Description
Technical field
The present invention relates to a kind of well choosing method, and in particular to open the well choosing method of production between a kind of low yield liquid measure oil well.
Background technology
It is that domestic hyposmosis, ultra-low penetration oil field carry the major measure hand for imitating consumption reduction at present that production is opened between low liquid measure oil well
Section, the subject matter for facing is a choice-start well problem, i.e., production liquid measure boundary is opened between oil well and determines problem.Literature survey, scene
Investigation finds mainly have following several to open well choosing method at present：One is produced on-site empirical method, i.e., according to oil well actual production
Situation, summarizes well mouth of oil well and goes out liquid law characteristic, substantially determines oil well effective production time, enters in the ranks and opens production, it is clear that be this
Method error is larger, is influenceed by the experience managerial skills height of live oil recovery workman, and the specific implementation amount of getting up to work is big；Two are
Representative oil well is chosen, well head is carried out and is continuously dynamically tested, grope build-up of fluid rule in oil well liquid output rule or pit shaft
Rule, is qualitatively judged, and is opened production between determining oil well and is selected well；The workload of this mode is big, costly, operational not strong；Three
It is that, based on oil well digital management system, continuous acquisition oil well production indicator card judges oil well supply and discharge rule, qualitative determination oil well
Between choice-start well, although this mode has certain reliability, workload is big, with the proviso that setting up in oil field digital management
Or work(figure meter is produced in system-based, is existed compared with big limitation.
The content of the invention
Shortcoming it is an object of the invention to overcome above-mentioned prior art, there is provided open production between a kind of low yield liquid measure oil well
Well choosing method, the method opens the well that selects of production between can realizing low yield liquid measure oil well, and reliability is higher, operation more letter
It is single.
The well choosing method for opening production between above-mentioned purpose, low yield liquid measure oil well of the present invention to reach includes following step
Suddenly：Calculate the extraction ability Q of low yield liquid measure oil wellAdopt, further according to the extraction ability Q of low yield liquid measure oil wellAdoptOil well is set up for adopting flat
Weigh equation, and then the actual production information according to low yield liquid measure oil well solves oil well for adopting equilibrium equation, obtains low yield liquid measure oil well
Theoretical Liquid output, the actual Liquid output of theoretical Liquid output and low yield liquid measure oil well finally according to low yield liquid measure oil well carries out low
That production is opened between Liquid output oil well selects well.
When low yield liquid measure oil well actual Liquid output more than or equal to low yield liquid measure oil well theoretical Liquid output when, then the low yield
Liquid measure oil well should not be needed into the ranks opening production.
When low yield liquid measure oil well actual Liquid output less than low yield liquid measure oil well theoretical Liquid output when, then the low yield liquid measure
Oil well is needed into the ranks opening production.
The extraction ability Q of low yield liquid measure oil wellAdoptExpression formula be：

The invention has the advantages that：
The well choosing method of production is opened between low yield liquid measure oil well of the present invention in concrete operations, using theoretical calculation with
The mode that produce reality is combined opens the well that selects of production between carrying out low yield liquid measure oil well, specifically first calculate low yield liquid measure oil well
Extraction ability, then calculates the theoretical Liquid output of low yield liquid measure oil well using oil well for adopting equilibrium equation, then will be according to low yield liquid
The theoretical Liquid output of gauging well and the actual Liquid output of low yield liquid measure oil well open the well that selects of production between carrying out low yield liquid measure oil well, behaviour
Make simple, convenient, reliability is higher, provided to open production between hyposmosis, ultra-low penetration oil field low yield liquid measure oil wells in field scale
Well means are selected, well choosing method deficiency is opened between efficiently solving the problems, such as at present, for oil field cost efficiency, benefit exploitation provide theory
Foundation, has important practical significance to oil field production.
Brief description of the drawings
Fig. 1 be open production in embodiment one between low yield liquid measure oil well select well figure.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
With reference to Fig. 1, the well choosing method that production is opened between low yield liquid measure oil well of the present invention is comprised the following steps：Calculate low
