formation mechanism includes well-developed net-shaped clay in tight sandstone which fill the intergranular pores and form micropores, and water-locking effect which can enhance capillary pressure and reduce greatly the gas permeability as well so as to make it the effective caprock of gas reservoir.
英南2气藏之上非常规致密砂岩作为盖层,形成机理是致密砂岩中网状粘土发育,充填于粒间,形成大量微孔隙,水锁效应增大毛细管压力,极大地降低气体渗透率使其成为气藏有效盖层。
The thermatic fibrous sepiolites are ones of rich Magnesium,richened with Magnesium,silicon and few Aluminum,and the sedimentary clayey sepiolites are ones of rich Aluminum,have lower Magnesium,Silicon and higher Aluminum.
本文通过两种不同成因海泡石化学成分特征的研究发现，热液型海泡石和沉积型海泡石的化学组成有较大差异，热液型纤维状海泡石ＭｇＯ、ＳｉＯ２含量高，Ａｌ２Ｏ３含量低，为富镁海泡石；沉积型粘土状海泡石ＭｇＯ、ＳｉＯ２含量低，Ａｌ２Ｏ３含量高，为富铝海泡石。
