摘要： An apparatus for nuclear logging is presented. In accordance with the present invention, nuclear detectors and electronic components are all mounted in chambers within the sub wall with covers being removably attached to the chambers. A single bus for delivering both power and signals extends through the sub wall between either end of the tool. This bus terminates at a modular ring connector positioned on each tool end. This tool construction (including sub wall mounted sensors and electronics, single power and signal bus, and ring connectors) is also well suited for other formation evaluation tools used in measurement-while-drilling applications.

摘要： A measurement-while-drilling (MWD) density tool is provided which incorporates a single gamma ray source and a pair of longitudinally displaced and mutually aligned detector assemblies (i.e., dual scintillation counters). A nuclear source is mounted in a pocket in the sub wall and partially surrounded by gamma ray shielding. The subwall section adjacent the source is expanded radially so as to define a lobe which displaces mud thus reducing borehole and mudcake effects. The two detector assemblies are mounted within a cavity or hatch formed in the subwall and enclosed by a detector hatch cover under ambient pressure. The detector assemblies are fixedly spaced from the source and are also partially surrounded by gamma ray shielding to provide good formation response. The hatch cover is secured to the sub by bolts and contains radiation transparent windows therethrough in alignment with the detector assemblies. A threaded-on fluid displacement sleeve is positioned on the sub and over the detector hatch cover. This sleeve has several important functions including the displacement of borehole fluids, reducing mudcaking which might have an adverse effect on the measurement and maintaining a relatively constant formatio to detector distance. The sleeve is full gage (with respect to the borehole diameter) and includes radiation transparent windows that are positioned over the hatch cover windows in a manner which optimizes the response of the tool. The sleeve includes blades which are configured such as to provide adequate flow area in the annulus between the density sub and formation wall.

摘要： An accelerometer has a main body in combination with one or more Bragg grating sensors respectively arranged along one or more axes. The main body has a mass that responds to an acceleration, for providing a force having a component in one or more axes. The Bragg grating sensor means responds to the force, and further responds to an optical signal, for providing a Bragg grating sensor signal containing information about the acceleration respectively in one or more axes. The one or more axes may include orthogonal axes such as the X, Y and Z Euclidian axes. In one embodiment, the main body includes a proof mass and a pair of flexure disks, each having an inner ring, an outer ring, and radial splines connecting the inner ring and the outer ring. The proof mass is slidably arranged between the flexure disks. The Bragg grating means has an optical fiber and a Bragg grating sensor arranged therein. A first end of the Bragg grating sensor is fixedly coupled by a first ferrule to the proof mass. A second end of the Bragg grating sensor is fixedly coupled by a second ferrule to a housing of the accelerometer. In operation, the compression or stretching of a Bragg grating sensor causes a wavelength shift in the optical signal that contains information about the acceleration and that is sensed by a detector.

摘要： Lengths of coiled tubing have sensor carrier elements mounted therebetween such that a plurality of sensor carrier elements are positioned along a length of coiled tubing. Each sensor carrier element carriers a sensor implemented with one or more intrinsic fiber optic sensor elements positioned therein for measuring one or more parameters in an environment. The intrinsic fiber optic sensor elements are multiplexed on one or more optical fibers along the length of the coiled tubing thereby forming a length of coiled tubing having a plurality of spaced apart sensors. The optical fiber or fibers positioned along the length of the coiled tubing are positioned in a fiber carrier which protects the fiber or fibers from the harsh environment. The fiber carrier may be interconnected to each of the sensors to isolate the fibers from the harsh environment. Each sensor carrier element provides the desired transmission of environmental conditions to the sensor carried therein, such as fluid communication, heat transmission, acoustic signal transmission, etc., such that the sensor contained in the sensor carrier element is responsive to a parameter of interest. A plurality of sensors may be serially connected to one another for distributed sensing of one or more parameters at multiple locations along the length of the coiled tubing. The sensor carrier elements are interconnected to the coiled tubing to provide a reliable and secure seal therebetween. The sensor carrier elements are configured to maintain the structural integrity of the coiled tubing while at the same time carrying a sensor implemented with an intrinsic fiber optic sensor element. The sensor carrier elements may be interconnected to the coiled tubing by press fit engagement, welding, fusion, and/or any other suitable method for providing a secure connection between the coiled tubing and the sensor carrier elements.
