Abstract: A flowmeter with adjustable reading directions is provided, which includes a flowmeter main body, a casing and a digital display device. The casing is arranged at an outer side of the flowmeter main body; the digital display device is electrically connected with the flowmeter main body so as to read the numerical value of the flowmeter main body. The digital display device is rotatably connected on the casing to adjust the display direction of the numerical value in the digital display device. The digital display device is rotatably connected to the casing, so that the digital display device is equivalent to being indirectly arranged on the flowmeter main body, by rotating the digital display device, the digital display device can align with and face to the working personnel, such that it is convenient for the working personnel to read and record the numerical value.

Abstract: A geosteering method and apparatus, and a storage medium, where the method includes: acquiring first well trajectory information of a target well, and first geological information and second geological information of the target well; determining, by using a plane where a first well trajectory is located as a steering profile, a geological structure line of a first class geological layer corresponding to the first geological information on the steering profile, and determining, by using the geological structure line of the first class geological layer as a reference and based on the second geological information, a geological structure line of a second class geological layer corresponding to the second geological information on the steering profile, so as to obtain a geosteering model of the target well; and using the geosteering model to perform geosteering on actual drilling of the target well.

Abstract: Integrated circuit transmission lines are designed to match elements at opposing ends of the transmission line over a frequency range of interest. By modifying characteristics of the transmission line over the length of the transmission line, from a first end coupled to a first external element to a second end coupled to a second external element, return loss is improved. In various embodiments one or more of the width of the conductors and the distance between adjacent edges of the conductors are modified across the length of the transmission line. In an alternative embodiment, the conductors of the transmission line are segmented with each segment having a length and a width across the segment.
