Recently, China Petroleum Exploration and Development Research Institute (hereinafter referred to as the Exploration Institute) released the "Insight" logging brand and its first product, the "Mobile Well Site Rock Sample Integrated Continuous Measurement Imaging System CoreLog1.0". The supply and technical development of its dual energy CT equipment were jointly overcome by the Sanying Precision Technology team.
The attending experts believe that this achievement has achieved a core technological breakthrough from 0 to 1, promoting a major technological change in rock physics experiments from indoor to well site, from single point to continuous, and from single attribute to multi parameter collaborative measurement. It is of great significance for efficient exploration and beneficial development of unconventional oil and gas, represented by terrestrial shale oil.
CoreLog1.0 integrated continuous measurement imaging system for mobile wellsite rock samples
CoreLog1.0 is an instrument equipment that realizes the integrated collaborative measurement of "nuclear magnetic laser CT" in the near in-situ state of the well site. It can quickly and accurately measure parameters such as core elements, mineral components, porosity, bulk density, fluid components, and saturation at the first time of core extraction. It achieves high-precision measurement of near in-situ core parameters and continuous 3D digital core fusion imaging, and is interconnected with the large-scale logging software CIFLog, providing strong support for timely discovery and efficient exploration and development of oil and gas.
Logging is the "eye" for understanding oil and gas, and the core tool for identifying and evaluating oil and gas reservoirs. However, with the shift of oil and gas exploration and development targets towards complex fields such as ultra deep, unconventional, and ultra-high water content, traditional logging techniques can no longer meet the high-precision measurement needs of reservoir porosity, fluid properties, and other factors.
In order to solve such bottleneck problems, the Exploration Institute took the lead in undertaking the key core technology research project "Development of Mobile Well Site Rock Sample Integrated Continuous Measurement Imaging System" of the group company in 2021, and formed a "cross unit, cross disciplinary, and cross professional" joint research team. San Ying Precision, with its leading position in the field of high-resolution X-ray 3D perspective imaging detection equipment with independent intellectual property rights in China, especially its outstanding strength in dual energy CT technology, has naturally become an indispensable key partner in the joint research and development team.
Over the past three years, the research team has unlocked three technical bottlenecks and overcome five core technologies through unremitting exploration and continuous tackling, successfully developing a vehicle mounted mobile "nuclear magnetic laser CT" integrated measurement equipment.
With outstanding research and development capabilities, rich experience in instrument manufacturing, and comprehensive testing accumulation, Sanying Precision has successfully deeply integrated X-ray 3D imaging technology into the field of digital rock core internal structure detection, achieving intuitive observation and accurate quantitative characterization of discontinuous structures inside rocks under the coupling of multiple physical fields such as stress field, seepage field, and temperature field. The micro characteristics of reservoir rocks are accurately digitized, providing a strong solution to major scientific and technological challenges faced by efficient exploration and development of unconventional oil and gas.
