摘要： This invention relates to flowable devices and methods of utilizing such flowable devices in wellbores to provide communicate between surface and downhole instruments, among downhole devices, establish a communication network in the wellbore, act as sensors, and act as power transfer devices. The flowable devices are adapted to move with a fluid flowing in the wellbore. The flowable device may be memory device or a device that can provide a measure of a parameter of interest or act as a power transfer device. The flowable devices are introduced into the flow of a fluid flowing in the wellbore. The fluid moves the device in the wellbore. If the device is a data exchange device, it may be channeled in a manner that enables a device in the wellbore to interact with the memory device, which may include retrieving information from the flowable device and/or recording information on the flowable device. The sensor in a flowable device can take a variety of measurement(s) in the wellbore. The flowable devices return to the surface with the returning fluid.

摘要： A formation fluid sampling and hydraulic testing tool for a drilling apparatus that includes a drilling string comprised of a drilling pipe and a drilling bit is provided. The tool has an outer tube disposed between the drilling pipe and the drilling bit. The outer tube is provided with a plurality of through holes for receiving formation fluid into the outer tube. An inner tube is disposed within, and spaced from, the outer tube to form an annular space between them. The inner tube is provided with a plurality of through holes that are adapted to communicate with the annular space. One end of the inner tube is connectable to a pumping mechanism for drawing formation fluid through the through holes of the outer tube and of the inner tube for the purpose of collecting a sample of the fluid and imposing a hydraulic stress on the formation. The through holes of the inner tube can be closed off or released. Valves are provided for establishing or closing off communication between the interior of the inner tube and the open ends of the outer tube.

摘要： An apparatus and method for determining permeability of a subterranean formation is provided. The apparatus and method comprise a work string, at least one selectively extendable member mounted on the work string to isolate a portion of the annular space between the work string and borehole. A predetermined distance proportional to the radius of a control port separates at least two ports in the work string. A sensor operatively associated with each port is mounted in the work string for measuring at least one characteristic such as pressure of the fluid in the isolated section.

摘要： In order to measure forces F exerted on a part in a given direction and in the presence of an external pressure p, the part has integrated therein a sensor (10) which delivers an output signal of the form S=&agr;.F+&bgr;.p+&ggr;, and said sensor is dimensioned in such a manner as to cause the coefficient &bgr; to be zero. To this end, a sensor (10) is used that includes a tube (12) formed by a thinner walled portion (12a) and a thicker walled portion (12b), together with strain gauges (16a, 16b, 18a, 20) mounted in the tube (12) and interconnected to form a Wheatstone bridge.

摘要： Methods and apparatus are provided which permit well testing operations to be performed downhole in a subterranean well. In various described methods, fluids flowed from a formation during a test may be disposed of downhole by injecting the fluids into the formation from which they were produced, or by injecting the fluids into another formation. In several of the embodiments of the invention, apparatus utilized in the methods permit convenient retrieval of samples of the formation fluids and provide enhanced data acquisition for monitoring of the test and for evaluation of the formation fluids.
