低电阻率油层在濮城油田的认识与应用研究

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。

The Analyses and Application of Low Resistivity Reservoirs in Pucheng Oilfield

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.
