Exploration and practice of energy efficiency under natural gas well drainage and gas production process method

Natural gas, as a key fossil fuel, plays a vital role in the energy industry. This paper explores three drainage and gas production technologies - foam drainage, beam pumping unit deep well pump drainage, and gas lift drainage - with a focus on improving energy efficiency. By analysing experimental data, the study compares their performance in terms of cost and efficiency. At a drainage depth of 200 m, foam drainage was found to be the most cost-effective, reducing gas production costs by 170.02 yuan and 183.9 yuan compared to the other two methods. While energy efficiency among the three methods showed little difference, foam drainage is recommended for its lower cost, contributing to energy savings and technological advancement in natural gas production.
