    摘要: A method of optimizing drilling ramp-up is provided herein. More specifically, a method of ramping up a drilling operation from a static condition (0, 0) to optimum drilling parameter values (WOB*, RPM*) is provided. The method includes identifying a set of drilling control variables used in forming the wellbore. Examples include weight-on-bit (WOB) and rate of penetration (RPM). The method additionally includes selecting desired control variable values for a first identified drilling stage. The values may be generically referred to as (V1, V2). The method also includes increasing the drilling control variables from (0, 0) to pre-defined drilling control variable values (V1, V2). Preferably, V1 is a WOB value while V2 is a rotation speed value (RPM). The method also comprises monitoring a performance index (PI), wherein (PI) is a combination of torque (TQ) and penetration rate (RPM). The method then includes determining an optimal path to optimum drilling parameter values (WOB*, RPM*) using the Performance Index (PI).

    摘要: Integrated methods and systems for optimizing drilling related operations include recording data, parsing the data into intervals and analyzing the intervals to determine if the performance data in each time interval is of sufficient quality for using the interval data in a performance optimization process. The quality assessment may involve evaluating the data against a set of determined standards or ranges. The performance optimization process may utilize data mapping and/or modeling to make performance optimization process recommendations.

    摘要: Methods and systems for detecting downhole bit dysfunction in a drill bit penetrating a subterranean formation comprising receiving a plurality of drilling parameters characterizing a wellbore drilling operation and calculating bit aggressiveness (μ) at each of a plurality of points during drilling, wherein each point corresponds to time, depth, or both. A depth-of-cut (DOC), time derivative of bit aggressiveness ({dot over (μ)}), calculated as dμ/dt, or both, is calculated at each of the plurality of points. A two-dimensional data representation of the plurality of points, comprising μ in one dimension and DOC, {dot over (μ)}, or both, in another dimension is created. Data features are extracted from the two-dimensional data representation and downhole bit dysfunction is identified by comparing the extracted data features with predefined criteria.
