随着社会经济的不断进步和发展,社会生产和生活对油气资源的需求不断增加,天然气勘探开发的规模也随之不断扩大。随着天然气开发的不断深入,在天然气储气库注采井的油管选择上也有了多种选择,油管的直径和材质的选择对天然气地下储气库的安全正常生产具有至关重要的意义,所以对油管的选择要经过科学合理的分析论证。笔者在本文中通过计算分析对油管的直径选择做出了判断,通过对注采井的采气期腐蚀情况分析,对油管的材质选择做出了判断。
With the continuous improvement of social economy and development, the demand for oil and gas in social production and daily life is constantly increasing, and the scale of natural gas exploration and development also expands. With the continuous development of natural gas, there are many choices for the selection of tubing in natural gas storage well. The selection of tubing diameter and material is of vital importance to the safe and normal production of natural gas underground storage. Therefore, the choice of tubing to go through scientific and rational analysis. In this paper, the author makes a judgment on the diameter selection of tubing by calculation and analysis. Through the analysis of corrosion during the gas recovery period of injection and production wells, the author makes a judgment on the material selection of tubing.
