In this paper,based on previous empirical statistical formula and available observed data,especially the full and accurate tropical cyclone central pressure data,a new scheme for adjusting the tropical cyclone maximum wind speed radius is proposed,and the new scheme can make the maximum wind speed radius well reflect the tropical cyclone wind field.

Optimization of well killing method for high pressure gas wells;

Application examples of gas logging parameters combined with drilling time in the well control of the high pressure gas well.;

Thread sealing property in high temperature and high pressure gas wells is more important than that in oil wells.
