coefficient of percolation
1.During Eocene the correlative coefficient of percolation was still high(about 0.2 m/d~3.6 m/d) in Jinding area. This had caused the low fluid potential area lying between the two high fluid potential areas and the current velocity was about 22.33 mm/a~34.16 mm/a.
2.Well Yeyun2 was a new exploration well at front hill confirmation in Tarim oilfield sub-company in 2004 which depth is 6230 meters, formation pressure coefficient is 2.0 and temperature is 150℃. For geology breakthrough and according to feature of HP-HT and super-low percolation, some new testing tech of combining perforation, hydraulic adding sand fracture, bore hole interpretation and multiple grades outflow fluid have been utilized to reform reservoir, and for acquired testing data, deepen acquaintanceship has been gained.
