摘要： The present invention is a moisture stabilization control system used to prevent structural damage to foundations resulting from forces exerted by the expansion and contraction of underlying soil. Stress sensors are employed to monitor the stress applied against the foudnation. When abnormal amounts of stress are sensed by the system, it compensates for the decreased support of the foundation by injecting water into the soil supporting that foundation until the level of stress is equalized and at the proper amount. The present invention is designed such that it can provide water to the soil in specified zones, thereby relieving localized depletions and preventing substantial structural damage to any foundation.

摘要： Apparatus for monitoring vibration of a bottom hole assembly used to drill a well includes at least one accelerometer mounted in the bottom hole assembly to generate data in the form of electrical signals corresponding to the acceleration experienced by the assembly. The computer in the assembly is programmed to collect data from the accelerometer and compute magnitude of the assembly acceleration. Means are provided for selecting from the collected data a value which exceeds a preset level. In one form, when the collected data has a value above a preset level, an alarm signal is sent to the surface so corrective measures can be taken to prevent damage to downhole equipment.

摘要： A method is provided which, in an embodiment described herein, permits a location and/or displacement of a cementing plug to be determined during a cementing operation. In this embodiment, one or more pressure pulses are transmitted through displacement fluid being used to pump the plug through the casing string. The pressure pulses are reflected off of the plug and received by a pressure sensor. Information regarding the timing of the reflected pressure pulses may be used to determine the location and/or displacement of the plug.

摘要： A transducer is described especially for use in providing acoustic transmission in a borehole. The transducer includes a multiple number of magnetic circuit gaps and electrical windings that have been found to provide the power necessary for acoustic operation in a borehole while still meeting the stringent dimensional criteria necessitated by boreholes. Various embodiments conforming to the design are described. Moreover, the invention includes transition and reflector sections, as well as a directional coupler and resonator arrangement particularly adapted for borehole acoustic communication. An acoustic communication system is described especially designed for use in providing acoustic transmission of information in a borehole. The communication system comprises a surface transceiver and at least one downhole transceiver. The surface transceiver operates in conjunction with a host computer that sends commands to the downhole transceiver. Subsequently, the downhole transceiver transmits encoded data from subsurface, borehole sensors to the surface transceiver. The preferred embodiment uses Minimum Shift Keying (MSK) modulation for both transmitting commands to the downhole unit and for transmitting data to the surface transceiver. To facilitate operation of a coherent communication system in the inhospitable environment of a borehole, the acoustic channel is characterized to enable the system to choose the best possible frequency and bandwidth for communication transmission. Additionally, the system achieves synchronous operation by transmitting synchronization signals between the downhole transceiver and the surface transceiver prior to the units exchanging commands and data.
