he top-driving casing device is a new type of equipment that directly clamps and rotates the casing string for casing operation by using a top-drive drilling system. It is produced by Beijing Petroleum Machinery Plant and is suitable for casings of casings of different specifications and wall thicknesses. Tube operation. This device can be used instead of conventional casing pliers to perform turn-on buckle. It can rotate or lift the casing string at any time when it encounters complex situations, and can inject and circulate drilling fluid at any time. Potential safety hazards and many downhole risks. This technology has been widely used in foreign countries, especially in North America, but it is still blank in China.

In order to ensure the smooth running of the casing test, the company held a special meeting with the technical staff of the drilling company and the North Stone Plant before the operation, repeated discussions on the test details, and drafted two plans. During the operation, the three parties actively cooperated and cooperated with each other, the casing rotation process was stable, the upper torque control was accurate, the operation process was safe, and the field test was successful at one time.

The success of this experiment will strongly promote the mechanization and automation of casing operation technology and equipment, which will add another new weapon for the company to strengthen and expand its technical service business and increase market competitiveness.
