摘要： The present invention provides a transmitter for an electromagnetic survey system for transmitting signals having a waveform comprising at least a first pulse and a second pulse, wherein the first and second pulses are different in at least one of shape and power. Embodiments of the invention enable combining various distinct pulses that may have been optimized for respective applications to form a transmitter waveform for conducting a geological survey. In effect, the embodiments of the present invention provides an EM system that is substantially equivalent to multiple EM systems operating at the same time for collecting data in relation to different aspects of the geology of interest. Advantageously, the benefits of the present invention can be obtained without the undesirable complexity and cost associated with the simultaneous deployment of multiple EM systems.

摘要： An electromagnetic (EM) receiver system for measuring EM signals. The EM receiver system includes a platform; a coil for measuring EM signals; and first to third suspension mechanisms located between the platform and the coil so that the coil oscillates relative to the platform, and the first to third suspension mechanisms attenuate motion induced noise introduced by towing the receiver system above ground.

摘要： An artificial toolface reference system includes a power supply providing current to a ground lead and a reference lead. A ground point is coupled to the ground lead and in electrical connection with the ground. A reference wellbore includes a reference conductor in electrical connection with the ground. The reference conductor is in electrical connection with the reference lead. The reference conductor includes an uninsulated portion and an insulated portion having an insulating layer positioned thereabout. A guidance sensor positioned outside the reference wellbore includes at least one magnetometer. The power supply may be used to provide a current through the reference conductor, into the ground through the uninsulated portion, and the ground point such that a reference magnetic field is generated along the reference conductor. The guidance sensor may measure the reference magnetic field with a magnetometer. An artificial magnetic toolface may be calculated therefrom.

摘要： The present invention provides an airborne electromagnetic receiver having a large dimension to allow low transmitter base frequency. A modular and configurable suspension assembly is provided for use within a receiver support structure and suspending the support structure. The suspension assembly has a rigid support having a suspension portion, and links connecting the suspension portion and the suspended structure. The links are adjustable in length and tension to radially suspend said equipment support structure. The natural frequency of the suspension assembly and the suspended receiver motion can be optimized by adjusting mass distribution, suspension link length and suspension link tension. The suspension assembly can be used to suspend a receiver having large receiver coils. The suspension assembly converts high frequency vibration forces imparted on the receiver to a low frequency oscillation. The suspension assembly may also be tuned to avoid coincidence with the excitation frequencies.
