Brief description of the drawings
Fig. 1 is thermal production well and the cold change curve adopted between the bottom hole temperature (BHT) of well and time.
Specific embodiment
Experimental technique used in following embodiments is conventional method unless otherwise specified.
Material used, reagent etc. in following embodiments, unless otherwise specified, commercially obtain.
Embodiment 1,
(1) according to close adjacent principle, selection differentiates object
Selection is suitable to differentiate pair key for liking the Accurate Determining term of validity.After injection steam, oil reservoir near thermal production well shaft bottom
Temperature is significantly raised.With opening well and making production, bottom hole temperature (BHT) and oil production are gradually reduced, to avoid the shadow of producing pressure differential and thickness
Ring, oil production change is general to be characterized using rice productivity index.Therefore, differentiate that object may be selected bottom hole temperature (BHT) and rice productivity index.
When temperature or rice productivity index are reduced to discrimination standard, then it is assumed that thermal recovery is failed.In view of the difference on reservoir characteristics region
It is different, need to select with thermal production well layer that position is identical, position is adjacent cold adopts well object as a comparison, and choosing as far as possible according to phase approximately principle
Select that the production time is more long, production stabilization cold adopt well.If oil field carries out overall Simulation on whole pay zones, well is adopted without cold, then using oil field
With the initial reservoir temperature in layer position as differentiating object before exploitation, or using testing rice productivity index or that Productivity Formulae is calculated is cold
Meter productivity index is adopted as differentiation object.
(2) failure discrimination standard is determined
Failure discrimination standard includes temperature discrimination standard and rice productivity index discrimination standard.When steam-stimulated well bottom hole temperature (BHT)
With rice productivity index be reduced to it is corresponding it is cold adopt well bottom hole temperature (BHT) and rice productivity index when, that is, think thermal production well thermal recovery effect lose
Effect.Well object as a comparison is adopted with adjacent cold in, position identical with the layer position of thermal production well, rice productivity index failure discrimination standard with
The difference of the cold rice productivity index for adopting well is less than 0.05m3/(d·m·MPa)；Opened using thermal recovery in oil field where thermal production well
Hair, is less than before rice productivity index failure discrimination standard and oil field development with the difference of the rice productivity index of the initial oil reservoir in layer position
0.05m3/(d·m·MPa).In view of oil reservoir anisotropism cause after heat injection the regional imbalance of reservoir temperature distribution and
The influence of waste heat, steam soak failure temperature discrimination standard need to it is cold adopt well bottom hole temperature (BHT) on the basis of improve certain amplitude,
Heavy crude reservoir generally for depth more than 1500m selects 2~5 DEG C, and heavy crude reservoir of the depth less than 1500m selects 5~7 DEG C,
And in the bottom hole temperature (BHT) stage of stable development (i.e. the adjacent two monthly average shaft bottom stream temperature approach of thermal production well is less than 1 DEG C).For example for certain steam
Handle up viscous crude field, reservoir buried depth 1300m, cold well bottom hole temperature (BHT) of adopting maintains 48 DEG C or so in process of production, then steam is gulped down
Tell term of validity failure and differentiate that temperature is desirable 53~55 DEG C, any temperature spot between 53~55 DEG C is in the shaft bottom temperature of thermal production well
The stage of stable development (the average bottom hole temperature (BHT) difference of i.e. adjacent two months is less than 1 DEG C) is spent, therefore any temperature spot conduct therein may be selected
The failure of the steam soak term of validity differentiates temperature.For the second round and later round, the temperature discrimination standard of steam soak failure
Need to improve certain amplitude on the basis of shaft bottom stream temperature at the end of last round of time.
(3) thermal production well bottom hole temperature (BHT) and production rate curve are drawn
The bottom hole temperature (BHT) data and rice productivity index data of steam soak after well are taken away, the bottom hole temperature (BHT) of thermal production well is depicted as
The curve changed over time with rice productivity index.
(4) term of validity is determined
Point of the bottom hole temperature (BHT) equal to bottom hole temperature (BHT) failure discrimination standard is found on the curve that bottom hole temperature (BHT) is changed over time,
The point is the first thermal recovery effect failpoint；A meter productivity index is found on the curve that rice productivity index is changed over time to be adopted equal to rice
The point of oil failure discrimination standard, the point is the second thermal recovery effect failpoint；When the first thermal recovery effect failpoint and the second thermal recovery are imitated
Time phase difference corresponding to fruit failpoint takes time and the second thermal recovery corresponding to the first thermal recovery effect failpoint when within 50 days
The intermediate point of time corresponding to effect failpoint is used as the average failpoint of thermal recovery effect；The term of validity is opening well and making production to thermal recovery effect
Time period between average failpoint；When the time phase corresponding to the first thermal recovery effect failpoint and the second thermal recovery effect failpoint
When difference was more than 50 days, the term of validity takes opening well and making production to the time period between the second thermal recovery effect failpoint.
The term of validity to certain steam soak viscous crude field A well is measured in the process of the present invention, determines the bottom hole temperature (BHT) of A wells
With rice productivity index, bottom hole temperature (BHT) and rice productivity index and the change curve between the time are obtained, wherein, thermal production well and cold adopt well
Bottom hole temperature (BHT) and the change curve between the time it is as shown in Figure 1.
The depth of the heavy crude reservoir is 1300m, and it is right as a comparison to adopt well with adjacent cold in, position identical with the layer position of A wells
As the cold well bottom hole temperature (BHT) of adopting maintains 48 DEG C or so in process of production, then in the bottom hole temperature (BHT) stage of stable development (the i.e. phase of thermal production well
The average bottom hole temperature (BHT) difference of adjacent two months is less than 1 DEG C) the steam soak term of validity temperature discrimination standard of selection A wells, it is taken as 54 DEG C.
Well object as a comparison is adopted with adjacent cold in, position identical with the layer position of thermal production well, rice productivity index fail discrimination standard with it is cold
The difference for adopting well rice productivity index is 0.03m3/(d·m·MPa)。
Steam soak term of validity temperature discrimination standard obtained above is substituting to the change between bottom hole temperature (BHT) and time
In curve, time point is obtained for the first thermal recovery effect failpoint, be 310 days；Productivity index obtained above failure is differentiated into mark
Standard is substituting in the change curve meter between productivity index and time, and the time point for obtaining is the second thermal recovery effect failpoint, is
287 days.Because the first thermal recovery effect failpoint is differed within 50 days (23 days) with the second thermal recovery effect failpoint, therefore take
The median of one thermal recovery effect failpoint and the second thermal recovery effect failpoint is used as the average failpoint of thermal recovery effect, therefore certain steam
Viscous crude field the first round thermal recovery term of validity of handling up is 299 days.
From the point of view of current thermal recovery oil field development experience, the steam-stimulated well term of validity is generally 180~400 days, if determining knot
Fruit exceedes this scope, then assay method failure of the present invention.
The invention provides a kind of blank for quantitatively determining method, compensate in this respect of steam soak term of validity.
