摘要： A method of processing seismic data, said seismic data having been obtained by: performing a plurality of sweeps, wherein each sweep comprises generating seismic signals in the earth (1) using a plurality of vibrators (4a-4d) by applying a pilot sweep waveform to each vibrator, each pilot sweep being a waveform of changing frequency; measuring the force applied to the earth by each vibrator to determine a measured force waveform; and measuring the seismic signals at one or more locations (5a-5e) remote from the vibrators; said method comprising: filtering the measured force waveform to remove harmonics of the pilot sweep and thus determining a filtered force waveform; generating an inversion operator from the filtered force waveform for each vibrator; and applying said inversion operator to the measured seismic signals to determine the contribution of each vibrator to the seismic signals.

摘要： Making measurements with a main borehole and a microborehole extending from the main boehole into the formation, is performed with sensing devices positioned to measure at zones located in the microborehole. One or more packers can be installed in the microborehole to hydraulically isolate the measurement zones from each other and/or main borehole. In a microborehole fluid samples can be taken, fluid tracers be injected and various sensors including geophones can be incorporated.

摘要： A method of downlinking to a downhole tool located in a borehole is provided. The downhole tool detects transitions in the flow velocity of fluid circulating in the borehole at the downhole tool. To provide for the detection of the transitions fluid is pumped into the drillstring so that it circulates in the borehole at the downhole tool and the the pumping rate of fluid into the drillstring is either increased to a rate which overshoots a steady state pumping rate needed to produce a transition or is decreased to a rate which undershoots a steady state pumping rate needed to produce a transition.

摘要： Methods and systems are disclosed for downhole processing of measurements made in a wellbore during the construction of the wellbore. The system includes a sensors located downhole adapted to measure a two downhole parameters. The system uses a downhole processor to calculate a statistical relationship, preferably covariance, between the two downhole parameters. A transmitter located downhole and in communication with the downhole processor is used to transmit the calculated statistical relationship to the surface. At the surface the statistical relationship is compared with surface acquired data and surface drilling operating parameters are altered based on the statistical relationship.

摘要： A percussive drilling system 22 comprises a drill bit 40 having a bit body 41 with a plurality of mechanical cutters 36 and a directed energy mechanism 38 to direct energy into a formation 30, wherein the energy from the directed energy mechanism 38 causes fracturing of the surrounding formation 30 to facilitate drilling. In further embodiments, the energy could be an electromagnetic energy, laser energy, electric pulses or electrohydraulic energy. The energy could also be used for directional drilling by selectively focusing the energy at a point of deviation 34.

摘要： A bottom hole assembly has a drill bit 2 and an under-reamer 1 on the up-hole side of the drill bit 2. The assembly includes a compliant element 6, possibly in the form of a spring, which is positioned below the under-reamer 1, allowing relative displacement between the drill bit 2 and under-reamer 1. A sensor 3 and transmitter 4 may also be included to measure the weight-on-bit and the applied torque to the drill bit 2 and to transmit the data to the surface.

摘要： An in-situ method for evaluating formation strength (eg yield strength, failure strength) comprises obtaining radial formation property measurements at different wellbore pressures and comparing these measurements with a radial stress function which is based on a formation model (eg linear or non-linear elastic, elasto-plastic, plastic or explicit constitutive models) and estimates of far-field stresses (vertical, maximum and minimum horizontal stresses) and wellbore radial stress. The measurements may be acoustic measurements of shear, compressional or Stoneley slowness, or any other measurements (eg resistivity or spontaneous potential) that respond to changes in the wellbore pressure. The changes in wellbore pressure may be encountered during normal drilling activity (eg turning pumps on and off, changing mud weights), or may be actively instigated by the driller.
