为研究鱼骨状分支井相关参数对产能的影响并检验李春兰鱼骨型水平井产能计算公式的适用性，开展了鱼骨状分支井电模拟实验，实验结果表明：鱼骨状分支井分支位置、分支长度、分支数、分支夹角以及分支分布方式等因素对产能均有影响，其中，分支位于两端时的产能大于分支位于中部时的产能；产能随着分支长度、分支数和分支夹角的增加而增大，增大趋势逐渐减弱；分支均匀分布与对称分布的产能接近，同侧分布产能则低于前面两种情况，且分支越长，产能差异越大。通过正交实验评价各参数对产能影响的显著程度顺序为：分支数>分支长度>分布方式>分支夹角；当分支均匀分布时，李春兰2005年公式精度要高一些，而分支对称分布和同侧分布时，李春兰2010年公式精度更高。实验结果为鱼骨状分支井的优化设计以及注采井网的研究提供了依据。

Conducted is electric simulation experiment on herringbone multilateral wells in order to research the effect of related parameters on well productivity and to test the applicability of the productivity calculation formula used for Li Chuanlan herringbone horizontal wells and the experimental results show that such factors have effect on well productivity as position, length, quantity, angle and distribution mode of branches. The productivity in case of branches lying in both sides of a well is higher than that in case of a branch lying between two wells, productivity index will increase along with increase of length, quantity and angle of branches and the increase will drop off, the productivity index in case of branches being uniformly distributed is close to that in case of branches being symmetrically distributed, the productivity index in case of branches lying in the same side is lower that those of the first two cases and the longer the branches, the larger the productivity index difference is. The sensitivity of each factor is evaluated by orthogonal design. The parameters affecting the productivity of herringbone wells are as follows: quantity>length>distribution pattern>angle. Under the uniform distribution, Li Chunlan (2005) formula has higher precision and Li Chunlan (2010) formula is more accurate in case of symmetric and the same side distribution. The experimental results can provide the basis for optimization design of herringbone branch wells and injection-production pattern.
