摘要:
定量描述组合井网中水平井的作用及组合井网井间动用规律,是组合井网高效部署和油田高效开发的关键.基于实际油田组合井网形式,建立反映实际井网特点的渗流模型;利用保角变换,求解得到确定井网条件下的势函数与流函数;提出注采井间无因次动用范围的概念,建立定量描述组合井网井间动用规律的方法;结合油田实际计算结果对比,组合井网中水平井部署后,注采井间消耗的压力降减少;中-高速流动区范围扩大,而低速流动区范围减小;当正对直井产量比越小,这种变化趋势越明显.研究表明,基于建立的方法,可以定量研究组合井网井间动用规律,为组合井网高效部署提供技术支持.
Abstract:
It’s the key for developing oilfield and deploying composed well patterns efficiently to describe the function of horizontal well and inter-well production regularity quantitatively in composed well patterns. Based on composed well patterns in an actual oilfield,seepage model for the characteristics of actual well patterns is setup. Dimensionless range concept of production between producing and injection wells is proposed to establish the method in which the inter-well production laws can be depicted quantitatively. In comparison with the calculating results of the actual oilfield,it can be concluded that after deploying horizontal wells,the pressure drop between producing and injection wells decreases,which results in the extending of medium and high-speed flowing region and the contract of low-speed flowing region. This trend will show more apparently when the production ratio reduces. It can be drawn that inter-well production regularity can be researched quantitatively by the proposed method and can provide technical support for deploying composed well patterns efficiently.
