Physical and chemical environments of abnormal vitrinite reflectance evolution in the sedimentary basins

Based on the tested data of pressure and vitrinite reflectance of some wells in sedimentary basins, abnormal high pressure is regarded as not the only factor to retard the increase of vitrinite reflectance (R _o). Apart from the types of the organic matter, the physical environment (temperature and pressure) and chemical environment (fluid composition and inorganic elements) will result in the abnormal vitrinite reflectance values in the sedimentary basins. This paper tested trace elements and vitrinite reflectance data from the the abnormal high pressure and normal pressure strata profiles, respectively, and found that the acidic and lower salinity starta are favorable for the increase of R _o. By discussing the corresponding relationship between the contents of some trace elements in the mudstone and the vitrinite reflectance values, the typical trace elements were found to suppress and/or catalyze the vitrinite reflectance of organic matter, while the elements of Ca, Mn, Sr, B, Ba and P may result in the retardation of R _o. However, elements of Fe, Co, Zn, Ni and Rb may catalyze the organic matter maturation. This study is conductive to the organic maturation correction, oil and gas assessment and thermal history reconstruction by the paleothermometry.

It probes systematically into main requirements of the designing scale, farm site selection, arrangement of farm site area, engineering of the pond building, pumping station, water supply and drainage canals and electricity supply engineering of the culture pond.     

Sterol Distribution in Sediments from Chaiwobu Lake and Caohai Basin and Its Geochemical Significance

In order to understand the distribution characteristics of biomarkers in source rocks,which may be related to organic input,Quaternary sediments from the Caohai Basin and the Chaiwobu Lake were analyzed for sterols,As a result,various sterols,have been found in the sediments.The composition of sterols in the sediments revealed that cholesterols and cholestadienols are more abundant than their C29 counterparts in the Chaiwobu Lake sediments and that C29 sterols are more abundant in the peats from the Caohai Basin,It is also found that stanol/sterol ratios in clays are higher than in peats.Studies show that organic input to the Chaiwobu Lake is mainly plankton and zooplankton and to the Caohai Basin is mainly terrestrial high plant.The authors have proposed that the relative abundance of C27 or C29 sterane in source rocks may reflect input characteristics to some extent and the stanol/sterol ratios may reflect the redox conditions of the depositional environments.     

沉积盆地中镜质组反射率异常的物理化学环境探讨

根据实测的压力和镜质组反射率数据讨论了沉积盆地中镜质组反射率异常的物理化学环境.认为异常压力并不是导致镜质组反射率受到抑制的唯一原因;沉积盆地中有机质镜质组反射率异常的原因除与有机质本身的性质有关外,还与其所处的温度、压力等物理环境及其周围的流体性质、无机元素(矿物)的组成等化学因素密切相关.通过对钻井异常高压带和正常压力带剖面密集取样进行的微量元素与镜质组反射率分析表明,偏酸性、低盐度的流体介质有利于有机质镜质组反射率的增加;通过分析泥岩中的某些元素丰度与镜质组反射率的对应关系,初步确定钙、锰、锶、硼、钡、磷等元素对镜质组反射率的演化有抑制作用,而铁、钴、锌、镍、铷等元素对有机质的热演化具有催化作用.本研究对于有机质成熟校正、油气资源评价和利用成熟度古温标恢复盆地热历史都具有意义.     

江苏全省地面沉降InSAR监测

针对江苏省是长三角地区地面沉降比较严重的地区,InSAR技术作为最有效的地表形变监测手段,曾被用来获取江苏局地的地面沉降信息,但用于全省域监测尚无先例的现状。该文介绍了利用时间序列InSAR技术开展江苏全省地面沉降监测的方法和成果,提出了适用于区域级和国家级合成孔径雷达干涉测量(InSAR)形变监测的技术方法,给出了基于ALOS PALSAR影像和RADARSAT-2影像的江苏全省2007-2011年及2012-2015年2个时段的地面沉降监测成果,利用江苏省CORS站数据,对InSAR获取的地面沉降速率进行了精度评价。结果表明,2个时段的InSAR监测结果的精度分别为3.8(mm·a^-1)和4.0(mm·a^-1)。最后对2个时段的全省地面沉降的时空分布、动态变化情况进行了分析,并对InSAR监测成果的应用前景进行了展望。
