萨北油田北二东两三结合试验区高台子油层储层非均质性

本文在沉积微相基础上进一步对储层层内、层间、平面的非均质性及对开发的影响进行了研究。结果表明:大庆油田北二区东两三结合试验区高台子油层层内及层间属中等—弱非均质性,平面上储层非均质性较严重,属中等非均质性。通过对此类储集层非均质性系统研究,对于正确认识和评价油气藏,合理部署井网、划分开发层系、制定合理的三采调整方案,提高开发效益都有重要意义,同时也对相似情况储层非均质性的研究具有借鉴意义。

Reservoir Heterogeneity of Gaotaizi Oil Layer in the Two Tertiary Combined Experimental District of the Second Eastern Region in the North of Sabei Oil Field

The heterogeneity of the inner layer,the interlayer,the plane of the reservoir and the influence to the development was studied based on sedimentary microfacies.The result shows that: the inner layer and the interlayer heterogeneity of the Gaotaizi oil layer are medium-weak,the plane heterogeneity of the reservoir is severe.It can be classified into medium heterogeneity in the two tertiary combined experimental district of the second eastern region in the north of Sabei Oil Field.Through systemic research on heterogeneity of this kind of reservoir is very useful for understanding and evaluating oil and gas pool correctly,designing reasonably well pattern,compartmentalizing development zones,making suitable plan for enhancing recovery,improving the efficiency of oil recovery.And it also can be a reference for similar research of reservoir heterogeneity.
