Abstract: Well Keshen 101 is a high temperature of 148.9℃ ,high pressure of 121.14MPa,high production of 213619m3/d,oil 126.75t/d and ultra deep gas condensate well of 6850 meters in depth. Surface technique process system relates to various specialitis and highly difficult technology. In view of the characteristic of super high temperature, high pressure and high wax content, a surface flow circuit called ′one operation one standby is presented, longdistance control, data acquisition and production management are realized, the complex problem of flow circuit is resolved, the risk and difficulty of management reduced. Field practice proves: The surface technique process of the well is safe and feasible. it is of great significance to the exploration of superdeep and superhigh pressure wells.

Key words: high temperature and high pressure, ultra deep gas condensate well, well Keshen101, surface technique, field practice
