长城钻探自主研发变黏压裂液体系获国家发明专利2021年7月初,使用长城钻探研发的变黏滑溜水压裂液体系的威204H23平台,测试产量达到117.9万立方米,是长城钻探2021年首个实现百万立方米的深层页岩气平台。6月底,长城钻探压裂公司申报的发明专利“压裂液原液、酸化压裂液、降阻水和挟砂压裂液及其制法”顺利通过国家知识产权局审查并获得授权。该专利的核心即变黏滑溜水压裂液体系。该体系针对深层页岩气埋藏深、压裂施工压力高、加砂难度大等问题,依托长城钻探公司科技项目,经过上百组室内研发及性能评价试验,攻克了液体变
In this work,highly dispersed atomically-thin MoS2 nanosheets were fabricated at one thousandth of the commercial cost using sepiolite(SEP)mineral nanofibers as carriers via a microwave hydrothermal method.Atomresolved microscopy revealed the MoS2 nanoshe
The use of nanofillers with high surface area and extreme purity in polymer composite is an effective strategy to obtain high performance polymeric nanocomposites.Therefore,the effect of nanofillers such as carbon nanotubes(CNT),titanium dioxide(TiO2
Electrospinning is a popular method for generating long and continuous nanofibers due to its simplicity and versatility.However,conventional electrospun products have weak strength and low availability,which restrict their functionality in complex applica
Supercapacitors(SCs)have attracted extensive attention due to their ultrahigh power density,fast charging/discharging rate,excellent electrochemical stability and environmental friendliness.Currently,the main commercial electrode materials for SCs are car
市场方面,近期全球能源危机日益严重,引发投资者对能源价格上涨甚至经济滞胀的担忧。安信证券认为,当前全球多地呈现不同程度能源危机,根本原因在于新旧能源转换期旧能源退出与新能源发展之间的脱节。从短期来看,随着俄欧博弈暂告一段落,俄罗斯对欧洲供气量有望提升,欧洲能源危机有望获得缓解;对于中国经济和A股来说,投资者的担忧主要来自于两点:一是能源价格上涨是否会引发整个物价上涨,形成“滞胀”环境导致股债双杀;
Oxygen reduction reaction(ORR)constitutes the core process of many energy storage and conversion devices including metal–air batteries and fuel cells.However,the kinetics of ORR is very sluggish and thus highperformance ORR electrocatalysts are highly reg
传闻1“智慧易通基础服务平台V5.1”评获“2021年度优秀软件产品”。  求证:属实。  近日,有投资者咨询正元智慧(300645):“公司开发的‘智慧易通基础服务平台V5.1’荣获‘2021年度优秀软件产品’,这个消息属实吗?公司和蚂蚁金服阿里云等公司合作项目会不会持续运行,并加深合作?公司有进行的新产品新项目的研发吗?”  对此,正元智慧表示消息属实。正元智慧称:“2021年9月24日,中国
The high sensitivity of room-temperature gas sensors is the key to innovation in the areas of environment,energy conservation and safety.However,metal-oxide-based sensors generally operate at high temperatures.Herein,we designed three ZrO2-base
