Abstract
Disclosed is a system for producing oil and/or gas from an underground formation comprising a first well above the formation; the first well comprises a mechanism to inject a miscible enhanced oil recovery formulation into the formation; the first well comprises a first tubular and a second tubular, the first tubular threadingly engaged with the second tubular; a thread compound disposed on at least one of a thread of the first tubular and a thread of the second tubular; the thread compound comprises an additive adapted to swell when exposed to the miscible enhanced oil recovery formulation.
Description
Technical field
The present invention relates to be used to produce oil and/or the system and method for gas.
Background technology
Improve oil recovery (EOR) and can be used for increasing the oil recovery in the global oil gas field.Three kinds of main types that improve oil recovery are arranged: heating power, chemical/polymer and gas inject; They can be used for increasing the oil recovery from reservoir, have surpassed the oil recovery that obtains through conventional method-possibly prolong the life-span of oil gas field and increase the oil recovery factor.
Heating power improves recovery ratio and carries out through adding heat to reservoir.Practice form is a steam flooding the most widely, and it has reduced oily viscosity, so that oil can flow to producing well.The chemical displacement of reservoir oil increases recovery ratio through the capillary thing active force that reduces to capture residual oil.Polymer displacement of reservoir oil has improved the displacement sweep efficiency that injects water.Can miscible injection work with the mode similar with the chemical displacement of reservoir oil.Through inject can be miscible with oil fluid, the residual oil that can gather and captured.
With reference to Fig. 1, show prior art system 100.System 100 comprises subsurface formations 102, subsurface formations 104, subsurface formations 106 and subsurface formations 108.Production equipment 110 is arranged on the place, ground.Well 112 passes stratum 102 and 104, and ends in the stratum 106.The part on stratum 106 is by 114 expressions.Oil gentle through well 112 from the stratum 106 outputs to production equipment 110.Gas and liquid are separated from each other, and gas is stored in the gas storage tanks 116, and liquid is stored in the fluid storage tanks 118.
A kind of sealed tubular joint that is used for the expanded radially of oil gas well is disclosed but publication number is the U.S. Patent application of US2005/093250; But said tubular configured joint has the tube element of a pair of expanded radially; Each tube element has screw thread at its free end; And being connected to each other flushes connection with formation, and this screw thread comprises: be positioned at contiguous at least free-ended hook-shaped incomplete thread; And sealer; The sealing thing extends between the screw thread of the screw thread of an element and another element and is attached to the screw thread of this element and the screw thread of this another element; Wherein after the expanded radially of a pair of element that has connected, the sealing thing remains on and extends between the screw thread of screw thread and another element of an element and be attached to the screw thread of this element and the screw thread of this another element.Sealing thing or be coated in the elastomeric sealant of the unlubricated oil on one or two of this a pair of element, or be applied to the simple metal on each of this a pair of element.Publication number is that the U.S. Patent application of US2005/093250 is incorporated in this paper with its full content by reference.
British Patent Application file GB-A 8253000033 discloses following content: screw rod, nut or spiro rod cap can be fixed in screw rod or the helicitic texture parts through the mixture of siloxanes that between screw thread, inserts a small amount of polymerization; Being screwed in a time-out elastic body at these parts is distributed between the screw thread; And subsequently because elastic body can flow these parts thereby adhesively combine when cold.In addition, the dimethyl polysiloxane of HMW can be dissolved in such as in aromatics or the chlorinated aliphatic hydrocarbon solvent, perhaps uses with the dispersion form, so that elastic body is incorporated between the screw thread of screw rod or nut.When solvent or dispersing agent evaporation, it will make the macromolecule dimethyl polysiloxane keep its original form.British Patent Application GB-A 8253000033 is incorporated in this paper with its full content by reference at this.
The publication number that is disclosed on November 16th, 2006 is US 2006/0254769 and to act on behalf of case number be that the U.S. Patent application common co-pending of TH2616 discloses a kind of system; This system comprises: be used for from the mechanism of subsurface formations recovery of oil and/or gas, this oil and/or gas bag are drawn together one or more sulfur-containing compounds; Be used for to convert to from least a portion of the sulfur-containing compound of oil of being gathered and/or gas the mechanism of carbon disulfide formulation; And the mechanism that is used at least a portion of carbon disulfide formulation is discharged into the stratum.Publication number is that the U.S. Patent application of US 2006/0254769 is incorporated in this paper with its full content by reference.
