中国页岩气勘探误区剖析

Analysis of Misunderstandings in the Exploration of Chinese Shale Gas

页岩气具有自生自储、低孔低渗的特点,以往对页岩气藏的评价通常局限于八大成藏地质要素,容易走进页岩气勘探的误区。本文从勘探开发模式、成藏机理、产业链布置等方面系统梳理与剖析了当前中国页岩气勘探过程中存在的八大误区,并提出从生烃、储层、盖层、圈闭、运移和保存条件等要素入手,才能确保页岩气勘探风险可控,为页岩气产业良性发展提供指导与借鉴。

Shale gas has the charaeteristics of self-generation and self-storage, low-pore and low-infiltration, but its eonventional evaluation is often limited to eight major geological reservoir-formation elements, which may easily lead to errors of shale gas exploration. From geological exploration and exploitation patterns, reservoir forming mechanism and industrial chain deployment, this paper has examined and analyzed eight major errors in Chinese shale gas prospecting, stated that the risk of shale gas prospecting can only be controlled from hydrocarbon generation, storage layers, covering layers, trap, transport and maintenance conditions, and offered constructive guidance and referenee to the positive industrial development of shale gas.
