Methods of producing alkylated hydrocarbons from a liquid produced from an in situ heat treatment

摘要

Disclosed is a method for producing alkylated hydrocarbons, which comprises: producing formation fluid from a subsurface in situ heat treatment process; separating the formation fluid to produce a liquid stream and a first gas stream, wherein the first gas stream comprises olefins having a carbon number of at least 3; fractionating the liquid stream to produce at least a second gas stream comprising hydrocarbons having a carbon number of at least 3, wherein fractionating the liquid stream produces hydrocarbon components with a boiling range distribution between 38 °C and 200 °C at 0.101Mpa known as naphtha, and blending the naphtha with the formation fluid to produce a blended fluid; introducing the first gas stream and the blended fluid into an alkylation unit to produce alkylated hydrocarbons.
