Northwestern Margin

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.

Fractures in Carboniferous volcanic rocks located at Zhongguai Area (China) highly influence the accumulation and productivity of oil and gas. As such, the study of development periods and genetic mechanisms of tectonic fractures could throw useful information regarding the evaluation and development of that reservoir. Their tectonic origins caused high-angle and oblique shear fractures. The primary orientation of those fractures appears close to EW (270°±10°), NW (300°±15°), NE (45°±15°), and SN (0°±10°). At least four fracture generations can be found in Carboniferous volcanic rocks at Zhongguai Area. Combined with a tectonic evolution, they are based on the segmentation relationship of the fracture fillings, the thermometry measurement of the fracture filling inclusion, and the acoustic emission, as well. Affected by a new horizontal principal stress, the opening and permeability of nearly EW fractures are the best. In this way, a priority in the development of well's patterns should be considered close to EW fractures. The pressure change in the process of exploitation may damage the reservoir permeability of fractured volcano rocks severely. Accordingly, well patterns should be adjusted to dynamic changes of permeability happened during the oilfield development since some differences have been detected in distinct fracture sets.

This article focuses on the possibility of using an innovative drilling method for the implementation of underground works, especially where there is no physical possibility of using large working machines. Work on a model carried out under the INDIRES project is discussed. A design of a drilling tool equipped with the proposed technology is presented. The solution in question makes it possible to increase the efficiency of the drilling process, which is confirmed by computer simulations. Also, introductory tests of a drilling process supported by torsional vibration generated by an electromagnetic torque generator provided in the KOMAG laboratory facility show the reduction of the drilling time by almost two-fold. In our opinion, adding torsional vibration acting on the plane of a drilled wall that equals natural frequencies of the drilled material represents a promising new technology for drilling. The presented work constitutes the basis for the development of the proposed technology and allows us to conclude that the developed method will be of great interest to manufacturers of drilling machines and devices.
