Quick On-site Testing, Precise and Efficient! Rapid Assessment of Coalbed Methane Reservoir by Shenkai SKNM12
In the exploration and development of coalbed methane, nuclear magnetic resonance technology is mainly used for laboratory testing and interpretation of reservoir core characteristics, including lithology, physical properties, oil, gas and water properties, etc., and providing key parameters for reservoir assessment. However, it requires a long period of time to take the core back from the site and analyze it in the laboratory, and some parameters (such as oil and gas loss rate) are variable during this process, which results in differences from the original state and affects the accuracy of subsequent reservoirs and production parameters assessment. In addition, the laboratory equipment is large and expensive, and the means of timely reservoir assessment or providing assessment related parameters for on-site logging are relatively limited. So there is an urgent need for a portable device and application technology suitable for on-site and real-time analysis of rock cores (cuttings).
