Abstract

Abstract:

The consumption and production of conventional energy set a new record high in 2012, oil and gas are still the mainstays in energy consumption structure, while the drastic increase in unconventional oil and gas production make a near balance between demand and supply of oil and gas. However, a lot of basic theoretical questions about unconventional oil and gas are still waiting to be answered, and little is known about the accumulation pattern and exploration -development features of unconventional oil and gas. The paper reviews the recent situation of oil and gas exploration across the world, and points out four key theoretical questions in unconventional oil and gas geology: (1) deeper understanding on "oil and gas system": "whole accumulation" mode of "whole oil and gas system" for petroliferous basins was proposed, the unconventional oil and gas accumulation mechanisms were analyzed by quantifying the generation, expulsion, migration, and accumulation; (2) fine grain sediments and tight facies sedimentology: by dissecting fine grain deposition and unconventional oil and gas generation, the integration points of three studies were put forward; (3) micro-to nano-pore system and fluid behavior in shale and tight reservoirs: five aspects of micro-to nano-pore system that should be focused in unconventional oil and gas study were proposed, and development features of micro-to nano-pores and fluid behavior in micro-to nano-pores were dissected; (4) unconventional oil and gas accumulation pattern and resource evaluation: starting from the features of unconventional oil and gas accumulation, the evaluation system for unconventional oil and gas resources were set up.

Key words: energy consumption structure, unconventional oil and gas, exploration situation, theoretical issues, petroleum system, tight facies, micro-to nano-pore system

摘要：

2012年常规能源燃料的消费量和生产量达到创纪录的历史最高水平，石油和天然气在能源消费结构中仍然占据主导地位，非常规油气产量的大幅上升使油气供需基本达到平衡。但目前对非常规油气还有很多重要的基础理论问题没有解决，对非常规油气的分布富集规律、勘探开发特点还没有把握。本文以此为出发点，回顾了近期全球油气勘探形势，提出了非常规油气地质学的4项重要理论问题：①"含油气系统"理论的深化再认识，提出了含油气盆地"全含油气系统"的"全过程成藏"模式，从烃类生-排-运-聚全过程定量化研究的4个关键问题出发，分析了非常规油气成藏机理；②细粒沉积体系与致密相带沉积学，通过解析细粒沉积与非常规油气生成关系的角度提出了3个研究结合点；③页岩与致密储层中微—纳米孔隙系统和流体相态，提出了微—纳米孔隙系统在非常规油气研究方面应重点关注的5个方面，并解析了微—纳米孔隙发育特点及微—纳米孔隙中流体相态的特征；④非常规油气富集规律与资源评价，从非常规油气聚集特征出发，优选建立了非常规油气资源评价方法体系。
