    摘要： A method for displaying a formation model while drilling a wellbore in the formation includes operating a well logging instrument at a measurement point in the formation along a wellbore while the wellbore is being drilled. Measurement data regarding the formation are obtained from the well logging instrument. An actual orientation of a geological structure is determined from the measurement data. A trajectory of the wellbore is displayed in three dimensions as it is being drilled through the formation. While drilling the wellbore, the geological structure is displayed along the trajectory of the wellbore according to the determined actual orientation of the geological structure. The actual orientation reflects an azimuth angle of planes corresponding to the geological structure. The trajectory of the wellbore is changed in response to displaying the determined actual orientation of the geological structure relative to the trajectory.

    摘要： A method is described for characterizing a subsurface formation with a logging instrument disposed in a borehole penetrating the formation. The logging instrument is equipped with at least a transmitter system and a receiver system. The method entails positioning the logging instrument within the borehole so that the transmitter system and receiver system are disposed in the vicinity of a formation boundary of interest and measuring the azimuthal orientation of the logging instrument. Electromagnetic energy is transmitted into the formation using the transmitter system and signals associated with the transmitted electromagnetic energy are measured using the receiver system. The method further entails determining the relative azimuth of the formation boundary, composing a symmetrized directional measurement using the measured signals and the determined relative boundary azimuth, and determining the relative dip of the formation boundary using the composed directional measurement.

    摘要： A novel on-the-fly data processing technique is useful for extracting signals from the azimuthal variation of the directional measurements acquired by a logging tool within a borehole. The relevant boundary, anisotropy and fracture signals are extracted from the formation response through fitting of the azimuthal variation of the measured voltages to some sinusoidal functions. The orientation of the bedding is also obtained as a result. The extracted directional signals are useful for obtaining boundary distances and making geosteering decisions. Two techniques involving inversion and cross-plotting may be employed, depending on the nature of the boundary. A Graphical User Interface (GUI) is part of a system to facilitate flexible definition of inversion objectives, for improving the inversion results, and for visualization of the formation model as well as inversion measurements.

    摘要： A method for forming EVA comprises the steps of: injection-molding; mold-exchanging; thermosetting molding; product-taking out and mold-returning. An EVA-forming mold structure comprises a first mold assembly and a second mold assembly. The molds, at the same side of the first mold assembly and the second mold assembly, can be exchanged with each other. By such arrangements, after the two material members each with different material characteristics are, respectively, formed in two mold assemblies by injection molding, a thermosetting molding of the two material members will be performed in another mold assembly, thus forming an EVA product with two material characteristics.
