Abstract:The gradual promotion of the concept of gas well integrity has made major oil and gas fields pay more and more attention to the integrity management and evaluation of gas wells with annular pressure. Annular leakage rate is one of the key parameters for gas well integrity evaluation. However, the leakage rate measurement of high-temperature, high-pressure, and acid-containing gas wells has high risks and costs, which are often difficult to obtain in field operations. In order to obtain the bottom hole leakage … Show more
