在储层岩性细、粘土矿物多、微孔隙多、颗粒亲水等原因上分析了低电阻率油层成因机理。对濮城油田多种成因类型的低电阻率油层进行了地质成因分析,并具体划分为粘土矿物成因型、岩性成因型、复合成因型。根据岩性分析图版,结合其它影响因素,得出了濮城油田多成因低电阻率油层的解释方法及规律,将这一规律应用于实践中,取得了显著的效果。

Based on the layers are more with small lithological substances , clay particles , millipores and hydrophilic substances , the paper analyze the origins of low resistivity reservoirs. Through the analyses of geologic origins of low resistivity reservoirs with multiple origins in Pucheng Oilfield , the origins are divided into three kinds , they are mineral formation , lithology formation and composite formation. In the actual interpretation ,according to lithologic chart , combined with the other influence factors , the interpretation regulations of low resistivity reservoirs with multiple origins are obtained in Pucheng Oilfield. After the regulations used in practice , obvious effectiveness are obtained.
