RESEARCH OF THE INHOMOGENEITY TEST OF CLIMATOLOGICAL DATA SERIES IN CHINA*

Some achievements on the inhomogeneity test of climatological data series and some correlative conclusions were described,from which we concluded that it was very necessary to test the homogeneity of the Chinese climatological data series.Many techniques on this field developed by foreign experts are suitable for Chinese climatological series,and the main factors for the inhomogeneity of the Chinese climatological data are the relocation of stations and the change of instruments.     

THE ANALYSIS ON THE STATISTICAL CHARACTER OF QUIKSCAT SCATTEROMETER WINDS AND STRONG WIND FREQUENCY USING REMOTE SENSOR DATA FROM QUIKSCAT

1 INTRODUCTION Most of the conventional sea surface wind data are measurements from ships, buoys and islands, with coverage and spatial resolution far below the requirements of research and application. At present, due to limited understanding of physical processes and efficient exploitation of data, numerical prediction models have not been used as they should be, although routine procedures are able to give sea surface wind fields at the intervals of 6 hours. With the development of sp…

新疆洛浦县和巴楚县晚石炭世—早二叠世牙形石动物群及其地层意义

本文依据对新疆洛浦县阿其克和巴楚县小海子剖面牙形石动物群研究，详细探讨了塔里木盆地西部石炭－二叠系界线的划分和克孜里奇曼组、南闸组和康克林组上部地层的归属问题；指出从牙形石的发展和演化看，上述地层应属于下二叠统。     

临兴上古生界致密储层裂缝发育特征及对致密气富集影响

临兴区块上古生界储集层为致密砂岩，裂缝发育特征及对致密气富集影响尚不清楚，一定程度上制约了甜点区预测。 根据岩心、露头、薄片及测井资料，分析了研究区裂缝发育特征，探讨了裂缝对致密砂岩气富集的影响。临兴区块上古生界主 要发育高角度缝，其次为中低角度缝及水平缝，微观上根据裂缝与矿物颗粒的相对位置关系，可识别出粒内缝、粒缘缝和穿粒 缝，其中粒缘缝最为发育。受塑性泥岩阻挡，裂缝垂向延伸较差，一般延伸1~2 m后消失于泥岩层中，受燕山期北西—南东向 地应力影响，裂缝走向多为北东—南西向，裂缝密度一般2~5条/ｍ。裂缝可改善储集空间、提高油气充注效率，储层裂缝发育 区渗透率可增大1~2个数量级，含气饱和度高，此外，研究区裂缝是油气垂向运移的有效通道，影响着石盒子组及石千峰组致 密气的富集，在后期的勘探开发过程中应充分寻找裂缝发育区，并通过进一步压裂获得高产。
