30 teaching professors, undergraduate, graduate and post-graduate students from the Department of Geophysics, Perm State University (PSU) and the Department of Field Geophysics, Chinese Petroleum University (Qingdao) took part in a joint Russian-Chinese seminar on developing while drilling technologies.
The seminar regarded the problem of Logging While Drilling (LWD) technologies, addressing the issue of radioactivity. World leaders in LWD technologies are American companies that hold the dominant share of the LWD market in Russia, China and other oil-producing countries. Among the most significant Russian developers of LWD technologies is LLC NPP Energia (Tver). In recent years, Chinese geophysicists, and China Petroleum University (Qingdao), in particular, have made significant progress in this direction.
Addressing the audience, Valery Kataev, Dean of the Faculty of Geology, PSU, stressed the importance of Chinese and Russian universities’ cooperation. On behalf NPP Energia, the research was presented by leading specialists Alexander Panikorovsky, PSU graduate student, and Grigory Evgeniev. The scientists chose to speak about the progress of technologies used at measuring density and neutron porosity while drilling, presenting the outcomes of their application in comparison with foreign analogues, testifying for their original prospects.
Yu Huavei, Associate Professor, Department of Logging, China University of Petroleum, highlighted the development of neutron gamma-ray and density gamma-ray logging in relation to the impact on human health and the environment. His colleague Qian Chen presented a research on visualization of azimuthal gamma and density Logging While Drilling, while Professor Shao Tsairui provided a final report.
“The Seminar participants discussed the problem of effective development of hydrocarbon deposits, which is quite urgent for the oil business, drilling of horizontal wells in the optimal zones of oil and gas reservoirs, in particular. The issues of increasing the accuracy of measurements of density and porosity of rocks, modeling and registering the propagation field of radioactive radiation by sector groups of sensors, as well as the use of non-chemical sources of radiation were discussed. Obtaining new scientific and technical information, followed by broad discussion have significantly widened our visions,”noted Professor Valentin Gershanok, Department of Geophysics, PSU.
Summing up, Professor Gennady Tsvetkov, Department of Geophysics, PSU acknowledged the level of presented reports, thanked the authors for their dedication and the audience for the attention. He also expressed hope for a future joint department collaboration as a single lab, contributing to the progress of Logging While Drilling technologies.
