Abstract

The invention discloses a self-floating-type external-force-drift-prevention self-cleaning electronic single-point measuring instrument. The self-floating-type external-force-drift-prevention self-cleaning electronic single-point measuring instrument comprises a wire, a grasping and guiding rod and a connecting rod. The self-floating-type external-force-drift-prevention self-cleaning electronic single-point measuring instrument has the beneficial effects that under the action of a valve moving plate, external sandstone is filtered to prevent the external sandstone from entering a flow-guidingsleeve with the impact of the water flow, under the action of the downward arc shape of the lower surface of the sleeve, the sandstone can be washed away to avoid blockage, and under the action of a high friction wheel-rotating device, when the high friction wheel-rotating device rotates at a high speed, the vertical inclination of a rotating blade can be adjusted automatically, and the rotating speed is changed; and under the action of an attachment separating device, the water flow speed can be ensured while self-cleaning is carried out. Under the action of the device rotation, the externalforce can be resisted, and deviation is avoided. Under the action of a vertical flow plate, compactors can be staggered to extend to compact the sandstone on the inner surface of an oil well; and meanwhile, under the action of an inner concave surface, the falling sandstone can be collected and then is compacted on the inner wall, and the situation that rising of the instrument is obstructed due to the sandstone is avoided while vertical falling of the instrument is ensured.

Description

technical field [0001] The invention relates to the field of well detection, in particular to a self-floating electronic single-point measuring instrument that resists external drift and self-cleaning. Background technique [0002] The electronic single-point inclinometer is the most common instrument in the current petroleum directional drilling engineering. It can be used in both large and small holes. Realize orientation, twist orientation, and prevent well collision. [0003] However, during the drilling and production of oil wells, after the instrument is put in, it is easy to be impacted by the water layer deep in the oil well, causing a large friction force between it and the water, and the friction force is easy to cause the instrument to appear in the process of falling. Drift, the deviation caused by the drift will increase with time, which will lead to errors in the well deviation measurement of the oil well. At the same time, the inner wall of the oil well conta...
