川西南矿区采用连续油管车带螺杆钻具的新工艺方法在自二井试施孔眼解堵,获得成功,为气田开发老井作业闯出了一条路子。自二井已经有32年的生产历史,单井累计产气已达44亿多立方米,为四川经济的发展作出了显赫贡献,前年被局命名为“功勋气井”。进入今年以来,自二井井下发生异常,生产出现很大波动。尤其到五月中旬,生产压力和水量大幅度下降,
The new method of using coiled tubing with screw rod drill in the southwestern Sichuan mining area succeeded in removing plugging from the perforated hole of the second well and made a breakthrough in the development of the old well in the gas field. Since the well has 32 years of production history, single-well cumulative gas production has reached 4.4 billion cubic meters, for the economic development of Sichuan made a significant contribution to the previous year was named Bureau of meritorious service. Since entering this year, anomalies have occurred since the well No.2 and the production has fluctuated greatly. In particular, by mid-May, the pressure on production and the volume of water dropped drastically,
