摘要
针对渤海BZ油田储层非均质性强,注水突进严重,运用"分散相"良好黏弹性和封堵性,开展非均相组合调驱体系性能评价研究和矿场先导试验。针对海上油田平台空间狭小特点,研制在线调驱注入设备和注入工艺,解决了常规调驱设备占地面积大的问题。结果表明:非均相组合在线调驱体系能够有效封堵水驱水流优势通道,改变液流方向,扩大驱替液波及体积,改善注水开发效果。BZ油田非均相组合在线调驱先导试验的成功对海上油田稳油控水技术的开展和调驱工艺的开发具有重要意义。
Severe injection water breakthrough occurs in Bohai BZ oilfield which has strong reservoir heterogeneity. Based on the good viscoelasticity and blocking property of ＂ dispersed phase＂,performance evaluation of heterogeneous combination displacement system and pilot test are carried out. Aiming at the limited space in offshore oilfield platform,injection equipment and injection technology of online profile control and oil displacement are developed to solve the problem of large occupied area of conventional equipment. The results indicate that the heterogeneous system can effectively block fluid advantage channels,change flow direction,increase the sweep efficiency and finally improve water flooding effectiveness. The success of online profile control oil displacement pilot test in Bohai BZ oilfield is of great significance to the development of technologies for stabilizing oil production and controlling water production in offshore oilfields
