A new technology assessment method for high-temperature and high-pressure gas wells
Keywords:
applicability analysis, failure modeAbstract
The integrity of high-temperature and high-pressure (HTHP) gas well is usually vulnerable to multiple risks. It is necessary to integrate new technologies to address the potential risks. In the Kuqa piedmont of the Tarim Oilfield, where the application of new technologies to HTHP gas wells is very challenging, a new technology assessment method for HTHP gas wells was established by integrating technology assessment method, risk assessment method, and performance assessment method. The new technology assessment method can be used to evaluate the potential risks, failure modes, technical defects, and applicable conditions for a new technology, so as to determine the application scope, application requirements, and aspects to be improved. The analysis on packer application shows that after considering the impact of existing technical control measures on risk reduction, the proportions of risky components and risky parts can be quickly obtained for subsequent targeted verification testing and improving the reliability and environment adaptability of the packers. The new technology assessment method can effectively promote the popularization, application, and continuous improvement of new technologies for HTHP gas wells. © 2023 Well Testing.
