A hybrid physics-informed data-driven neural network for CO_(2) storage in depleted shale reservoirs

To reduce CO_(2) emissions in response to global climate change,shale reservoirs could be ideal candidates for long-term carbon geo-sequestration involving multi-scale transport processes.However,most current CO_(2) sequestration models do not adequately consider multiple transport mechanisms.Moreover,the evaluation of CO_(2) storage processes usually involves laborious and time-consuming numerical simulations unsuitable for practical prediction and decision-making.In this paper,an integrated model involving gas diffusion,adsorption,dissolution,slip flow,and Darcy flow is proposed to accurately characterize CO_(2) storage in depleted shale reservoirs,supporting the establishment of a training database.On this basis,a hybrid physics-informed data-driven neural network(HPDNN)is developed as a deep learning surrogate for prediction and inversion.By incorporating multiple sources of scientific knowledge,the HPDNN can be configured with limited simulation resources,significantly accelerating the forward and inversion processes.Furthermore,the HPDNN can more intelligently predict injection performance,precisely perform reservoir parameter inversion,and reasonably evaluate the CO_(2) storage capacity under complicated scenarios.The validation and test results demonstrate that the HPDNN can ensure high accuracy and strong robustness across an extensive applicability range when dealing with field data with multiple noise sources.This study has tremendous potential to replace traditional modeling tools for predicting and making decisions about CO_(2) storage projects in depleted shale reservoirs.

Reform Exploration for Safety Course System of Oil and Gas Storage and Transportation Facilities

In recent years,the safety of oil and gas storage and transportation facilities has been paid more attention by the state and enterprises due to frequent accidents.The oil and gas storage and transportation facilities safety courses in China University of Petroleum(Beijing)includes“Engineering mechanics”,“Strength design of pipelines and tanks”and“Safety and integrity management of oil and gas storage and transportation facilities”.The three courses lack relevance and the teaching mode is too rigid,resulting in students losing their initiative in learning.If students can’t use the knowledge flexibly,it will affect the achievement of the objectives of the training program.Therefore,oil and gas storage and transportation facilities safety courses are reformed,training plans are adjusted and teaching methods are improved.The practice shows that the reform enriches the teaching content,improves the teaching quality,stimulates classroom activity and gets a good evaluation of students.The reform of safety courses has a certain significance for cultivating compound talents who have the ability to solve practical problems in engineering.

中国氦气全产业链发展现状与展望

中国氦气供应短缺、产业发展基础薄弱,过去长期处于“有业无链”状态。近年来,国内自给率虽大幅提高、并于2023年首次实现对外依存度低于90%,但因自产气量基数较小,尚未形成完善可靠的氦气“产供储销贸研”全产业链。结合全球氦气产业链发情况,基于中国氦气产业链资源、生产、供应、储存、运输、销售、技术和装备等全链现状,分析认为:2025年起,全球氦气供需双涨,远期或将呈供应宽松态势;未来5年内,随着国内自产气量稳定增长和进口渠道的开拓,预计中国氦气将呈自产和进口“两旺”局面,保供能力将大幅提升,同时国内超低温领域科技攻关厚积薄发,正在攻关的关键技术及装备逐步进入应用推广阶段,中国氦气产业链发展必将迎来长足进步,预计很快形成完善可靠的产业链。建议中国加大氦气资源勘查力度,深入夯实资源基础,持续加强科技创新,尽快形成关键装备的系列化、工业化产品,同时依托气田开发和液化天然气国际合作机制,积极构建稳定供应的多元化进口保障体系,从而实现中国氦气的安全可靠供应和产业健康发展。
