陆良地区茨营组流体判别标准分析

Fluid Distinguishing Criterion Analysis of Ciying Formation,Luliang Area

云南陆良盆地属于砂泥岩剖面茨营组浅层气开发区,区块开发后期常含水,因此如何有效区分气层与气水同层成为储层评价的难点。利用对其储层特征的分析以及几口开发井的归纳分析,将电阻率、补偿中子和补偿声波值在气层与气水同层中的差异作为气层与气水同层的区别,初步确立了陆良地区储层流体性质的判别标准。

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.
