摘要： A method for removing cyclic noise from a borehole image includes transforming the image into the frequency domain using a two-dimensional (2-D) transform (e.g., using a discrete cosine transform). The cyclic noise components (peaks) are removed from the transformed image which is then inverse transformed back into the spatial domain using an inverse 2-D transform to obtain a corrected image. An automated method enables the cyclic peaks to be identified and removed from the borehole image via downhole processing.

摘要： A method for removing cyclic noise from a borehole image includes transforming the image into the frequency domain using a two-dimensional (2-D) Fourier Transform, removing cyclic noise components from the transformed image, and inverse transforming the image back into the spatial domain using an inverse 2-D Fourier Transform. The cyclic noise component may also be isolated by subtracting the corrected image from the original image or by removing all non-cyclic noise components from the transformed image prior to inverse transforming. Removal of the cyclic noise from a borehole image tends to enable the identification of borehole features and provide for improved accuracy in formation parameter evaluation. Evaluation of the cyclic noise component may also enable the source of the noise to be identified and mitigated.

摘要： A downhole measurement tool includes at least one regular receiver and at least one reference receiver externally deployed on a tool body. The reference receiver is configured to be acoustically isolated from the borehole, for example, via an isolation structure including a high-impedance cap and a low-impedance gap. The reference receiver may be deployed in a linear array with the regular receiver(s) and may be substantially identical to the regular receiver(s) such that it has substantially the same sensitivity to tool mode signals and internal drilling noise as do the regular receivers. Received waveforms may be processed so as to remove tool mode arrivals and/or drilling noise.

摘要： A method for controlling furnace pressure of a continuous annealing furnace is disclosed. The method comprises detecting a coal gas flow volume and an air flow volume in each section by use of a coal gas flow volume detector and an air flow volume detector disposed in each section of a continuous annealing furnace, respectively, adding up the coal gas flow volume detected in each section to obtain a total input coal gas flow volume; adding up the air flow volume detected in each section to obtain a total input air flow volume, and calculating a pre-combustion gas pressure in the furnace based on the total input coal gas flow volume and the total input air flow volume; detecting compositions of the coal gas and a ratio of the coal gas to the air by use of a composition detector; detecting a pre-combustion gas temperature in the furnace by use of a thermocouple; predicting post-combustion gas compositions and a total gas volume based on chemical combustion reaction equations and based on the total input coal gas flow volume, the total input air flow volume, the coal gas compositions and the ratio of the coal gas to the air; igniting the coal gas and the air in the furnace; and detecting a post-combustion gas temperature in the furnace by use of a thermocouple; calculating a post-combustion gas pressure in the furnace based on the pre-combustion gas pressure in the furnace, pre-combustion gas temperature in the furnace and the post-combustion gas temperature in the furnace; and calculating an opening degree for an exhaust gas fan based on the pre-combustion gas pressure in the furnace and the post-combustion gas pressure in the furnace and by use of a gas increment pass algorithm, and using the opening degree to control the exhaust gas fan.
