| titleOfInvention | For the more solvent production practice of heavy oil reservoir |
| abstract | Disclose the multistep in-situ retorting technique of the use solvent for heavy oil reservoir, there is multiple step, comprise: remove solvent blocker from the region of contact heavy oil to cause space and to increase the interface zone unminding heavy oil of Solvent accessibilities, and in vapour form solvent is injected space to increase reservoir pressure until enough solvents exist to fill described space and the interfacial area contacting the increase of described heavy oil in liquid form.Then close described reservoir a period of time diffuses to unquarried oil from the gap of being filled by solvent through described interface zone to allow described solvent in maturation stage, to form the mixture of that viscosity reduces, solvent and oil and to measure one or more reservoir characteristic to determine the degree of the solvent dilution that unquarried oil has occurred in reservoir.Then, once described mixture has enough low viscosity be expelled to producing well to allow described mixture by described reservoir, start the production carrying out based on gravity drainage from described reservoir. |
