提高新疆油田稠油水平井举升工艺技术应用效果

AN ENHANCED APPLICATION OF LIFTING TECHNOLOGY TO HEAVY OIL HORIZONTAL WELLS OF XINJIANG OILFIELD

对新疆油田自2005年大规模采用水平井进行稠油油藏开发,对稠油水平井技术现状进行了介绍。分析对比了稠油水平井的举升工艺的适应性,对新疆油田500多口稠油水平井举升工艺技术中存在的问题进行分析,提出了针对措施和技术对策,进行了应用效果及经济性分析。通过以上分析,提出了稠油水平井举升工艺技术应用以来的认识,并提出了下一步的工作建议。通过对稠油水平井举升工艺技术分析对比,提出的相关技术对策,为提高稠油水平井的挖潜增效提供有力的技术支持。

This paper gives a general description of the application of technologies to heavy oil horizontal well since 2005 when the heavy oil reserve was developed by drilling the horizontal wells at a large scale,analyzing the feasibilities of different lifting technologies used for horizontal wells recovery.Many hazards resulted from the application of lifting technologies to the more than 500 horizontal wells of Xinjianji oilfields have been analyzed and then countermeasures are put forward.A general idea of the application oi lifting technologies came to being with regard to the effectiveness and economy of these technologies,and then advanced suggestions to better the future heavy oil recovery are presented so as to give a strong technical support for stimulation of heavy oil recovery.
