摘要
综合应用地震、测井、录井、岩心、铸体薄片及相关分析测试等资料,对盐家地区沙三段中浅层砂砾岩扇体油藏的成藏条件及成藏特征进行研究。研究表明:砂砾岩扇体主要为近岸水下扇和扇三角洲沉积,构造因素、成岩作用、流体性质是形成油藏侧向封堵的主控因素。根据侧向封堵条件的差异,盐家地区主要发育4种类型的油气藏,沙三中上亚段主要为流体差异封堵的岩性油藏,沙三下亚段主要为背斜构造、构造-岩性油藏和成岩差异岩性油藏。
By integral use of information derived from seismic,logging,mud logging,core,cast thin section and associated analysis and tests,the reservoir forming conditions and features of the mid-shallow Sha 3 member glulenite fan in the Yanjia oilfield are investigated.It is indicated from study that,the glutenite fan is mainly subaqueous fan and fan delta deposits;and structural factors,diagenesis and fluid property are the primary controlling factors over lateral sealing of the oil reservoir.Based on the difference of sealing conditions,four types of oil and gas reservoir were developed primarily in the Yanjia area,including mid-upper sub- member of Sha 3 formation as a lithologic oil reservoir sealed by fluid difference,and the lower sub- member as an anticlinal structure,structural- litlhologic oil reservoir and a lithologic oil reservoir occurred by diagenetic difference.
