摘要:

页岩油气资源潜力已经成为社会关注的重点,为了更好地了解页岩油气资源潜力,需要不断完善页岩油气资源评价方法,加强资源评价工作。页岩油气属于非常规油气资源,其地质特征与常规油气有明显的不同,因此常规油气资源评价方法不完全适用于页岩油气,需要发展适合页岩油气特点的资源评价方法。一般来说,页岩油气地质资源量较大,但是采收率较低,因此页岩油气资源评价不仅要关注地质资源量,更要重视可采资源量。页岩油气资源评价基本采用成藏思路而很少采用成烃思路。目前页岩油气资源评价主流的基本方法有两类:①基于页岩油气层含油气量的地质资源量评价方法;②基于单井页岩油气EUR的技术可采资源量评价方法。影响页岩油气资源评价的因素主要有地质认识、技术进步和经济因素,地质评价是资源评价的基础和关键。

Abstract:

The potential of shale oil/gas resources has become the focus of social attention. In order to better understand the shale oil/gas resources potential, it is necessary to constantly improve the methodology and strengthen the work of shale oil/gas resources assessment. Shale oil/gas belongs to unconventional resources, the geological characteristics of which are obviously different from those of conventional oil/gas, and the assessment methods for conventional oil and gas resources are thereby not fully applicable. Developing resources assessment method suitable for shale oil/gas is a must. Shale oil and gas resources are usually large-size in place, though with quite low recovery factor. Therefore, the specific resources assessment is supposed to stress both resources in-place and recoverable resources. At present, there are two main basic methods for shale oil/gas resources assessment, namely resource in-place assessment based on shale oil/gas content per unit volume and technically recoverable resource assessment based on shale oil/gas EUR per well. The factors that affect shale oil/gas resources assessment mainly include geological understanding, technology progress and economic factors, with geological evaluation as the foundation and key.

Key words: resources in-place, technically recoverable resources, economically recoverable resources, geological evaluation, resource categorization, assessment methodology, resource assessment, shale oil/gas
