含油气盆地水文地球化学研究方法

The hydro-geochemical research methods of petroliferous basin

以水文地球化学观点研究油气成藏规律,指出油气富集的有利地区。首先要查明在地质历史发展过程中含油气盆地与自流水盆地的关系,遵循从区域到局部的研究原则;其次要确切地划分含水岩系,这是研究地下水运动和水化学成分组成的基础,并可将水动力学和水化学作为统一场进行综合研究。另外,取得可靠的水样和分析资料,选取有效的水化学参数,是研究水化学成分及其与油气关系的必要条件。

From the hydro-geochemical studies on the rules of oil and gas accumulation, this paper has concluded that to dehneate favorable region of rich oil and gas, first of all, we have to identify the relationship between the petroliferous basin and artesian basin in the geologic history of the development process following the research principle from regional to local. Secondly dividing of waterbearing rock series provides a basis to study the groundwater movement and the chemical composition of water, and then we can integrate water power and water chemistry as a comprehensive study of unified field. In addition, we have to obtain reliable information and analysis of water samples. Effective water-chemical parameters selection is also a necessary condition to study the chemical composition of water and the relationship of composition with the oil and gas.
