[0047] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0048] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0049] refer to Figure 1 The present invention proposes a comprehensive evaluation method for exploration effectiveness, comprising:

[0050] S1, obtain planned exploration data and actual exploration data for multiple periods (e.g., the past five years) (in addition, mineral rights data of the study area can also be obtained, including prospecting rights and mining rights data);

[0051] S2, based on the planned exploration data and the actual exploration data of the multiple periods, determining multiple initial values ​​of multiple evaluation indicators in the multiple periods; wherein the multiple evaluation indicators include: well completion progress, footage completion progress, proportion of proven reserves within the prospecting right, new EV geological reserve discovery cost, exploration well success rate, reserve discovery cost, drilling efficiency, meter footage increase, single well increase, and well site preparation rate;

[0052] S3, calculating multiple normalized values ​​of the multiple evaluation indicators in the multiple periods based on multiple initial values ​​of the multiple evaluation indicators in the multiple periods and a normalization formula;

[0053] S4, calculating comprehensive evaluation parameters of exploration effectiveness in each of the multiple periods based on the multiple normalized values ​​of the multiple evaluation indicators in the multiple periods.

[0054] In an embodiment of the present invention, a comprehensive evaluation is performed based on ten evaluation indicators, including the completion progress of the number of wells, the completion progress of footage, the proportion of proven reserves within the prospecting right, the cost of discovering new EV geological reserves, the success rate of exploration wells, the cost of discovering reserves, drilling efficiency, increased reserves per meter footage, increased reserves per well, and well site preparation rate. After normalization and calculation, the comprehensive evaluation parameters of exploration effectiveness are finally obtained. This allows for a more comprehensive and reasonable evaluation of previous exploration results from more angles, which is conducive to effective guidance of subsequent exploration plans. In particular, the multiple evaluation indicators of the present invention include indicators that are not used in the prior art, such as "the proportion of proven reserves within the prospecting right", "the cost of discovering new EV geological reserves", and "well site preparation rate". The inventors of this application realize that these indicators have good reference value when evaluating exploration effectiveness, and thus incorporate them into the evaluation indicator set of the present invention.

[0055] In some embodiments, the planned exploration data for the multiple periods include the following data for each period: the planned number of exploratory wells and the planned footage; the actual exploration data for the multiple periods include the following data for each period: the actual number of exploratory wells, the actual footage, the success rate of exploratory wells, the newly added proven reserves, the newly added controlled reserves, the newly added predicted reserves, the drilling and completion time of all newly added exploratory wells, and the number of exploratory well reserves (the number of exploratory wells designed but not implemented at the beginning of the year).

[0056] Among the multiple evaluation indicators of the present invention, the following indicators can be directly obtained from previous actual exploration data: the proportion of proven reserves within the prospecting right (in the embodiment of the present invention, the proportion of proven reserves within the prospecting right = proven reserves within the prospecting right / total proven reserves), the cost of discovering new EV geological reserves (in the embodiment of the present invention, the cost of discovering new EV geological reserves = exploration investment / EV geological reserves), the success rate of exploration wells, the cost of discovering reserves, and the drilling efficiency (characterized based on drilling time, which can be directly obtained). Other indicators are calculated based on actual exploration data and planned exploration data, and the calculation method is as follows:

[0057] Calculate the ratio of the actual number of exploration wells to the planned number of exploration wells in a certain period as the initial value of the well completion progress in this period;

[0058] Calculate the ratio of the actual footage to the planned footage in a certain period as the initial value of the footage completion progress in this period;

[0059] Calculate the ratio of the number of exploration well reserves to the number of planned exploration wells in a certain period as the well site readiness rate for this period;

[0060] Calculate the ratio of newly added EV geological reserves to actual footage in a certain period as the initial value of the increased reserves per meter footage in this period;

[0061] Calculate the ratio of newly added EV geological reserves to the actual number of exploration wells in a certain period as the initial value of single well reserve increase in this period;

[0062] Among them, the newly added EV geological reserves = newly added proven reserves + 2 / 3 newly added controlled reserves + 1 / 3 newly added predicted reserves.

[0063] In some embodiments, for the following evaluation indicators (the initial values ​​of these evaluation indicators are positively correlated with the exploration results): well completion progress, footage completion progress, proportion of proven reserves within the prospecting right, new EV geological reserve discovery cost, exploration well success rate, meter footage increase in reserves, single well increase in reserves, well site preparation rate, the normalized formula is:

[0064]

[0065] For the following evaluation indicators (the initial value of the evaluation indicator has a negative correlation with the exploration results): reserve discovery cost, drilling efficiency, the normalized formula is:

[0066]

[0067] Among them, A1 is the normalized value of a certain evaluation index in a certain period; A0 is the initial value of this evaluation index in this period; A0max is the maximum initial value of this evaluation index in the multiple periods; A0min is the minimum initial value of this evaluation index in the multiple periods; the drilling time is taken as the initial value of the drilling efficiency, that is, when A1 is the normalized value of the drilling efficiency in a certain period, A0 is the drilling time of this period; A0max is the maximum value of the drilling time in the multiple periods; A0min is the minimum value of the drilling time in the multiple periods.

[0068] Through the above normalization formula, the evaluation indicators of a single period can be compared longitudinally with those of multiple periods, and the initial value of each evaluation indicator can be mapped to between 0 and 100 (equivalent to assigning points between 0 and 100), and regardless of whether there is a positive or negative correlation between its initial value and the exploration results, after the evaluation indicator is normalized, there is a positive correlation between the normalized value and the exploration results, that is, the higher the normalized value, the better the exploration results.
