Abstract

The invention provides a mobile hydraulic pressure test machine oil well pipe stabilizing device comprising a base beam, a bearing beam, a travelling trolley, and a control system. The base beam is fixedly connected with a frame of the hydraulic pressure test machine. A push-pull cylinder is arranged on the base beam. A lug is provided on the bearing beam. The piston rod of the push-pull cylinder is connected with the lug. One side of the bearing beam is provided with a coupling stop head. A semi-cylindrical groove matching the oil well pipe is arranged on the coupling stop head. The bottom of the bearing beam is fixedly connected with the travelling trolley. A base beam recess and a bearing beam recess are respectively provided on the middles of the base beam and the beating beam. With the device provided by the invention, a problem of oil well pipe instability caused by large axial forces is solved, and an oil well pipe axial shift problem is solved. The device has the advantages of simple structure and reasonable arrangement. With the device, coupling stop head replacement can be realized simply and rapidly. The device is safe and reliable, and is suitable for hydraulic pressure tests of oil well pipes with various diameters.

Description

technical field [0001] The invention relates to a matching equipment of a hydraulic testing machine, in particular to a mobile oil well pipe stabilizing device for a hydraulic testing machine. Background technique [0002] With the growth of industrial and agricultural production and service industry, the development of transportation industry and the improvement of people's living standards worldwide, the market demand of human society for energy such as oil and natural gas is expanding day by day. At present, the demand for oil pipes and casings in oil exploration and development, especially natural gas development, continues to expand. According to the requirements of SY / T 6194 "casing and oil pipe", petroleum oil and casing must pass the hydrostatic pressure test before leaving the factory and using. Due to the development of deep wells, ultra-deep wells, high-pressure oil wells, and natural gas wells, higher requirements are placed on the performance of oil well pipes,...
