Application of Flexible Bottom Hole Assembly in Eight Rrgion of Xinjiang Oilfield

Abstract:

The results of inclining-prevention are not so ideal while drilling in easily declined formations by pendulum assembly with stabilizers. It was found in continuous practices and calculation, the flexible bottom hole assembly has the advantages of strong pendulum force, good incllning-prevention results, and which ensure the well bore quality and improve ROP. A new type bottom hole assembly is provided for drilling in high angle deviated and hard formation.
