Single-well overload detachment device for single-machine multi-well pumping unit

Abstract

The invention provides a single-well overload detachment device for a single-machine multi-well pumping unit, which relates to oil exploitation equipment and includes: a load center shaft connected to a first power flexible rope and a load center pipe; one end of the load center pipe and the load center shaft Sleeve, the other end is connected to the second power flexible rope; the claw mechanism is set on the load center shaft to keep the load center shaft and the load center tube relatively fixed; the control outer tube is sleeved outside the load center tube for adjustment The attitude of the jaws; the control rope, one end is connected with the first dynamic flexible rope or the second dynamic flexible rope, and the other end is connected with the control outer tube, which is used to transfer the load on the first dynamic flexible rope or the second dynamic flexible rope to Control the outer tube to drive and control the outer tube to adjust the posture of the jaws. As a weak point on the power output line of the pumping unit, the device can improve the system safety of the single-unit multi-well pumping unit. The power flexible rope of a single well will automatically break away from the system after overload, and will not affect the normal operation of the system and other wells.

Description

technical field [0001] The invention relates to petroleum exploitation equipment, in particular to a single-well overload release device of a single-machine multi-well pumping unit. Background technique [0002] In recent years, oil prices have been sluggish, and the efficiency of oilfield exploitation has deteriorated year by year. There are more than 2 million pumping wells in domestic and foreign oilfields, most of which are pumping units. Due to the development of pumping units for nearly a hundred years, the energy consumption, volume and weight are large. , the pumping efficiency is low. With the technological progress of pumping multiple wells by one unit, the reciprocating pumping of multiple wells driven by a single power of the main pumping unit has become the future development direction. However, accidental failure of a single well or excessive load during pumping stoppage will affect the pumping of multiple wells by a single unit. normal operation of the machin...

[0002] In recent years, oil prices have been sluggish, and the benefits of oilfield exploitation have deteriorated year by year. There are more than 2 million pumping wells in domestic and foreign oilfields, most of which are pumped by pumping units. Due to the development of nearly a hundred years, pumping units have high energy consumption, large volume and heavy weight. , low oil pumping efficiency

With the technical progress of pumping multiple wells with one pumping unit, it will become the future development direction for the pumping unit to drive multiple wells reciprocatingly pumping oil with a single power. normal operation of machine systems and other wells
