The full-automatic intelligent hydraulic workover rig is suitable for the development requirements of intelligence of workover operation of an oilfield and automation of whole-process operation.

Description

technical field [0001] The invention relates to a fully automatic intelligent hydraulic workover rig, specifically a kind of equipment that intelligently adjusts the automatic speed of workover operations according to the weight of the hoisting tubing string, and can realize automatic pipe transfer and arrangement at the same time, belonging to the technical field of petroleum equipment . Background technique [0002] In traditional oil field workover operations, the hydraulic energy storage workover rig used, especially when lifting the tubing string, the two motors are always in the full displacement working state, resulting in a great waste of electric energy, and An important issue is that on-site workover operations in the oil field require several workers to perform pipe arrangement, pipe transfer and wellhead operations. The work of pipe arrangement, pipe transfer and wellhead operations is not only a harsh working environment, but also has a high risk factor. In resp...

[0002] In traditional oil field workover operations, the hydraulic energy storage workover rig used, especially when lifting the tubing string, the two motors are always in the full displacement working state, resulting in a great waste of electric energy, and An important issue is that on-site workover operations in the oil field require several workers to perform pipe arrangement, pipe transfer and wellhead operations. The work of pipe arrangement, pipe transfer and wellhead operations is not only a harsh working environment, but also has a high risk factor. In response to the national "China To meet the requirements of "manufacturing 2025" and modern oilfield operations, a fully automatic intelligent hydraulic workover rig has been developed, which uses dynamic load following control technology to realize intelligent matching of energy and full automatic control of workover operations
