摘要： A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.

摘要： A rotary steerable drilling system includes a collar, a drill bit, and a bit shaft connecting the drill bit to the collar. The bit shaft is coupled to the collar through a joint capable of transmitting a torque from the collar to the bit shaft and is swingable with respect to the collar around the joint. The system, further includes first eccentric wheel and second eccentric wheel coupled to the bit shaft and rotatable to swing the bit shaft with respect to the collar around the joint to change a drilling direction, a controller for controlling the first eccentric wheel and second eccentric wheel to harmoniously rotate such that the swing of the bit shaft substantially compensates rotation of the bit shaft, and an active stabilizer mounted on the bit shaft and capable of pushing the bit shaft to deviate to cause a lateral displacement and a tilt angle of the drill bit.

摘要： A downhole measurement tool configured to be run through a bore includes a source and a 3-component receiver. The source is configured to emit a source signal, which may be a compressional or a shear wave, into a volume of material surrounding the bore. The source signal propagates through the volume of material surrounding the bore and reflects off of features disposed within the volume of material surrounding the bore. The three-component receiver includes a first element, a second element, and a third element. The first element is oriented in a first plane, orthogonal to an axis of the bore, and receives a first component of the set of reflections of the source signal. The second element is oriented in the first plane, orthogonal to the first element, and receives a second component of the set of reflections of the source signal. The third element is oriented parallel to the axis and receives a third component of the set of reflections of the source signal.
