摘要
煤层气远端对接井作为一种煤层气施工应用不久的特殊井型,展现出了良好的发展前景。远端对接井是施工一定向水平井与远端的直井在井下联通。远端对接井水平段一般采用下山方式钻进,直井作为排采井,利用水重力原理,建立流体循环,达到排水降压,气体解吸的效果,从而提高产气量。
Remote concatenate well as a special well type in coal bedmethane exploitation,have a nice prospect.Remote concatenate well means drilling a horizontal well than concatenate with a straight well.Usually remote concatenate well net horizontal section drilling downhill.Straight well as a working well,utilize water gravity principle build circulation.With water draining and decompression,it＇s easy for the gas release.
