The new oil extraction pipe string developed independently by the Dagang Oilfield Production Technology Research Institute has avoided many problems in the original pipe string. The results of the two well tests are good. The core parts of the new oil extraction pipe pump are bidirectionally connected to the oil pump and the double van der pump. Utility model patents.
At present, the conventional oil extraction pipe string in Dagang Oilfield consists of ordinary oil pump and oil drainer, but there are certain defects in the function of the pipe string. Ordinary oil pump can't carry out positive circulation and well flushing. Inspecting the pump flushing sand can only put all the original well string in order to run the sanding operation under the oil pipe. It takes time and labor. However, oil drains on the column are often opened by error due to performance and quality problems, resulting in unnecessary losses and investment in oil field production and workover operations.
To this end, the Dagang Oil Production Technology Research Institute has developed two new types of oil extraction pipe columns. A two-way pumping tubing string, whose main supporting tool is a two-way pumping pump, has a positive circulation washing function compared with the ordinary pumping tubing column, and can also deepen the original well column for positive flushing, and can realize the string. No oil skimmer installed to achieve the effect of workover oil drainage. The other type is double-van der pumping tubing. The main supporting tool is double-van der pump. Compared with ordinary pump, the pump can not only prevent sand plugging, wax plugging and air lock, but also has the advantages of large oil inlet area, positive and negative well flushing, longer pump inspection period, and improved pump efficiency.
Valves
Valves have many uses, including controlling water for irrigation irrigation, industrial uses for controlling processes, residential uses, such as on/off and pressure control to dish and clothes washers and taps in the home. Valves are also used in the military and transport sectors.
The main parts of the most usual type of valve are the body and the bonnet. These two parts form the casing that holds the fluid going through the valve.
