摘要
异常高压低渗透油藏地层有较丰富的天然驱动能量和压力敏感性强等特点.通过对肯基亚克油田的盐下储层及流体性质的分析,建立了油藏地质模型和数值模型.根据模拟结果和经济评价结果,确定了该类油藏不同开发时期的合理开发方案.结果表明:异常高压特低渗透油藏开发初期应该充分依靠天然能量驱动进行衰竭式开发,基础方案适用于异常高压特低渗透油藏能量衰竭到一定程度的开发前期;转注油井5口,转注时间为2022年,构成点状注气,注气井主要位于构造的高部位,井底流压为50.00MPa,是异常高压特低渗透油藏开发后期较优的二次采油方案.
Abnormal pressure and low permeability reservoirs have abundant natural driving-energy and serious stress-dependent characteristics. This paper analyzes the under-reservoir rock and fluid characteristics in Kenjiyake Reservoir, and the reservoir geological model and the numerical model have been established. According to the results of numerical stimulation and the economic evaluation, a reasonable development plan is determined in different development periods. As a result depleted development of the natural energy driving should be used in the early stages, so the basic plan is logical; d energy development should be supplied in the later time. Gas injection plan is secondary oil recovery plan, in which 5 oil wells will be changed to the gas wells located in high tectonic and climacteric in 2022, the bottom pressure being 50.00 MPa.
