摘要： A system for drilling a borehole is disclosed. The system may include drill string having a bottom hole assembly a nuclear magnetic resonance tool within the bottom hole assembly, and a surface control system including a nuclear magnetic resonance measurement quality map. The control system may be configured to drill a borehole at a first set of drilling parameters and to receive motion properties from the nuclear magnetic resonance tool and adjust the drilling of the bore hole at a second set of drilling parameters. The surface control system may be further configured to adjust the drilling of the bore hole based on the motion properties from the nuclear magnetic resonance tool and the nuclear magnetic resonance measurement quality map.

摘要： A method can include receiving a maximum depth of cut value of a bit that accounts for bit body formation engagement; receiving a total revolution rate value for the bit that is based at least in part on a differential pressure value of a mud motor; generating a rate of penetration value for the bit as operatively coupled to the mud motor by multiplying the maximum depth of cut value and the total revolution rate value; and operating a rigsite system according to the rate of penetration value for drilling a portion of a borehole using the bit as operatively coupled to the mud motor.

摘要： Management of fatigue life includes partitioning a drilling interval into sections, and calculating a stress value for each section. From the stress value, an equivalent alternative stress amplitude is calculated for each location, and a fatigue life consumption value in each section is computed. The fatigue life consumption value across the sections is aggregated to obtain an aggregated fatigue life consumption value, which is presented.

摘要： A method for drilling a well includes applying energy input to a drill string (31) by at least one of rotating the drill string (31) from surface and operating a drilling motor (41) disposed in the drill string (31) to operate a drill bit (2) at a bottom of the drill string (31); an amount of the applied energy not consumed in drilling formations caused by at least one of motion, deformation, and interaction of the drill string (31) is calculated; an amount of the applied energy used to drill formations below the drill bit (2) is calculated; and at least one drilling operating parameter is adjusted based on energy calculation before or during drilling operation.

摘要： A system for simulating a downhole operation including a computing device having a computing processor and computer-readable media storing computer-executable instructions that cause the computing device to use bottomhole assembly parameters, wellbore parameters, drilling operating parameters, and vibration tool parameters or shock tool parameters, to execute a first simulation to generate first performance parameters. The instructions are also configured to cause the computing device to use the BHA parameters, wellbore parameters, drilling operating parameters, and a second set of vibration tool parameters or shock tool parameters to execute a second simulation to generate second performance parameters. By comparing the first and second simulations, a bottomhole assembly may be evaluated, modified, selected, or designed.
