  • Patent number: 11655695
    Abstract: Oil and gas companies worldwide strive to improve artificial lift efficiencies to minimize environmental footprint and lower operational expense. In order to lower artificial lift costs, the traditional rod pump must be replaced and improved upon. The present invention of the rodless pump and multi-sealing hydraulic sub is an optimized hydraulic pumping system that eliminates rod wear, lowers pump intake pressure, and extends the reserve life of oil and gas wells regardless of casing configuration or depth. Lowering the pump's intake pressure in an oil and gas well by using a positive displacement pump such as the present invention will allow maximum hydrocarbon reserves to be produced with minimal energy consumption to power the pump. The superior surface seals and smaller footprint of the rodless pump eliminate the possibility of surface hydrocarbon leaks, minimizing environmental impact.

  • Patent number: 11592020
    Abstract: The present disclosure provides a fracturing equipment. The fracturing equipment includes: a plunger pump, a main motor and a noise reduction device. The plunger pump is used for pressurizing liquid. The main motor is connected to the plunger pump by transmission for providing driving force to the plunger pump. The noise reduction device is constructed as a cabin structure and covers outside the main motor and isolates the main motor from the plunger pump. With the fracturing equipment according to the present disclosure, the fracturing equipment is driven by the main motor with relatively low noise during operation. The noise reduction device isolates the main motor from the outside, which can effectively reduce the noise intensity transmitted to the outside during operation, thereby achieve the effect of noise reduction. In addition, the plunger pump is isolated from the main motor by the noise reduction device, thus realizing isolation of high-pressure dangerous areas and ensuring safe operation.
