摘要

为快速确定不同气井最优排水采气技术及时机,通过对 Turner模型、Coleman模型、Li Min模型和Yang Chuandong模型优选和分析,得到了适合大庆油田的临界携液流量修正模型.利用该模型,建立了日产气量、水气比和井深的三维图版,结合不同排水采气工艺的技术界限,得到不同区域的排水采气技术三维图版.研究结果表明,修正模型适用于大庆油田气井的临界携液流量计算,准确率接近90%.该研究成果为大庆油田高效、快速开发提供了技术支持.%To determine optimal drainage gas production technologies and application time for different gas wells quickly and effectively,Turner Model,Coleman Model,Li Min Model and Yang Chuandong Model have been re-viewed and analyzed to highlight the modified model with critical fluid-carrying flow suitable for the Daqing Oil-field. By using the newly-development model,it is possible to establish the 3D chart for the daily gas productivity, water/gas ratio and well depth. At the same time,with consideration to technical limitations of various drainage gas production processes,optimal drainage gas production techniques for different zones of the 3D chart can be identi-fied. Research results show the modified model can be used effectively for calculation of critical fluid-carrying flow in gas wells of the Daqing Oilfield with accuracy up to 90%. Relevant research results may provide technical sup-ports for fast and high-efficiency development of the Daqing Oilfield.
