Energy plays an intuitive and important role in today's human development and global pattern. The geopolitical crisis caused by this is becoming increasingly fierce and the world energy price wave. In order to seek a more stable source of energy to get rid of the limitations of fossil energy, new energy becomes a new direction of development. In theory, only 23% of the Earth's potential renewable energy (solar, tidal and wind) could be converted to meet today's energy needs, but due to time and geographical factors, utilization is still low. Therefore, the development of heat energy storage technology is of great significance to alleviate energy pressure and promote sustainable development of social economy. In recent years, heat energy storage technology has become one of the most attractive heat energy utilization technologies and has attracted wide attention. At present, it has become a research hotspot worldwide. This paper summarizes the latest research status of heat storage technology in recent years, including the new progress of some technologies. Different heat storage technologies are suitable for different environment and use background, and different energy storage technologies are compared, so as to facilitate the analysis and research of new energy heat storage research under different circumstances.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86248855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is urgent to implement the sedimentary microfacies and sand body distribution characteristics of the Fuyu oil layer in the Xinbei area, providing a new theoretical basis for predicting the \"sweet spot\" of facies control in the area. Using core, logging, and logging data from the study area, a high-resolution sequence stratigraphic framework of the Fuyu oil layer was established. The distribution characteristics of sedimentary microfacies within the sequence framework were analyzed. The study showed that the Fuyu oil layer in the study area was divided into one long-term base level cycle of rising half cycle, four medium-term base level cycles, and 13 short-term base level cycles; In the area, river controlled shallow water delta plains and front sediments are developed, and a total of 10 types of sedimentary microfacies have been identified. Among them, the (underwater) distributary channel sand body, as the dominant reservoir sand body, extends along the southwest to northeast direction. As the A/S value increases, four stacking styles are developed vertically, including vertical shear stacking, staggered shear stacking, horizontal shear stacking, and isolated distribution. In the horizontal, the locally developed wide channel sand body composite zone gradually transitions into a single channel.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75584120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bangham kinetic model was used to fit the adsorption process, and constants representing the adsorption rate were obtained. The following understandings were obtained: (1) With the decrease of particle size, the adsorption equilibrium time is shorter, small particle size samples often have more complex pore structure, which makes the adsorption reaction between gas-solid interface more active, but the particle size itself cannot increase or reduce the size of the accumulated adsorption amount at the equilibrium, it only changes the length of time required to reach the adsorption equilibrium. (2) With the increase of the mesh number, the adsorption rate also increases, but the higher the coal rank, the greater the adsorption rate growth rate.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"72 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87734881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, the research of geothermal resources in North Songliao Basin has mainly concentrated in the shallow layers where low-temperature geothermal resource is mainly developed. However, the research of deep geothermal resource in high-temperature hot dry rock is still in a blank state. Based on the Songliao Basin exploration and research achievements as well as oil exploration well data, this paper further improves geothermal resource exploration and development theories of North Songliao Basin by researching geothermal resources in high-temperature hot dry rock. Hot dry rock distribution is relatively concentrated in the North Songliao Basin, mainly in the central, southern and southeastern part of the study area, where the depth of 150 ℃ isothermal surfaces substantially less than 5km is conducive to the development of hot dry rocks. Studies have shown that two high value areas of terrestrial heat flow in the North Songliao Basin are respectively located in the southern part of the central depression area as well as the junction of three first-order tectonic belts including central depression, southeast and northeast uplift areas, where geothermal resource potential of hot dry rock is great. By using enhanced geothermal system, mining hot dry rock is feasible. This study has some guidance and reference for the development and utilization of deep geothermal resources in hot dry rock of the North Songliao Basin.","PeriodicalId":14093,"journal":{"name":"International journal of energy science","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74782098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
