为了给中国煤系气勘探开发提供借鉴和参考,基于非常规油气地质学理论及最新研究成果,构建了煤系气甜点区(段)评价方法。研究结果表明:①构建了包含4个要素共计15项指标的煤系气地质-工程甜点评价体系,其中的第一个要素是煤系富气甜点地质参数,应重点评价煤系储层性质及地质力学层变形演化、规模及保存条件;②第二个要素是互层性煤系气渗流能力,要深刻揭示煤系气成藏模式、游离气与吸附气动态转换、天然裂缝发育特征、互层结构跨层渗流及复合断裂系统渗流异质性等;③第三个要素是含气量预测,应构建适合高频旋回互层结构煤系且与产能释放能力相匹配的含气量评价模型,准确评估煤系气资源量;④第四个要素是煤系合压储层改造,要重点评价岩石力学属性、地应力及脆性,结合动态监测技术优化合压效果,形成四维压裂技术方案;⑤煤系气甜点优选应综合考虑烃源性、储集性、含气性、保存性、成缝性、储改性和经济性。中国煤系气未来的发展趋势及建议:①深层煤层气(煤岩气)及铝土岩气将成为煤系气勘探开发的新对象、新方向;②深部煤系非常规天然气聚集成藏理论逐步形成;③强化多尺度孔缝表征、跨层渗流、合压增透、数智化新型天然气工厂排采模式等方面的研究;④联合多学科持续开展各类煤系气资源甜点综合评价,以助力煤系气勘探开发向深部进军。

长江干流广布的季节性淹水造成的江心洲岛湿地,具有保护生物多样性、净化环境等重要生态作用,是长江流域生态安全保障的重要物质基础。长江流域湿地的分布、动态及其生态意义受到广泛关注,而其重要组成部分之一的长江干流江心洲岛湿地研究报道相对较少。利用Google earth高清遥感影像目视解译提取江心洲岛湿地,采取GIS方法提取河道形态指标,采用相关分析及有序逻辑回归分析,揭示了长江干流江心洲岛湿地分布格局,探讨了河道形态要素对其影响。结果表明:长江干流江心洲岛湿地空间上呈现四段式分布,即宜宾-忠县河段,仅有中小型江心洲岛湿地分布;忠县-宜昌河段,完全没有江心洲岛湿地分布;宜昌-九江河段,以中小型江心洲岛湿地为主;九江-长江口河段,各面积水平江心洲岛湿地广泛发育,中小型江心洲岛湿地比上游更密集而大型江心洲岛湿地无明显差异。长江干流小型江心洲岛湿地数量多,大型江心洲岛湿地数量少。大型江心洲岛湿地比小型的对河道形态更为敏感。江心洲岛湿地面积与河宽、河宽差有显著正关系,与两岸差有显著负关系;宽阔的、顺直对称的河道平面形态更有利于大型江心洲岛湿地的演化。

The geothermal resources in the southwest section of the Mid-Spine Belt of Beautiful china are abundant,but the quantitative prediction and evaluation of geothermal resources are very difficult. Based on geographic information system (GIS) and remote sensing (RS) platforms,six impact factors,namely land surface temperature,fault density,Gutenberg–Liszt B value,formation combination entropy,distance to river and aeromagnetic anomaly were selected. Through the establishment of the certainty factor model (CF),weights of the information entropy certainty factor model (ICF) and weights of the evidence certainty factor model (ECF),the geothermal potential in the study area were predicted quantitatively. Based on the ECF results,the six main geothermal resource areas were de{3.eated. The results show that (1) ECF had high prediction accuracy (success index is 0.00405%,area ratio is 0.867);(2. The geothermal resource areas obtained were Ganzi–Ya’an–Liangshan,Panzhihua–Liangshan,Dali–Chuxiong,Nujiang–Baoshan,Diqing–Dali,and Lijiang–Diqing. The results provide a basis for the effective development and utilization of geothermal resources in the southwest section of the mid-ridge belt.

固体氧化物电解池(SOEC)中阳极析氧反应动力学较为迟缓,限制了SOEC器件电催化转化能力,因此针对阳极材料的改性研究对于进一步提升SOEC电化学性能十分关键。高熵钙钛矿(HEP)在许多反应中表现出良好的催化活性,但在SOEC中的应用鲜有研究。本文通过在双钙钛矿的A位或A'位分别掺杂不同的稀土金属、碱土金属或碱金属离子,合成了(Pr_(0.2.La_(0.2.Sm_(0.2.Nd_(0.2.Gd_(0.2.)BaCo_(2.O_(6-δ)(A-HEP)和Pr(Ba_(0.2.Sr_(0.2.Ca_(0.2.Na_(0.2.K_(0.2.)Co_(2.O_(6-δ)(A'-HEP)两种高熵钙钛矿材料。由于掺杂离子平均半径和氧化态的差异,A-HEP保持四方双钙钛矿相结构而A'-HEP则转变为正交单钙钛矿相。物理化学表征结果表明,A-HEP中Co平均价态更高,Co 2.-O 1s杂化更强,从而增加了电子转移路径并降低了转移能垒。同时,A-HEP中表面氧空位浓度更高,可为阳极析氧反应提供更多的活性位点。因此,在具有A-HEP阳极的SOEC中,与氧输运、电子传输和表界面反应过程相关的阳极极化电阻显著降低,并在800℃下实现最高1.76 A·cm^(-2.的电流密度和2.0 h的稳定性。本工作为高熵钙钛矿材料在SOEC阳极中的应用提供了新的策略。
