Use of single-cutter data in the analysis of PDC bit designs
- Sandia National Labs. (US)
Research has been conducted for several years at Sandia Natl. Laboratories to foster the development of PDC bits for geothermal drilling. This work has been directed toward the high-temperature, hard-rock drilling environment typically found near geothermal resources. The results, however, can be applied to drilling environments of interest to the petroleum industry as well. Designing and operating PDC bits to perform effectively within the constraints suggested by these wear phenomena are the subjects of this paper. Part 1 presents laboratory work that provides insight and quantitative data on cutter/rock interaction. A cutter-interaction model based on the laboratory results is developed and shown to provide a means for predicting the effects of multiple cutters on a PDC bit face. In Part 2, this model is generalized and used to develop algorithms for a computer code (PDCWEAR) that predicts the performance and wear of PDC drill bits. General trends related to the effects of bit design and operation, as predicted by the code, are also identified and discussed.
