乌南油田低阻油气层成因分析及识别研究

Genetic Analysis and Identification of Low Resistivity Reservoirs in Wunan Oilfield

随着油气勘探水平的提高,非常规油气藏不断被发现,低阻油层的储量和产量都在不断增加。结合岩心及地层水资料,分析了乌南油田低阻油气层的主要成因,并提出了一种PNN(脉冲中子-中子)测井技术和常规侧向-感应测井技术相结合的低阻油层综合识别方法,从而提高了乌南油田低阻油气层的解释符合率。

With the improvement of petroleum exploration,abnormal reservoirs have been discovered constantly,petroleum reserves and petroleum production have also grown constantly.The major genesis of low resistivity reservoirs were analyzed based on the data of core and formation water in Wunan Oilfield.A comprehensive identification method combined with PNN log and conventional induction-laterolog is proposed.With this method,the interpretation coincidence ratio of the low-resistivity reservoirs is improved.
