Recently, the new vertical drilling system technology of the American Baker Hughes Company was successfully applied in the Dawan 1 well of the key exploration well in the northeastern Sichuan Basin, which solved the problem that the well inclination was difficult to control due to the large dip angle of the formation, and the mechanical drilling speed increased by 3 times.
Well Dawan 1 is the first key exploration well deployed by the company on the Dawan structure in northeastern Sichuan, with a designed well depth of 5995m. From the well depth of 1704 ~ 1794m, the inclination increased from 3 degrees to 45 degrees. In order to control the well deviation, with the support of the relevant departments of Sinopec Headquarters, the Southern Company organized the construction unit to use the vertical drilling technology of the American Baker Hughes Company to drill from the 1829.96m well section. By February 16, it drilled to the well depth of 2444m. The meter has a total footage of 555.04m, the well inclination is reduced to 0.3 degrees, and the average mechanical drilling speed is increased to 1.94m per hour. At present, the well is deeper than 2700m.
