SYSTEM AND METHOD FOR DETERMINING THE INCLINATION OF A WELLBORE

摘要

A well survey system comprising an electronic survey tool for determining t he inclination of a wellbore is disclosed herein with methods of use. In some embodiments, the electronic survey tool includes an electrolytic tilt sensor adapted to measure a first tilt angle within a first plane and a second tilt angle within a second plane of the electrolytic tilt sensor. The electronic survey tool also includes a system processor for determining the inclination of the wellbore based on the first and second tilt angles. A s such, a drop-in replacement and improvement on a mechanical critical vertical drift (CVD) to ol is provided herein. The electronic survey tool of the present invention also improves upon and overcomes the disadvantages of prior art electronic survey cools. Due to the stability of the improved survey tool over time and with changes in ambient temperatur e, for example, the improved survey tool does not require periodic recalibration or correction of measurements for errors and biases.
