| Abstract: | The upper continental formations mainly consist of sand stones and shale in Heba 1 Well, and comprise little coal beds. The marine strata mainly consist of lime stones, dolomites, gypsums, and have little shale. Because of large difference of formation pressure factors, 24 lost circulations with the total leaking volume of 1855. 76 m3 happened during the drilling operation. The paper analyzes the features of lost circulation, introduces preventive measures and several sealing technologies applied in the practices. In addition, some technical challenges to sealing operations are also put forward while drilling in this area. |
