Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the embodiment of the present invention is described in further details.At this, schematic description and description of the present invention is for explaining the present invention, but not as a limitation of the invention.
In the embodiment of the present invention, first well is judged qualitatively, the abnormal well of Preliminary screening.Fig. 1 is the schematic diagram of the recognition methods of the abnormal producing well of oil-gas reservoir in the embodiment of the present invention.As shown in Figure 1, in the embodiment of the present invention, the recognition methods of the abnormal producing well of oil-gas reservoir can comprise:
Step 101, strata pressure when going into operation according to well yield data and individual well, classify wells all in oil field;
Step 102, according to well production time, wells all in oil field to be divided into groups;
Step 103, dissimilar well is presented on corresponding map according to the different grouping of production time;
Step 104, relation by dissimilar well and map in the every picture group of contrast, determine the distribution characteristics of dissimilar well;
Step 105, distribution characteristics according to dissimilar well, identify abnormal producing well.
During concrete enforcement, strata pressure when first going into operation according to well yield data and individual well, classifies wells all in oil field.In embodiment, strata pressure when can go into operation according to well yield data and individual well, is divided into wells all in oil field: produce in high pressure high-yield well, high pressure in well, high pressure stripper well, low pressure high-yield well, low pressure and produce well and low-voltage and low-yield well; Wherein, for certain oil field, it is high-pressure well that strata pressure when individual well is gone into operation is greater than 4000psi, it is low pressure well that strata pressure when individual well is gone into operation is less than 4000psi, it is stripper well that well yield data are less than 2000 barrels/day (b/d), well yield data are greater than 2000 barrels/day and are less than 4000 barrels/day for middle product well, and well yield data are greater than 4000 barrels/day for high-yield well.Output criteria for classifying threshold value 4000 barrels/day wherein and 2000 barrels/day, pressure criteria for classifying threshold value 4000psi, all can be arranged according to actual needs, and concrete value is herein only an example, also can be set to other numerical value during enforcement.
In embodiment, can first by carrying out statistical analysis to well yield data all in oil field (initial production, First Year peak-production, First Year average product etc. can be comprised), determine the high, medium and low three class well criteria for classifying, all wells are divided into high, medium and low three class wells according to well yield data.Again based on the test pressure data of individual well, determine strata pressure when individual well is gone into operation.If individual well does not have initial pressure test data, the pressure testing data of well time difference in setting range around can be used, such as, use the pressure testing data of well similar time (as in half a year) around.When going into operation to individual well, strata pressure carries out statistical analysis, determines high pressure, the low pressure criteria for classifying, and all wells are divided into high-pressure well, low pressure well two class well according to the pressure condition of going into operation.Then, based on above-mentioned well classification result, all wells can be divided into six classes: produce in high pressure high-yield well, high pressure in well, high pressure stripper well, low pressure high-yield well, low pressure and produce well, low-voltage and low-yield well.Be illustrated in figure 2 certain oil field all producing well First Years daily average oil production and initial stage operation pressure dependence figure, output criteria for classifying threshold value is 4000 barrels/day and 2000 barrels/day, and pressure criteria for classifying threshold value is 4000psi (criteria for classifying threshold value can set as required).Based on output and the pressure criteria for classifying, well is divided into six classes.
During concrete enforcement, also according to well production time, wells all in oil field are divided into groups.Such as, surge well characteristic of production dynamic, according to the difference of well production time, is divided into multiple different groups by well, thus can show on different geological map the well in this group follow-up simultaneously.As shown in Figure 3, according to the difference of production time, all for certain oil field producing wells are divided into 5 groups.
After wells all in oil field being carried out classify and divide into groups, dissimilar well can be presented on corresponding map according to the different grouping of production time.Such as, according to the result of above-mentioned classification and grouping, six class wells are presented on corresponding map according to the different grouping of production time with dissimilar well symbol.Corresponding map mainly plays the map of the aspect such as geology, oil reservoir of major control to output, can include, but are not limited to constructional drawing, deposition phasor, effective thickness distribution map, formation capacity distribution map, current reservoir pressure figure etc.Have 5 groups of wells according to production time difference as shown in Figure 3, Figure 4 shows that the distribution situation of the dissimilar well of wherein first group of well, Figure 5 shows that the distribution situation of first group and second group well.In like manner, the distribution map of other group wells on different map can be made.
By contrasting the relation of dissimilar well and map in every picture group, the distribution characteristics of dissimilar well can be determined, according to the distribution characteristics of dissimilar well, identifying abnormal producing well.Abnormal producing well feature must be inconsistent with normal well, thus can identify; By the display of grouping map, the impact that different time is gone into operation on well production can be determined, thus eliminate inter-well interference and the low impact causing aspects such as yielding poorly of later stage brought in well pressure.
Can be found by the distribution characteristics of different groups of Fig. 4, Fig. 5 etc. and dissimilar well, the region that high-yield well multidigit is large in sandstone thickness, formation capacity is high, the region that middle product well multidigit is medium in sandstone thickness, formation capacity is medium, the stripper well region that then multidigit is thin in sandstone thickness, formation capacity is low.Independent again Fig. 4 to be analyzed, tentatively can judge that producing well in 3 mouthfuls of high pressure may be all abnormal well, because this position reservoir residing for 3 mouthfuls of wells is thick, formation capacity is high, consistent with the high-yield well feature of other positions in figure, should be high-yield well.But be analyzed by composition graphs 5, can find out that producing in the east around well that well is also mostly in 2 mouthfuls is middle product well, stripper well, and produce in 1 of west mouthful around well and be high-yield well, tentatively can determine that producing well is in the east abnormal well, producing well in west is normal well.Examine analysis to the relevant dynamic static data of three mouthfuls of wells further, confirm that producing well in two mouthfuls is in the east normal well, the why medium reason of output is that the just water breakthrough that drives a well soon causes output obviously to reduce because close to the water of limit.And why west well yields poorly because this well shaft wax deposition causes.In like manner, adopt and use the same method, also can carry out abnormal well to second group of producing well in Fig. 5 and other group producing wells and judge and analyze.By moving static data further combined with individual well, and above-mentioned qualitative method is adopted to carry out abnormal well analysis to all groups of producing wells, the abnormal producing well of preliminary identification.
During concrete enforcement, after the abnormal producing well of above-mentioned qualitative judgement, static data and quantitative analysis judged result can be moved in conjunction with individual well, finally determine abnormal producing well.In embodiment, adopt quantitative method to judge the abnormal well of production, can comprise: the graph of a relation drawing individual well daily output and individual well formation capacity; The output of producing profile testing and the respective counts strong point of well formation capacity is drawn in described graph of a relation; With producing profile testing data point fluctuation range determination reference range, in described graph of a relation, determine abnormal producing well.Follow-up being combined with the abnormal producing well of the distribution characteristics identification according to dissimilar well by the abnormal producing well determined in described graph of a relation is analyzed, finally determine abnormal producing well, thus the abnormal well analytical method of aggregate qualitative and quantitative abnormal well analytical method carry out the identification of abnormal producing well.
Such as, draw individual well First Year rush day output, the initial daily oil production of individual well, First Year average daily production, average daily production and rush day output and the graph of a relation (average daily production and rush day output refer to the average daily production that the whole production history of individual well is corresponding and rush day output) of individual well formation capacity, in figure, draw the output of producing profile testing and the respective counts strong point of well formation capacity simultaneously.With producing profile testing data point fluctuation range determination reference range, the normal producing well of possibility can be determined from figure, and possible abnormal producing well.Be respectively the graph of a relation of the producing well First Year rush day oil production in certain oil field and the graph of a relation of individual well formation capacity and initial daily oil production and individual well formation capacity as shown in Figure 6, Figure 7.In figure, low KH high-yield well and high KH stripper well may be all abnormal producing well, and mid portion well may be then all normal well.And determine whether abnormal well further, also need again further combined with the dynamic static data of individual well and the result of qualitative judgement.By to likely abnormal producing well analyze, eliminate part low KH high-yield well be due to these wells only have spontaneous potential curve cause explain shale content obviously higher (spontaneous potential curve Explanation Accuracy is starkly lower than gamma ray curve), thus cause explain well formation capacity KH obviously on the low side.Remain other most of low KH high-yield wells and high KH stripper well is abnormal well, and abnormal cause comprises a variety of causes such as pipe is altered outward, production split mistake, shaft bottom pollution.
Above-described embodiment describes in detail to the identification step of the abnormal producing well in oil field by quantitatively and qualitatively method, after excluding abnormal well, just can be analyzed accordingly remaining normal well and study.If above-mentioned oil field is after excluding abnormal well, find there is relation very clearly between the high, medium and low three class wells of normal producing well and the maximum perforation thickness of well and accumulation perforation thickness, and by this relation, Accurate Prediction has been carried out to full oil reservoir diverse location well yield height, direct the well site deployment of new well.If do not remove abnormal well, be then difficult to find this relation.
