Abstract

The invention belongs to the field of prospecting and measurement, in particularly to a storage logging system. The storage logging system comprises a ground system and an underground instrument; a logging system is arranged in the underground instrument; the logging system comprises a storage, an azimuth signal acquiring module and a borehole diameter signal acquiring module which are all connected with a main control module; the azimuth signal acquiring module is connected with an azimuth sensor; the borehole diameter signal acquiring module is connected with a borehole diameter sensor; and a power supply respectively supplies power to the main control module, the storage, the azimuth signal acquiring module and the borehole diameter signal acquiring module by a power supply management module. The storage logging system breaks through the conventional thinking of transmitting logging data by a cable and solves the logging problem under the difficult conditions by adopting the storage instrument.

Description

technical field [0001] The invention belongs to the field of surveying and surveying, in particular to a storage logging system. Background technique [0002] At present, the measurement methods of most downhole instruments in oil well logging are to convert non-electrical signals into electrical signals through sensors, and after processing, they are uploaded to the ground by cables for decoding, which can be interpreted by ground technicians. Using wired methods to transmit data, there are problems such as bulky cables, fragile, susceptible to electromagnetic interference, and long-distance signal transmission. Especially in high-deviation wells and high-pressure wells, it is impossible to lower the logging instrument to the bottom of the well. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a storage logging system, which breaks through the thinking of conventional cable transmission of logging ...
