【摘要】：当前,苏里格气田水平井开发规模不断扩大,水平井的后续开发面临着生产规律不清的问题,需要开展水平井产能规模的核定、开采特征的评价和管理措施的制定并跟踪分析生产动态特征。本文在前人研究成果的基础上,总结研究区气藏地质特征；通过对苏14水平井开发区已开展试采的水平井试采资料进行分析,综合应用气藏工程、渗流理论和试井解释、动态描述、数值模拟等多种手段,结合实测地层压力和试井解释,落实研究区当前地层压力及气井控制储量,确定水平气井的产能,分析影响水平井产能的主控因素；通过单井递减研究分析,掌握气井产量递减规律。基于动态静态资料,分析不同配产条件下水平井的生产规律和产水规律,提出水平井不同生产阶段的管理措施。综合以上研究,提出气井合理的开采制度及建议,指导生产,为合理、高效开发气藏提供技术支持,以实现气田经济有效开发。
[Abstract]:At present, the scale of horizontal well development in Sulige gas field is constantly expanding, and the follow-up development of horizontal well is faced with the problem of unclear production rules. It is necessary to carry out the verification of horizontal well production capacity scale. On the basis of the previous research results, this paper summarizes the geological characteristics of gas reservoirs in the study area. Based on the analysis of the production test data of horizontal wells developed in Su14 horizontal well Development Zone, gas reservoir engineering, percolation theory and well test interpretation, dynamic description, numerical simulation, etc., combined with measured formation pressure and well test interpretation, are applied synthetically. The present formation pressure and controlled reserves of gas wells in the study area are carried out, the productivity of horizontal gas wells is determined, the main controlling factors affecting productivity of horizontal wells are analyzed, the laws of production decline of gas wells are grasped through the research and analysis of single well decline, and based on dynamic and static data, This paper analyzes the production law and water production law of horizontal wells under different production distribution conditions, and puts forward the management measures for horizontal wells in different production stages. By synthesizing the above research, the reasonable production system and suggestions for gas wells are put forward to guide production. High-efficiency gas reservoir development provides technical support to realize economic and effective development of gas field.
