Compared with conventional well, herringbone-like laterals wells can increase\nthe area of oil release, and can reduce the number of wellhead slots of\nplatforms, and also can greatly improve the development efficiency. Based on\nthreshold pressure gradient in heavy oil reservoir, and the applied principle of\nmirror reflection and superposition, the pressure distribution equation of\nherringbone-like laterals wells is obtained in heavy oil reservoir. Productivity\nmodel of herringbone-like laterals wells is proposed by reservoir-wellbore\nsteady seepage. The example shows that the productivity model is great accuracy\nto predict the productivity of herringbone-like laterals wells. The model\nis used to analyze the branching length, branching angle, branching symmetry,\nbranching position and spacing and their effects on productivity of herringbone-\nlike laterals wells. The principle of optimizing the well shape of herringbone-\nlike laterals wells is proposed.
