The "Advanced Logging Technology and Equipment" project passed the acceptance of the Ministry of Science and Technology

[China Instrument Network Instrument R&D] Recently, the “Advanced Logging Technology and Equipment” project of the 863 Program, led by PetroChina Logging Co., Ltd., passed the acceptance of the expert group of the Ministry of Science and Technology in Beijing. The expert group believes that the research results of the project are rich and provide new means for solving oil and gas evaluations in complex and unconventional reservoirs.

As one of the national 863 project resource and environmental technology field theme items, "advanced logging technology and equipment" includes research on formation mineral logging technology, low frequency localized resistivity logging method and instrumentation, development of radar imaging logging prototype, and downhole nuclear magnetic field. The Resonance Fluid Analysis System developed four topics, led by China National Petroleum Logging Corporation, and jointly tackled by Sinopec North China Petroleum Bureau and China University of Petroleum (Beijing).
Since the establishment of the project in 2013, the project team has tried harder and harder, pioneered and innovated, and has broken through high-accuracy and low-drift full-spectrum acquisitions, continuous inversion of formation resistivity, evaluation of wellbore anomalies, downhole high-power signal transmissions, and online rapid multidimensional pulse sequences. Eight key technologies were successfully developed, such as formation mineral logging tools, low-frequency localized resistivity logging tools, radar imaging logging tools, and downhole NMR fluid analysis systems, four sets of prototypes and supporting acquisition and processing interpretation software, and two models were established. Completion facilities for scale wells and one standard well, accumulatively applied for 23 national invention patents, obtained 2 software copyrights, published 21 papers, formulated 1 industry standard, and formed nuclear, electric, and radar measurements. Wells and NMR logging four innovative R&D teams have played a leading and demonstration role in the further development of complex lithologies and unconventional oil and gas well logging technologies and new equipment.
