摘要:

页岩油是以游离(含凝析态)、吸附及溶解(可溶解于天然气、干酪根和残余水等)态等多种方式赋存于有效生烃泥页岩地层层系中且具有勘探开发意义的非气态烃类。根据泥页岩地层中所含烃类相态、成因机理及勘探开发等特点,将页岩类油气划分为页岩气和页岩油等两类八种。结合页岩油特点,指出了我国页岩油形成条件和分布规律,即规模分布的有效生烃泥页岩、形成于深水半深水相的富有机质泥页岩、较高的有机质丰度和适当的热演化程度以及较好的基质物性条件等是页岩油形成的主要条件。建立了中国陆相断陷湖盆页岩油发育模式,指出概率体积法可以作为页岩油资源评价的主要方法,提出了页岩油远景区、有利区及目标区优选的参数体系和标准。作为非常规油气能源的主要类型之一,页岩油将会对我国能源结构产生重要影响。

Abstract:

Shale oil is liquid hydrocarbon formed in the effective source rocks with free phase(condense oil), adsorbed and dissolved phase(dissolved in gas, kerogen and residual water). According to hydrocarbon phase, genesis and exploration procedures of hydrocarbon within the shale, the shale oil and gas are classified into two groups and eight classes. Based on the shale oil characteristics in China, the shale oil forming conditions and distribution law were concluded. Large scale distribution of effective shales, development of organic rich shales in deep waterhalf deep water with thermal maturity, and good matrix physical properties are the necessary conditions for the formation of shale oil. Furthermore, we created the shale oil development mode in the continental faulted lake basin, and pointed out that the probability volumetric calculation method can be used to assess shale oil resource, and also put forward the parameter system and criteria for shale oil prospective area, favorable area and target area. The success in shale oil development has significant impact on the energy consumption structure in China.
