Abstract

The invention provides a non-stop standby load conversion device for a single-machine multi-well pumping unit, and relates to oil exploitation equipment. The device comprises a rack, a standby load mechanism which is arranged on the rack and simulates a load through reciprocating motion of a balancing weight, a power flexible rope control mechanism which is in sliding connection with a power flexible rope of the single-machine multi-well pumping unit and makes contact with a limiting block fixed to the power flexible rope to stop the sliding connection state after the power flexible rope loses the well mouth load, and a load conversion mechanism which is connected with the power flexible rope control mechanism and the standby load mechanism and drives the power flexible rope control mechanism to be hung to the standby load mechanism for enabling the power flexible rope to drive the balancing weight to do reciprocating motion after the power flexible rope loses the well mouth load. The problems that normal work of a system is affected and the running time rate is affected due to pumping stop caused by single well faults are solved.

Description

technical field [0001] The invention relates to oil exploitation equipment, in particular to a non-stop standby load conversion device for a single-machine multi-well pumping unit. Background technique [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. , the pumping efficiency and benefits are low, therefore, one pumping multi-well technology has become a new development direction, single-machine multi-well pumping unit drives multiple wells to reciprocate oil pumping through the single power of the main engine, but when a single well fails, it is easy to cause the entire single-machine The multi-well pumping unit system stops pumping, which restricts th...
