摘　　要：依据相似原理,采用电模拟试验装置,设计了辐射状分支井模型.研究了在不同分支数、分支水平段长度时,辐射状分支井井筒附近的压力分布,描述油藏中的压力场形态,评价各种参数对产能的影响,为水平井产能预测提供了依据.The experimental model of radial-distributing multi-branch horizontal wells is designed on the basis of similarity principle by means of electrical analogy.The voltage of the model is measured and the pressure distributions near the radial-distributing multi-branch horizontal well-bores are analyzed and investigated under different number and length of branch wells.The pressure results can be used for describing the pressure field in the reservoir and evaluating the effects of various parameters on the productivity of the wells.This can provide the base for the prediction of the productivity of the radial-distributing multi-branch horizontal wells.
