邵家油田沾3块近年来受区块埋深浅、流体性质与储层物性差异大的影响,层间层内矛盾突出,水驱动用程度低(51.0%),内部调整增储工作难度大,致使区块产量低水平运行。针对层间差异大、水驱动用程度低的问题,在沾3块开展全方位的治理工作,通过进一步强化注采调整、分层完善注采井网,从地下、地面多方面入手有效提高水驱动用程度,提升区块油井产能。
In recent years, the dip in Shaojia Oilfield has been affected by the shallow depth of the block, the great difference in fluid properties and reservoir physical properties, the contradiction between the layers is prominent, the degree of water-driven use is low (51.0%), Resulting in a low level of block production. In view of the large difference between floors and the low degree of water-driven use, the Company carried out comprehensive management work in Zhan 3 and further improved the injection and production adjustment so as to improve the well pattern of injection and production stratified by layers and effectively improve water from various aspects such as underground and ground Drive level, improve the block production capacity.
