【摘要】 储层内结构的复杂性是影响油藏开发的关键因素之一。在油田开发的中后期 ,对储集层进行层序地层划分可以准确再现地层内部结构。对八面河油田某断块 Es4段 2砂组 1小层进行了储层内部结构分析。研究结果表明 ,该小层并非均质砂岩体 ,而是由 4个非同期沉积的滩坝相砂岩体叠合而成 ,每个单独的滩坝相砂体均具有独立的油水系统。依照这一研究结果 ,对另外一个断块上的一口已关生产井进行试生产 ,结果日产油 1 1 .8t,含水仅 7%

【Abstract】 Structural complexity within the reservoir is one of the major factors of influencing reservoir development During the medium later period of oilfield development,the internal reservoir structure would be represented accurately by classifying the sequence stratigraphy An analysis is conducted on the internal reservoir structure of 2 1 member of Es 4 in Bamianhe oilfield The result of study shows that the member is superimposed with 4 beach sandbodies of noncontemporaneous deposit rather than a heterogeneous sandbody Each sandbody has an individual oil water system Based on the result,trial production is performed in a closed production well on the other fault block,of which production is up to 11 8 t/d,while water cut is only at 7%
