Description

Technical Field

[0001] The present disclosure relates to the technical field of drilling engineering, and in particular to a budget optimization method and system for development wells. Background Art

[0002] The quality of drilling design is very important for the successful cost budget management of drilling projects, because it contains the two keys to drilling profitable wells, namely: minimizing drilling operation problems and maximizing operation progress. Therefore, a correct and appropriate drilling design will lead to lower-cost drilling. An important step in the design process is the well construction cost budget, which is an indispensable component of economic drilling and the main tool for controlling expenditures. The cost budget ensures that sufficient funds have been approved for drilling without a shortage of funds, or avoids idle funds to achieve the best allocation of financial resources. On the contrary, the cost budget, as the most direct value response data of the drilling design, can directly present the optimization of different parts of the drilling design. By comparing with the cost budget of other wells in the block, it can feedback the parts of the design that need to be optimized.

[0003] One of the major challenges facing drilling operations engineering and management today is preventing cost and schedule overruns. The nature of drilling operations, including the diversity of different tasks involved from well design to completion, the increasing complexity of the technologies used, time pressures, increasingly stringent regulations on safety and environmental requirements, and the huge uncertainty inherent in drilling operations, has led to rising costs and difficulty in setting reasonable financial and time targets.

[0133] Preferably, if any of the material budget comparison results 108 / duration estimate comparison results 109 indicates an over-limit, the computing device 101 can conduct an expert review on the over-limit material budget comparison result 108 / duration estimate comparison result 109, and if the expert review is passed, update the corresponding material budget distribution 106 / duration estimate distribution 107 based on the material budget 104 / duration estimate 105 corresponding to the over-limit material budget comparison result 108 / duration estimate comparison result 109.

[0136] Embodiment 2:

[0137] Continue to refer Figure 2 , shows a process 200 of the second embodiment of the budget optimization method for developing wells according to the present disclosure. The method can be Figure 1 The method for optimizing the budget of a development well comprises the following steps:

[0138] Step 201, obtain the well section budget information of the target development well at different opening times, and filter out multiple material budgets and multiple time estimates corresponding to each opening time based on preset screening indicators.

[0139] In some embodiments, the execution entity of the budget optimization method for developing wells (such as Figure 1 The computing device 101 shown can be connected to the target device through a wired connection or a wireless connection, and then the well section budget information of the target development well at different openings is obtained, and the various material budgets and various time estimates corresponding to each opening are screened out based on the preset screening indicators. Development wells can refer to drilling in the development stage. Development wells have different opening stages during the drilling process. As an example, the first opening can refer to the drilling process of drilling and opening the surface cover before the surface cover is lowered, the second opening can refer to the drilling process of drilling the surface cover cement plug after the surface cover is lowered, and the third opening can refer to the drilling process of drilling the technical casing cement plug after the technical casing is safely lowered into the wellbore at a certain depth in a special formation to stabilize it. Therefore, different openings can refer to any of the above three openings. The budget of the development well includes multiple categories of budgets, such as relocation budget, land leveling budget, land collection budget, drilling budget, logging budget, drilling fluid budget, drill bit budget, casing budget, labor budget, etc. However, some budgets are fixed expenses, and some budgets are variable items. As an example, a fixed budget may include a relocation budget, a land leveling budget, a land expropriation budget, etc.; a variable budget may include a drilling fluid budget, a drill bit budget, a casing budget, etc. The present disclosure mainly regulates and optimizes variable items. A material budget may refer to a budget related to materials, which is correlated with the depth of the development well. A duration estimate may refer to an estimate related to a construction period, which is also correlated with the depth of the development well. A screening index may refer to a pre-set index for screening out the budget categories (types) and construction duration categories that need to be processed from the budget.

[0140] In some optional implementations, the step of determining the screening index includes: obtaining the benchmark budget data and benchmark construction duration of the target development well at each opening, the benchmark budget data includes multiple benchmark fixed budgets and multiple benchmark variable budgets, and the benchmark construction duration includes multiple benchmark construction durations; screening out at least one target benchmark variable budget and target benchmark construction duration in order from large to small, wherein the sum of the at least one target benchmark variable budget accounts for a proportion of the total budget that is not less than a preset first preset value, and the sum of the at least one target benchmark construction duration accounts for a proportion of the total construction duration that is not less than a preset second preset value; determining the screening index according to the at least one target benchmark variable budget and the target benchmark construction duration. The benchmark budget data may refer to relevant data as a standard budget structure for development wells of this type. The benchmark fixed budget may refer to a fixed budget in the benchmark budget. The benchmark variable budget may refer to a variable budget in the benchmark budget. The first preset value may be between 80% and 90%, and may be set as required. Preferably, the first preset value may be set to 80%.

[0141] It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or developed in the future.

[0142] Step 202, compare each material budget / duration estimate with a predetermined corresponding material budget distribution / duration estimate distribution to obtain multiple material budget comparison results / duration estimate comparison results, wherein the material budget distribution represents the corresponding relationship between the depth of development and the budget, and the duration estimate distribution represents the corresponding relationship between the depth of development and the construction duration.

[0143] In some embodiments, the execution subject may compare each material budget with a predetermined corresponding material budget distribution to obtain a plurality of material budget comparison results; and compare each duration estimate with a predetermined corresponding duration estimate distribution to obtain a plurality of duration estimate comparison results. Material budget distribution indicates the corresponding relationship between development depth and budget, that is, different depths correspond to different budgets for each material. Duration estimate distribution indicates that duration estimate distribution indicates the corresponding relationship between development depth and construction duration, that is, different depths correspond to different estimated construction lengths. Material budget distribution / duration estimate distribution may refer to a preset range of relevant budgets / construction durations according to different depths for development wells of similar types to the target development well generated based on historical data. Material budget comparison results / duration estimate comparison results may refer to comparison results related to material budgets and comparison results related to duration estimates obtained based on comparison, respectively. The comparison results may include three states: passing, exceeding upper limit, and exceeding lower limit. Passing means being in the distribution interval, exceeding upper limit means that the budget exceeds the high threshold of the distribution interval, and exceeding lower limit means that the budget is lower than the low threshold of the distribution interval. Exceeding upper limit and exceeding lower limit may be collectively referred to as exceeding limit.

[0144] In some optional implementations, the step of determining the material budget distribution / time estimate distribution includes: obtaining multiple historical well section budget information, and screening out multiple historical material budgets and multiple historical time estimates based on the screening index, each historical material budget / historical time estimate includes multiple historical data; performing probability distribution on each historical material budget / historical time estimate, generating high thresholds and low thresholds corresponding to each historical material budget / historical time estimate at different depths / times based on preset high ratio thresholds and low ratio thresholds, and obtaining the material budget / time estimate distribution. The historical well section budget information may refer to relevant information on the budget data and construction time data of similar type development wells that have been completed and operated normally. Since multiple budget data are obtained, there are multiple discretely distributed data for each depth / time. Perform probability distribution on multiple discretely distributed data, and set high ratio thresholds (e.g., 80%-95%) and low ratio thresholds (e.g., 5%-20%), so as to calculate the corresponding high thresholds and low thresholds. As an example, a certain depth corresponds to 136 data (i.e., 136 historical budget data are obtained), and 20%-80% is set as the ratio threshold (high ratio threshold 80%, low ratio threshold 20%), and 514.3 (low threshold) and 1865.15 (high threshold) can be calculated. Preferably, the high ratio threshold can be 90%, and the low ratio threshold can be 10%.

[0145] It should be noted that each material budget and each duration estimate corresponds to its own budget distribution. As an example, the drilling fluid budget in the material budget needs to be compared with the corresponding drilling fluid budget distribution, the drill bit budget needs to be compared with the corresponding drill bit budget distribution, and the casing budget needs to be compared with the corresponding casing budget distribution. The duration estimate is similar to the material budget, except that the budget corresponding to different depths is converted into the construction duration corresponding to different depths, which will not be repeated here.

[0146] In some optional implementations, in response to a display instruction, the corresponding material budget / duration estimate and the material budget distribution / duration estimate distribution corresponding to the material budget / duration estimate are combined and displayed on the target display interface.

[0147] For the convenience of display, each budget and the corresponding budget distribution can be combined and displayed on the corresponding display interface. Figure 6 As shown in the figure, a schematic diagram of casing budget and casing budget distribution is shown. The casing budget distribution can refer to the interval formed between the high threshold and the low threshold in the figure. The duration estimation is similar to it, and the horizontal axis can be changed to the construction duration, and no more examples are given.

[0148] Step 203, if any of the material budget comparison results / duration estimate comparison results indicates an over-limit, an expert review is conducted on the material budget comparison result / duration estimate comparison result that exceeds the limit, and if the expert review is passed, the corresponding material budget distribution / duration estimate distribution is updated based on the material budget / duration estimate corresponding to the material budget comparison result / duration estimate comparison result that exceeds the limit.

[0149] In some embodiments, the above-mentioned executive entity may process different material budget comparison results / duration estimate comparison results separately. If the above-mentioned budget comparison result indicates a pass, the budget comparison result may be sent to a processing module corresponding to the pass. If the above-mentioned budget comparison result indicates an over-limit (exceeding the upper limit or exceeding the lower limit), the above-mentioned executive entity may subject the over-limit material budget comparison result / duration estimate comparison result to an expert review. If the expert review fails, the application will be rejected. If the expert review passes, it means that there are parts of the budget that can be improved. Therefore, the corresponding material budget distribution / duration estimate distribution may be updated based on the material budget / duration estimate corresponding to the over-limit material budget comparison result / duration estimate comparison result. For the specific separate processing of exceeding the upper limit and exceeding the lower limit, the following steps may be referred to for processing:

[0150] If any of the material budget comparison results / time estimate comparison results indicates that the lower threshold is exceeded, the corresponding material budget / time estimate will be sent to the preset excess reduction processing port for corresponding expert review. Exceeding the lower limit indicates that the budget has been structurally improved, and the structural improvement can greatly reduce costs. Therefore, after such results are reviewed and approved by experts, the experience can be shared with other development wells, and the budget distribution of the development wells can be updated.

[0151] If any of the material budget comparison results / duration estimate comparison results indicates that it exceeds the high threshold, determine whether the structure of the well section budget information is the same as the existing structure; if different, determine whether the well section budget information is reduced, if reduced, it means passed; if not reduced, send the corresponding material budget / duration estimate to the preset excess budget processing port for corresponding expert review. Since each material budget / duration estimate must be compared separately, if one budget exceeds the standard, but the overall budget is reduced, and the budget structure is different from the existing structure, it can be said that the structure of the budget is designed to be better, and the budget distribution of the development well can be updated based on this.

[0152] In addition, the budget distribution of development wells can be updated at preset intervals.

[0153] In some optional implementations, historical budget data of the type corresponding to the target development well in the previous period is obtained at every preset period, and the material distribution interval and time distribution interval are updated according to the historical data. The preset period may be 3 months, 6 months or 12 months, etc. Since the development cycle of the development well is relatively long, the update period matches the development cycle, and the update frequency is generally more than 3 months, which is set as needed and is not specifically limited here.

[0154] Obtain the budget information of the target development well at each different opening, and select multiple material budgets and multiple time estimates corresponding to each opening based on preset screening indicators; compare each material budget / time estimate with the corresponding predetermined material budget distribution / time estimate distribution to obtain multiple material budget comparison results / time estimate comparison results; if any of the material budget comparison results / time estimate comparison results indicates an over-limit, conduct an expert review, and if the expert review is passed, update the corresponding material budget distribution / time estimate distribution, so that reasonable financial and time goals can be set, greatly enhancing the accuracy of the budget.
