A certain block of oil and gas accumulation understanding
No.5 Production Plant, Daqing Oil Field, China
The block is located in the southern part of an oil field. A grooved area held by three structures. The blank area is 41.6 square kilometers. It accounts for about 20% of the blank area. The faults in this area are more developed, mainly in the NNW direction, Permeability 0.7~1542mD, The average is 275.1mD, the porosity is 11.1~27.8%, the average is 23.2%, the average effective thickness is 2.2m, and the river channel width is 100-300m. The three-dimensional seismic data were collected in 2004, the accuracy of the survey network was 20m×40m, the number of coverage times was 66 times, the main frequency was 39-42Hz, the surface element was 10m×10m, and the data was finely processed and explained in 2008.
Key words: Oil and gas accumulation / Sedimentary facies / Trapping
