Measuring point 3, measuring point 4, measuring point 7, the flow of measuring point 8 and measurement of water ratio value are assigned to the corresponding bottom for explaining interval, as solution
Release the flow and moisture content of the bottom of interval.
S2-3：Can be as an adjacent upper explanation using the measuring point during such as fruit dot depth measurement degree among certain perforation layer
The bottom of interval is deep, while this depth measurement degree is deep as the top of next explanation interval.Specifically, Fig. 3 can be referred to, survey is utilized
No. 1 perforation floor is divided into two explanation intervals up and down by point 2, wherein, the bottom depth of the explanation interval of top is the depth of measuring point 2, under
The top depth of the explanation interval of side is the depth of measuring point 2.It is similar, can also utilize measuring point 5, measuring point 6 by No. 3 perforation floor be divided into it is upper in
Lower three explanations interval；And the flow of above-mentioned measuring point and water cut value are assigned to the corresponding top layer or bottom for explaining interval.
For example, the flow of bottom of interval and aqueous can be explained using the flow of measuring point 2 and water cut value as top in No. 1 perforation floor
Rate value, the flow and water cut value of the top layer of interval are explained using the flow of measuring point 2 and moisture content as lower section in No. 1 perforation floor.
S3：According to the rule described in S2, top of the measuring point successively with the perforation layer of whole is carried out deeply the bottom of with deeply from top to bottom
Contrast, until whole measuring points judge to finish, the explanation interval top sorted out is ranked up with bottom point deeply according to ascending deeply,
In the bottom position increase perforation bottom depth point of last explanation interval after sequence.Specifically, Fig. 3 can be referred to, respectively
It is individual to explain that interval depth point (including each top layer for explaining interval, each bottom for explaining interval) is followed successively by from top to bottom：No. 1
The top depth of perforation floor, the depth of measuring point 2, the bottom of No. 1 perforation floor is deep, the top of No. 2 perforation floor is deep, the bottom of No. 2 perforation floor is deep, No. 3
The top depth of perforation floor, the depth of measuring point 5, the depth of measuring point 6, the bottom of No. 3 perforation floor is deep, the top of No. 4 perforation floor is deep, No. 6 perforations
The bottom of floor is deep, the top of No. 7 perforation floor is deep, and deep for last bottom in the bottom of lowermost end No. 8 perforation floor of increase；According to measuring point
Data, above-mentioned each depth point, i.e., the top layer of each explanation interval and the flow and water cut value of bottom are determined, wherein, No. 8 are penetrated
The flow of the bottom of aperture layer can be entered as zero, and other explain that the flow of interval depth point and water cut value can be according to corresponding
The flow and water cut value of measuring point determine.
S4：Determine each explanation interval.
Sorted out from the explanation interval depth point of arrangement, the top of interval (is explained in upper and lower two adjacent depth points
Layer and the bottom for explaining interval) as an explanation interval.Wherein, it is equal to deeply in perforation layer the bottom of with if explaining that the top of interval is deep
When the bottom depth and the top depth of next perforation layer of a upper perforation layer, using the explanation interval as explanation of error interval is divided, i.e.,
Invalid explanation interval, and then the explanation interval can be removed.Fig. 3 can be specifically referred to, is removed respectively deep by the bottom of No. 1 perforation floor
The nothing that the invalid explanation interval that is formed deeply with the top of No. 2 perforation floor, the bottom of No. 2 perforation floor be deep and the top of No. 3 perforation floor forms deeply
Effect explains the bottom depth of the invalid explanation interval that interval, the bottom of No. 3 perforation floor be deep and the top of No. 4 perforation floor forms deeply, No. 6 perforation floor
The invalid interval formed deeply with the top of No. 7 perforation floor.It can finally determine accurately to explain interval.
S5：The aquifer yield and oil production of each explanation interval are determined respectively.
According to measuring point data, the flow value of the two neighboring measurement point of measuring point 1 to 8 is subtracted each other to obtain corresponding explanation interval
Liquid output, above-mentioned each Liquid output for explaining interval is multiplied by the corresponding moisture content for explaining interval respectively and obtains corresponding explanation interval
Aquifer yield, subtract the corresponding aquifer yield for explaining interval using the Liquid output of each explanation interval and obtain the production of each explanation interval
Oil mass.
By above-mentioned Sample Scenario, the determination method and apparatus for explaining interval that the application embodiment provides are demonstrated,
By the way that a survey data and perforation data are combined, according to unified preset rules, multiple explanation intervals are marked off；Recycle point
Aquifer yield, oil production that data determine each explanation interval respectively are surveyed, can solve to be determined present in existing method really
Explain interval is inaccurate, error is larger technical problem, the explanation for accurately and rapidly determining target area can be reached really
The technique effect of interval.
