ABSTRACT:
Substances to stimulate the extraction of crude oil and a method, of processing them: This invention is about substances to stimulate the extraction of crude oils, especially the ponderous and paraffin one, not clogging the route and the abutting deposits of the oil derrick by changing the deposit's reology and also about solubility of the aggregates which were made from paraffin resins on the oil derrick's circulation route, using a similar chemical vector to the prodrugs from the medicine industry. The substance to stimulate the extraction of crude oil by increasing the fluidization characterized by the fact that 90% from the volume is made by mixing three fractions oil types from the distilled mineral coal: −20-30% phenol oil (fraction distilled from 170-190° C.); −20-40% absorption oil (fraction distilled from 250-270° C.); −20-40% polymerized oil (fraction distilled from 320-350° C.); which is called chemical vector and till 100% is completing itself with organic reactive like solvents, active-tensioned substances, generating gas substances.
