喷射引流技术在榆林气田的应用研究
|
摘要
榆林气田南区目前有23口气井为间歇气井,2008年开井时率为27.39%,该类气井由于有效控制范围小、气井产能低,开井后压力下降快,不能连续生产.目前主要采取“长开短关”、“短开长关”、“冬季长关、夏季间开”三种生产制度,难以有效发挥气井的产能。在分析榆林气田间歇气井生产现状基础上,评价目前的采气工艺,并提出存在问题,结合气田及气井特征,研究出适用于榆林气田的喷射引流配套工艺技术,并现场进行改造安装,开展试验,同时模拟装置内部流场流动规律,对装置参数进行核算。通过总结、分析,制定了装置运行管理规定及引射气井生产制度,形成具有榆林气田特色的低温分离配套喷射引流工艺技术。应用喷射引流技术后,间歇气井能够连续、平稳运行,有效提高了间歇气井开井时率和产气贡献率,提高田开发经济效益。
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.
