摘要： Electrical power generators and methods of producing power in a subterranean well are provided. In a described embodiment, fluid flow through a fluid conduit causes a member to displace or vibrate. The displacement of the member is utilized to induce strain in a piezoelectric material, thereby causing the piezoelectric material to produce electricity. Various means may be used to create turbulence in the fluid flow, thereby increasing displacement of the member, resulting in increased power output from the generator.

摘要： An apparatus and method for monitoring and reporting downhole bit failure. Sensors are located on a sub assembly (which is removable from the drill bit) and send data to neural net or other adaptive filter. The neural net uses past sensor readings to predict future sensor readings. The value predicted for the sensors is subtracted from the actual value to produce a prediction error. Increases in prediction error are used to indicate bit failure. The results of this are transmitted to the operator by varying the pressure in the drilling mud flow.

摘要： Electric power is generated downhole by changes in annulus pressure. In a described embodiment, a system for generating electric power includes a piston, an accumulator, a reservoir of hydraulic fluid, a turbine, and a generator. A change in annulus pressure causes displacement of the piston due to a pressure differential between the annulus and the accumulator. Piston displacement causes the hydraulic fluid to flow through the turbine, thereby driving the generator to generate electricity.

摘要： An apparatus and method for progressively treating an interval of a wellbore (32) is disclosed. The apparatus comprises a sand control screen (138) that is eccentrically positioned within the wellbore (32) and a fluid delivery tubular (140) that is disposed within the wellbore (32) adjacent to the sand control screen (138). During a treatment process when a treatment fluid is pumped into the fluid delivery tubular (140), the fluid delivery tubular (140) progressively allows the treatment fluid to exit from the interior of the fluid delivery tubular (140) to the exterior of the fluid delivery tubular (140) from a first end (46) of the interval (48) to a second end (44) of the interval (48) to progressively treat the interval (48) of the wellbore (32).

摘要： Sensors are attached directly to portions of the sand screen of a gravel packing assembly, with connectors to the sensors run through elements of the screen that are hollow for that purpose. The hollow element can be the trapezoidal wire that is circumferentially wrapped to form the outer screen or one of the outer spacers used to provide a stand-off of the wire from the underlying tubing. Sensors can detect such conditions as pressure, temperature, flow rate, density, etc., and can provide real-time information on the effectiveness of gravel placement during packing and on well conditions during production.

摘要： The present invention provides a self-contained sensor module for use in a subterranean well that has a well transmitter or a well receiver associated therewith. In one embodiment, the sensor module comprises a housing, a signal receiver, a parameter sensor, an electronic control assembly, and a parameter transmitter; the receiver, sensor, control assembly and transmitter are all contained within the housing. The housing has a size that allows the module to be positioned within a formation about the well or in an annulus between a casing positioned within the well and an outer diameter of the well. The signal receiver is configured to receive a signal from the well transmitter, while the parameter sensor is configured to sense a physical parameter of an environment surrounding the sensor module within the well. The electronic control assembly is coupled to both the signal receiver and the parameter sensor, and is configured to convert the physical parameter to a data signal. The parameter transmitter is coupled to the electronic control assembly and is configured to transmit the data signal to the well receiver.

摘要： A non-flashing fluid sampler for use in obtaining a well fluid sample. The sampler comprises a body defining a first chamber, a second chamber, a third chamber and a sampling port therein. The sampling port is in communication with the first chamber and with an outside zone outside the body. The second and third chambers are initially isolated from one another by a control valve. Upon activating the control valve, fluid may flow from the second chamber to the third chamber through a flow restriction. An extendable floating piston is disposed between the first and second chambers, and the floating piston defines a variable volume therein. An initial amount of well fluid flows into the variable volume, thus trapping dirty fluid, and subsequently, a well fluid sample is flowed into the first chamber. An isolation valve is provided for allowing hydrostatic pressure into the sampler after the fluid sample has been taken. Check valves prevent outward fluid flow from the sampler and thereby trap die hydrostatic pressure therein. Methods of use of the sampling apparatus are also disclosed.
