摘要： A system can be provided that can include a measurement tool that can be coupled to a conveyance mechanism for positioning the measurement tool downhole in a wellbore. The wellbore can be encased by a tubular. The system can further include a vibration-inducing device that can cause the tubular to vibrate. Additionally, the system can include an interferometer coupled to the measurement tool for detecting the vibration in the tubular. The system can further generate data useable to determine at least one status of the tubular and at least one status of a cement layer. The cement layer can be positioned between the tubular and a subterranean formation surrounding the wellbore.

摘要： A device for generating pressure waves in a well or a wellbore is described. The device includes a housing containing an impact-generating mechanism for generating the pressure waves and a connector for connecting the housing to a conveyor for transporting the device to any desired location within the well or the wellbore. The device may be used for a number of downhole applications such as cleaning perforations, fracturing processes, vibration of a casing to prevent fluid flow in a cemented annulus, hydraulic jar operations for freeing stuck downhole objects, generating data to optimize pumping parameters and as an enhancement to percussion drilling techniques.

摘要： A method may include obtaining drilling surface parameter data regarding one or more drilling parameters during a drilling operation for a wellbore. The method may further include obtaining geological data regarding one or more formations within a subsurface of the wellbore. The method may further include obtaining vibration data regarding various drilling operations for various wellbores. The method may further include determining a predicted vibration value of a bottomhole assembly in the drilling operation using a machine-learning model, the drilling surface parameter data, the geological data, the vibration data, and a rate of penetration (ROP) value regarding the bottomhole assembly. The method may further include determining an adjusted ROP value regarding the bottomhole assembly using the predicted vibration value and the ROP value. The method may further include transmitting a command to update the drilling operation based on the adjusted ROP value.

摘要： The invention discloses a pipeline descaling and rock stratum fracturing device based on electro-hydraulic pulse shock waves, comprising a ground low-voltage control device, a transmission cable and an electro-hydraulic pulse shock wave transmitter. The invention generates available high-strength shock waves with repetition frequency to bombard a specific position of the pipeline or rock stratum so as to achieve the effect of pipeline descaling and rock stratum fracturing; the breakdown field strength of the liquid gap can be effectively reduced to improve the conversion efficiency of the electrical energy to the mechanical energy of the electro-hydraulic pulse shock wave so as to obtain a high-strength electro-hydraulic pulse shock wave; the transmitting cavity adopts a parabolic focusing cavity, and through refraction and reflection of the rotating parabolic cavity, the shock wave is focused in a preset direction and radiates outwards to act on the pipeline dirt or rock stratum while ensuring that the shock wave has no longitudinal component and does not will not damage the liquid within the pipeline and the pipeline sheath, so that the effect of pipeline descaling or rock stratum fracturing is improved after focusing. The invention has the advantages of effectively removing the pipeline dirt, fracturing the rock stratum and improving the permeability as well as high reliability, environmental friendliness and low cost.

摘要： A drill string is comprised of a vibration damping drill pipe section, made of a material such as aluminum alloy, titanium, composite material, or ductile iron, for example, and another drill pipe section made of a different material, such as conventional steel. The vibration damping drill pipe section may be place in any desired location, such as near sensitive equipment, such as a bottom hole assembly. Additional vibration damping sections may be interspersed with conventional drill pipe. The vibration damping drill pipe helps to reduce vibration experienced by the drill string during drilling, particularly torsional and lateral vibration.

摘要： A drilling system includes a drill string extendable into a wellbore penetrating a subterranean formation. The subterranean formation exhibits a resonant frequency and a drill bit is coupled to a distal end of the drill string. A vibration sub is positioned within the drill string adjacent the drill bit for generating vibration stress waves at the drill bit, and the vibration stress waves exhibit a vibration frequency that approximates the resonant frequency.

摘要： A downhole tool is disclosed herein that has an inlet for receiving fluid into a housing of the downhole tool. The downhole tool further includes a vibratory apparatus at least partially disposed within the housing of the downhole tool, the vibratory apparatus having an operational flow path disposed therein to operate the vibratory apparatus when fluid flowing through the operational flow path is above a predetermined pressure. Furthermore, the downhole tool has a bypass passageway disposed in the housing for providing an additional flow path for fluid through the downhole tool to prevent fluid from reaching the predetermined pressure in the operational flow path of the vibratory apparatus, the bypass passageway selectively blockable such that fluid in the operational flow path is increased above the predetermined pressure to activate the vibratory apparatus when the bypass passageway is blocked. A method of using the downhole tool is also disclosed.

摘要： A method, system, and electrode assembly are disclosed that maximizes the lifetime of electrodes for high energy electrical discharges in water by arranging the electrodes in concentric rings or a stack of concentric rings. The radii and the thickness of the ring electrodes are optimized for electrical reliability, low jitter, and minimal erosion. In one embodiment, the electrode assembly is configured to be disposed in a subterranean dielectric medium, receive an electric current pulse having a length of time greater than 100 microseconds, and form an electric arc between the first electrode and the second electrode, thereby producing a pressure pulse axially away from the insulator.
