tight gas 是一种什么气，谁能具体解释一下？

致密气藏气

储存于致密储层的天然气，是非常规气的一种

据我 所知，在页岩气开采中，有一种气是吸附在页岩颗粒上的，需要降低表面张力才能获取气体。这种气体叫tight gas

这个一般是指致密砂岩气

致密气 非致密砂岩气

想这样的气藏开采，怎么降低表面张力，释放吸附气？

致密砂岩气，全称是tight-sand gas

Tight gas is the term commonly used to refer to low-permeability reservoirs that produce mainly dry natural gas. Many of the low-permeability reservoirs developed in the past are sandstone, but significant quantities of gas also are produced from low-permeability carbonates, shales, and coal seams.
