Technical field
The utility model relates to oil gas field production gas technology field, be particularly related to and utilize the compressor boost gas production, drainage system and compressor two-stage supercharging gas producing device are sprayed in the utilization that is gas gathering station field special use, make full use of the high-pressure gas well stratum energy, realization ultralow pressure gas well (≤2.0MPa) two-stage supercharging is stablized the device of gas production.
Background technology
The middle and later periods of gas field exploitation, the subject matter that faces is the steady production problem of a large amount of low-voltage and low-yield gas wells.Because the formation heterogeneity influence factor, cause the natural gas well pressure drop in same gas gathering station asynchronous: the pressure of the part natural gas well is higher, needs throttling step-down gas production to produce; And the oldish well of another part can't enter gathering system and produce continuously because pressure is lower.At present, the gas field exploitation middle and later periods is mainly adopted the oldish well of compressor boost exploitation low pressure.There is some difference because of the defeated requirement of the collection in gas field for the design parameters of compressor boost.Generally selecting the compressor design inlet pressure for use is 2.0MPa, and outlet pressure is designed to about 5.8MPa.
In the oldish well process of compressor boost exploitation low pressure, stratum energy is still constantly depleted, and the remaining problem of compressor horsepower will appear in the continuous reduction of gas well deliverability.The compressor horsepower surplus can cause compressor to adopt the single-cylinder single-acting mode of operation, is in underrun state (actual power is less than 30% of rated power) for a long time.Problems such as compressor underrun meeting extraction system insufficient lubrication, combustion chamber deposit cause compressor fault frequent.In addition, because the natural gas well pressure drop of same pressurization system is unbalanced, the pressure of part well is higher than the outlet pressure of compressor, the pressure wretched insufficiency of part well.(pressure≤2.0MPa) can not satisfy the service condition of compressor inlet pressure 2MPa to the oldish well of part ultralow pressure.And the hypertonia of part well makes the inlet pressure of compressor be further improved, and influences effective performance of compressor boost effect.
