Drilling and incident treatment for well Xiangyongdi1

Abstract:

The paper introduces the outline of well Xiangyongdi1 for shale gas geological survey, with emphasis on drilling and incident treatment. This paper summarizes the typical cases of drilling incident treatment in well Xiangyongdi1 well, and analyzes the drilling process and drilling results in respect of the actual drilling strata and logging data. With the diamond wireline core drilling technology, every technical index of well completion entirely meets the requirements of geological design. Well Xiangyongdi1 is the deepest shale gas survey well drilled in Hunan province at present. The incidents and complex problems encountered in the drilling process, such as leakage, burning of bits, drill pipe breakage, etc., have been well solved. With execution of the project, a set of deepwell drilling and inhole incident treament technology system for shale gas geological survey well has been formed.
