When it is implemented, strata pressure when first being gone into operation according to well yield data and individual well, all wells in oil field are entered
Row classification.In embodiment, strata pressure when can be gone into operation according to well yield data and individual well, by all wells in oil field point
For：Produced in high pressure high-yield well, high pressure and well and low-voltage and low-yield well are produced in well, high pressure stripper well, low pressure high-yield well, low pressure；Wherein, with
Exemplified by certain oil field, it is high-pressure well that strata pressure when individual well is gone into operation, which is more than 4000psi, and strata pressure during individual well operation is less than
4000psi is low pressure well, and well yield data are stripper well less than 2000 barrels/day (b/d), and well yield data are more than 2000
Bucket/day and be middle production well less than 4000 barrels/day, well yield data are high-yield well more than 4000 barrels/day.Yield division therein
Barrel/day of standard threshold value 4000 and 2000 barrels/day, pressure criteria for classifying threshold value 4000psi, can according to be actually needed into
Row is set, and specific value herein is only one, can also be set to other numerical value during implementation.
In embodiment, can first pass through (may include initial production, First Year peak to all well yield data in oil field
Yield, First Year average product etc.) statistical analysis is carried out, the high, medium and low three classes well criteria for classifying is determined, according to well yield number
High, medium and low three classes well is divided into according to by all wells.Test pressure data based on individual well again, determine stratum when individual well is gone into operation
Pressure.If individual well does not have initial pressure test data, pressure test number of the surrounding well time difference in setting range can be borrowed
According to, such as borrow the pressure testing data of surrounding well similar time (such as in half a year).Strata pressure is united when being gone into operation to individual well
Meter analysis, determines high pressure, the low pressure criteria for classifying, all wells is divided into high-pressure well, low pressure well two according to the pressure condition of operation
Class well.Then, based on above-mentioned well classification result, all wells can be divided into six classes：Well, high pressure are produced in high pressure high-yield well, high pressure
Well, low-voltage and low-yield well are produced in stripper well, low pressure high-yield well, low pressure.It is illustrated in figure 2 all annuals of producing well first in certain oil field
Daily oil production and operation at initial stage pressure dependence figure, yield criteria for classifying threshold value are 4000 barrels/day and 2000 barrels/day, and pressure is drawn
The quasi- threshold value of minute mark is 4000psi (criteria for classifying threshold value can be set on demand).Based on yield and the pressure criteria for classifying by well
It is divided into six classes.
When it is implemented, always according to well production time, all wells in oil field are grouped.For example, surge well production is dynamic
State feature, according to the difference of well production time, well is divided into multiple different groups, so as to can subsequently exist to the well in the group
Carry out showing simultaneously on different geological maps.As shown in figure 3, all producing wells in certain oil field are divided according to the different of production time
For 5 groups.
After all wells are classified and are grouped in by oil field, different type well can be divided according to the difference of production time
Group is shown on corresponding map.For example, according to the result of above-mentioned classification and packet, by six class wells with different type well symbol according to
The different grouping of production time is shown on corresponding map.Corresponding map is mainly geology, the oil reservoir that major control is played to yield
Etc. map, it may include but be not limited to structural map, deposition phasor, effective thickness distribution map, formation capacity distribution map, mesh
Preceding reservoir pressure figure etc..5 groups of wells are shared according to production time difference as shown in Figure 3, Fig. 4 show wherein first group of well not
The distribution situation of same type well, Fig. 5 show the distribution situation of first group and second group well.Similarly, other group of well can be made
Distribution map on different maps.
By contrasting the relation of different type well and map in every group of figure, you can the distribution characteristics of different type well is determined,
According to the distribution characteristics of different type well, abnormal producing well is identified.Abnormal producing well feature must be inconsistent with normal well, so as to
It can be identified；Shown by being grouped map, it may be determined that different time is gone into operation influence to well production, so as to eliminate between well
Interference and the low influence for causing to yield poorly etc. of later stage operation well pressure.
By the distribution characteristics of different groups of Fig. 4, Fig. 5 etc. and different type well it can be found that high-yield well is more thick positioned at sandstone
The region that degree is big, formation capacity is high, middle production well is more positioned at the region that sandstone thickness is medium, formation capacity is medium, and stripper well is then
It is be located at the region that sandstone thickness is thin, formation capacity is low more.Individually Fig. 4 is analyzed again, can tentatively judge to produce well in 3 mouthfuls of high pressures
All it is probably abnormal well, because the location of this 3 mouthfuls of wells reservoir is thick, formation capacity is high, with the high yield in figure at other positions
Well feature is consistent, it should is high-yield well.But by being analyzed with reference to Fig. 5, it can be seen that produce well around well in 2 mouthfuls of east
It is middle production well, stripper well mostly, and it is high-yield well to be produced in 1 mouthful of west around well, can primarily determine that and well is produced in east as exception
Well, it is normal well that well is produced in west.Further dynamic static data related to three mouthfuls of wells carries out verification analysis, confirms in two mouthfuls of east
The reason for production well is normal well, and why medium yield is is that the just water breakthrough that drives a well soon causes yield obvious because nearer from side water
Reduce.And it is because caused by the well shaft wax deposition that why west well, which yields poorly,.Similarly, also can be right using same method
Second group of producing well and other group of producing well carry out abnormal well judgement and analysis in Fig. 5.By further combined with individual well sound state
Data, and abnormal well analysis is carried out using above-mentioned qualitative method to all groups of producing wells, tentatively identify abnormal producing well.
When it is implemented, after above-mentioned qualitative judgement exception producing well, individual well can be combined and move static data and quantitative point
Judged result is analysed, finally determines abnormal producing well.In embodiment, judged using quantitative method producing abnormal well, can
With including：Draw the graph of a relation of the individual well daily output and individual well formation capacity；Producing profile testing is drawn in the graph of a relation
Yield and the respective counts strong point of well formation capacity；Reference range is determined with producing profile testing data point fluctuation range, described
Abnormal producing well is determined in graph of a relation.Subsequently by the abnormal producing well determined in the graph of a relation and according to different type well
The abnormal producing well of distribution characteristics identification, which is combined, to be analyzed, and abnormal producing well is finally determined, so as to the exception of aggregate qualitative
Well analysis method and quantitative abnormal well analysis method carry out the identification of abnormal producing well.
For example, draw the individual well First Year peak daily output, the initial daily oil production of individual well, the first average annual daily volume, average
(average daily production refers to individual well with the peak daily output and entirely produced the graph of a relation of the daily output and the peak daily output and individual well formation capacity
Average daily production corresponding to history and the peak daily output), the yield and well formation capacity of producing profile testing are drawn in figure simultaneously
Respective counts strong point.Reference range is determined with producing profile testing data point fluctuation range, you being determined from figure may be normal
Producing well, and possible abnormal producing well.It is respectively the producing well First Year rush day oil-producing in certain oil field as shown in Figure 6, Figure 7
Amount and the graph of a relation of individual well formation capacity and initial daily oil production and the graph of a relation of individual well formation capacity.In figure low KH high-yield wells with
High KH stripper wells may be abnormal producing well, and center section well may all be then normal well.And further determine whether to be different
Chang Jing, it is also necessary to further with reference to the dynamic static data of individual well and the result of qualitative judgement.By to be possible to abnormal raw
Production well is analyzed, and it is due to that these wells only have the shale explained caused by spontaneous potential curve to eliminate the low KH high-yield wells in part
Content is obvious higher (spontaneous potential curve Explanation Accuracy be significantly lower than gamma ray curve), so as to causing the well of explanation series of strata
Number KH is substantially relatively low.Other remaining most of low KH high-yield wells and high KH stripper wells are abnormal well, and abnormal cause includes pipe
Alter outside, production split mistake, shaft bottom pollution etc. a variety of causes.
Above-described embodiment describe in detail by it is quantitative and qualitatively method to the identification step of oil field exception producing well, when
, can be with to remaining normal well progress analysis accordingly and research after excluding abnormal well.As above-mentioned oil field exclude it is different
Chang Jinghou, find have between the maximum perforation thickness and accumulation perforation thickness of the high, medium and low three classes well and well of normal producing well
The relation being apparent from, and Accurate Prediction has been carried out by the full oil reservoir diverse location well yield height of the relation pair, is directed
The well site deployment of new well.It is difficult to find this relation if not removing abnormal well.
