567-579
Distribution of high quality diagenetic facies is controlled jointly by sedimentary facies, diagenesis and pore structure, and especially throat distribution is the main factor for controlling sandstone reservoir permeability. Reservoir in the hydromica cementation--residual intergranular pore facies and hydromica cementation--feldspar corrosion facies is distributed mainly in semi-deep lacustrine gravity flow composite channel turbidites; fine--tiny throats are developed, the connectedness of pore throats is good, and their percolation capacity is the best; oil and water are of relatively uniform seepage flow, and the oil and gas in pores are produced via throats extremely easily. The reservoir in the chlorite cementation facies and hydromica cementation weak corrosion facies is located in the margin of branch channels and distributed in island shape; the pore throat radius is small but is distributed uniformly, and the percolation capacity of pore throats is medium to bad. Reservoir in the carbonate cementation facies and carbonate + hydromica cementation facies is developed mainly between branch channels; the development degree of the pore structure is low, throats are fine and small, and pore throat connectedness is bad; the oil and gas rich in pores are difficult to pass small throats, and the recovery ratio is low. |
