MICRO-ANALYSIS AND ITS APPLICATION OF OIL AND GAS RESERVOIR CHARACTERISTICS

The micro-analysis of mineral genesis,deposition environment and diagenesis process of oil and gas reservoir has played an important role in the quality evaluation of carbonate and clastic rock reservoirs.It is used in the research of clay mineral swelling and evolution in hydrocarbon zone protection and field exploration.The ESEM deals with samples bearing oil or water,hence reveals the changes of mineral rock more precisely.From the aspects of reservoir diagenesis,clay mineral characteristics and micro-pore generation,it is discussed in this paper the application of SEM/ESEM/EDX as modern testing technology in petroleum exploration and production.
