| 摘 要： | 迪北地区侏罗系阿合组属于致密裂缝性砂岩储层,沉积相类型以辫状三角洲平原为主,岩性复杂,粒度变化大,岩石骨架受多种矿物影响。利用元素俘获测井(ECS),结合常规测井资料分析岩性对储层有效性的影响,为评价储层孔隙度提供准确的骨架参数。同时,裂缝是改善该区储层渗透性的重要因素,裂缝的发育程度决定了储层的渗流能力,引入EARTH IMAGER新型油基钻井液成像测井仪,并利用岩心标定成像,有效解决了裂缝的识别问题。

| Abstract: | Jurassic Ahe Formation in the north of Dina belongs to tight fractured sandstone reservoir in which sedimentary facies are braided delta plains with complex lithology, big grain size change and rock matrix affected by a variety of minerals. This paper, using elemental capture logging (ECS), analyzes the effect of lithology on reservoir and provides accurate matrix parameters for evaluating reservoir porosity. Meanwhile, the crack is an important factor to improve reservoir permeability in this area. Fracture development determines flow capacity in the reservoir. The introduction of a new image tool used in oil-based mud named EARTH IMAGER and calibration of imaging using core effectively solves the problem of crack identification. |
