With the increase of oilfield exploitation depth, the weight of beam pumping unit rod pipe increases, and the inertial force increases, which seriously affects oilfield production efficiency. Rodless reciprocating pump with submersible motor has fewer power conversion links and lower energy consumption low and high system efficiency. However, due to processing and assembly errors, there […]

Optimizing Energy Consumption of Electric Submersible Pump in Offshore Oilfield   Electric submersible pumps have always been highly praised for their large displacement and head for lifting oil production. In addition, the electric submersible pump production system has the advantages of simple ground equipment, convenient operation, small equipment occupation area and space, and long service […]

On the dynamic mechanism of pumping steel ball in downhole tubing  With the exploitation of unconventional oil and gas reservoirs, staged hydraulic fracturing technology has been widely used, especially in the re-fracturing of old Wells, which usually adopts the staged fracturing technology of tubing sliding sleeve. The technology consists of tubing with multiple sleeves and […]
