Model: Natural gas screw compressor for drainage gas extraction (negative pressure extraction), Guanruida slug flow technology application Case description: Sulige pure natural gas well in Changqing Oilfield of China National Petroleum Corporation gradually releases formation energy with the passage of time, and the wellhead pressure also decreases. Part of the wellhead pressure is balanced with the pipeline network pressure, which seriously affects natural gas production. In order to increase production, it is necessary to break the pressure balance, and the negative pressure extraction compressor came into being. It uses the vacuum suction principle generated by the operation of the Guanruida low-pressure and low-yield natural gas field extraction compressor to effectively break the pressure between the wellhead and the pipeline network pressure. Balance, and then greatly increase the production of natural gas extraction.
Application cases: Shengli Oilfield of China Petrochemical Corporation, Changqing Oilfield of China National Petroleum Corporation Model: Oilfield wellhead casing gas recovery and crude oil production increase and environmental protection and energy saving device, which has been authorized by the national patent Case description: Casing gas forces the fluid level of the oil well to drop, which reduces the effective production pressure difference and productivity of the oil well. A part of it enters the pump cavity of the oil well with the liquid flow and occupies a certain amount of space in the pump cavity, which affects the pump efficiency. In severe cases, "air lock" may occur, which makes the oil well pump unable to work and affects the normal production of the oil well. The traditional method uses venting to solve the problem of excessively high casing pressure in oil wells. The destruction of the atmospheric ozone layer by natural gas is 21 times that of CO2, which will cause serious environmental problems. The use of Guanruida casing gas screw compressors can not only fully recover natural gas, but also promote a 10-30% increase in crude oil production, and also solve environmental problems.

Application case: Model: Motor-driven biogas screw compressor Case description: Bio-fermentation to biogas is a mature process, and the use of pure biogas is limited, so the economic value is not large. If biogas is compressed and purified to produce bio-natural gas, the economic value will be greatly increased. Guanruida Biogas Screw Compressor is the key equipment for purification process, which is widely used in the purification of livestock and poultry manure biogas and plant straw biogas.
