The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention.
Aiming at the problem that the oil field yield increase data cannot be quantitatively and efficiently analyzed in the prior art, the embodiment of the invention provides an oil field yield increase data analysis method and device, which aim to accurately and efficiently analyze the oil field yield increase data through ton oil profit data.
FIG. 1 is a schematic diagram of a method for analyzing field stimulation data according to an embodiment of the present invention, as shown in FIG. 1, the method may include:
step 101, obtaining yield increase data of the oil field in different yield increase modes, wherein the different yield increase modes comprise: new well digging and old well adding measures, wherein the old well measures comprise one or more measures;
102, determining the oil per ton profit data of the new well in the evaluation period and the oil per ton profit data of the new well in the future according to the yield increase data;

and 105, comparing and analyzing the oil return data of the new well in the effective period with the oil return data of the old well in the evaluation period.
As can be seen from fig. 1, in the embodiment of the present invention, by obtaining the yield data of the oil field in different yield increasing modes, calculating the valid period ton oil profit data of the new well and the evaluation period ton oil profit data of each old well measure according to the yield data, and comparing and analyzing the valid period ton oil profit data of the new well and the evaluation period ton oil profit data of each old well measure, a method for accurately and efficiently analyzing the yield data of the oil field is realized.
In specific implementation, yield increasing data of the oil field under different yield increasing modes are obtained firstly, wherein the different yield increasing modes comprise: new well making and old well adding measures, wherein the old well measures comprise one or more measures. For example, old well actions include hole making, fracturing, sand control, pump down, pump up, pump down, acidizing, deep pumping, chemical water shutoff, overhaul, and the like. The old well action described in this embodiment may include one or more of the above examples.
In order to analyze and compare the oil field yield increase data of the new well and the old well, an evaluation period is set, wherein the evaluation period is the same time for the new well and the old well, for example, the evaluation period is from 2019 to 2028, and the oil field yield increase data of the new well and the old well are analyzed and compared in the evaluation period.
The new well validity period is known to represent the time difference from the production time of a new well to the occurrence of a negative value of profit, and is different from the old well measure validity period, the new well is made longer, the old well measure validity period is increased shorter, and the new well validity period also includes the future year, that is, after one evaluation period is set, the new well validity period includes the new well evaluation period and the new well future year, and the old well measure validity period includes only the old well evaluation period. For example, the evaluation period is from 2019 to 2028, and then the new well evaluation period and the old well evaluation period are from 2019 to 2028. If the new well has not been in year 2028 to 2033, then the new well expiration date is from 2019 to 2033 and the old well expiration date is from 2019 to 2028.
In the specific implementation, the ton oil profit data in the evaluation period of the new well and the ton oil profit data in the future year are determined according to the yield increase data. In one embodiment, the stimulation data may include: the evaluation period is the annual duration, the oil price in the new well evaluation period, the unit complete cost in the new well evaluation period and the oil yield in the new well evaluation period. The yield increase data can be directly obtained through corresponding known data, waiting for a period of time is not needed, and efficiency is improved.
Specifically, the new well evaluation period oil price can be obtained by taking the current annual oil price as a base. The oil price in the new well evaluation period can be the oil price of each ton of oil, namely the oil price in the new well evaluation period can be obtained by taking the oil price in the current year as a base number.
The new well evaluation period unit total cost may be a unit total cost without depreciation. For example, obtaining a new well evaluation period unit completion cost may include: obtaining new year period fees, new year tax, new year exploration fees and new year operation costs; obtaining the new year unit complete cost according to the new year period fee, the new year tax, the new year exploration fee and the new year operation cost; obtaining the unit complete cost of the new well year, namely obtaining the unit complete cost of the corresponding year of the new well evaluation period. Wherein the new year period fee, the new year tax fee, and the new year exploration fee are obtained, for example, by the current annual oil price; the new well year operating cost can be predicted and obtained according to the change rule of the operating cost in the known year.
In practice, the unit total cost of the new well evaluation period is not limited to the year, but may be a unit total cost of the new well evaluation period or a unit total cost of the new well evaluation period and month. Accordingly, the new well evaluation period oil production may be new well evaluation period annual oil production, new well evaluation period quarter oil production, or new well evaluation period monthly oil production.
In the above embodiment, the new well year unit full cost is obtained, e.g., the new well is charged R during the ith year Period i Representing new well i year tax by R Tax i Representing the ith exploration cost of a new well as R Exploration i Representing the ith year operation cost of a new well as R Operation i Meaning that the new well is at annual unit full cost (no depreciation) R i The method comprises the following steps: r is R i ＝R Period i +R Tax i +R Exploration i +R Operation i . Correspondingly, the unit complete cost (without depreciation) R of the ith year of the new well is obtained i I.e. obtaining the unit complete cost R of the ith year of the new well evaluation period i New well evaluation ＝R i 。
The oil production during the evaluation period of the new well can be obtained by the decreasing law of the crude oil production in known years.
The evaluation period year duration may be, for example, a 5 year, 10 year, or other set year duration. In practice, the evaluation period and the month duration can be replaced by the evaluation period and the month duration.
In specific implementation, the oil per ton profit data of the new well in the evaluation period is determined according to the yield increase data, for example, the total accumulated profit of the new well in the evaluation period and the accumulated oil yield of the new well in the evaluation period can be calculated according to the yield increase data, and then the oil per ton profit data of the new well in the evaluation period, which is the ratio of the total accumulated profit of the new well in the evaluation period and the accumulated oil yield of the new well in the evaluation period, is calculated.
In the above embodiment, for example, M New well evaluation (i) Indicating the oil price of the new well in the ith year of evaluation period, R i New well evaluation Representing the unit complete cost of the ith year of the new well evaluation period, and m represents the annual duration of the evaluation period, then the new well evaluation period accumulates total profit P Evaluation of Total profit Can be calculated as follows:
for example, by Q i New well evaluation Indicating the oil production of the ith year of the new well evaluation period, and indicating the annual duration of the evaluation period by m, the accumulated oil production Q of the new well evaluation period Evaluation of total oil production I.e., the cumulative oil production for the new well evaluation period m years can be calculated according to the following formula:
from the calculated ratio of the total accumulated profit of the new well evaluation period and the accumulated oil production of the new well evaluation period, i.e. the oil per ton profit data of the new well evaluation period, the oil per ton profit data P of the new well evaluation period Evaluation period The method can be calculated according to the following formula:
in particular, determining future annual ton oil profit data for a new well from the stimulation data may include, in one embodiment: the evaluation period is the time of year, the oil price of the new well in the future, the unit complete cost of the new well in the future, the oil production of the new well in the future, and the time of year of validity of the new well.
Specifically, the new well oil price, the new well unit complete cost and the new well oil production are respectively similar to the new well evaluation period oil price, the new well evaluation period unit complete cost and the new well evaluation period oil production, and the methods for obtaining the new well oil price, the new well unit complete cost and the new well evaluation period oil production are also applicable to the methods of the previous embodiments.
Wherein the new well expiration date year duration represents the length of time of the new well expiration date. For example, the new well expiration date is typically expressed in terms of a year duration, that is, the new well expiration date may be expressed by a new well expiration date year duration. The validity period of the new well can be shown according to the productivity construction prediction result, the average of the new well thin oil block is 15 years, the high-freezing oil block is 12 years, the thick oil block is 10 years, and the super thick oil block is 15 years.
In the present embodiment, for example, M Future of new well (i) Indicating that the new well is notThe oil price in the year i is R i New well future Representing the unit complete cost of the new well in the i-th year of the future year, m represents the evaluation period year duration, n represents the new well validity period year duration, and then the total profit P is accumulated in the future year of the new well Future total profit The method can be calculated according to the following formula:
for example, by Q i New well future Indicating the oil production of the new well in the i-th year of the future year, m indicating the evaluation period year duration, n indicating the new well validity period year duration, and then accumulating the oil production Q of the new well in the future year Future total oil production The method can be calculated according to the following formula:
similar to the evaluation period ton oil profit data calculation of the new well, future year ton oil profit data P of the new well Years of coming The method can be calculated according to the following formula:
in particular, in one embodiment, determining the expiration date per ton oil profit data for the new well based on the evaluation period per ton oil profit data and the future year per ton oil profit data for the new well includes: and determining the oil return data of the new well in ton according to the following formula:
P new well ＝P Evaluation period +P Years of coming
Wherein P is New well Ton oil profit data representing the expiration date of a new well; p (P) Evaluation period Ton oil profit data representing the evaluation period of the new well; p (P) Years of coming Future annual ton oil profit data representing new wells.
The evaluation period ton oil profit data P of the new well can be obtained Evaluation period And future years of new wellsPer ton oil profit margin data P Years of coming Substituting the data into the above formula to obtain the oil profit data of the new well in ton.
In particular implementations, the evaluation period ton oil profit data for each old well measure is determined based on the stimulation data, which in one embodiment may include: the evaluation period is long in year, commodity rate, oil increment of the old well measure evaluation period, oil price of the old well measure evaluation period, unit complete cost of the old well measure evaluation period, effective well times of the old well measure and single well time cost of the old well measure.
The commodity rate may be, for example, a crude commodity rate.
The oil increasing amount of the old well measure evaluation period measure can be obtained through the oil increasing amount prediction of the old well measure.
The oil price in the old well measure evaluation period and the unit complete cost in the old well measure evaluation period are similar to the methods for obtaining the oil price in the new well evaluation period and the unit complete cost in the new well evaluation period.
Old well measure effective well times refer to, for example, oil wells: the daily oil yield of the well is more than 10 tons, and the oil yield is increased by more than 20 percent after construction; the daily oil yield is greater than 100 tons and less than 10 tons, and the oil yield is increased by more than 10 percent after construction.
The single well cost of old well measures mainly comprises material cost and construction labor cost.
Determining estimated period ton oil profit data for each old well measure according to the stimulation data, comprising:
and determining the oil profit data of each old well measure in the evaluation period according to the following formula:
wherein P is Old well measure j Ton oil profit data representing the evaluation period of the jth old well measure; q (Q) ij evaluation Indicating the j-th old well measureThe oil increasing amount is measured in the ith evaluation period; m is M Old well evaluation (i) Indicating the oil price of the ith year of the old well measure evaluation period; r is R i evaluation of old well Representing the unit complete cost of the ith year of the old well measure evaluation period; f represents commodity rate; a, a ij Representing the effective well number of the jth old well measure in the ith year; c ij Single well cost representing the jth old well measure in the ith year; m represents the annual length of the evaluation period;and the accumulated oil increasing amount of the j-th old well measure evaluation period m years is shown.
In the concrete implementation, the oil return data of the new well in the effective period and the oil return data of the old well in the evaluation period are respectively compared and analyzed. In one embodiment, the method comprises the steps of: the economic evaluation coefficient of the yield increasing effect is calculated according to the following formula:
n＝P new well /P Old well measure j
Wherein n represents an economic evaluation coefficient of the yield-increasing effect; p (P) New well Ton oil profit data representing the expiration date of a new well; p (P) Old well measure j Ton oil profit data representing the evaluation period of the jth old well measure;
and determining an optimal yield increasing mode from the different yield increasing modes according to the economic evaluation coefficient of the yield increasing effect.
For example, when comparing stimulation data for a new well and an old well addition, a stimulation effect economic evaluation coefficient n is obtained, indicating that the new well is created equivalent to the addition of n old well addition. For example, when n is greater than 1, this indicates that the stimulation effect of the new well is better than the stimulation effect of the old well. When n is less than 1, the yield increasing effect of the old well increasing measure is better than that of the new well.
Therefore, after the economic evaluation coefficient of the yield increasing effect is obtained, the oil field yield increasing data can be quantitatively and accurately analyzed.
