杜48块是曙光油田薄互层普通稠油油藏典型区块之一,地质储量1689×104t。主力油层吞吐开发后期采出程度高,挖潜余地小,而部分非主力油层由于各种因素一直未得到有效利用,在开发后期对这些油层进行二次开发,通过精细地质研究,采取有效的挖潜手段,从而能够提高区块采收率,为区块后期开发提供有利的稳产保障。
Du 48 block is one of the typical blocks of common heavy oil reservoirs with thin interbed in Shuguang Oilfield with geological reserves of 1689 × 104t. In the later stage of development, the main reservoir is high in exploitation and small in excavation potential, while some non-main reservoirs have not been effectively utilized due to various factors. Secondary development of these reservoirs is carried out in the late stage of development. By means of fine geological research, effective tapping methods , So as to improve the recovery rate of blocks and provide favorable stability and security for the post-development of blocks.
