摘　　要：马井气田目前采用气田内部集中增压为主、边远井小型撬装增压为补充的互补型增压模式,其中MP53D增压机组的实际处理量为12.49万m^3/d,远小于其设计处理量(35万m^3/d),机组只能低负荷运转,运行稳定性较差;同时,部分未增压气井受管网压力制约严重,气田产量递减迅速,采输矛盾日益突出。为维持气田正常平稳生产,采用Reo软件建立了马井气田集输管网模型,并设计了11种增压开采方案进行优化模拟。研究结果表明,方案5为最佳增压开采方案,此时气田的总产量最高,增压机组消耗的功率低,机组运行稳定性好。优化后气田的总产量增加12.07万m^3/d,压缩机站总功率降低26 k W,MP53D压缩机组处理量增大6.92万m^3/d,机组运行稳定性提高。The combination boost mode of integral boost as the principal and luge remote wells was used in Majing gas field, MPS3D booster unit whose the actual processing capacity was 1. 249× 10^5 m3/d, far less than its design processing capacity of 3.5×10^5 m3/d, the unit can only be low load operation, the operation stability was poor; At the same time, some of the non pressurized gas wells were severely restricted by the pressure of the pipe network, and the production of the gas field was decreasing rapidly. The contradiction between production and transportation became increasingly prominent. In order to maintain the normal production of gas field, the Reo software was used to establish the model of the gas gathering and transportation pipeline network in Majing gas field, And 11 kinds of pressurization mining plan were designed to carry on the optimized simulation. The research results show that the scheme 5 is the best boost mining scheme, the total output of the gas field is the highest, the power consumption of the booster unit is low and the booster unit runs more stable. After optimization, the total output of the gas field is increased by 1. 207×10^5 m3/d, the total power of compressor station is reduced by 26 kW, and the processing capacity of MP53D compressor is increased by 6.92× 10^4 m3/d, and the operation stability of the unit is improved.
