1、 2022年年职称英语英汉对照上百例精选(第四十篇)40、石油地质学与其它科学、 1. Petroleum geology is the application of geology (the study of rocks) to the exploration for and production of oil and gas. Geology itself is firmly based on chemistry, physics, and biology, involving the application of essentially abstract concepts to obse
2、rved data. In the past these data were basically observation and subjective, but they are now increasingly physical and chemical, and therefore more objective. Geology, in general, and petroleum geology, in particular, still rely on value judgements based on experience and an assessment of validity
3、among the data presented. 1、石油地质学是地质学(岩石讨论)在油气勘探开发和生产中的应用。地质学本身是以化学、物理和生物学为根底，应用其根本的抽象理论概念来解释观看到的资料。在过去，这些资料主要凭主观观看猎取。现在借助物理和化学手段，因而更具客观性。从根本上讲，地质学和石油地质学，仍旧特殊依靠于基于阅历的数值推断和对现有资料的有效性评估。 2. The application of chemistry to the study of rocks (geochemistry) has many uses in petroleum geology. Detailed kn
4、owledge of the mineralogical composition of rocks is important at many levels. In the early stages of exploration certain general conclusions as to the distribution and quality of potential reservoir could be made from their gross lithology. For example, the porosity of sandstones tends to be facies
5、 related, whereas in carbonate rocks this is generally not so. Detailed knowledge of the mineralogy of reservoirs enables estimates to be made of the rate at which they may lose porosity during burial, and this detailed mineralogical information is essential for the accurate interpretation of geophy
6、sical well logs through reservoirs. Knowledge of the chemistry of pore fluids and their effect on the stability of minerals can be used to predict where porosity may be destroyed by cementation, preserved in its original form, or enhanced by solution of minerals by formation waters. 2、化学应用到石油地质的岩石讨论
7、(地球化学)中有很多作用。岩石矿物组分的具体资料在很多方面很重要。在勘探早期，就潜在储层的分布和质量我们可以从总的岩性得出某些通用的结论。例如，砂岩孔隙度一般与相有关，而一般在碳酸盐岩中则并非如此。储层矿物学的具体学问可以帮忙我们估量出在埋藏过程中孔隙度损失的速率。这样具体的矿物组分资料对于精确地解释储层地球物理测井特别必要。了解孔隙流体的化学组成及其对岩石稳定性的影响，有助于猜测哪些地区孔隙度因胶结作用而变差，哪些地区孔隙度保持不变，哪些地区孔隙度因地层水的溶蚀作用而提高。 3. Organic chemistry is involved both in the analysis of oi
8、l and gas and in the study of the diagenesis of the plant and animal tissues in sediments and the way in which the resultant organic compound, kerogen, generates petroleum. 3、有机化学则可应用于分析原油和自然气，讨论沉积物中植物和动物组织的成岩作用，讨论动植物组织转化为合成有机化合物，提醒由此而生成的有机化合物干酪根生成石油的方式。 4. The application of physics to the study of
9、 rocks (geophysics) is very important in petroleum geology. In its broadest application geophysics makes a major contribution to understanding the earth”s crust and, especially through the application of modern plate tectonic theory, the genesis and petroleum potential of sedimentary basins. More specially, physical concepts are required to understand folds, faults, and diapirs, and hence their roles in petroleum entrapment. 4、在石油地质中，将物理应用到岩石讨论(地球物理)中很重要。地球物理的广泛应用对于了解地壳，尤其是应用了现代板块构造理论后，对于了解沉积盆地的成因和潜在石油资源作出了重要奉献。更为特殊的是，在理解褶皱、断层和底辟以及它们在石油圈闭过程中的作用时需要物理概念。
