摘　　要：以正确认识镇北地区长3低电阻率油层的成因机理目的,利用该区地质资料、岩性沉积资料、岩性薄片分析资料及测井解释成果分析资料,对该区延长组低电阻率油层的成因进行较详细的剖析,得出：沉积韵律对低电阻率油层的影响、储层填隙物中特殊矿物对低电阻率油层的影响是该区长3低电阻率油层的主要成因。In order to know the low resistivity oil layer formation mechanism in Chang 3 Zhenbei area well, some data of this area are used, such as geological data, lithology sedimentation data, lithology thin section analysis data and well logging interpretation result analysis data. It is given out that sedimentary rhythm and the special minerals in reservoir fillings are the main cause of formation of low resistivity oil layer in this area.
