The utility model relates to the technical field of manufacturing of petroleum drilling and production equipment, and discloses a high-low pressure device for petroleum drilling and production, which comprises an instrument assembly body, two observation outlets are arranged at the top of the instrument assembly body, and two pressure gauges are respectively mounted on the two observation outlets. The two pressure gauges are respectively a 0-10MPa (metric-inch) anti-seismic pressure gauge and a 0-100MPa (metric-inch) anti-seismic pressure gauge, so that the working states in different pressure ranges can be monitored in real time, and the stability and the safety in the drilling process are ensured. By arranging the device, the pressure can be monitored and adjusted in real time, and the stability and safety of the drilling process are ensured; the design of the buffer and the stop valve effectively prevents the instrument from being damaged, prolongs the service life of equipment, reduces the maintenance cost, improves the working efficiency, reduces the use cost, can randomly rotate the observation direction of the pressure gauge, can quickly and conveniently observe the pressure in the equipment or a pipeline, and improves the safety and reliability of the operation of a drill rod well.

This utility model discloses an electric bridge side drilling tool, including a tool frame, which includes a suspension frame and a support frame. The suspension frame has a downward-facing hanging part, and the support frame is fixed to the right side of the suspension frame. A drive and walking component is mounted on the suspension frame, and a drilling component is mounted on the support frame. A support base plate is connected to the bottom of the support frame, and the drilling component is mounted on the support base plate. This tool eliminates the need for additional personnel to assist in its movement, saving manpower and improving its mobility. It also eliminates the need for construction personnel to perform high-altitude drilling operations outside the bridge crash barrier, reducing construction costs and risks. Furthermore, it ensures uniform height, depth, and levelness of the drilling, guaranteeing the quality of the drilling and the installation effect of the support structure. This effectively saves drilling time and improves the construction progress of the pipe box support.

This invention belongs to the field of petroleum drilling technology and relates to a telescopic grinding shoe composite stacked PDC drill bit, comprising a drill bit body, a grinding shoe column, stacked PDC cutter wings, and a control sub. The stacked PDC cutter wings are fixed to the bottom of the drill bit body and are composed of multiple single-layer PDC cutter wings interlocked. The drill bit body is connected to the control sub via a connector at the top. The drill bit body is provided with a chip removal groove, and several nozzles are distributed at the bottom of the drill bit body. Gauge holders are distributed on the sides of the drill bit body. The grinding shoe column is disposed within the chip removal groove and is arranged along the axial direction of the drill bit body. A power unit drives the grinding shoe column to extend and retract along its axial direction. The telescopic grinding shoe composite stacked PDC drill bit proposed in this invention can realize the disposal and self-regeneration of worn PDC drill bit structures, thereby shortening the drilling cycle and reducing drilling costs.
