  • Publication number: 20200018156
    Abstract: Disclosed is a downhole vibration and impact data recording method, comprising: performing analog-to-digital conversion on analog data, outputting digital format data obtained at a sampling rate f1, and performing sampling storage processing and analysis storage processing on the same. The sampling storage processing includes outputting the digital format data obtained at a sampling rate fn through multiple samplings; storing the same continuously into a storage module. The analysis storage processing includes: buffering the digital format data obtained at the sampling rate f1 into a memory; analyzing the same to determine whether an impact event occurs, and if yes, storing the current data in the memory into the storage module, and then jumping back to the buffering step; otherwise, jumping directly back to the buffering step. With the above method, the amount of data storage can be effectively reduced, while the characteristics of the vibration and impact data can be analyzed.

  • Patent number: 10443307
    Abstract: The static push-the-bit articulated high-built-rate rotary steerable tool has the main body of a non-rotary measurement and control unit articulated with the main body of a non-rotary actuator, rather than an integral structure. Due to the fact that the drilling tool is easy to bend in a wellbore, the bending stress in an upper portion of the steerable tool is low, and the consumption of the pushing force for bending deformation of the drilling tool is minimized. Since the steering sleeve around the main body of a load-bearing actuator only slides along the well wall in an axial direction without rotational friction there-between, the service life of the steering sleeve is long. Besides, since hydraulic pressure is used instead of pressure difference of mud to act on the pistons to form the pushing force, the pushing force is greatly improved, and the sealing life of the pistons is longer.

  • Patent number: 10364670
    Abstract: An azimuthally acoustic imaging logging while drilling (LWD) apparatus employs two sets of transmitting transducers to excite multipole mode waves. One set is high-frequency monopole and polarized pole transmitting transducers, and the other set is low-frequency dipole and quadrupole transmitting transducers. Separation of a high-frequency transmitting state from a low-frequency transmitting state is realized by using a dual-row transmission solution. Each set of transmitting transducers operates at transducer resonance points through a matching circuit, thereby greatly increasing the transmitted energy.
