多分支井电模拟实验研究

以水电相似原理为基础,针对对称式多分支井和任意夹角的双分支井进行了一系列电模拟实验。评价了对称分支井的产能公式,重点研究了分支角度对分支井产能的影响;提出了分支增产系数的概念,运用建立的分支增产系数公式计算了各种夹角的双分支井产能随夹角的变化并进行了实验验证。为优化分支井的结构和建立分支井的半解析产能模型提供了依据。

Experimental Research on Multi-lateral Wells by the Electric Field Analogue Model

There is a close theoretical similarity between water pressure gradients in aquifers and applied voltage gradients in aqueous solutions. A series of electric field analogue experiments has been conducted by focusing on symmetrical multi-lateral wells and dual-lateral wells of arbitrary angles between laterals. This research not only evaluates the productivity equations of a symmetrical multi-lateral well showing the effect of angles on productivity, but also proposes the concept of the multi-lateral productivity coefficient. Moreover, the multi-lateral productivity coefficient equation is designed to calculate the productivity of dual-lateral wells of variable angles, which is in turn supported by experiment. It also helps provide the experimental basis for optimizing the configuration, and building the semi-analytic productivity model, of multi-lateral wells.
