多井集气 井场只有采气树，气体经初步降压后送到集气站，汇集多口 （≤10） 气井的气体，分别对各井气体节流调压，然后集中进行分离、 计量和预处理，再经集气管网到总站，外输至处理厂。 In the well site, only the gas trees are available, and the gas is sent to the gathering station after the initial pressure lowering, gathering the gas of multiple (no more than 10) gas Wells, and the gas is throttled and adjusted for pressure in each well, and then separated, measured and pretreated in a concentrated way, and then transported to the main station through the collecting gas pipe network, and then transported to the treatment plant.
