油田递减阶段配产方法研究

目前我国大多数油田已进入开发后期,都存在不同程度的产量递减现象。对产量配产进行分析必须对产量构成有清楚的认识。本文将产量分成老井自然产量、老井增产措施产量、新井产能三个部分,引入无量纲量,针对每一部分产量进行相应的分析,这种方法完善了仅凭总产量便对油田产量进行配产的方法,更具有科学性、实用性和可操作性,在油田年度部署中能够发挥积极的作用。

The Study of Allocation Method in Oil Field Decline Period

Most of oil fields in our country were in the production tail, and they had the phenomenon of decline of production at varying degrees. It must be distinct for the composition of production when allocation. This paper separates production into there parts, old well natural production, old well stimulation treatment production and initial well deliverability, and we introduces new analytical method for each production. We used dimensionless parameter to analysis each production. This method improves allocation by total production in the past and it is more scientific, practicability, controllability than old method. This method can display active action in oil field year dispositicn.
