Abstract
During production of hydrocarbons, an oil-gas flow from a well bottom to a well-head is subdivided into a plurality of individual oil-gas flows which flow in a plurality of individual passages located side-by-side with one another.
Claims24
A method of production of hydrocarbons, comprising the steps of introducing into an oil well a production pipe having an inlet to be located substantially in a region of a well bottom and an outlet to be located substantially in a region of a well head, so that an oil-gas mixture flow flows from the inlet to the outlet of the production pipe;
- and increasing in the production pipe a resistance to movement of a gas phase relative to an oil phase of the oil-gas mixture by subdividing at least a portion of the production pipe into a plurality of passages each having a cross-section which is a fraction of a cross-section of the production pipe and extending in a direction from the inlet to the outlet of the production pipe so as to subdivide said oil-gas mixture flow into a plurality of individual oil-gas mixture flows which have a fraction of a cross-section of said oil-gas mixture and flow simultaneously in a direction from the inlet to the outlet of the production pipe.
A device for production of hydrocarbons, comprising a production pipe to be introduced into an oil well and having an inlet to be located in a region of a well bottom and an outlet to be located in a region of a valve well head, so that an oil-gas mixture flow flows from the inlet to the outlet of the production pipe;
- and means for increasing in said production pipe a resistance to movement of a gas phase relative to an oil phase of the oil-gas mixture, said increasing means include means for subdividing at least a portion of said production pipe into a plurality of passages having a reduced cross-section which is a fraction of a cross-section of said production pipe and extending from said inlet to said outlet of said production pipe, so as to subdivide said oil-gas mixture flow into a plurality of individual oil-gas mixture flows which have a fraction of a cross section of said oil-gas mixture and flow through said passages of said reduced cross-section simultaneously in a direction from said inlet to said outlet of said production pipe.
A method of production of hydrocarbons, comprising the steps of introducing into a well a production pipe having an inlet to be located substantially in a region of a well bottom and an outlet to be located substantially in a region of a well head, so that a liquid-gas mixture flow flows from the inlet to the outlet of the production pipe;
- and increasing in the production pipe a resistance to movement of a gas phase relative to a liquid phase of the liquid-gas mixture by subdividing at least a portion of the production pipe into a plurality of passages each having a cross-section area which is a fraction of a cross-section area of the production pipe and extending in a direction from the inlet to the outlet of the production pipe so as to subdivide said liquid-gas mixture flow into a plurality of individual liquid-gas mixture flows which have a fraction of a cross-section area of said liquid-gas mixture flow, said individual flows moving simultaneously in the direction from the inlet to the outlet of the production pipe.
A device for production of hydrocarbons comprising a production pipe to be introduced into a well and having an inlet to be located in a region of a well bottom and an outlet to be located in a region of a well head, so that a liquid-gas mixture flow flows from the inlet to the outlet of the production pipe;
- and means for increasing in said production pipe a resistance to movement of a gas phase relative to a liquid phase of the liquid-gas mixture, said means for increasing include means for subdividing at least a portion of said production pipe into a plurality of passages having a reduced cross-section area which is a fraction of a cross-section area of said production pipe and extending from said inlet to said outlet of said production pipe, so as to subdivide said liquid-gas mixture flow into a plurality of individual liquid-gas mixture flows which have a fraction of a cross section area of said liquid-gas mixture and flow through said passages of said reduced cross-section area simultaneously in a direction from said inlet to said outlet of said production pipe.
