Abstract:

Longwangmiao Formation gas reservoir in the Gaoshiti-Moxi area is currently the focus of petroleum exploration and development in Sichuan Provence.The reservoir has dissolved pores and contains asphalt.In usual experiment,plenty of dissolved pores which developed around core’s surface can’t be saturated by salt water and thus can’t be detected by NMR.What’s more,we found NMR signal in dry core samples.After quantities of comparison experiments of pure asphalt and mixture of asphalt and sand,we confirm the NMR signal in dry core sample comes from asphalt.We develop a calibration method of dissolved pores around surface and asphalt NMR signal in dry core sample.The result shows that after calibration,the NMR porosity has better agreement with helium porosity and NMR bound water saturation has better agreement with weighing method.T2 cutoff value can’t be influenced by dissolved pores around surface but must be through asphalt NMR signal calibration.The data through calibration can characterize the fluid’s and pore’s information of the reservoir more precisely.

Key words: Gaoshiti-Moxi area, Nuclear magnetic resonance, Dissolved pores, Asphalt
