摘要： The disclosure presents processes to locate one or more quantum gravimeters at a hydrocarbon well site, with at least one quantum gravimeter at a surface location. Zero or more additional gravimeters, whether quantum gravimeters or non-quantum gravimeters, can be located downhole a wellbore of the well site. Gravitational data collected from various gravimeters can be analyzed to produce analyzed gravitational parameters and subterranean formation parameters. In some aspects, the gravitational data can be processed, such as by an inversion algorithm or a noise reduction algorithm. The generated results can be used to calibrate non-quantum gravimeters located proximate the well site or downhole the wellbore, identify a depth and direction of a water front, identify the fluid flow of hydrocarbons or water in the subterranean formation, to identify orphaned hydrocarbon reservoirs, or other characteristics of fluid flow or subterranean formation parameters, such as subterranean formation damage.

摘要： A method and a system implementing the method, are disclosed for computing magnetic interferences in measurement while drilling operations, using the retrieved lateral, and axial magnetic interferences of the measurement while drilling downhole tool system. With the disclosed method and system of implementing the method, it can be determined whether the source of the magnetic interference is from the measurement while drilling downhole tool system lateral direction or its axial direction. When magnetic field strength is abnormal, the lateral and axial magnetic interferences are monitored, and then compared against their values before the abnormal magnetic field strength. This way the direction of the magnetic interference is analyzed to eliminate or judge the cause of the interference, and properly guide the measurement while drilling downhole tool system towards its reservoir or well location.

摘要： A method for automatically extracting a tectonic framework of a potential field includes preprocessing gravity potential field data and/or magnetic potential field data from an area to be researched; performing multi-scale and multi-direction edge detection on the preprocessed gravity potential field data and/or magnetic potential field data, and obtaining edges of all scales separately; thinning the calculated edge of each scale into a single pixel width by means of a morphological skeleton algorithm, each point having depth and strength attributes; and obtaining a comprehensive tectonic framework graph and a comprehensive tectonic strength framework graph. A geological structure formed by a control deposit can be identified and qualitatively interpreted, a potential deposit type and attributes of the structure are determined according to prior knowledge of an area to be researched, and different types of tectonic frameworks are screened, thereby achieving target area localization of a metal deposit.

摘要： Example gravity gradiometers are described that utilize high precision resonant optical cavities to measure changes in gravitational forces at high sensitivities. In one example, a sensing system includes a gravity gradiometer and a controller. The gravity gradiometer includes a first mirror and a second mirror arranged to form an optical cavity having an optical axis. The controller is configured to detect, responsive to displacement of at least one of the first mirror and the second mirror along the optical axis, a change in gravity gradient.

摘要： An interactive electronic apparatus and an interactive method thereof are provided. The interactive electronic apparatus includes a main device and a casing. The main device is installed in a containing space of the casing. After the main device establishes a connection with the casing, the casing sends at least one of a first distance between the casing and an object to be sensed by a first distance sensor and a second distance between a bottom portion of the casing and a plane detected by a second distance sensor to the main device. The main device determines an interactive state of interaction with the interactive electronic apparatus based on at least one of a movement information sensed by a gravity sensor, the first distance and the second distance, and sends an interactive signal corresponding to the interactive state.

摘要： An atomic gravimeter device includes one or more lasers and three or more atomic sources. The three or more atomic sources are disposed to launch or drop atoms vertically. The one or more lasers are disposed to generate laser beams that interact with sets of atoms from an atomic source of the three or more atomic sources to measure accelerations of the sets of atoms. A measured value is determined for gravity using interwoven acceleration measurements of the sets of atoms from the three or more atomic sources.

摘要： An airborne gravity-based transducer is disclosed as two embodiments with similar physical structures but different operating principles. The first design includes a particle acting as an active interface characterized by internal vibrations relating to its de Broglie wave, a resonant cavity for trapping the particle, and a phonon-wave source wherein the de Broglie and phonon waves interact over a junction area. In the second design, mechanical displacements between the transducer elements can be monitored through electromechanical transduction.

摘要： Methods, systems, and devices for characterizing a water-flooded zone in an earth formation resulting from injection of water to the formation through an injector well borehole intersecting the formation. The method includes estimating horizontal elongation of the water-flooded zone using a gravity field change in the injector well borehole. Estimating horizontal elongation may include predicting a gravity field change for each of a plurality of model water-flooded zones for the borehole, wherein each model water-flooded zone is an elliptical cylinder having finite height and semi-axes; and fitting the gravity field change to one of the predicted gravity field changes corresponding to one of the plurality of elliptical cylinder model water-flooded zones. The gravity field change may comprise a difference between a first estimated gravity field in the injector well borehole before injection and a second estimated gravity field in the injector well borehole after injection.
