Experimental Application of TorkBuster Torsion Compactor in Exploration Wells of Junggar Basin

Abstract:

The northwestern margin of Junggar Basin is one of the most prolific petroliferous areas in Junggar Basin. While there exists many drilling problems, such as poor drillability, low drilling penetration rate (ROP) and long drilling cycle time due to the complex lithology and pressure system in low formation, big pressure change, several sets of coexisted formation pressure system of northwestern margin. In order to improve ROP, make better use of resources and solve these drilling problems, utilizing the TorkBuster Torsion Compactor (TorkBuster) with personalized PDC bit has been introduced in the northwestern margin. This paper presented the workings, technology characteristics and experimental application of TorkBuster in Ma13(M) well areas. The application results showed that the speedup effect of this drilling tool was obvious and drilling cycle time was shortened substantially. The technology has provided a fast and effective drilling method for Karamay Formation and Wuerhe Formation of Triassic in northwestern margin of Junggar Basin.
