摘要
定向羽状水平井技术是近几年兴起的一项煤层气地面抽采技术。大宁矿区作为我国煤层气羽状水平井开采的一个试验区块打了第一口DNP02羽状水平井。本文首先对定向羽状水平井的数值模拟技术进行简单的介绍,然后结合该地区的实际地质情况对试验井DNP02进行了产能预测,为以后煤层气开发方案设计和经济评价提供参考。
The directional pinnate horizontal multilateral well has been a rising technology in recent years for increasing eoalbed methane recovery. Its application is still in the test stage in China. China drilled the first pinnate horizontal multilateral well DNP02 in Daning test area. The numerical simulation technology of the directional pinnate horizontal multilateral well is introduced briefly. Based on the geological conditions in Darting test area, the production capacity of the test well DNP02 is predicted, which will be used for the scheme design and economic evaluation in eoalbed methane development.
