摘要： In one aspect of the invention, a downhole tool string component comprises a tubular body with a first and a second tool joint adapted to connect to adjacent tool string components, and a central bore adapted to pass drilling mud between the joints. A sleeve circumferentially disposed about an outer surface of the tubular body. The sleeve is rigidly attached to the outer surface at first and second sleeve ends and forming at least three stabilizer blades. A nuclear source and at least one nuclear detector are disposed within a gap formed between the inner surface of the sleeve and the outer surface of the tubular body.

摘要： In one aspect of the invention a downhole tool string component has a segmented sleeve slideably attached over the exterior of a mandrel which is adapted for connection to an adjacent tool string component. An end of the sleeve is abutted against a shoulder element of the mandrel and an opposite end of the sleeve is axially loaded by a threaded element attached to the mandrel. The sleeve comprises at least one sleeve segment with an engagement end comprising at least one axial anti-rotation assembly adapted to transfer torque to an adjacent sleeve segment, the shoulder element, or the threaded element.

摘要： In one aspect of the present invention, a downhole tool string component has a first and second threaded end on a mandrel, the first threaded end attached to a first sleeve and the second threaded end attached to a second sleeve. An intermediate sleeve assembly is disposed circumferentially around the mandrel and intermediate the first and second threaded ends, and the intermediate sleeve assembly is primarily isolated from stress of the first or second sleeve.
