摘要： A downhole acoustic measurement tool includes at least one transmitter longitudinally spaced apart from a non-uniformly spaced longitudinal array of acoustic receivers. The array has a non-uniform spacing such that a first spacing between a first pair of consecutive acoustic receivers in the array is not equal to a second spacing between a second pair of consecutive acoustic receivers in the array. Non-uniform spacing of the receivers in the array reduces aliasing when the received waveforms are processed, for example, to obtain semblance data.

摘要： Thermally stable diamond bonded construction comprise a diamond bonded body including a thermally stable region, comprising a plurality of diamond grains bonded together by a reaction product of the diamond grains with a reactant such as Si, and a polycrystalline diamond region, comprising intercrystalline bonded diamond and a catalyst material. The body further comprises a ceramic compound formed by reaction of an Nb, Zr, Ti, or Mo getter material with a gaseous element generated during HPHT sintering of the diamond bonded body. The diamond bonded body may comprise from 0.1 to 15 percent by weight of the ceramic compound. The diamond bonded body can be formed during a single HPHT process operated at different temperatures when the reactant has a melting temperature above the catalyst material. The construction may include a metallic substrate attached to the diamond bonded body to facilitate use as a wear or cutting element.

摘要： A method (200) for forming a borehole image includes fitting logging sensor measurements residing in each of a plurality of azimuthal windows (Wk) with corresponding mathematical fitting functions (302,322). The functions (302,322) may then be evaluated at one or more corresponding azimuthal positions to obtain at least one sector value for each of the azimuthal windows. A two dimensional borehole image may be formed by repeating the procedure at multiple measured depths in the borehole (40).

摘要： A directional resistivity tool (100) includes a pair of transmitters (T1,T2) deployed between at least one pair of receivers (R1,R2). Each of the transmitters and receivers (T1,T2; R1,R2) preferably includes collocated z-mode and x-mode antennae (122,124; 132,134; 142,144). Exemplary embodiments may further include additional receivers (R3,R4,R5,R6), for example, additional pairs of receivers deployed axially about the transmitters or one or more deep reading receivers (R3,R4,R5) deployed on one axial end of the transmitters (T1,T2). Tools (100) in accordance with the invention enable directional resistivity measurements to be acquired at multiple depths of investigation using fewer transmitter firings than conventional tools (50).

摘要： A logging while drilling tool (100) includes a directional resistivity antenna and an antenna shield (150,250,350,450,550). The shield (150,250,350,450,550) has at least one slot (160) having at least one electrically open end (165) formed therein. The antenna shield (150,250,350,450,550) may include a base portion (170,370) and a plurality of spaced apart fingers (172,372) extending away from the base portion (170,370) such that the finger ends (174,374) are electrically isolated from the tool body (110) and from one another. The antenna shield (550) may alternatively include a plurality of spaced apart plates (570) that are electrically isolated from the tool body (110) and from one another. These antenna shields (150,250,350,450,550) have been found to provide suitable physical protection for sensitive antenna components while at the same time being substantially transparent to both z-mode and x-mode electromagnetic waves.
