2results about How to "Improve oil pumping efficiency" patented technology

The invention relates to the technical field of oil well pumps, in particular to a plunger type oil well pump for oil field exploitation. Comprising a pump cylinder, a fixed valve seat is detachably connected to the lower end of the pump cylinder, a fixed valve is placed in the fixed valve seat, a traveling valve seat is slidably connected to the interior of the pump cylinder in a sealed mode, a traveling valve is placed in the traveling valve seat, an installation cylinder is slidably connected to the interior of the traveling valve seat, and a lower positioning frame is fixedly connected to the inner side of the installation cylinder; the lower positioning frame makes contact with the lower portion of the traveling valve, and the mounting cylinder drives the traveling valve to move through the lower positioning frame. The installation cylinder actively controls the traveling valve to move and controls the traveling valve to actively relieve blocking of the traveling valve seat in the down-stroke period, so that when crude oil containing natural gas is extracted, the pressure difference needed by opening of the traveling valve seat is reduced, the invalid stroke generated due to gas compression is shortened, the effective liquid drainage stroke length of the plunger is prolonged, and the safety performance of the plunger is improved. And the fullness coefficient and the oil pumping efficiency of the pump are improved.

This invention relates to the field of petroleum equipment technology, and more particularly to a method for modifying a power distribution box for remote control of intermittent pumping operations of pumping units without shutting down. This method includes: laying signal transmission cables to connect the well RTU to the frequency converter in the power distribution box; upgrading the well RTU program according to the frequency converter's communication protocol to enable it to read and modify frequency converter parameters; achieving interconnection between the PC-based remote control system and the frequency converter to read and remotely modify frequency converter parameters; and issuing intermittent pumping commands to the frequency converter through the PC-based system according to the set intermittent pumping operation parameters to achieve remote control. This method utilizes signal transmission cables and the frequency converter's communication protocol to read and transmit frequency converter parameters in real time, ensuring accurate and reliable data. Remote control reduces frequent on-site equipment operation, allowing operators to centrally manage the intermittent pumping operations of multiple pumping units on a PC without manual on-site adjustments, thus reducing manual operation time and labor intensity.
