Abstract

The invention discloses a high-temperature vertical well inclinometer, and aims to solve the problems of long measurement period, low measurement efficiency and inconvenience in maintenance caused by complex structure, large size and low data uploading speed of an inclinometer in the prior art. The inclinometer comprises an inclinometer body; the inclinometer body comprises a pulse generator module, a hydraulic mechanism module and a main control circuit module; the main control circuit module obtains well deviation parameters and converts the well deviation parameters into control signals to enable the hydraulic mechanism module and the pulse generator module to do axial reciprocating motion to generate different pulse pressure waves, and then the different pulse pressure waves are decoded through a ground differential pressure sensor, a decoder and the like to obtain underground parameters. The inclinometer body is modularly designed, so that the inclinometer is small in size, light in weight and convenient to manufacture and assemble; the invention has the advantages of simple structure, short length, low power consumption, high decoding rate and fast data transmission; the device is suitable for high-temperature and high-pressure environments, the measurement period is shortened, the measurement efficiency is improved, and the working time is prolonged.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling engineering, in particular to a high temperature vertical well inclinometer. Background technique [0002] With the rapid development of geological exploration technology, in the early stage of oil and gas exploration and development and geological coring, the construction party pays special attention to construction technology and drilling cycle. There are more and more special and complex wells such as high temperature and high pressure wells, and the requirements for wellbore quality are getting higher and higher. The well deviation measurement of these special wells faces great challenges. The well deviation measurement and control of vertical wells are becoming more and more important. Forcing conventional measurement methods to improve quality and speed. [0003] At present, conventional inclinometers have complex structures, large volumes, and slow data upload speeds, resultin...
