油气层录井的精细解释方法--以吉林探区为例

采用“四大参数法” (峰值、峰基比、甲烷和重烃) 、全烃曲线形态法和全烃储层灌满系数法, 解决了吉林探区油气层气测低异常和组分发育不全等问题。进一步以地化录井为核心, 结合核磁孔隙度和色谱油性, 建立了地化含油饱和度储层评价体系, 解决了油气层荧光、气测显示异常和电测低电阻的油层评价难题。

Precise logging interpretation methods for oil and gas layer in Jilin prospecting area

Four-parameters method, morphologic method of total hydrocarbon curves and coefficient method of reservoir thickness of total hydrocarbon were used to solve the problems of gas logging low in abnormallity and in-complete in components in Jilin prospecting area. The author established reservoir evaluation method with oil saturation by geochemical logging, NMR porosity and chromatographic oiliness, and solved the difficult problems in evaluation on low permeability and resistivity reservoirs.
