Spray Drainage Technology In Yulin Gas Field Of Applied Research

Currently there are 23 south yulin gas field in tone,2008 intermittent gas well open when 27.39% rate for gas, due to effectively control scope of small, gas well productivity, low pressure drop, well after continuous production can't. It is mainly adopts "long open" and "short short shut off and "open long long winter, summer" three production system, hard work productivity. On the analysis of the current production batch Wells in yulin gas field, based on the evaluation of the current gas technology, and put forward the existing problems, and the characteristics of gas Wells, research on the jet in yulin gas field matching technology, and drainage field retrofit installations, experimental simulation device, internal flow field of flow pattern, the device parameters of accounting. Through the analysis of the operational management, formulate rules and ejector gas well production system, with the characteristics of low temperature separation in yulin gas field matching jet drainage technology. After injection technology, application of gas drainage continuously and smoothly to intermittent operation, effectively improve the intermittent open when gas production rate and contribution to improve economic efficiency, field.
