Abstract

The invention relates to a multi-stage detection self-tightening protection system for preventing wellhead packing from leaking, which comprises a packing gland automatic tightening mechanism, a three-stage novel packing gland and a control system, the control system is respectively connected with the packing gland automatic tightening mechanism and the three-stage novel packing gland, and the control system is connected with the packing gland automatic tightening mechanism and the three-stage novel packing gland. The packing gland automatic tightening mechanism is used for automatically tightening packing according to set torque, the three-level type novel packing gland is used for preventing an oil and gas wellhead from being directly connected with the outside, and the control system is used for remotely controlling the packing gland automatic tightening mechanism and the three-level type novel packing gland to work so as to prevent the wellhead packing from leaking. Therefore, oil well mouth oil gas leakage can be firstly prevented and then treated through the pressure sudden change value and the torque adjusting amount, the environmental protection problem of oil well mouth oil gas leakage is thoroughly solved, and oil gas yield increasing and green and clean production are achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a multi-stage detection self-tightening protection system for preventing wellhead packing leakage. Background technique [0002] In the production process of rod pumps in oil and gas fields, the wellhead sealing packing is worn by the exposed rod for a long time, and the wellhead packing often leaks. Once it is found that the delay causes a large amount of leakage, which will bring great safety risks and environmental pollution problems, subsequent disposal and recovery will also affect the normal development of various tasks in the oil production area. At present, the treatment method for the leakage of the wellhead packing seal is mainly to rely on the oil production inspection personnel to conduct on-site inspections, and to fasten or replace the packing to eliminate the leakage after discovery. Since the packing leakage period of each well var...
