Elaboration of receiver unit of Azimuth acoustic correction system

Abstract

The paper describes a method of azimuth acoustic correction of an inclinometer for oil and gas wells in high-latitude areas where usual gyroscopic and ferromagnetic sensors are inefficient because of significant errors. An embodiment of the method and options for units are presented. The focus is on a scheme of acoustic receiver unit of the system and it main functions such as downhole acoustic signal recording and data transmitting from downhole to wellhead. A comparison of analog and digital variants for data transmission is presented and justification for selecting the analog variant as preferable is given. The electronic scheme of the receiver unit as the preferable variant is described and estimates of operability of the unit are given.
