摘要
对樊庄区块煤层气井X1进行产能模拟并分析其产气效果,通过选取同区域、相似地质条件的若干高产井进行排采对比,得出有助于X1井产能提升的排采优化对策:合理控制套压和液面深度;适当增加排水量;分级逐次降压。
Gas capacity simulation of CBM well X1 in Fanzhuang block was firstly done. Based on the simulation result, the extraction efficiency was analyzed. Then, compared with some nearby high capacity wells which have similar geology background of X1, there may be some optimizing countermeasures good to achieve higher gas capacity. The measures contain reasonable system pressure and surface depth, a little more water quantity and bottom pressure falling step by step.
