松辽盆地南部深部含气性预测研究

A study on the deep gas-bearing prediction in the southern part o f the Songliao Basin

预测松辽盆地南部深部的含油气层,应采用"两部分离法",首先根据测井响应特征,对地震资料进行自然伽马、电阻率、中子孔隙度、密度及波阻抗等属性体反演,确定出地层中的砂岩层,然后,针对这些砂岩层,利用声波测井和中子测井合成ACNL曲线等,并与GR曲线交汇的油气水层识别等技术,准确地识别出含油气砂岩层。

To predict the deep oil and gas reservoir in the southern part of the Songliao B asin, we should use 'two step method'. At first, on the basis of the logging respon se characteristic, we can inverse natural gamma ray, electrical resistivity, neu tron porosity, density, wave impedance and so on, and definite sandstone layers in the strata, and then, in accordance with the sandstone layers, using oil-ga s-water distinguish technology by ACNL curves of the sound logging and neutr on logging and interlaced GR curves can accurately distmguish oil-gas bearing sa ndstone layers.
