大牛地气田在经历了速度管大规模的应用后,部分气井出现积液甚至停喷现象。针对目前尚无明确的速度管气井生产方式转换指导理论,本文研究了速度管气井生产方式转换条件,旨在解决因转换不合理造成的气井排液困难问题。由于速度管与小环空的截面积不同,对于不同产气和产液气井所需的举升压力不同,不同的生产方式对于不同气井在排液效果上具有较大的差异。在气田整体增压实施后,管网压力出现明显降低,明确速度管在不同举升压力和产气产液条件下的生产方式以及助排措施能有效保障速度管气井稳产,从而大大提高气井利用率,在气田生产中有着重要的意义。
After experiencing the large-scale application of the velocity pipe, the Daniudi gas field had fluid accumulation and even stopped spraying phenomenon. In view of the fact that there is no clear guideline for the conversion of gas well production mode at present, this paper studies the conversion conditions of the production method of gas pipelines in the gas pipelines and aims to solve the problem of gas well drainage caused by the unreasonable conversion. Due to the different sectional area of the velocity tube and the small annulus, the different lifting modes require different lifting pressures for different gas production and production gas wells, and different production methods have great differences in the drainage effect of different gas wells. After the overall pressurization in the gas field, the pipe network pressure obviously decreased. It is clear that the production mode of the speed pipe under different lifting pressure and gas production and liquid production conditions and the help of the drainage measures can effectively ensure the stable production of the gas pipe and speed up the utilization of the gas well The rate of production in the gas field is of great significance.
