摘　　要：哥伦比亚达莱纳盆地V油田砂泥岩频繁交互、含油井段长、层系多、油水关系复杂,主要含油层系T组、G组地层测井资料不全,解释难度大。为了对V油田建立储层参数模型、进行系统的油藏数值模拟、对油田的进一步开发潜力做准确预测,采用分测井系列细分层系的储层参数测井解释方法,以取心井资料为基础,建立了分测井系列细分层系的储层精细解释模型;研究了岩心孔隙度与密度、自然电位幅度差、自然伽玛之间的关系;建立了各层系孔隙度、渗透率优选模型;根据建立的孔隙度、渗透率模型,对测井资料进行处理解释,求取了该油田储层孔隙度、渗透率值。The V field is a mature oilfield with multi-target stratum and sandstone-mndstone interbedding. The lack of porosity logging data in most wells is its typical feature. Because sedimentary environment, lithology and petrophysical property are different in different formation, the method of establishing reservoir parameter interpretation models for different logging suit and different formation is viable. According to core analysis data, the relationship of core porosity with density, spontaneous potential amplitude difference and gamma are studied respectively on the basis of logging data preprocess, and the relationship of core porosity with core permeability for each zone are also studied. Based on porosity and permeability interpretation model of each zone, the reservoir parameters of each zone are calculated accurately for every well in the V field. It lays the foundation for quantitative researches on reservoir geology and reservoir adjustment plan.
