By taking the shale gas drilling engineering in the Changning area as an example, the shale gas drilling engineering intelligent scheduling method provided by the embodiment has better economy, timeliness and accuracy.
(1) Economy of use
Before use: in 2018, the actual average production of a single well is stopped for 7.2 days without technology (the drilling is stopped for 4.4 days, and the fracturing is stopped for 2.8 days), wherein the actual average production is stopped for 5.9 days due to production organization factors and the like. After use: the stopping time is reduced by 70 percent due to production organization factors and the like. Economic benefits are as follows: 3.9 ten thousand yuan for drilling machine ZJ50D and other stopping days, and 13.9 ten thousand yuan for fracturing truck group 2500 type 18 and matched stopping days. The Changning plans to newly open 100 wells in 2020, which can save 3239 ten thousand yuan; the shale gas in south China is planned to be accumulated and newly drilled with 4388 mouths in 2021-2035 years, and 142127 ten thousand yuan can be saved.
By contrast, by improving the professional synergistic ability, the production and other stop time is greatly reduced, and the economic benefit is considerable.
(2) Aging property
Tracking frequency: depending on dynamic data of an industrial monitoring system, the tracking deduction frequency is increased from once a month to once a day; the working efficiency is as follows: the time is shortened from 3 people per day to less than 10min per time; early warning and aging: the time relevance of the early warning information is improved to be within 1 day from 1 to 30 days later.
Through comparison, the dynamic tracking frequency, the working efficiency and the early warning timeliness are greatly improved.
(3) Accuracy of
Before use, the progress tracking is mainly to fill in daily report data through field supervision, and well engineering management posts estimate the completion time of the current working procedure and manually deduce the drilling time of other wells. After the system is used, the progress is filled by field supervision, the completion time is estimated by combining the drilling state, the predicted completion time of a single well is more accurate, and the acquired drilling progress information is put into the system, so that the planned drilling plan is more accurate.

the remaining platforms are "not satisfied.
It should be noted that the platform water demand start time, and the temporary and permanent planned water supply times are recorded by date. As shown in fig. 7-12, three platforms, i.e., an H1 platform, an H2 platform, and an H3 platform, are taken as examples for simplification:

as shown in fig. 9, the platform water demand time of the H3 platform is 20 days (platform water demand start time) 7 and 20 days (platform water demand end time) 2020 and 31 days (platform water demand end time) 10 and 31 days 2020, and the platform daily water demand is 200 square; the daily water supply capacity of the platform for temporary and permanent water supply at the time is always 250, and the daily water demand of the platform can be met, so that the supply and demand balance judgment result of the H1 platform water supply project is 'meeting the demand'.
(3) And (3) judging the supply and demand balance of the power supply project: the supply and demand balance judgment of the power supply project is carried out one by one:
firstly, finding out a platform with the platform power demand starting time being more than or equal to the temporary and planned power supply time of the transformer substation, and if the daily power supply capacity of the temporary and the transformer substation is more than or equal to the daily power supply load of the platform, the platform meets the requirement;
then finding out a platform with the platform power demand starting time more than or equal to the temporary and planned power supply time of the transformer substation, wherein the daily power supply capacity of the temporary and transformer substations is less than the daily power supply load of the platform, and the condition that the platform power demand can not be met under the current condition is shown; then, a platform with the platform power demand starting time less than the temporary and transformer substation planned power supply time and a platform with the platform power demand starting time more than or equal to the temporary and transformer substation planned power supply time are found out, and the daily power supply load of the platform is less than or equal to the daily power supply capacity of the temporary and transformer substations, so that the drilling power demand is not met at present, and the platform can meet the requirements in the future in a delayed manner;
the remaining platforms are "not meeting the requirements".
It should be noted that the platform power demand start time, the temporary time and the planned power supply time of the substation are recorded by date. As shown in the figure, three platforms, i.e., an H1 platform, an H2 platform, and an H3 platform, are taken as examples for simplification:
the power supply line 1 is the name of a power supply line for temporary power supply, the planned power supply time of the power supply line 1 is from 1/2020 to 12/2020/31/and the daily power supply capacity of the power supply line 1 is 6000KW;

as shown in fig. 11, the platform power demand time of the H2 platform is 20 days 3 and 20 months (platform power demand start time) in 2020 to 30 days 6 and 30 months in 2020 (platform power demand end time), and the daily power demand of the platform is 12000KW; the daily power supply capacity of the platform for temporary and permanent power supply in the time period is 6000KW and then is 16000KW, namely the daily power supply capacity 16000KW of the platform for permanent power supply after 5, 1 and 5 months in 2020 can meet the daily power demand of the platform, so that the supply and demand balance judgment result of the H1 platform power supply project is 'delayed to meet the demand';
as shown in fig. 12, the platform power demand time of the H3 platform is 20 days (platform power demand start time) 7 and 20 days in 2020 to 31 days (platform power demand end time) 10 and 31 days in 2020, and the platform daily power demand is 12000KW; the daily power supply capacity of the platform for temporary and permanent power supply in the time period is 16000KW all the time, and the daily power demand of the platform can be met, so that the supply and demand balance judgment result of the H1 platform power supply project is 'meeting the demand'.
(4) The supply and demand balance of road construction is judged, and the supply and demand balance of road construction is judged one by one on platforms:
the road plan commissioning time is less than or equal to the platform required road starting time, namely the platform required road time is within the road plan commissioning time, and the road breakpoint maintenance time is beyond the platform required road time, the platform meets the requirement;
the planned commissioning time of the road is more than the time when the drilling machine starts to move away, and after a period of delay, the requirement that the delayed platform requires the road time to be within the planned commissioning time of the road and the maintenance time of the road breakpoint to be out of the delayed platform requirement road time can be met, so that the platform is delayed to meet the requirement;
the remaining platforms are "not satisfied.
And further, the supply and demand balance judgment result is displayed in a visual grading manner by the early warning result quick feedback module.
The early warning result fast feedback module is used for importing single well balance data from the guarantee element model, carrying out grading judgment on the single well balance data according to an early warning strategy, and labeling different judgment results with different colors for grading display; then, making an adjusted drilling engineering operation plan according to the judgment result;
through the calculation in the step S4 and the judgment in the step S5, the supply and demand balance judgment results of each platform in the aspects of water supply, power supply and utilization, road operation and completion of the platform before drilling are determined, in order to enable the judgment result display of each platform to be more in line with the query habits of business personnel and conveniently and quickly find problems, the model sorts the calculated well numbers and the judgment results according to the query habits of the business personnel, and meanwhile, the judgment results of each platform are displayed in a grading mode. Every platform all has the water supply, the power supply and utilization, road operation, 4 judgement in the aspect of the platform completion condition before drilling, supply water in the single platform, supply power and utilization, road operation, there are platform that 3 and above judgement results are unsatisfied with red typeface before drilling the platform completion condition, 2 platforms that judgement results are unsatisfied with yellow typeface, 1 platform that judgement results are unsatisfied with blue typeface, other (all judgement results all satisfy) platforms are the demonstration of black typeface, form the adjustment annual drilling engineering operation plan, in order to reach the quick feedback of early warning result, make things convenient for the corresponding problem of looking over of service personnel.
Example 3:
this example describes in detail a multi-step iterative tuning operation based on example 1 or example 2.
In order to make the determination result more suitable for the service requirement, that is, to meet the initial set target, it is necessary to determine whether the "number of drilled wells", "number of production wells" and "new capacity" in the initial version of drilling project operation plan (i.e., the first version of drilling project operation plan) meet the requirements compared with the "number of drilled wells", "number of production wells" and "new capacity" in the target. In the intelligent scheduling method in the embodiment, based on the multi-step iterative optimization module, when the planned drilling engineering operation plan cannot meet the requirements of 'supply and demand balance' and 'target feasibility' at the same time, the result is output through multi-step iterative convergence for optimization.
The multi-step iteration adjusting and optimizing module inputs the adjusted drilling engineering operation plan from the early warning result quick feedback module, obtains the adjusted predicted drilling quantity, the number of production wells and the newly-built capacity, compares the adjusted predicted drilling quantity, the number of production wells and the newly-built capacity with a preset drilling frame plan, and judges whether the frame plan is met: if so, taking the adjusted drilling engineering operation plan as a well drilling engineering operation plan with a fixed version, and outputting a result; and if not, performing iterative optimization on the main element model and/or the guarantee element model until the adjusted drilling engineering operation plan meets the drilling frame plan.
Specifically, the initial drilling project operation plan is compared and judged with the target drilling quantity, the production well number and the newly built capacity: if the requirements are met, the initial version of the drilling engineering operation plan (namely the first version of the drilling engineering operation plan) can be used as the fixed version of the drilling engineering operation plan to guide construction. If the requirements are not met, main elements such as the number of drilling rigs, the number of drilling wells, the drilling period and the mounting period need to be adjusted, and/or guarantee elements such as temporary water supply points, temporary power supply points, road maintenance plans and mounting time of platforms before drilling need to be adjusted. And step S7, inputting the adjusted element data into the main element model and the guarantee element model again for new arrangement, generating a modified drilling engineering operation plan, and then performing supply and demand balance judgment and feasibility judgment of a preset target. In the multi-step iterative tuning process, any one or more of a plurality of factors such as the number of drilling rigs, the number of drilling wells, the drilling period, the mounting period, the temporary water supply point, the temporary power supply point, the road maintenance plan, the mounting time of a platform tool before drilling and the like can be modified and adjusted, and then a new modified drilling engineering operation plan is formed. And the modified drilling project operation plans formed in the multi-step iterative tuning process are recorded as drilling project operation plans of a second version, drilling project operation plans of a third version, \8230 \ 8230;, and drilling project operation plans of an Nth version. Finally, as stated in step S8, the nth version of the drilling engineering operation plan that satisfies both the supply and demand balance and the preset target is used as the fixed version of the drilling engineering operation plan, and the result is output.
The shale gas continuously exposes various problems of 'more wells, dense platforms, more supporting dependence' and the like in the large-scale production building stage, and business personnel find that the execution performance is poor, and the time and the labor are wasted after an initial drilling engineering operation plan is made. The intelligent scheduling optimization method of the drilling engineering based on the multi-step iteration technology marks a 'problem' well by color grading according to the condition that conditions are met in the aspects of single well water supply, power supply, roads and pre-drilling engineering, and is more accurate in adjustment; meanwhile, the difference between the simulation adjustment plan and the convergence target is continuously shortened through a target convergence technology of continuously returning the main prime model and/or the guarantee element model for parameter adjustment until an optimal adjustment plan is formed. The problems that the amount of information collected by service personnel in the process of making and adjusting the plan is large, the consideration factors are not complete and the like are solved, and the performability, the predictability and the poor flexibility of the plan are improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
