Paper Title:
Study on Borehole Stability in Haita Basin
  Abstract

The geological structure is very complex in Haita Basin, due to the difficult drilling, sidewall instability phenomena happened frequently during drilling process. And it has restricted the drilling speed and the development and exploration process seriously. According to the borehole collapse problems, physical and chemical properties experiment of mud shale had been operated, then we analyzed and predicted borehole stability of Haita Basin by experimental data, discussed the collapse mechanism in this area, and established corresponding countermeasures to prevent the collapse which has laid a good foundation for further research on key drilling technology and improving drilling rate in Haita Basin.
