Abstract
The utility model provides an underground water-gas mixer which is characterized in that a water-gas mixture firstly enters an underground axial-flow type water-gas rotating separator, the separated water enters a liquid storage bin, the separated water vapor flows downwards from a central tube into a spray tube; when the water vapor flows out from the spray tube at high speed, the water in the liquid storage bin can be sucked out by a throttle ring so as to form a vaporific mixture. The underground water-gas mixture disclosed by the utility model has the advantages of simple structure, low cost, obvious effect, and the like.
Description
Technical field
The utility model relates to a kind of device of heavy crude reservoir steam injection oil recovery by heating, particularly a kind of device of realizing that down-hole steam mixes.
Background technology
China has abundant spy, super viscous crude resource at present, steam injection is the important means of exploitation viscous crude, but because vertical development degree that vapour, water gravitational differentiation, steam overlap and channelling cause is inhomogeneous, restricting the further raising of thermal recovery recovery ratio in the peupendicular hole steam injection process.
From the very long notes steam pipe road of water vapour process on ground, heat and energy loss are very big, therefore, may have multiple flow pattern in the shaft bottom gas-vapor mix, such as stratified flow, bubble flow and slug flow etc.It is very poor to use common static mixer mixed effect under some flow pattern, the ability that conforms.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of mine water steam mixer.
Technical solution adopted in the utility model is: a kind of mine water steam mixer, comprise top connection, plug, guide ring, central tube, jet pipe wiper block, jet pipe locating piece, lower contact composition, the box of described top connection is that tubing thread links to each other with the top oil pipe, the bottom links to each other with shell, and the top connection end is as the positioning step of guide ring; Conically shaped is installed in the enclosure, sets upright, feels relieved by the conically shaped wiper block in the bottom; Guide ring is installed in the conically shaped top by screw thread, and guide ring endoporus top is sealed by plug, and below and central tube are by being threaded, and step is arranged at central tube top, with the guide ring bottom fixedly water conservancy diversion leaf of coming together; The central tube top is equipped with air inlet, and the gas of separating enters the jet pipe in downstream via centre bore, central tube, adapter; Have outage on the conical surface of conically shaped bottom, the liquid separated enters through outage, conically shaped wiper block, jet pipe wiper block in the liquid storage cabin of below, guarantees concentric by the centralizing function of taking between conically shaped and the central tube; Jet pipe links to each other by screw thread with the jet pipe wiper block and shell keeps concentric, inside links to each other with the upstream central tube by taking over, annular space between jet pipe and the shell forms the liquid storage cabin, the size in liquid storage cabin is determined by the length of jet pipe, gas from central tube sprays at a high speed through the taper contracting noz(zle) bottom the jet pipe, produce the liquid sucking-off of low-pressure area at the restrictor ring place, thereby form vaporific gas-vapor mix inside, liquid storage cabin; Jet pipe bottom cylindrical has step, be used for locating jet pipe mutually with the jet pipe locating piece, jet pipe locating piece bottom contacts with the mixed block upper end, regulates the size that the thickness of jet pipe locating piece can be regulated restrictor ring, lower contact compresses the mixed block of its top, links to each other with the below tubing string simultaneously.
Air inlet is arranged at the central tube top in the axial-flow type steam rotary separator of described down-hole; The conically shaped bottom has outage.
The beneficial effects of the utility model are: simple in structure, cost is low, effect is obvious, the utility model employing separates earlier the mode of afterwards mixing and carries out the steam mixing, liquid storage and imbibition are leading and stagnant latter two interlaced processes, air content hour in gas-vapor mix, the water water vapours many, the nozzle of flowing through that enter in the liquid storage cabin are few, therefore liquid absorption is few, has liquid remnants in the liquid storage cabin; When air content was big in the gas-vapor mix, the water that enters in the liquid storage cabin was few, and the water of gas flow rate height sucking-off from the liquid storage cabin of the nozzle of flowing through is just many; Guarantee that by the size of regulating restrictor ring the ratio of gas-vapor mix keeps constant substantially.
