| 中文摘要:<正> 一、指导思想和找油步骤 (一)地质力学找油的指导思想 找油工作历来有两种不同的找油思想:1.强调地层,首先着眼于含油地层和生油地层,把地层视为找油的主要矛盾;2.强调地质构造,首先着重地质构造的分析,从寻找储油构造着眼,把地质构造视为找油的主要矛盾。 根据第一种看法,把第三系、白垩系、侏罗系、三叠系、二叠系乃至奥陶系、寒武系,甚至更古老的地层作为找油的目的层。根据第二种看法,先分析地层沉积地区的分布规律,是受什么构造条件控制和影响,并在上述广大的沉积地区内,寻找储油构造。地质力学找油就是属于第二种看法的。 |

| PROSPECT OF OIL RESOURCES IN CHINA AS VIEWED FROM GEOMECHANICS |

| Abstract:The location of oil provinces from an analysis of the tectonic systems existing in a givenarea constitutes the starting point in the search for oil by using the principles of geomechanicsas a guide. It is followed by the delineation of oil fields within an oil province which is refer-red to as a depressed part of a first-order tectonic system in which a thick sedimentary pilemost favourable for the formation and accumulation of oil builds up. An oil field occurs in pla-ces where good reservoir conditions are provided. The distribution of oil provinces is controlled by first-order terctonic systems, while oil fields are often localized in tectonic element of the 2rd, 3rd or still lower order. Exploration practice shows that shear structures or rotational shear structures are the most preferential sites for oil accumulation and may serve as an important indication of a buried oil field. |
