Abstract

A method, and a computer readable medium for performing the method, for selecting drilling operating parameters for a drilling unit comprises characterizing at least one drilling response parameter with respect to lithology, when a parameter related to drill string dissipative motion falls below a selected threshold; measuring the drilling response parameter during drilling and determining lithology from the measured drilling response parameter; selecting at least one drilling operating parameter to optimize at least one drilling response parameter when a parameter related to drill string dissipative motion falls below a selected threshold for the determined lithology; and using the optimized drilling response parameter to operate the drilling unit so as to minimize the drill string dissipative motion. The invention provides improved accuracy and efficiency in operating the drilling unit.

Claims (12)

1. A method for selecting drilling operating parameters, comprising:
characterizing at least one drilling response parameter with respect to lithology, the characterization being performed when a parameter related to drill string dissipative motion falls below a selected threshold;

measuring the at least one drilling response parameter during drilling;
determining lithology from the measured drilling response parameter; and selecting at least one drilling operating parameter to optimize at least one drilling response parameter when a parameter related to drill string dissipative motion falls below a selected threshold for the determined lithology.
2. The method of claim 1 wherein the drilling response parameter optimized during drilling is the same drilling response parameter characterized with respect to lithology.
3. The method of claim 1 or claim 2 wherein the at least one drilling operating parameter comprises one of weight on bit, rotary speed and drilling fluid flow rate.
4. The method of claim 1 or claim 2 wherein the at least one drilling response parameter comprises one of rate of penetration and drill string acceleration.
5. The method of any one of claims 1 to 4 wherein the characterizing comprises measuring at least one property related to at least one of composition and mechanical properties of earth formations, and determining the correspondence between the drilling operating parameter and the drilling response parameter within formations having similar lithology.
6. The method of claim 5 wherein the at least one property comprises one of lithological description, formation hardness, electrical resistivity, acoustic interval travel time, natural gamma radiation, neutron porosity and bulk density.
7. A computer readable medium having recorded thereon computer readable instructions for performing steps comprising:

characterizing at least one drilling response parameter according to a lithology, the characterization being performed when a parameter related to drill string dissipative motion falls below a selected threshold;
measuring the at least one drilling response parameter during drilling;
determining lithology from the measured drilling response parameter; and selecting at least one drilling operating parameter to optimize at least one drilling response parameter when a drill string dissipative motion parameter falls below a selected threshold for the determined lithology.
8. The computer readable medium of claim 7 wherein the drilling response parameter optimized during drilling is the same drilling response parameter characterized with respect to lithology.
9. The computer readable medium of claim 7 or claim 8 wherein the at least one drilling operating parameter comprises at least one of weight on bit, rotary speed and drilling fluid flow rate.
10. The computer readable medium of any one of claims 7 to 9 wherein the at least one drilling response parameter comprises at least one of rate of penetration and drill string acceleration.
11. The computer readable medium of any one of claims 7 to 10 wherein the characterizing comprises measuring at least one property related to at least one of composition and mechanical properties of earth formations, and determining the correspondence between the drilling operating parameter and the drilling response parameter within formations having similar values of lithology.
12. The computer readable medium of claim 11 wherein the at least one property comprises at least one of electrical resistivity, acoustic interval travel time, natural gamma radiation, neutron porosity and bulk density.
