D1, encrypt back viscous crude dissolved gas drive experiment then; In said early stage of encrypting back viscous crude dissolved gas drive experiment; Make any outlet output of said viscous crude sample from said two outlets, measure the pressure variation in the said fill out sand tube, the oil mass and the dissolving tolerance of output;
D2, the later stage that the viscous crude dissolved gas drive is tested after said the encryption then make said viscous crude sample from two said ends outlet while outputs, measure the oil mass and the tolerance of each said end outlet output respectively.
10. viscous crude dissolved gas drive as claimed in claim 5 is encrypted the exploitation physical simulation experiment method, it is characterized in that, said viscous crude dissolved gas drive is encrypted the exploitation physical simulation experiment method and is specially:
Fill the quartz sand of certain voids volume in A3, the model in fill out sand tube, said fill out sand tube has two end outlets, in the model of fill out sand tube, injects the viscous crude sample of 2 times of said voids volumes then;
B3, then encrypt before viscous crude dissolved gas drive experiment; Make the outlet output of said viscous crude sample from the outlet of said two ends; Measure the pressure variation in the said fill out sand tube, the oil mass and the dissolving tolerance of output, in said fill out sand tube, stop till produce oil and the aerogenesis;
C3, clean said fill out sand tube and model and repeating step inject 2 times of said voids volumes in the model of fill out sand tube viscous crude sample then;
D3, encrypt back viscous crude dissolved gas drive experiment then, from first eventually, make said viscous crude sample, measure oil mass and tolerance that two said ends export outputs respectively from two said ends outlets outputs simultaneously from the viscous crude dissolved gas drive experiment of said encryptions back.
