摘　　要：针对海上特低幅稠油底水油藏开发难度大的问题,以渤海湾Z油田低幅稠油底水油藏的开发为例,运用数值模拟法和公式法研究了可布井油柱高度下限值、隔夹层产状的影响、调整井水平段的最优长度以及投产后的生产压差控制,得出了一整套海上特低幅稠油油藏的开发生产策略。渤海湾Z油田的开发实践表明,该策略适合海上低幅稠油底水油藏的开发特点,可以在海上油田的开发中获得良好的经济效益,具有一定的推广价值。Offshore heavy oil reservoirs with bottom water in low relief structure are difficult to develop.The Z oilfield in Bohai Bay was taken as an example to study the lower limit of drillable oil column,the influence of interbed occurrence,the optimal length of horizontal section and the control on drawdown pressure by using numerical simulation and formula method,thus obtained a full suite of development strategies for offshore heavy oil reservoirs in low relief structure.The development practice in the Z oilfield in Bohai Bay has demonstrated that the strategy is appropriate to such reservoirs,can achieve good economic benefit and is worth of popularization.
