煤层气多分支水平井井眼轨道优化设计模型
Trajectory optimization design model of multi-branch horizontal well of coalbed methane
摘要
Abstract
Coal reservoirs have features of low pressure and low permeability, making exploitation difficult and-well yieldlow. However, multi-branch horizontal well may increase the contact area with the coal, enhance produc-tion and shorten the economic recovery period. Hence well trajectory optimization criterion of coalbed methane (CBM) multi-branch horizontal well is presented in this paper. In addition, authors established a trajectory optimal design model of the sidetrack horizontal well and then used sequential quadratic programming method (SQP). Fi-nally well trajectory is planed by this model based on geological data in Zhengzhuang of Shanxi Province. The re-sults show that the model achieves optimization design of multi-branch horizontal wells of CBM and deserve somewhat consideration for guideline in the process of well design.关键词
