樊庄煤层气区块井网调整的实践及认识

Practice and Recognition on Well Pattern Adjustment in Fanzhuang Block

樊庄煤层气区块是华北油田最早开发的区块，由于初期基础资料少，对地质、开发认识不深入，造成建产时主、分支下倾的水平井较多，直井井网配置关系较差。2010～2011年间的井网调整工作，对于区块开发形势的改善起到了积极作用。通过分析调整井生产状况，评价井网调整方式及效果，认识到井网调整有if,0于樊庄区块产量持续上升。井网调整对于促进煤层气井形成井间干扰，改善煤层气藏的开发效果具有较好作用。

Fanzhuang block is the earliest development block of Huabei Oilfield Company. Because of the less initial basic data, and the superficial cognition about the geology and CBM development, which caused that some of horizontal wells with declinate main and branch legs, well pattern configuration rela- tions of vertical wells is bad for gas production. Well pattern adjustment between 2010 and 2011 has played a positive role to improve the block development situation. Through the analysis and adjustment of the production status of wells, and evaluation of adjustment methods and effects of the well pattern, this paper realizes that well pattern adjustment is beneficial for production continues to rise production of Fanzhuang block. Well pattern adjustment has a good effect for promote coal - bed gas wells interference, and could improve the development results of coal zas reservoir.
