    摘要： The invention provides a method of optimizing the rate of penetration of a hydraulically or pneumatically powered rotor and stator driven drill as it drills a wellbore into the earth, the method comprising: (a) measuring a first set of rotor and stator operating parameters including the weight applied to the drill bit, the speed of rotation of the rotor and rotor torque for a first period of time, (b) generating a first set of relationships from the first set of operating parameters to enable the rotor speed and rotor torque to be predicted over a range of operating parameter values, (c) determining the rate of penetration for the first period of time from measurements of weight applied to the bit and rotation speed of the bit, (d) determining whether any other combination of weight applied to bit and rotation speed of bit, provided by the relationships determined in step (b) are capable of providing a greater rate of penetration, and (e) adjusting at least one operating parameter to move the weight applied to bit and/or speed of rotation of bit towards the combination which provides a first greater rate of penetration.

    摘要： A method and system for real time updating of an earth model. The efficiency with which an oil or gas well is constructed can be enhanced by updating the relevant earth model using real-time measurements of the effective density of the drilling fluid and other parameters. The method includes generating an earth model used for predicting potential problems in drilling of a borehole having a predetermined trajectory. Evaluations of the state of the borehole and local geological features are obtained which are based on the earth model. Real time data is used to create a diagnosis of the state of the borehole and local geological features. The evaluations are compared with a diagnosis to identify inconsistencies. A component of the earth model is identified that is both related to the identified inconsistency and has a high degree of uncertainty. The selected component of the earth model is then updated prior to completing construction of the borehole using the received data.
