 在综合研究水平井射孔完井开发的技术经济指标因素基础上，根据资金平衡原理，建立了
底水油藏水平井射孔完井的合理水平段长度的优化模型，提出了一种确定水平井射孔完井的合理水平
段长度的计算方法。该模型求解后可得到水平井射孔的合理水平井段长度、合理经济开发时间、最优射
孔参数和水平井段位置等重要参数，为油田实际生产提供了重要的指导意义。利用该模型开发的水平井
射孔完井优化设计软件在油田中取得了较好的应用效果。

On the base of the study on the factors of both technical and
economic indices for horizontal perforated completion development
and according to the capital balance principle, an optimized model
of determining the appropriate horizontal interval length in bottomwater
reservoir is presented in this paper. And a new method for
calculating the interval length of horizontal perforated completion is
also proposed. This model can be used to define the important
parameters such as appropriate horizontal interval length,
appropriate development time,optimized perforated density and the
location of horizontal intervals. These parameters can be used to
guide the developed design in oilfield. The horizontal perforation
completion optimum design software (HP-DPOD) developed on this
model has obtained good application effectiveness.
