Dagang developed a successful DG-I compensation neutron logging tool

Recently, the 5700 imaging room of Dagang Oilfield Logging Company upgraded and succeeded the 3700 series lithology density logging tool and digital gamma ray spectrum logging tool.

The development of DG-I compensated neutron logging instrument, while ensuring the technical performance is equal to the technical performance of the ECLIPS-5700 series related instruments, also completes the integrity and support of the complete equipment research of ECLIPS-5700 series radioactive logging instruments. The usability has improved the overall technical strength of the logging company and promoted the localization of the radioactive instrument of the 5700 imaging logging system.

In the development process of DG-I compensation neutron logging instrument, the scientific research personnel independently innovated the safety performance of the instrument, and paid attention to ensuring the safety and stability of loading and unloading the radioactive source under the premise of ensuring the excellent technical performance of the instrument.

By using the ball-receiving positioning device on both sides of the source chamber to control the opening angle of the source box, it can be arbitrarily positioned between 0 and 80 degrees, which changes the conventional fixing method of loading and unloading the radioactive source by artificial paving, so that the radioactive source operation is carried out. It is simpler and more convenient, greatly shortens the operation process, reduces the time of radiation damage to operators and the contact distance of radioactive sources, and provides strong technical support in improving the timeliness and safety quality of radioactive logging.
