high pressure low permeability reservoir

The Cretaceous low resistivity reservoir in Junggar basin is characterized by high porosity, high permeability, low salinity of formation water, low formation pressure and low resistivity.

准噶尔盆地白垩系油气藏具有孔隙度、渗透率高，地层水矿化度、压力系数和电阻率低等低电阻率油气藏的基本特征。

In Kuche area, the sandstone reservoir is characterized by low porosity, low permeability and high pressure, and pore texture is complex, so, it is very difficult for reservoir log evaluation.

库车地区砂岩储层以高压低孔隙度低渗透率为显著特征，且储层结构复杂，给储层测井评价带来很大困难。

Swelling, cracking, dispersion, migration and plugging of clay minerals are the main factors of the reservoir damage in high-pressure low-permeability reservoirs.

粘土矿物的膨胀、破裂、分散、运移和堵塞是对高压低渗油藏储层伤害的主要因素之一。
