以明确安塞县坪桥油区长6、长4+5油层组石油分布规律及主控制因素为目的,通过钻测井资料及生产试油资料的统计分析,对比分析各小层含油面积、油层钻遇率、油井系数及石油平面分布特征,结果显示研究区长61-1小层连片分布特征最好,含油面积最大、油层钻遇率及油井系数高,长4+52小层次之。通过安塞坪桥油区长6油层组石油分布规律及控制因素的分析,认为安塞县坪桥油区长6油层组油藏主控因素为:与源岩距离、沉积微相、局部构造及上倾方向遮挡。
In order to clarify the oil distribution law and main controlling factors of Chang 6 and Chang 4 + 5 reservoir group in Pingqiao Oil Region, Ansai County, through the statistical analysis of drilling well logging data and production test oil data, the oil area, The result shows that the distribution characteristics of contiguous canopy in 61-1 canopy are the best, with the largest oil area, the ratio of oil well drilling and the oil well coefficient, the length of 4 + 52 . Based on the analysis of petroleum distribution and control factors in Chang 6 reservoir of Ansai Pingqiao Oil Region, it is considered that the main controlling factors of Chang 6 reservoir in Pingqiao Oil Region, Ansai County are: distance from source rock, sedimentary microfacies, local structure And the direction of obstruction.
