The Research of Reservoir Forming Characteristics of Tight Sand Gas

摘要

Tight sand gas is one of unconventional gas. Under the condition of the gradual depletion of conventional resources, unconventional resource is gradually paid more attention. Tight sand gas is divided into two types: pre-exiting deep gas and subsequent tight sand gas on the foundation of current research. Different types of accumulations having various characteristics, so describing and contrasting reservoir forming characteristics of two types of tight sand gas, analyze reservoir forming rules are very important to guide natural gas exploration and production.
