面河油田北一区地处山东省广饶县,构造上位于八面河鼻状断裂构造带北部,为复杂小断块边底水油藏,包括角15块、角10-斜6块、莱12块等8个小块,截止2009年底,剩余地质储量34.08万吨,采收率30.9%。经过20多年的滚动勘探开发,非主力砂体剩余地质储量94.25万吨,约占剩余地质储量的43.2%,因此,在目前的开发形式下,采取适当方法提高非主力砂体采油速度及采收率,对延缓产量总递减具有现实意义。
Bianhe Oilfield Beiyi District is located in Guangrao County, Shandong Province and is structurally located in the north of the Bamei nose-like fault tectonic belt. It is a complex small fault-edge water-margin reservoir with 15 corners, 10 angles and 6 oblique angles, And other eight small blocks, the end of 2009, the remaining geological reserves of 340,800 tons, recovery rate of 30.9%. After more than 20 years of rolling exploration and development, the remaining geological reserves of non-main sand bodies have reached 942,500 tons, accounting for 43.2% of the remaining geological reserves. Therefore, under the current development model, appropriate measures are taken to increase oil recovery rate and recovery of non-main sand bodies The rate of delaying the total output decline is of practical significance.
