摘要
鄂尔多斯盆地F油田长8油层储层为三角洲前缘的水下分流河道砂体,生储盖组合极佳,理论上应该有较大的成藏规模,但实际成藏规模小,油藏连续性差。经分析认为,有利的生烃条件、三角洲前缘沉积环境、局部鼻状构造和排驱压力大是控制该区长8油层组油藏分布的关键因素,是造成F油田特殊成藏规律的主要原因。
Ordos basin F oil reservoir for 8 layers of delta distributary channel sandbodies, soure-reservior-roof admirable,there should be larger in size,but in small scale,practical accumulation reservoir continuity.Through analysis,the favorable hydrocarbon generation condition,the delta front sedimentary environment and local structure and pore structure is to control the oil reservoir distribution district 8 group is the key factor that causes F oil accumulation rule of special reasons.
