    摘要： Examples of techniques for performing a wellbore construction operation in a wellbore are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes: performing a rheology test on a test fluid, the test fluid being representative of a fluid pumped through the wellbore, to generate test fluid data; performing, by the processing device, a data analysis on the test fluid data to generate at least one parameterized correlation; measuring a first property of the fluid to generate measured data; calculating, by the processing device, a second property of the fluid in the wellbore by using the parameterized correlations and the measured data to generate calculated data; and changing a parameter of the wellbore construction operation based at least in part on the calculated data.

    摘要： A method for estimating a time at which a pressure window relevant observation occurred relating to an event that occurred in an open borehole penetrating an earth formation includes: receiving with a processor a pressure window relevant observation that provides input to adjusting a pressure window for drilling fluid for drilling the borehole; and estimating with the processor a time window in which a physical parameter, a chemical parameter, or a process that caused the pressure window relevant observation to occur, the time window having a start time and an end time.

    摘要： Disclosed herein is a method of locating and quantifying friction between a drillstring and a wellbore. The method includes, positioning a plurality of sensors within a wellbore, communicatively coupling the plurality of sensors, monitoring signals from the plurality of sensors, logging the sensed signals versus time versus depth of each of the plurality of sensors, locating at least one friction zone along the drillstring within the wellbore based on the logging and quantifying friction in the at least one friction zone based on the logging.

    摘要： A method of drilling a borehole in an earth formation includes deploying a drilling assembly including a drill bit and a drill string, and performing a drilling operation according to one or more operational parameters to advance the drilling assembly through the formation, wherein performing the drilling operation includes rotating the drill bit and at least a portion of the drill string. The method also includes, during the advancing, monitoring a downhole condition, determining whether the downhole condition indicates at least one of a cuttings accumulation in the borehole and wear of a downhole component, and in response to the downhole condition indicating the cuttings accumulation or the wear, adjusting at least one operational parameter to induce or adjust an oscillating motion in the drill string, the oscillating motion causing at least one of a reduction in the cuttings accumulation and a reduction of wear of the downhole component.
