Fluid Distinguishing Criterion Analysis of Ciying Formation,Luliang Area
Luliang Basin of Yun’ nan belongs to a sand-shale shallow gas developing area, with water in the later period of block development. Therefore, how to distinguish efficiently the gas zone and gas-water zone becomes a difficulty of reservoir evaluation. Analyzing reservoir characteristics and some developed wells, comparing the differences of resistivity, compensated neutron and compensated sonic value in gas zone and gas-water zone, this paper establishes the distinguishing criterion of reservoir fluid property in Luliang area.
