摘要: 针对鱼骨井的特点,建立了半解析产能预测模型,并编制了相应软件.该模型能用于预测任意分支井的流入剖面和井筒内及井筒周围的压力分布.现场与电模拟实验结果表明,该模型具有较高的预测精度.利用该模型对鱼骨井的分支数、分支角度影响产能的分析结果表明,分支角度大于45°后鱼骨井总产能增加不大;分支数越多,对主井筒的影响越大.在总钻井长度一定的情况下,分支数不应超过3支,鱼骨井分支在主井筒的同侧比在异侧对产量的贡献大.

Abstract: According to the characteristics of herringbone well,a semi-analytical model for production prediction was established.This model can be used to predict the inflow profile of arbitrary lateral hole and the pressure distribution inner hole and around hole.The data of field pilot and electrical simulation experiment indicate that the forecasting precision of this model is good.The effects of number and angle of lateral hole on the production of herringbone well were analyzed by this model.The result indicates that a little increase of total production of lateral holes would be gained when the lateral angle is over 45 degrees.Large number of lateral hole has a great effect on the production of main wellbore.The number of lateral hole should not be more than three under given horizontal length.The higher production can be obtained when all lateral holes are set on the same side of the main wellbore.

Key words: herringbone well, production forecast, semi-analytical model, lateral configuration, pressure distribution, electrical simulation experiment
