摘　　要：水平井开采技术是油气田开发过程中提高采收率增加产能的一项重要技术。通常水平井水平段越长,油气产量就越高。但是在实际的生产过程中,水平段长度并不是越长越好,选择合理的水平段长度是水平井开发过程中一个非常重要的问题。通过水平段长度计算模型可以计算出水平段的长度,也可通过数值模拟方法对水平段长度进行优化,同时也应考虑钻井费用从经济的角度来研究水平井段的最佳长度。Horizontal well drilling is an important technology for improving oil recovery and increasing the productivity in the process of oil and gas field development. Usually the longer the horizontal section length, the higher oil and gas production. But in the actual production process, the horizontal section needs reasonable length, so choosing the reasonable horizontal section length is a very important problem in the process of horizontal well development. The horizontal section length calculation model can calculate the horizontal section length, and can also optimize the length of the horizontal section by the numerical simulation method. At the same time, the drilling cost should be also considered from the economic point to study the optimal length of the horizontal section.
