Abstract
The utility model discloses an oilfield associated gas compressor which comprises a compressor body, and a plunger matched with the compressor, wherein one end of the plunger is connected with a joint body, the joint body is fixed on a walking beam of a pumping unit, and the compressor body is further provided with a gas inlet one-way valve and a gas outlet one-way valve. The compressor disclosed by the utility model mainly adopts the excess balance weight load of the pumping unit as power, the compressor is pulled and driven by the movement of the walking beam, so as to finish the processes of gas suction and compression. The compressor is driven by the power of the pumping unit, and routine potential energy of a pumping rod is adopted as energy needed by the gas compression, so that the weight of the pumping rod is balanced, the balance weight of the pumping unit is reduced, the load of the pumping unit is stabilized, and the process technical support is provided for recycling crude oil associated gas of an oilfield and saving the oil extraction cost.
Description
Technical field
The utility model relates to oil exploitation technology, is specifically related to a kind of associated gas compressor.
Background technique
Associated gas also is a kind of of natural gas resource, it is a kind of mixture, wherein often contain the very big non-hydrocarbons compounds of harmfulness such as moisture, carbon dioxide, hydrogen sulfide, nitrogen, helium, mechanical admixture, therefore, needed processing technology is more more complicated than the treatment process of general reservoir gas and condensate gas, the amount of associated gas is generally less in addition, available pressure energy is lower, often being mistaken as in the past is nugatory rock gas, adopts the method for directly burning to handle for them toward row.Global gas production in 2002 is 32500 * 10m3, and wherein 2.5%～3.0% (about 800 * 10～1000 * 10m3) are consumed in torch burning.In view of rock gas is valuable resource, World Oil Industry circle is actively making great efforts to eliminate flaring.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of associated gas compressor.
The technical solution of the utility model is: a kind of associated gas compressor, comprise compressor body, with the plunger of described compressor coupling, described plunger one end is connected with union body, described union body is fixed on the pumping unit walking beam, also is provided with suction port one-way valve and air outlet one-way valve on the described compressor body.What the suction port one-way valve connected is the oil gas mixing tube road, and what the air outlet one-way valve connected is an equipment that is similar to gas holder, and the rock gas after the compression is stored.
Further improvement of the utility model comprises:
The end that described plunger is connected with union body is provided with the travel position adjustable lever.
Described compressor is fixed on the described pumping unit shelf.
The utility model mainly relies on the unnecessary counterweight load of pumping unit as power, and the motion by oily beam comes traction drive compressor (need not motor), thereby finishes air-breathing, compression process.This appliance arrangement is with the pumping unit motivational drive, and with sucker rod backhaul potential energy as gas compression institute energy requirement, balance rod weight, reduced oil extractor balance weight, stablized pump load.Be the same receipts utilization of crude oil associated gas, save cost for oil production, the process engineering support is provided.
The utility model not only can help to realize closed gathering, and helps to improve oil output per well (reduction bottom pressure), effectively improves oil and gas multiphase flow performance (form gas-liquid whirlpool flow mixing transfusion, reduce wax deposition, fouling) and significant to reducing the oil field development cost.The utility model is simple in structure is convenient to installation and maintenance; Low maintenance and operation cost, the cost performance height; There is not special basic requirement; Compression ratio is adjustable, pressure range wide (can reach more than the 8MPa); Need not power source driving, do not have additionally power consumption; Be fit to continue or intermittent duty and various operating mode.The utility model adopts the multistage compression technology; Sealing technique; The double acting compressor technology; The three-dimensional tooling technology of optimizing.
