Recognition of thin interbedded reservoirs in the middle-shallow strata in the Songliao Basin is a great difficulty. In order to resolve this problem, we present a technique for predicting the distribution of thin reservoirs using a broad frequency band and ultra high resolution seismic. Based on forward modeling, we recognized that a thin bed seismic reflection is characterized by changing amplitude with changing frequency （amplitude versus frequency, AVF）. We calculate the thickness of thin reservoirs from their AVF characteristics and predict the distribution of thin bed reservoir using broad frequency band and ultra high resolution seismic. The technique has been applied in the 3D seismic area of Zhaoyuan in the northern part of the Songliao Basin. The seismic resolution is increased by two or three times over that of conventional seismic and many thin reservoirs have been identified. The technique has extensive application to the exploration and development of oil and gas, such as optimizing the location of exploration wells, the design of wells （especially horizontal wells）, choice of production test layers, analyzing reservoir continuity in development wells, and so on.

随着我国双碳战略目标提出,电站锅炉向高参数方向发展。为研究新疆典型高氯煤在高参数锅炉焚烧过程中可能存在的腐蚀问题,探索防护措施,模拟了高参数下燃用高氯煤的锅炉气氛,对比了Super 304、T92、C-HRA-5、TP347H和12Cr1MoV的抗氯腐蚀能力并研究腐蚀温度(600、650和700℃)对氯腐蚀特性的影响。同时探究不同氧化钇质量分数(0%、0.2%、0.4%、0.6%和0.8%)的In⁃conel 625涂层的抗氯腐蚀能力。结果表明:腐蚀温度对材料的抗氯腐蚀能力影响很大,当温度高于700℃时,Super 304、T92、C-HRA-5、TP347H和12Cr1MoV均无法满足实际投产使用。在650℃时,C-HRA-5和TP347H表现良好,其拟合的腐蚀增重曲线分别为:y^(2)=312.371x,R^(2)=0.96和y=1.927x,R^(2)=0.94。Inconel 625涂层明显提高了12Cr1MoV基体抗氯腐蚀能力。随着涂层中氧化钇含量增加,抗氯腐蚀效果呈先升高后降低趋势,添加0.4%氧化钇效果最好。
