    摘要： Systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining an operational state of one or more solenoids of well equipment are disclosed. A characterization and diagnosis apparatus can determine characterization measurements for a solenoid. The characterization measurements can be obtained during a characterization mode of the solenoid based on drive voltages and temperatures. The characterization and diagnosis apparatus can determine sampled measurements for the solenoid during an operational diagnosis mode of the well equipment. The characterization and diagnosis apparatus can compare the characterization measurements to the sampled measurements to diagnose the operational state of the solenoid.

    摘要： Lateral access control in downhole window joint is provided via a window joint. The window joint includes an interior cavity with a first end and a second end opposite to the first end, a first opening defined at the first end, and a lateral opening through a wall of the window joint and into the interior cavity between the first end and the second end. The window joint also includes a deflector where, in a first state, the deflector permits access between the first end and the second end and, in a second state, the deflector blocks access between the first end and the second end and permits access between the first end and the lateral opening by deflecting an object travelling through the lateral opening. The window joint also includes an access control system configured to transition the deflector between the first state and the second state.

    摘要： A vibrational disfunction machine learning model trainer trains a vibrational disfunction classifier to identify one or more types of vibrational disfunction, or normal drilling, based on measurements of at least one of displacement, velocity, acceleration, angular displacement, angular velocity, and angular acceleration acquired for the drill bit. The vibrational disfunction machine learning model trainer trains the algorithm based on data sets corresponding to characteristic behavior for one or more types of vibrational disfunction and normal drilling. The vibrational disfunction classifier operates in real time, and can operate at the drill bit and communicate vibrational disfunction identification in real time, allowing mitigation of vibrational disfunction through adjustment of drilling parameters.

    摘要： A downhole flow control device is used to control the production of formation fluids while using flow of the formation fluids to drive a turbine. Flow through a turbine chamber is optimized using a chamber insert that cooperatively defines a reduced chamber volume with the turbine chamber. The chamber insert includes an overhead portion defining a ceiling over the turbine and an arcuate portion contiguous with an arcuate portion of the turbine chamber. The baffle is perforated to allow some flow to exit the reduced chamber volume to a bypass port in a cavity radially outwardly thereof. The turbine may be used for any suitable downhole application, such as an inflow control device or to generate electrical power.
