| titleOfInvention | A Method for Realizing Oil Displacement with Variable Seepage Resistance |
| abstract | The present invention relates to a method for realizing variable seepage resistance oil displacement. This method for realizing variable seepage resistance oil displacement: 1. Aiming at vertically heterogeneous reservoirs for actual reservoirs, testing the reservoirs of different permeable layers Structural parameters: 2. Combined with the fracture pressure, injection pressure and pressure gradient of the actual reservoir, carry out the propulsion matching monitoring experiment of different injection systems under different pore throat conditions, and evaluate the injection capacity of different injection systems: 3. Determine the variable seepage resistance flooding The type and sequence of the injection system that the oil needs to be injected to realize the near-parallel advancement of the displacement front: 4. Carry out variable seepage resistance flooding and evaluate the effect. The invention can not only test the position of the displacement front of different displacement agent systems in different permeable layers, but also provide reference for the design of variable seepage resistance flooding scheme, and then realize variable seepage resistance flooding, and more importantly, can realize displacement The leading edge advances nearly in parallel, thereby greatly increasing the ultimate recovery factor. |
