Abstract
The utility model discloses a uniform dryness distributor for saturated vapor in an oil field. The uniform dryness distributor comprises a cyclone, a phase mixer and an uniform dryness distribution chamber which are sequentially connected, wherein the uniform dryness distribution chamber is connected with more than two branch pipes, flow rate regulation valves are arranged on the branch pipes, dryness flow rate meters are arranged on the branch pipes, and temperature sensors and pressure sensors are arranged on the branch pipes. The uniform dryness distributor has the advantages that a good distribution effect is realized, and the steam injection dryness of all wells is ensured to be uniform.
Description
Technical field
The utility model relates to petroleum industry and annotates vapour oil recovery field, and particularly a kind of oil field is with mass dryness fraction distributors such as saturated vapours.
Background technology
Liaohe Oil Field viscous crude, super-heavy oil deposit are mainly taked steam injection heating exploitation technology, and through exploitation for many years, most blocks have entered development phase middle and later periods.External viscous crude, super heavy oil development experience show that for the heavy crude reservoir of development phase middle and later periods, adopting steam flooding technology is to improve the comparatively effective method of oil recovery.Therefore, the scene often exists boiler to annotate vapour to 2～3 mouthfuls of wells simultaneously, or many phenomenons that injection boiler is whole steam injection pipe network steam supply, because the geological condition difference of each well, so that steam injection pressure has height to have is low, the gettering ability of each well there are differences.The well steam injection rate that gettering ability is strong is big, steam quality is also high; The well steam injection rate of vapor absorption capacity difference is little, and steam quality is low, and the result causes the thermal recovery effect extreme difference of well, influences rate of oil production, influences the raising of oil recovery factor.Therefore need steam distributor be installed at thermal production well mouth.
At present, the steam distributor of the thermal production well mouth of field by using has following several: " T " property distributor, saturated vapor " ball " type distributor.
In realizing process of the present utility model, the inventor finds that there is following problem at least in prior art: the distribution of steam quality still exists bigger mass dryness fraction to distribute deviation in actual applications, causes the saturated vapour maldistribution, directly influences the crude oil production effect.
The utility model content
The utility model is in order to solve the deficiencies in the prior art, and when providing a kind of injection boiler to annotate many mouthfuls of wells at the same time, the notes vapour mass dryness fraction that enters each well head distributes the oil field that equates with mass dryness fraction distributors such as saturated vapours.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of oil field is with mass dryness fraction distributors such as saturated vapours, comprise the cyclone that links to each other successively, mixed-phase device and etc. the mass dryness fraction distributor chamber, mass dryness fraction distributor chamber such as described connects plural arm.
Described arm is provided with flow control valve.
Described arm is provided with the mass dryness fraction flow meter.
Described arm is provided with temperature pick up and pressure sensor.
The beneficial effect of the technical scheme that the utility model embodiment provides is: device of the present utility model is in the viscous crude field recovery process, exists boiler to annotate the needs of production of vapour and a kind of integrated skid-mounted device that collects steam distribution, the metering of steam multi-parameter and transmission of developing to 2-3 mouth well simultaneously.By enforcement of the present utility model, reach the mass dryness fraction of respectively annotating the vapour well and distribute production purpose equal, that steam flow is accurately controlled, steam parameter is monitored in real time.It is good that device of the present utility model has distribution effects, guarantees that the notes vapour mass dryness fraction of every mouthful of well reaches consistent; Adopt the stream-liquid two-phase flow measurement structure simple, in light weight; The adjusting of flow control valve is stable, good linearity, easy operating; The skid structure of whole device employing activity, easy for installation, simple to operate.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, to do one to the accompanying drawing that uses among the embodiment below introduces simply, apparently, below listed accompanying drawing only be embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the device schematic diagram that the utility model embodiment provides.
In the accompanying drawing, the component list of each label representative is as follows:
1. cyclone, 2. mixed-phase device 3. waits the mass dryness fraction distributor chamber, 4. arm, 5. flow control valve, 6. mass dryness fraction flow meter.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of oil field is with mass dryness fraction distributors such as saturated vapours, comprise the cyclone 1 that links to each other successively, mixed-phase device 2 with etc. mass dryness fraction distributor chamber 3, connect plural arm 4 etc. mass dryness fraction distributor chamber 3; Be equipped with a flow control valve 5 and a mass dryness fraction flow meter 6 on each arm; Arm is provided with temperature pick up and pressure sensor.The mass dryness fraction of arm, flow, temperature and pressure can be realized real-time monitoring by the wireless public network data transmission technology.
Device of the present utility model roughly is made of three parts, comprises mass dryness fraction distributor, flow control valve, the real-time monitoring of steam multi-parameter and transfer of data such as steam.The structure of mass dryness fraction distributors such as steam be by cyclone, mixed-phase device, etc. the mass dryness fraction distributor chamber be connected to form successively; Boiler comes gas at first to enter cyclone to make steam produce rotation, the water, the vapour phase that reach in the steam are tentatively mixed, then steam enters mixed-phase device, vapour phase and water in the steam are mixed fully, reach the even mixed phase of steam, the mass dryness fraction distributor chamber such as enter then rapidly, waiting the mass dryness fraction distributor chamber to realize the mean allocation of mass dryness fraction.The arm that connects etc. the mass dryness fraction distributor chamber is used to connect different well heads.Steam is realized the adjusting of the steam flow of each well of arrival under the control of flow control valve.Going that measuring instrument is installed on the well lines, removing mass dryness fraction, flow, temperature, the pressure of well and carry the variation of heat situation with monitoring.The steam multi-parameter measuring instrument of two phase flow adopts simple in structure, the method of the single orifice plate noise of dependable performance, can realize the online in real time measurement of steam quality, flow, adopt GPRS (GeneralPacket Radio Service, GPRS) wireless public network data transmission technology to realize the real-time release of monitoring result simultaneously.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
