| 摘 要： | JR-121井位于北京市定福庄南里,开采蓟县系雾迷山组1600m以深热储层的岩溶裂隙水。该试验井施工使用GZ-2000型水源钻机,TBW-850/50型泥浆泵,钻探深度2202.98m。成井过程中,根据不同层段,采用不同成井工艺,在目的含水层的上覆非取水层段,采用分级下套管及水泥封闭的方法进行止水,泥浆与回旋方法钻进;在取水段,采用裸眼孔底钻铤加压、泥浆护壁与回旋钻进。洗井工艺上,采用酸化、液态CO2和空压机引喷相结合的联合洗井方法。使用此成井工艺,止水效果良好,达到了开发岩溶裂隙地热水的目的。

| Abstract: | The No.JR-121 well is located in Dingfuzhuang Nanli,Beijing.It mines karstic fissure water from a geothermal water reservoir under the depth of 1600m in Wumishan Formation,Jixian System.The GZ-2000 type water source drill rig and TBW-850/50 mud pump were used in the test well construction,drilling depth 2202.98m.The well completion technologies including: stepping casing in,cementing sealing up,mudding and rotary drilling were used in aquifer overlying non water drafting sector;open-hole bottom drill collar pressure drilling,mudding and rotary drilling were used in water drafting sector.Well cleanup technology of combined acidifying,liquid CO2 and air compressor blowout inducing method was used.The well completion technology has good water sealing result and helpful in the karstic fissure geothermal water exploitation. |
