Experiment Research of Electric Analogy for Multi-lateral Wells Considering Frictional Pressure Drop in Wellbore

摘要

A series of electric analogy experiments are designed based on the water and electricity similarity principle and frictional pressure drop in wellbore. The contribution of every branch of the multi-lateral well on oil production and the impacts of the number and the angle of branches on productivity has been studied. The results show that the productivity increases as the number and the angle of branch increases, but the increasing tendency slows down. The interference between the horizontal hole and the branch on the side with fewer branches is less than that of the other side. Experimental results provide the basis for optimizing morphology of the branch wells.
