This paper presents a method for evaluating formation damage by the use of capillary pressure data in laboratory obtained with the high pressure semipermeable-membrane.

使用高压半渗透隔板法测得的毛细管压力数据在实验室内可以系统地评价地层伤害的程度。

An extremely high-pressure formation, even if not flowing, may have wellbore stability problems.

对于极端高压地层，即使不流动，也可能存在井眼稳定性问题。

This is attributable to the preservation of a part of the primary porosity in the rocks due to the formation of high porosity pressure.

这种现象产生的原因是保持了一部分原有孔隙度，而保持孔隙度的控制因素是形成高孔隙压力。

Either way, the CO2 must be put somewhere, for which strategies include pumping it into rocky formations (such as depleted oil and gas wells) at a pressure of 100 atmospheres, or even piping it in liquid form under pressure onto the sea-floor where it is cold enough and the pressure high enough that it is hoped the material will stay there, assisted by the formation of CO2-hydrate.
