摘要:
针对南海东部P油田投产初期高部位井产量递减快、区域能量供给不足的问题,在油藏整体能量评价的基础上,采用动态分析法和油藏数模法分区评价能量供给状况并确定天然能量开发界限,最终确定油藏边部依靠天然能量开发和中高部位注水开发相结合的开发调整策略,并优化采用中部位环状切割注水辅以高部位点状注水的注水方式。油田后续实施2口注水井和3口调整井,取得明显的注水增能提产效果。能量分区评价思路、开发调整策略和注水方式对同类型含油面积大的低流度稠油油藏的开发具有借鉴意义。
Abstract:
Aiming at the problems of rapid decline in production and insufficient regional energy supply of high part wells of the P Oilfield in the eastern South China Sea at the early stage of production,based on the overall energy evaluation of the reservoir,dynamic analysis and reservoir numerical simulation methods were used to evaluate energy supply status and determine the boundary of natural energy development.Finally,a development adjustment strategy that relies on natural energy development at the edge of the reservoir and water injection development in the middle and high parts was determined,and the water injection mode was optimized,which was circular cutting water injection in the middle part and supplemented by point water injection in the high part.Two water injection wells and 3 adjustment wells were subsequently implemented in the Oilfield,which achieved obvious water injection and energy-increasing effects.The energy partition evaluation ideas,development adjustment strategies and water injection methods have reference significance for the development of the same type of heavy oil reservoirs with large oil-bearing areas and low mobility.
