STUDYING THE PROCESSES OF EXTRACTION OF EXTRA-VISCOUS OIL BY HYDROCARBON SOLVENT
Abstract
Derived from the results of experimental modeling of physicochemical processes of solvent extraction of extra-viscous oil (EVO) from the reservoir model, the composition, which provides a 96% extraction of the oil from Ashal?chinskoe deposit, has been chosen. The composition represents the mixture of large-capacity petrochemical products. It includes the fraction of light aliphatic hydrocarbons, ethylbenzene distillation residue, and the mixture of aromatic hydrocarbons at a 0.50:0.25:0.25 ratio. The latter inhibited the asphaltene deposition in the drainage zone. As a model of the oil reservoir, a transparent chamber filled with the mixture of EVO and graded sand was used. The component compositions were compared according to the amount of extracted EVO, the rate of oil displacement, and accumulated oil recovery depending on the time and the volume of injected solvent, as well as according to the change of the fraction of EVO in the extracted product.
