延川南煤层气开发试验区井网部署与优化研究

摘要

煤层气井网优化是煤层气开发的重要环节,井网部署的合理与否,不仅关系到单井产量的大小,而且直接影响到煤层气试验区开发效果的成败。本文对井网部署原则以及优化方法进行了探讨,给出了井距优选的多种方法,并把这些方法应用于鄂尔多斯盆地延川南煤层气试验区的开发井网优化,为该区的煤层气开发方案设计提供了合理依据。%Optimization of CBM well pattern is an important link in CBM development. Whether the ar- rangement is rational or not it is not only related to the scale of a single well production, but also it affects directly the success of development in the CBM experimental zone. The paper deals with the principles of well pattern arrangement and the optimization methods. It proposes a multiple of methods for selection of well spacing. These methods have been applied to optimization of development well pattern in Yanchuan south CBM Experimental Zone in Ordos Basin. It provides rational criterion for design proposal for devel- opment of CBM in this zone.
