测井技术在灰岩地区隧道深孔勘探中的应用

鄂西地区完整灰岩地层的视电阻率、密度、声波、自然伽马等曲线形态受灰岩胶结物质成份和泥质含量影响并具有一定的规律性，当灰岩地层受到构造、溶蚀作用产生破碎带、岩溶、裂隙等不良地质体或存在地下含水体时，各测井物理参数发生变化并在曲线形态上呈现异常反映，据此可以对不良地质体的位置、规模、类型进行准确判断。测井技术在鄂西地区灰岩地区隧道深孔勘探中的应用，补充、验证了钻探资料，为隧道设计、施工提供了可靠的依据。     

成像测井技术在碳酸盐岩水平井中的应用

塔里木盆地北部地区碳酸盐岩油藏储层，非均质性较强，只依靠常规测井判断碳酸盐岩裂缝、溶孔、溶洞很困难．利用地层微电阻率扫描成像(FMI)，对碳酸盐岩水平井储层进行定性分析、定量解释，并能准确识别出碳酸盐岩目的层裂缝的性质、大小、开度、溶蚀孔洞原生孔隙、次生孔隙的发育情况等．同时并利用测试、酸压资料验证了使用成像测井判断裂缝的有效性．     

液压传感间接测量水位计的研制及其应用

压力式水位计在水文自动测报系统中很难推广的主要原因是泥沙对传感器的影响,泥沙不但会使传感器测量精度达不到测验要求,而且由于泥沙淤积还会给水位计的日常维护带来很大不便。目前进口传感器测量精度高、稳定性能好,但仍避免不了泥沙的影响。针对这一问题,提出了一种新型压力式水位计———液压传感间接测量水位计,该水位计解决了泥沙对压力式水位计的影响,是一种具有很大发展前景的水位测量仪器。

Estimating coefficients of volume compressibility from compression of strata and piezometric changes in a multiaquifer system in west Taiwan

This paper estimates the coefficients of volume compressibility from variation in compressible layer thickness and changes in piezometric heads by using detail ground surface surveys and a multilayer monitoring well at a selected site (Shigang) within the Choshui River alluvial fan in west Taiwan. The paper integrates various types of in situ monitoring tools, including leveling surveys, continuous global position system (GPS) stations, multilevel layer compression and groundwater pressure head-monitoring wells, to investigate the situation and progress of the subsidence problem in the region. The results from the cross-analyses of the measured data show that surface settlement caused by the compression of strata is between the depths of 60 and 210 m where the clayey stratum within 120-180 m was most pronounced and contributes up to 53% of the total compression. The results indicate that the clayey stratum is under normal consolidation. The results also reflect the fact that 20% of settlement contribution comes from the sandy stratum within 90-120 m; the elasto-plastic behavior of this sandy stratum is clear. The coefficients of volume compressibility of the clayey and sandy stratum analysed from the stratum's compression records; they were 6.38×10⁻⁸ and 5.71×10⁻⁹ m²/N, respectively. Ultimately, this parameter estimation would permit to control and predict land subsidence based on change in pressure head which are related to groundwater extraction.     

Maximum Storm Surge Curve Due to Global Warming for the European North Sea Region During the 20th–21st Century

Computations of storm surges during the 20th century needs to incorporate globalwarming of about 0.6 °C ± 0.2 °C (IPCC, 2001). In order totake this global warming into consideration, the development of all storm surgesoccurred during the 20th century have been analysed. The study comprises determiningto what degree the storm surge curve and storm surge level depend on each other. Thisfact can be used to calculate a maximum storm surge curve and each single storm surgeevent can be summarised. The tendency of the surge and wind parameters do not showthat this maximum storm surge levels in the 20th century will occur earlier than predicted, however, the global warming of 0.6 °C will extend the duration of the mean storm surge curve.
