Analysis on Relationship between Igneous Lithofacies Types and Oil and Gas Reservoir

Igneous reservoirs have become the focus of petroleum exploration,and igneous reservoir of saving oil and gas also has its own characteristics.According to the operability and practicality of igneous reservoir research expounds the common lithofacies types of igneous rock and the corresponding characteristics and discusses them by divided into two categories,eight lithofacies.Meanwhile,combining the domestic various igneous reservoirs have been found,analyzes the main facies belt of the favorable reservoir;Among them,the favorable reservoirs are mainly concentrated in the central face of shallow intrusive rocks,the upper and the lower sub facies,explosive facies,inner sub facies of the approaching out facies,the explosive breccias sub facies of volcanic conduit facies and so on in the extrusive rock.
