利用二氧化碳资源提高气田开发效益

酸性气田开发中应该考虑如何充分利用CO2以提高综合经济效益。CO2可应用于食品、焊接、消防、农业、油气开采、清洗、化工生产等许多行业。我国CO2消费市场潜力很大,高酸性气田巨量的CO2资源若是妥善利用,可产生良好的社会和经济效益。此外,“CO2排放权交易”所潜含的巨大的经济效益也不容忽视。在分析CO2利用项目的技术经济可行性的基础上,通过利用方案对比,建议采用MEA提浓 液化处理的工艺同时生产3×104t食品级和5×104t工业级液体CO2。     

Energy Storage Evolution Continues

Energy storage has been called a potential “silver bullet” for integrating large quantities of intermittent renewable (i.e., wind and solar) energy into the US electric grid. Let's take a look at how its evolution is going so far.     

Increased Investment Needed in Integrated Resource Planning

Integrated resource planning (IRP) by electric utilities in the United States is getting increasingly complex.     

China Committed to Environmental Protection with Increase of Clean Energy Consumption

Construction of the West-East gas transmission pipeline is a significant decision that the Chinese government made at the turn of the century, aiming at bringing the long-term benefits to the Chinese people. The project, starting from Tarim basin in West China‘s Xinjiang Autonomous Region and ending in Shanghai on China‘s eastern coastline, will stimulate the western economic development,accelerate adjustment of the eastern energy consumption structure and improve the environmental protection in the areas along the giant pipeline.……     

China Likely to Resume Oil Futures Soon

China is likely to resume operation of its oil futures this year, according to reports from the media about a futures conference organized by the Shanghai Futures Exchange (SHFE) in late May. "As China has become an important oil producer and consumer,the demand for our own oil futures market emerges,which will help China oil-related enterprises hedge risks," said Li Ruisheng, vice president of PetroChina's refining and marketing company.     

Oil Price Likely to Spur Chinese Industry Restructuring

Concern over surging oil prices could mean the restructuring and upgrading of China＇s industries, according to a United Nations Conference on Trade and Development （UNCTAD） official, who made those remarks in Changchun, the capital of Northeastern China＇s Jinlin Province, in early September, when the 4th Northeast Asia Investment and Trade Expo was held. ＂Commodity price hikes have severely affected the Chinese economy, but they also occurred as China faces industrial restructuring challenges,＂ said Li Yuefen, the UNCTAD Debt and Development Finance Branch head, adding that rising commodity prices and wages have made it increasingly difficult for China to sustain a competitive export edge.     

Grid-Interactive Water Heaters for Energy Storage

The US electric grid system is composed of four primary components: (1) large centralized power plants; (2) a backbone, high-voltage transmission network; (3) a “stepped down” subtransmission leg, and (4) distribution, the final leg that delivers electricity to end-users.     

China Likely to Stop Production of Liquefied Coal

China,which is rich in coal but poor in petrolcum and gas,may put an end to projects which are designed to produce petroleum by liquecfying coal,according to an official with the National Development and Reform Commission（NDRC）,the country＇s top cconomic planning agency.     

对林甸地区地热资源的初步认识

对影响地热资源分布因素、地热资源的储集和地热资源的分布进行了分析，针对松辽盆地北部林甸地区进行了地热资源的初步探讨，并绘制了林甸地区主要断层叠合图，构造叠合图，地热资源储集分布图，登娄库组和侏罗系沉积环境平面图，地热资源分布图。通过目前资料的分析，说明了地热资源对油田开发的积极意义。     

未来20年中国能源发展构想

中国经济现代化正面对能源的严峻挑战:能源供需矛盾尖锐;转换方式落后,能耗高,效率低;生态环境破坏严重,经济损失巨大。制定中国未来20年能源发展战略必须坚持科学发展观,综合考虑能源与经济、国家安全、社会生态环境和国民健康等诸多因素。我国未来20年应力争建设若干个新的油气能源基地;建立几个稳定的国外原油供应基地;制定促进能源发展的配套政策并建立监督、指导、咨询信息系统;合理调整各类能源在一次性能源消费中的比例;攻克新能源和洁煤关键技术,改革煤能转换方式;大力发展各种类型的水利发电;积极发展核电和新能源;提高水能、新能源、核能在一次性能源消费中的比例。     

复合储能控制系统在钻机制动能量回收中的应用

石油钻机在工作过程中由于制动能量无法回收利用,造成了能量的巨大浪费。采用储能单元可以在电机制动时回收能量,在电机负载增加时作为辅助动力源进行电能补充。然而,这类设备的储能单元易损坏、整体采购成本高,不利于在石油钻井行业推广应用。鉴于此,对钻机原有电控系统进行扩展,加入控制单元和储能单元,提出制动能量回收利用方案和复合储能单元的改良设计,并设计了该系统的控制策略、保护策略和储能单元的模糊控制。通过实际应用证明该系统可以改善电能的质量和降低生产成本,对制动能量的有效回收利用效果明显。最后指出该复合储能控制系统在石油钻井行业的应用前景十分广阔。
