| Abstract: | The drilling design and accident prevention measures of large diameter gas pipeline on the surface of Huaheyu Mine of Wukuang were studied.The strata and drillability of the mine were analyzed,and the thickness,burial depth and drillability of the regional stratum lithology were obtained.The drilling construction process,drilling construction method,drilling tool assembly,drilling parameters and drilling fluid were studied,and logging and cementing were designed.Gas drainage was carried out by drilling large diameter gas pipelines on the ground,so as to achieve the purpose of pre-depressurization and drainage of coal seam gas in the working face. |
