In order to restrict injection water flowing through high-permeability zones and improve fluid flow field in water flooding reservoirs,a kind of flexibile agent SR-3 was developed for getting diversion of deep flooding fluid.

The effects of particle diameter,particle density,nozzle diameter,jet gas velocity,and static bed height on penetration depth were discussed in detail.

5 meter diameter semicircular jetting fluidized bed with 42?mm diameter semicircular nozzle,the transition of flow regime and the penetration depth were investigated.

Experimental results indicated that penetration depth increased with increasing jet gas velocity,while penetration depth decreased with decreasing nozzle pitch.

Present research status of the deep fluid and their effectiveness on oil/gas generation

The calculation of runoff depth for hydrological forecast was made by auto calculating function of Excel 2003 and IF function statement of computer.

Based on the observation and statistics of soil erosion and water loss in the sloping field,it is clear that the runoff depth and erosion would change along with the gradient,farming measures and vegetation.

The result shows that the higher the river network fractal dimension is,the more complex the river network will be,which is represented by higher Hurst exponent of runoff depth,so the runoff process is more simple.

The two faults and longitudinal axial fault in the central basin is the main channel for deep fluid,so they are important tectonic information about deep fluid mineralization.

The deep fluid is a fluid of high temperature and high pressure from the depths, which contains a great quantity of mineralizers such as Cl -,CO 2 and S 2- .
