초록 ▼

A system is provided for the production of heavy crude oil from an undersea reservoir, and for the treatment of the crude oil to facilitate its transport. A floating body (12) which produces the heavy crude oil, carries a hydrocarbon cracking station (32) that cracks the heavy crude into light liquid and gaseous hydrocarbons, and that uses heat resulting from the cracking to produce pressured steam. The pressured steam is used to drive a steam-powered engine (72) (with pistons or a turbine) that drives an electrical generator (74) whose electricity powers the system.

대표청구항 ▼

1. A method for efficiently obtaining light oil from an undersea reservoir (14) which produces a produced fluid that contains heavy oil, comprising: passing said produced fluid from the undersea reservoir up from said reservoir through a riser (22) to a floating structure (12) that floats at a sea surface;passing said produced fluid to a separation station (36) on the floating structure, and, in said separation station separating the heavy crude oil of said produced fluid into hydrocarbons and non-hydrocarbon material, and separating the hydrocarbons into gaseous hydrocarbons, light oil, and heavy oil, including disposing of said non-hydrocarbon material into the sea;flowing said heavy oil to a hydrocarbon cracking station (32) on said floating structure wherein said hydrocarbon cracking station is energizable in part by electricity, and energizing said hydrocarbon cracking station to crack said heavy oil to produce light oil, gaseous hydrocarbons, and heat;using said heat produced by said hydrocarbon cracking station to energize a steam generator to produce pressured steam, using said pressured steam to drive a steam engine (72), using said steam engine to drive an electrical generator (74), and using a portion of electricity from said electrical generator to energize said cracking station. 2. The method described in claim 1 including: storing a quantity of heavy oil in a heavy oil buffer tank (60) that is connected to said cracking station,and flowing heavy oil from said oil buffer tank to said hydrocarbon cracking station in an amount that results in a constant flow of heavy oil to said hydrocarbon cracking station (32), andusing pressured steam from said steam generator to heat oil in said crude oil buffer tank, andcracking the oil in said cracking station before transporting it. 3. The method described in claim 1 wherein: said hydrocarbon cracking station has a heavy oil storage tank, and including using steam from said steam generator to heat heavy oil in said heavy oil storage tank before cracking the heavy oil and then transporting it. 4. An apparatus for producing hydrocarbons from an undersea reservoir which produces a produced fluid that contains heavy oil, comprising: a floating structure (12) that floats at sea surface, and a riser (22) that connects said reservoir to said floating structure;a separation station (36) on said floating structure which is coupled to said riser and which separates the heavy crude oil of said produced fluid into hydrocarbons and non-hydrocarbon material, and separates the hydrocarbons into gaseous hydrocarbons, light oil, and heavy oil, said separation station having a heavy oil outlet (51, 53) and said separation station uses electrical power;a cracking station (32) on said floating structure which is connected to a heavy oil outlet (53) of said separation station, said cracking station having a light oil outlet (61) and a steam outlet (70) and which is arranged to crack said heavy oil to produce light oil, gaseous hydrocarbons, and heat;an engine-generator set that receives heat from said cracking station to energize a steam generator to produce pressured steam to drive a steam engine and which uses the steam engine to drive an electrical generator (74), said electrical generator having an electrical outlet connected to said cracking station;wherein the cracking station is energized by using a portion of electricity from said electrical generator. 5. The apparatus described in claim 4 including: a buffer tank (60) which stores heavy oil and which has an inlet connected to said separation station to receive and store heavy oil therefrom and an outlet connected to said cracking station.
