Study on drillability of rocks in Junggar basin

The micro-aiguille drillability tester is employed to test the drillability of rock core in the main block in Junggar Basin. Consequently,the drillability model is established and perfected.And the stratigraphic drillability profile is established by analyzing the current logging and drilling data, thus providing a reliable basis for the selection standard of aiguille type and the design of drilling parameters.
