[0056] Example 1

[0057] like Figure 1 As shown, this embodiment provides a method for calculating the economic workload of block exploration, which includes step S1, step S2, step S3 and step S4.

[0058] Step S1, obtaining exploration data of the block to be predicted in a historical period, wherein the exploration data includes annual newly added proved reserves, annual newly added proved reserves of a single well, and annual drilling number;

[0059] In this step, the historical time period can be customized by the user. In this embodiment, the historical time period is 2006-2013. The exploration data of the block to be predicted in the historical time period is shown in Table 1, where the annual newly added proved reserves of a single well is the ratio between the annual newly added proved reserves and the annual number of wells drilled;

[0060] Table 1

[0061] year Annual newly discovered reserves Annual newly discovered reserves of a single well Annual drilling number 2006 10255 100 103 2007 10649 92 116 2008 10281 84 122 2009 9387 80 117 2010 8213 78 105 2011 6956 74 94 2012 5746 72 80 2013 4657 70 67

[0062] Step S2, calculating the annual newly added proved reserves of the single well corresponding to each future year and the deadline for stopping exploration of the block to be predicted based on the annual newly added proved reserves of the single well;

[0063] The specific implementation steps of this step include step S21 and step S22;

[0064] Step S21, set formula (1), the formula (1) is:

[0065] y t =ae bt (1)

[0066] In formula (1), y refers to the annual newly discovered reserves of a single well, t refers to the serial number corresponding to each year, a is the first coefficient, and b is the second coefficient;

[0067] In this step, t can be understood as t=1, 2, 3, 4, 5, 6, 7...n

[0068] Step S22, according to the annual newly increased proved reserves of the single well and the formula (1), calculate the values ​​of the first coefficient and the second coefficient, and predict the annual newly increased proved reserves of the single well corresponding to each future year according to the values ​​of the first coefficient and the second coefficient; and calculate the deadline for stopping exploration of the block to be predicted according to the annual newly increased proved reserves of the single well corresponding to each future year.

[0069] In this step, the exponential fitting method can be used to obtain the first coefficient and the second coefficient using Excel software, which are 121.41 and -0.088 respectively. Therefore, formula (1) is y t =121.41e (-0.088t) ;

[0070] According to the calculated formula (1), the annual newly added proved reserves of a single well corresponding to each future year can be calculated. In this step, the annual newly added proved reserves of a single well corresponding to the future years 2014-2027 are predicted using formula (1), as shown in Table 2.

[0071] At the same time, in this step, the deadline for stopping exploration of the block to be predicted is calculated according to the annual newly added proven reserves of the single well corresponding to each future year, which is specifically carried out through the following steps:

[0072] The annual newly added proved reserves of a single well corresponding to each future year are analyzed. When the annual newly added proved reserves of a single well corresponding to the future year is less than 150,000 tons / well, this year is used as the deadline for stopping exploration in the block to be predicted; by calculating that the annual newly added proved reserves of a single well after 2027 is less than 150,000 tons / well, it is considered that there is no need for exploration investment. Therefore, 2027 is used as the deadline for stopping exploration in the block to be predicted;

[0073] Step S3, calculating the annual newly added proved reserves corresponding to each future year according to the annual newly added proved reserves;

[0074] The specific implementation steps of this step include step S31 and step S32;

[0075] Step S31, set formula (2), the formula (2) is:

[0076]

[0077] In formula (2), q t is the annual newly discovered reserves, k is the third coefficient, c is the fourth coefficient, and d is the fifth coefficient;

[0078] Step S32: Calculate the values ​​of the third coefficient, the fourth coefficient and the fifth coefficient according to the annual newly added proved reserves and the formula (2); and predict the annual newly added proved reserves corresponding to each future year according to the values ​​of the third coefficient, the fourth coefficient and the fifth coefficient.

[0079] In this step, using Excel software, the values ​​of the third coefficient, the fourth coefficient, and the fifth coefficient in formula (2) are 107112.473, 0.142, and 0.763 respectively, so the formula is The annual additional proved reserves corresponding to each future year are predicted by formula (2), as shown in Table 2;

[0080] Step S4, calculating the exploration economic workload corresponding to the block to be predicted based on the annual newly-proven reserves of the single well corresponding to each future year, the deadline for stopping exploration of the block to be predicted, and the annual newly-proven reserves corresponding to each future year.

[0081] The specific implementation steps of this step include step S41 and step S42;

[0082] Step S41, set formula (3), the formula (3) is:

[0083]

[0084] In formula (3), L is the exploration economic workload corresponding to the block to be predicted, and n is the sequence number corresponding to the cut-off time;

[0085] Step S42, calculating the exploration economic workload corresponding to the block to be predicted based on the formula (3), the annual newly proved reserves of the single well corresponding to each future year, the deadline for stopping exploration of the block to be predicted, and the annual newly proved reserves corresponding to each future year.

[0086] In this step, the exploration workload corresponding to each future year, that is, the number of wells drilled, can be determined by formula (3), as shown in Table 2. Then, the exploration workload corresponding to each future year is added together to obtain the exploration economic workload corresponding to the block to be predicted. Table 2 is as follows:

[0087] year Annual newly discovered reserves Annual newly discovered reserves of a single well Annual drilling number 2014 4196 50 83 2015 2940 46 64 2016 2303 42 55 2017 1793 39 46 2018 1389 35 39 2019 1072 32 33 2020 825 30 28 2021 633 27 23 2022 486 25 19 2023 372 23 16 2024 284 21 14 2025 217 19 11 2026 166 18 9 2027 127 16 8

[0088] Based on the relationship between exploration workload and reserve increase scale, this embodiment can not only determine the years of exploration economic investment, but also predict the time series of block exploration economic workload investment. It is intuitive, easy to use and effective.
