中国石油战略选区重点目标油气地质条件分析及勘探建议

Analysis of petroleum geological conditions of key targets for strategic petroleum area selection in PetroChina and suggestions of exploration

首先,分析了中国石油天然气股份有限公司优选出的3个战略选区重点目标,即河套盆地、塔里木东南坳陷和羌塘盆地的油气资源条件,认为这3个目标都具有资源量大、资源丰度较高的特点,具有开展战略选区的油气资源基础。其次,论述了3个目标的储盖组合和油气显示情况,指出每个地区虽然具有不同的特点,但都具有基本的油气成藏条件和较好的勘探前景。最后,在分析3个目标存在的主要问题的基础上,提出了相应的勘探工作建议。

This paper analyzes three key strategic oil and gas target areas selected by PetroChina, i.e.： Hetao basin, Tadongnan （southeastern Tarim） depression and Qiangtang basin. They are characterized by abundant oil and gas resources and provided with the oil and gas resources basis for strategic area selection. Then the paper discusses the combination of reservoir and seal and oil and gas showings. All the three areas have essential oil and gas accumulation-forming conditions and better petroleum prospects though each area has its unique features. Finally some suggestions about the exploration are proposed on the basis of an analysis of the main problems concerning exploration of the three target areas.
