针对目前研究区气田实际开发过程中工作制度不合理的情况,利用节点分析方法,建立嘴流模型进行分析研究,以达到确定合理工作制度的目的。研究表明,建立的嘴流公式计算的理论产气量与实际产气量较为吻合,平均误差9.5%。根据此嘴流公式计算结果,进一步优化投产井合理产量和工作制度。为该研究为后期生产过程有效利用气藏天然能量,控制单井递减,改善气藏开发效果提供指导依据。
In view of the unreasonable work system in the actual gas field development in the research area at present, this paper uses the node analysis method to establish the mouth flow model to analyze and research so as to achieve the goal of determining the reasonable work system. The research shows that the theoretical gas production calculated by the established mouth flow formula is in good agreement with the actual gas production, with an average error of 9.5%. According to this mouth flow formula to calculate the results, to further optimize the rational production volume and working system. This study provides the basis for the effective utilization of natural gas in the later production process, controlling the decrease of single well and improving the effect of gas reservoir development.
