我国常规与非常规石油资源潜力及未来重点勘探领域
|
摘要
油气资源是油气工业的基础,极大地关系到国民经济的发展。近年来,我国的石油勘探形势发生了明显的变化:年新增石油探明储量下降,石油年产量连续3年(2016—2018年)下降,2018年石油对外依存度高达73%。因此,亟需对油气资源状况开展全面客观的评价,夯实国内常规与非常规油气资源的基础,明确剩余油气资源的重点勘探领域与有利勘探方向。中石油以近十几年来取得的油气勘探成果、地质认识成果与资料积累成果为基础,攻关形成常规与非常规油气资源评价方法技术体系,针对中石油矿权区及全国主要含油气盆地系统开展了第四次油气资源评价。评价结果显示:我国常规石油地质资源量约为1080×10~8 t;非常规石油地质资源量为672.08×10~8 t,其中包括致密油125.80×10~8 t,油页岩油533.73×10~8t,油砂油12.55×10~8 t。陆上常规剩余石油资源主要分布在岩性-地层(碎屑岩)、复杂构造2大重点领域;海域石油资源主要集中在海域构造、生物礁和深水岩性3个领域。在剩余石油资源分析的基础上,优选出常规石油现实有利目标区带20个,致密油有利目标区带12个,油页岩油露天挖掘目标6个、原位改质目标4个,油砂油有利目标5个。
Oil and gas resources are the basis of oil and gas industry, which greatly affects the development of national economy. China's oil exploration situation has undergone significant changes: the annual increase in proven oil reserves has declined, the annual oil production has declined for three years(2016-2018), and the external dependence of oil in2018 is as high as 73%. Therefore, it is urgent to carry out a comprehensive and objective evaluation of the status of oil and gas resources, consolidate the basis of domestic conventional and unconventional oil and gas resources, and clarify the key exploration areas and favorable exploration directions of remaining oil and gas resources. Based on the achievements of oil and gas exploration, geological recognition and data accumulation in recent 10 years, PetroChina has setup a technical system of conventional and unconventional oil and gas resource evaluation. The 4 th oil and gas resources evaluation has been carried out for PetroChina's mining areas and major petroleum basins in China. The evaluation results show that the amount of China's conventional oil geological resource is about 1 080×10~8 t, and that of unconventional oil is 672.08×10~8 t, including 125.80×10~8 t of dense oil, 533.73×10~8 t of oil-shale oil, and 12.55×10~8 t of oil-sand oil. The remaining conventional oil resource on land are mainly distributed in fields of lithology-stratigraphy(clastic rocks) and complex structures, while those in sea areas are mainly concentrated in three fields: marine structure,reef and deep-water lithology. Based on the analysis of remaining oil resource, 20 realistic favorable zones for conventional oil, 12 favorable target zones for tight oil, 6 open-pit targets for oil-shale oil, 4 in-situ reconstruction targets for oil-shale oil, and 5 favorable targets for oil-sand oil were selected.
