Oil well single point inclinometer based on precession protection and anti-sticking

Abstract

The invention discloses an oil well singlepoint inclinometer based on precession protection and anti-sticking.Theoil well singlepoint inclinometer based on precession protection and anti-sticking structurally comprises a straightening sleeve, a fisher, a protective device, a connector, a buoyancy tank, a probe tube, a lower floating tank, and an indication lamp; the straightening sleeve is fixedly mounted directly above the lower floating tank and is an integrated structure;the left side of the fisher is connected with the outer surface of the lower floating tank, and the protective device is located and movably connected directly below the connector. Theoil well singlepoint inclinometer based on precession protection and anti-stickinghas the beneficial effectsthatthe structure is provided with blades, under the power of water, the blades cooperate with a rotating shaft, the rotating shaft rotates around a flat shaft, so that an instrument is subjected to gravity but does not fall, the phenomenon of falling under the impact force of the water is prevented, a water storage bin is arranged, the water storage bin is isolated from the instrument and is a sealed space, the phenomenon of water soaking in the instrument can be prevented, sticking at the bottom of the instrument can also be prevented under the action of a protective plate, a fixatoris arranged, and the fixture fixes the instrument under the actions ofa floating plate and a drawstring.

Description

technical field [0001] The invention relates to the field of well measurement equipment, in particular to a single-point inclinometer for oil wells based on precession protection and anti-sticking. Background technique [0002] In the 21st century, new energy has become one of the energy sources with the largest demand, and oil is one of the new energy sources. In the process of oil production, it is necessary to drill the oil field, and generally the next oil layer casing is required during the drilling process. In the process of installing the oil layer casing, a single-point inclinometer is needed to measure the data in the well. Thereby, it is convenient to lower the casing in the oil layer. But there are following disadvantages in existing instrument: [0003] During the drilling and production process of oil wells, there will be water layers inside, and the oil wells are deep, and the water layer below will gushes out water, forming blisters. After the instrument is ...

Problems solved by technology

[0003] During the drilling and production process of the oil well, there will be a water layer inside, and the oil well is drilled deeper, and the water layer below will gushes out water, forming blisters. After the instrument is placed on the bottom layer, it will not only be impacted by the water, causing the instrument to test. Tilting, still waiting for the measurement process, the instrument is soaked in water, which affects the measurement results, and the water is mixed with the internal soil, and the internal friction is large, and the instrument is prone to sticking
