摘要： Various triaxial antenna designs having are provided. Some embodiments include a split-z coil that can include two axial coils with saddle coils in the x- and y-directions located therebetween. The split z-coils can function by having a combined magnetic moment similar to that of a single axial coil located between the two parts of the split z-coil. In some examples, the antenna assemblies can include a protrusion or other non-planar structure.

摘要： A logging tool having a plurality of spatially separated antennas is provided and used to make propagation-style measurements in a formation. Tensors are formed using the propagation-style measurements and one or more quantities are computed using the tensors. A formation evaluation is performed using the computed quantities. The formation evaluation determines a formation property or parameter such as horizontal resistivity, vertical resistivity, relative dip, azimuthal dip, bed boundary location, or bed thickness. The computed quantities may include compensated phase shift resistivity, compensated attenuation resistivity, symmetrized phase shift resistivity, symmetrized attenuation resistivity, anti-symmetrized phase shift resistivity, and anti-symmetrized attenuation resistivity. The measurements may be corrected for antenna gain errors and an air calibration may be performed. A zero-dimension inversion may be performed, while drilling, and the determined horizontal resistivity, vertical resistivity, relative dip, and/or azimuthal dip information may be sent to an uphole processor in real-time.

摘要： Se describe una herramienta de registro o perfilaje que tiene una pluralidad de antenas en espacios separados y se utiliza para hacer mediciones en estilo de propagación en una formación. Los tensores se forman utilizando las mediciones en estilo de propagación y se calculan una o más cantidades utilizando los tensores. Se hace una evaluación de la formación utilizando las cantidades calculadas. La evaluación de la formación determina una propiedad o parámetro de la formación, como puede ser la resistividad horizontal, resistividad vertical, el buzamiento relativo, buzamiento acimutal, ubicación del contorno de lecho o el espesor del lecho. Las cantidades calculadas pueden incluir la resistividad del desplazamiento de fase compensada, resistividad de la atenuación compensada, resistividad del desplazamiento de fase simetrizada, resistividad de atenuación simetrizada, resistividad del desplazamiento de fase anti-simetrizada y resistividad de atenuación anti-simetrizada. Las mediciones pueden ser corregidas para los errores de la ganancia de la antena y se puede hacer una calibración del aire. Se puede hacer una inversión de dimensión cero durante la perforación y la información determinada de la resistividad horizontal, la resistividad vertical, el buzamiento relativo y/o buzamiento acimutal puede ser enviada a un procesador arriba del agujero en tiempo real.

摘要： A method to obtain gain-corrected measurements. A measurement tool having one or more arrays is provided, wherein the arrays include two co-located triaxial transmitters and two co-located triaxial receivers. Measurements are obtained using the transmitters and the receivers. Impedance matrices are formed from the obtained measurements and the impedance matrices are combined to provide gain-corrected measurements. The apparatus may alternatively be a while-drilling logging tool having one or more arrays, wherein each array comprises a transmitter, a receiver, and a buck, and wherein the signal received by the receiver is subtracted from the signal received by the buck or vice versa. A slotted shield may be incorporated into either embodiment of the tool. The slots may form one or more island elements. A material is disposed in the slots. The islands and shield body have complementary tapered sides that confine the islands within the shield body.
