Embodiment 1

[0013] The car body system of the present invention is composed of a tractor 1 and a trailer 2. The length, width and height of the work vehicle should meet the requirements of the special vehicle road transportation standard and meet the requirements of on-site operation. All components and operation systems are installed on the work platform 3 to facilitate transportation and operation. The work platform 3 can be connected with the trailer 2 through the slot, so that it has only one degree of freedom up and down, so as to prevent slipping during transportation. There are six hydraulic support feet on the work platform 3, the work platform 3 is supported during operation, and the trailer 2 can be driven away. When the ground conditions at the wellhead are complicated, such as a large raised platform at the wellhead, the trailer 2 cannot deliver the operation platform 3 to the position at one time, and the trailer 2 can be separated from the operation platform 3 first, and the...

Abstract

The invention discloses an integrated high-temperature pressure balance workover rig which has the advantages of being high in integrity and work efficiency and convenient to operate. The integrated high-temperature pressure balance workover rig comprises a traction vehicle, a trailer, a work platform, a derrick translation system, a framewok type derrick system, a forced lifting system, a hydraulic system, manipulator systems and the like. The work platform is arranged on the trailer, a control chamber and a hydraulic work station are sequentially arranged on the front portion of the work platform, the derrick translation system is arranged on the tail portion of the work platform, the framework type derrick system provided with an anti-blowout system and bases is hinged to the tail portion of the work platform, one end of each of two derrick turning oil cylinders is arranged on the framework type derrick system, the other end of each of the two derrick turning oil cylinders is installed on the work platform, the forced lifting system provided with a guide supporting frame on the upper portion is arranged on the framework type derrick system, and the two sets of the manipulators are connected with the framework type derrick system and the work platform respectively. All the systems are integrated on a vehicle body system, devices are convenient to transport and use, work cost is low, auxiliary work time is little, and the safety degree is high.

Description

technical field [0001] The invention relates to the technical field of oilfield workover equipment manufacturing, specifically, it is an integrated high-temperature snubbing workover device. Background technique [0002] Steam flooding injection high-temperature snubbing operation technology is an important production stimulation operation technology in deep heavy oil production technology. Yield is of great significance for the compound recovery of heavy oil, measures to increase oil production and the realization of production increase goals, and has been highly valued by the oil extraction industry. After long-term steam injection in steam flooding injection wells, it is inevitable to replace the pipe string due to pipe string deformation, seal failure and other reasons. If the conventional well killing method is used for workover operations, the existing downhole temperature field and pressure field will be destroyed, the oil layer will be polluted, the heat energ...
