Drilling technology of Well Qianpudi-1 for basic geological survey of shale gas in Southern China

Abstract:

The Well Qianpudi-1 is a shale gas geological survey well deployed in the Qingshan syncline in Southwest Guizhou Sag. This paper describes the outline of the project and the basic geology with focus on the drilling and construction technology of the well. In addition, the drilling quality is analyzed in light of drilling formation and logging data. With proper drilling equipment selection, well structure optimization, core drilling technology, drilling fluid system optimization and proper drilling parameters, drilling efficiency has been improved, and drilling quality met the geological requirements, resulting in effective completion of the drilling work. It may provide technical reference for drilling and construction of similar shale gas survey wells.
