摘要： The logging tool (55) of this invention includes a transmitter conveyed on a drilling collar (90) for exciting a quadruple signal in a borehole (26) being drilled by a drill bit and a receiver for receiving the signal. The transmitter (105) is operated at a frequency below the cut-off frequency of the quadruple collar mode. The received signal consists primarily of the formation quadruple mode which, at low frequencies, has a velocity that approaches the formation shear velocity. The transmitter, in one embodiment, consists of eight equal sectors (101 et al) of a piezoelectric cylinder mounted on the rim of the drilling collar. The value of the cut-off frequency is primarily dependent on the thickness of the drilling collar. Alternatively, the transmitter may be operated to produce both the collar mode and the formation mode and a processor may be used to filter out the collar mode.

摘要： A method and apparatus for assessing the permeability of a subterranean formation (6) and the hydrocarbon and/or water content of the formation. The method includes emitting (12) an acoustic signal, such as a Stoneley wave into the formation and sending (20) an electro-magnetic pulse into the formation.

摘要： A radial shear velocity profile of an earth formation is obtained by using dipole and/or cross-dipole measurements. The non-uniqueness in the inversion is addressed by using a constraint based on the fact that high-frequency dipole shear waves are mostly sensitive to the near-borehole shear velocity.

摘要： Directional acoustic measurements made in the borehole are used for imaging a near-borehole geological formation structure and determination of its orientation. Four-component cross-dipole data set measured in a deviated borehole in combination with the directionality of the compressional waves in the dipole data give the orientation of bed boundaries crossing the borehole. The low-frequency content (2-3 kHz) of the data allows for imaging the radial extent of the formation structure up to 15m, greatly enhancing the penetration depth as compared to that obtained using conventional monopole compressional-wave data. A combination monopole/dipole arrangement of sources and receivers may also be used for imaging of bed boundaries.
摘要翻译：在井眼中进行的定向声学测量用于对近地层地质构造结构进行成像和确定其取向。在偏斜钻孔中测量的四分量交叉偶极数据集合与偶极数据中的压缩波的方向性相结合给出了穿过钻孔的床边界的取向。数据的低频内容（2-3kHz）允许将地层结构的径向范围成像到15m，与使用常规单极压缩波数据获得的深度相比，大大增强了穿透深度。源和接收器的组合单极/偶极子布置也可用于床边界的成像。

摘要： Stoneley-wave data acquired in the LWD environment are used to characterize/estimate formation permeability. Real-time Stoneley-wave time- delay/slowness and center-frequency /attenuation data are used to indicate/characterize formation permeability even during drilling. The use of stabilizers mounted at the tool ends helps maintain the tool position from severe decentralization, reducing ambiguities in the permeability characterization/estimation.
