[0002] Marine seismic exploration is characterized by high investment, high risk, and high requirements. In a complete marine seismic exploration and acquisition project, the construction period is an important factor in the project's operating cost accounting.

[0003] Currently, marine seismic exploration and acquisition projects can be categorized into several types, including streamer seismic exploration, on-board cable seismic exploration (OBC), and on-board nodal seismic exploration (OBN). OBC and OBN acquire seismic data by placing receiving equipment (cables or marine nodals) on the seabed; while streamer acquisition uses a ship to tow a cable to the sea surface for excitation and reception. Because the construction methods differ for different types of seismic exploration projects, the required types and numbers of construction vessels, as well as the number of seismic sources needed for excitation, also vary. Therefore, there is a lack of methods in the relevant technologies for accurately calculating the construction cycle of marine seismic exploration and acquisition projects.

[0004] Therefore, how to accurately and conveniently determine the construction period of marine seismic exploration and acquisition projects, so as to provide important technical reference for the operation of marine seismic exploration and acquisition business, is an urgent technical problem to be solved.

Obviously, the accompanying drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0033] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other words can achieve the same purpose, they may be replaced by other expressions.

Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0035] Flowcharts are used in this application to illustrate the operations performed by the system according to embodiments of this application. It should be understood that the preceding or following operations are not necessarily performed precisely in sequence. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0036] For ease of understanding, the technical solution of this application is described below with reference to the accompanying drawings and embodiments.

[0037] Figure 1 This is an exemplary flowchart illustrating a method for determining the construction period of a marine seismic exploration and acquisition project according to some embodiments of this application.

[0038] Step S110: Obtain the pre-relocation duration, relocation duration, and dismissal duration of the marine seismic exploration and acquisition project.

[0039] In practice, the construction process of marine seismic exploration and acquisition projects can be uniformly divided into four stages: pre-relocation phase, relocation phase, operational phase, and dispersal phase. Therefore, the construction cycle (i.e., the total project duration) of a marine seismic exploration and acquisition project includes: the pre-relocation phase duration, the relocation phase duration, the operational phase duration, and the dispersal phase duration.

[0040] Because the duration of the pre-relocation, relocation, and evacuation phases for each marine seismic exploration and acquisition project is generally not fixed, therefore, such as Figure 4 As shown, based on the operational status of the marine seismic exploration and acquisition project, a fixed duration can be set for each of the following: pre-relocation duration, relocation duration, and evacuation duration: Pre-relocation duration - (hours); Relocation duration - (hours); severance period - (Hour).

[0041] Homework duration - (hours), which is related to the acquisition parameters of marine seismic exploration and acquisition projects, can be calculated through the following steps.

[0042] Step S120: Determine the operation duration of the marine seismic exploration and acquisition project based on the acquisition parameters of the marine seismic exploration and acquisition project.

[0043] The acquisition parameters include at least the length of the source vessel used in the marine seismic exploration acquisition project, the number of routes, and the speed of the vessel.

[0044] In the specific implementation process, such as Figure 5 As shown, the operation time of a marine seismic exploration and acquisition project can be divided into two parts: production time and non-production time. The operation time of a marine seismic exploration and acquisition project can be determined in various ways based on the acquisition parameters of the project.

[0045] For an example of determining the operation duration of a marine seismic exploration and acquisition project based on its acquisition parameters, see [link to example]. Figure 2 The relevant content will not be repeated here.

[0046] Step S130: Determine the construction period of the marine seismic exploration and acquisition project based on the pre-relocation period, relocation period, dismissal period, and operation period.

[0047] In the specific implementation process, the construction cycle of the marine seismic exploration and acquisition project can be obtained by calculating the sum of the pre-relocation period, relocation period, dismissal period, and operation period. The calculation formula is as follows:

[0048] (1)

[0049] In the embodiments provided in this application, the construction process of a marine seismic exploration and acquisition project is uniformly divided into four stages: pre-relocation phase, relocation phase, operation phase, and dispersal phase. The operation duration of the marine seismic exploration and acquisition project is determined based on the acquisition parameters. The construction cycle of the marine seismic exploration and acquisition project is determined based on the duration of the pre-relocation phase, relocation phase, dispersal phase, and operation phase. This allows for accurate and convenient determination of the construction cycle of the marine seismic exploration and acquisition project.

[0050] Figure 2 This is an exemplary flowchart illustrating a method for determining the operation duration of a marine seismic exploration and acquisition project according to some embodiments of this application.

[0051] Step S210: Determine the production time of the single-source vessel based on the acquisition parameters of the marine seismic exploration and acquisition project.

[0052] In the specific implementation process, such as Figure 5 As shown, the production time of a single-source seismic vessel can be divided into main line production time and supplementary line production time. The production time of a single-source seismic vessel can be determined in various ways based on the acquisition parameters of the marine seismic exploration and acquisition project.

[0053] For a specific implementation example of determining the production time of a single-source vessel based on the acquisition parameters of a marine seismic exploration and acquisition project, please refer to [link to relevant documentation]. Figure 3 The relevant content will not be repeated here.

[0054] Step S220: Obtain the proportion of each item in the non-production time of a single-source seismic vessel to the total operating time.

[0055] In some embodiments, the proportion of each item and operation time included in non-production time can be determined based on past project experience or budget.

[0056] For example only, such as Figure 5 As shown, non-production time T NP (hours) are determined by paid waiting time ( T CS ), Shift work hours ( T CC ), supply duration ( T Re ), downtime due to malfunction ( T TD Unpaid waiting time ( T NCS ), duration of dispute ( T D It consists of 6 parts, each accounting for a percentage of the single-source vessel's operating time: paid waiting time percentage - P CS Shift work hours ratio P CC Supply duration ratio - P Re , Percentage of downtime due to malfunction - P TD Percentage of unpaid waiting time - P NCS Dispute duration ratio - P D The formula for calculating the non-productive time of a single-source seismic vessel is as follows:

[0057] (2)

[0058] in, This refers to the operating time of a single-source seismic vessel.

[0059] Among them, paid waiting time ( TCS )for:

[0060] (3)

[0061] Among them, the number of shifts ( T CC )for:

[0062] (4)

[0063] Among them, the supply duration ( T RE )for:

[0064] (5)

[0065] Among them, downtime ( T TD )for:

[0066] (6)

[0067] Among them, unpaid waiting time ( T NCS )for:

[0068] (7)

[0069] Among them, the duration of the dispute ( T D )for:

[0070] (8)

[0071] Step S230: Determine the operating time of the single-source seismic vessel based on the production time of the single-source vessel and the proportion of each item included in the non-production time to the operating time.

[0072] In some embodiments, the formula for calculating the operation time of a single-source vessel is as follows:

[0073] (9)

[0074] in, For the proportion of paid waiting time, For the proportion of staff shift work hours, For the proportion of resupply time, For the proportion of downtime due to faults, For the proportion of unpaid waiting time, For the proportion of disputed time, The production time for a single-source seismic vessel.

[0075] Step S240: Based on the operating time of the single-source vessel, obtain the operating time of the marine seismic exploration and acquisition project.

[0076] In practice, marine seismic exploration and acquisition projects involve at least one single-source vessel, and the operation time of such projects can be obtained through the following methods:

[0077] Determine the joint construction coefficient of multi-source vessels I Based on the operating time of a single-source seismic vessel Combined construction coefficient with multi-source seismic vessels I The ratio between these two values ​​yields the operation time of a marine seismic exploration and acquisition project. The calculation formula is as follows:

[0078] (10)

[0079] Among them, the joint construction coefficient of multi-source vessels during single-source vessel construction is... I The value is 1.

[0080] Figure 3 This is an exemplary flowchart illustrating a method for determining the production time of a single-source ship according to some embodiments of this application.

[0081] Step S310: Determine the mainline production acquisition time and the mainline production line changeover time for the single-source seismic vessel.

[0082] In the specific implementation process, such as Figure 5 As shown, the mainline duration can be further divided into mainline production acquisition duration and mainline production line changeover duration.

[0083] In some embodiments, the mainline production acquisition time for a single-source seismic vessel can be determined using the following formula:

[0084] (11)

[0085] in, The main production collection time L Given the average length of the route, N For the number of routes, V This refers to the average production speed.

[0086] In some embodiments, the mainline production changeover time for a single-source vessel can be determined using the following formula:

[0087] (12)

[0088] in, The main production changeover time is A, where A is the average changeover time and N is the number of production lines.

[0089] Step S320: Determine the mainline production time of the single-source vessel based on the mainline production acquisition time and the mainline production line changeover time.

[0090] In the specific implementation process, the sum of the mainline production acquisition time and the mainline production line change time of a single-source seismic vessel can be calculated and used as the mainline production time of the single-source seismic vessel.

[0091] Step S330: Determine the production time for the supplementary line of a single-source seismic vessel based on the product of the main production time and the average supplementary line ratio.

[0092] In the specific implementation process, such as Figure 5 As shown, the production time for supplementary seismic lines is the same as that for the main seismic line, and both can be subdivided into production acquisition time and production line changeover time. The production time for supplementary seismic lines on a single-source seismic vessel can be calculated using the following formula:

[0093] (13)

[0094] (14)

[0095] in, The average line-filling ratio, To supplement production line data collection time, To reduce the time required for production line replacement, The main production collection time This refers to the changeover time for the main production line.

[0096] Step S340: Determine the production time of the single-source vessel based on the main production time and the supplementary production time.

[0097] In practical implementation, the production time of a single-source seismic vessel can be calculated by summing the mainline production time and the auxiliary production time. The calculation formula is as follows:

[0098]

[0099] (15)

[0100] As an example only, the following describes the specific implementation process of the method provided in this application using a 3D OBN project as an example:

[0101] Given that the average production speed of the source ship for this project is 5.20 knots, the average length of the source ship route is 19.0 kilometers, the number of routes is 506, and the average route change time is 0.3 hours, the main line production collection time can be obtained from formula (11) as 998.31 hours.

[0102] The average line changeover time for the project is 0.3 hours. According to formula (12), the main line changeover time is 151.80 hours.

[0103] Given that the average replenishment ratio of the project is 1.89%, according to formulas (13) and (14), the replenishment production collection time is 18.87 hours and the replenishment production line changeover time is 2.87 hours, respectively.

[0104] The production time of a single-source ship can be obtained from formula (15) as 1171.84 hours.

[0105] Given that the paid waiting time accounts for 6.59% of the total operating time of a single-source vessel, the shift work time accounts for 1.15% of the total operating time of a single-source vessel, the resupply time accounts for 1.73% of the total operating time of a single-source vessel, the breakdown waiting time accounts for 1.35% of the total operating time of a single-source vessel, the unpaid waiting time accounts for 10.43% of the total operating time of a single-source vessel, and the dispute time accounts for 0% of the total operating time of a single-source vessel, the total operating time of a single-source vessel is 1488.05 hours according to formula (9).

[0106] According to formulas (3) to (8), the paid waiting time is 98.06 hours, the staff shift time is 17.11 hours, the replenishment time is 25.74 hours, the downtime is 20.09 hours, the unpaid waiting time is 155.20 hours, and the dispute time is 0 hours.

[0107] Since this project involves single-source vessel operations, the joint construction coefficient for multi-source vessels is 1. According to formula (10), the total operation time of the project is 1488.05 hours.

[0108] Finally, according to formula (1), the project's pre-relocation time (168.00 hours), relocation time (72.00 hours), operation time (1488.05 hours), and dismissal time (108.00 hours) are summed to obtain the total project time of 1836.05 hours, which is consistent with the actual production time of the project.

[0112] The second acquisition module 620 is used to determine the operation time of the marine seismic exploration and acquisition project based on the acquisition parameters of the marine seismic exploration and acquisition project; wherein, the acquisition parameters include at least: the route length, number of routes, and sailing speed of the source vessel used in the marine seismic exploration and acquisition project.
