Specifications for capacity calibration of underground water-sealed rock cave oil depots released

　　A few days ago, the Zhejiang Provincial Local Metrology Technical Specification "Capacity Calibration Specification for Groundwater Sealed Stone Cave Oil Storage", which was drafted by the Zhoushan Quality and Technical Supervision and Inspection Institute of Zhejiang Province, was released, filling the domestic groundwater sealed stone cave oil storage capacity value.
The blank of the traceability system
.

　　Groundwater sealed rock cave oil storage refers to the underground space system excavated in the rock mass of a certain depth below the stable groundwater level, which uses the principle of water sealing to store oil and gas energy.
The main storage methods of energy such as petroleum and liquefied gas in the world, the accuracy of its capacity measurement is related to the strategic security of national petroleum reserves
.

　　Zhoushan Institute of Quality and Technical Supervision and Inspection fully investigated the underground water-sealed cave oil depots in Huangdao and Zhanjiang in the early stage, collected relevant standards and technical data, consulted relevant experts, and aimed at a wide range of domestic and foreign measurement technology institutions, production and use units, university research institutes, etc.

The specification was approved by an expert group organized by the Zhejiang Provincial Market Supervision Bureau at the end of 2021, and was later revised and improved, submitted for approval, and publicized
.

　　The release of the calibration specification provides an effective calibration method and technical basis for solving the problem of capacity measurement of underground water-sealed cavern oil depots, and will provide strong technical support for the construction of energy storage depots such as groundwater-sealed cavern oil depots in coastal areas of China
