A Wired Inclinometer While Drilling

Abstract

The invention discloses a wired drilling inclinometer which comprises a feeding head, a shock absorption steel core sleeve and a sealing joint, wherein a drilling bit is arranged on the surface of the lower side of the feeding head; an inclination guide is arranged on the external surface of the upper side of the drilling bit; an inclination guide alignment nut is arranged on the surface, close to the outer side of the feeding head, of the upper side of the inclination guide; a centering device is arranged on the upper side of the feeding head; a compression resistance cylinder is arranged on the surface of the upper side of the centering device; an extension rod is arranged on the surface of the lower side of the centering device; the centering device internally provided with the shock absorption steel core sleeve is arranged at a connecting part of connecting cylinders, so that the shock is effectively reduced; pulse signal attenuation and errors are greatly reduced; external connection threads of the connecting cylinders are provided with a water-proof sealing ring; a slurry scouring loss is reduced; the drilling is more reliable; a measurement result can be transmitted to the ground accurately in real time, so that eyes wear a pair of glasses; an engineering project is clearer; the command is more suitable; a construction period is shortened; the customer expenditure is reduced.

Description

technical field [0001] The invention belongs to the technical field of measurement while drilling, and in particular relates to a wired inclinometer while drilling. Background technique [0002] Measurement while drilling In the development process of oil and gas field exploration and other development processes, measurements must be carried out after drilling in order to understand the oil and gas content of the formation. For example, in highly deviated wells or even horizontal wells whose inclination exceeds 65 degrees, it is difficult to put the instrument down with a cable , In addition, the well wall is not in good condition, prone to collapse or blockage, and it is difficult to obtain logging data. Therefore, people are thinking that if the logging instrument is placed on the drill bit, the drill bit will have "eyes", and the formation can be obtained while drilling. Various data, this is the measurement while drilling. [0003] Due to the harsh environment, high pre...

Problems solved by technology

[0004] The purpose of the present invention is to provide a wired inclinometer while drilling, in order to solve the problem that the original product proposed in the above-mentioned background technology has a bad environment, great pressure and strong vibration during the drilling process of the drill bit, which leads to measurement results. It is greatly affected by environmental factors, so the stability of LWD tools is difficult to guarantee the accuracy of measurement results
