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.
间歇自喷由缓慢、稳定排油地层的低地层压力和低渗透率所致。
Intermittent flow is caused by low reservoir pressure and permeability in slowly but steadily draining formation.
地层原始渗透率越低，地层渗透率降低程度越大；
The higher the salinity and lower the initial formation permeability, the greater the permeability reduction.
地层原始渗透率越低，地层渗透率降低程度越大；
