Abstract

The invention discloses a drill bit for oil and gas field investigation, which comprises a first casing, a first cavity is arranged inside the first casing, and slide grooves are arranged on opposite side walls of the first cavity, so that The chute communicates with the first cavity, the chute is provided with a first sliding rod, and the two ends of the first sliding rod are fixedly connected with the opposite side walls in the chute, and the upper sleeve of the first sliding rod Two clamping blocks are connected, both ends of the two clamping blocks pass through the hollow groove, two rotating shafts are arranged in the first cavity, and the opposite side walls in the first cavity are provided with There is a groove corresponding to the rotating shaft, and the two ends of the rotating shaft are respectively slidably connected with the two grooves, and a first rotating rod and a second rotating rod are rotationally connected on the two rotating shafts, and the first rotating rod and the second rotating rod are connected in rotation. One end of the second rotating rod is provided with a limit block. The drilling bit for oil and gas field exploration has good shock absorption effect, simple replacement operation, adjustable length, and can meet the investigation work of different depths.

Description

technical field [0001] The invention relates to the technical field of oil and gas field exploration, in particular to a drill bit for oil and gas field exploration. Background technique [0002] Oil and gas fields refer to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs in the same area controlled by a single local structural unit. If there are only oil reservoirs in this local structural area, they are called oil fields, and only gas reservoirs are called gas fields. At present, With the continuous development of oil and gas field exploration technology and the continuous improvement of oil and gas field exploration technology, the requirements for drill bits used in oil and gas field exploration are also getting higher and higher. In the existing technology, the oil and gas field exploration drill bit has the disadvantages of poor shock absorption and buffering effect, cumbersome replacement process, and inability to adjust the length. These problems...
