榆林南区低产井“低配长稳八有利”开发管理技术

Development Management Technologies of ＂Low-Production Proration with Long Stability and Eight Favorable＂Measures for Low-Yield Wells in Southern Yulin Gasfield

低产气井物性差，生产能力弱，开发管理难度大。因此，对于该类井以静、动态特征相结合，进行精细分类，进一步分析不同类型井的动态特征。基于气藏工程理论，考虑适应气藏供气能力、保护储层、提高采收率、降低生产管理成本等因素，提出了低产井”低配长稳”配套工艺措施的开发管理技术，实现了低产井开发的”八有利”。

The physical nature of gas wells with low production is poor, with weak production capacity, and difficult development and management. Therefore, to such wells, combining the static and dynamic features, and fine classification, dynamic features of the gas wells of different types are further analyzed. Based on the gas reservoir engineer- ing theory, with consideration of the gas supply capacity of gas reservoirs, the reservoir protection, enhanced oil recovery, lower production costs and other factors, the authors put forward a development and management technique of ＂low-production proration with long stabilization＂ complementary measures for low-yield wells. The development of low-yield gas wells is achieved by ＂eight beneficial＂ measures.
