Example 2:
the embodiment provides a specific operation of the shale gas drilling engineering tracking deduction method based on embodiment 1, as shown in fig. 1, and includes the following steps.
Step S1: and collecting basic data of the platform, basic data of the well and basic data of the drilling machine.

And the drilling machine matching rule is used for setting a drilling machine priority arrangement strategy in a user-defined mode according to the contents of the drilling machine basic data.
And step S4: setting a drilling main prime model comprising installation parameters, drilling machine parameters, drilling starting parameters and drilling completion parameters.

The drilling machine parameters comprise: a carry-in period Cs _ zjbr and a carry-out period Cs _ zjbc.
The drilling parameters comprise: the uphole section drilling time Cs _ zjsd, the downhole section drilling time Cs _ zjxd, the lower rig drill tripping delay period Cs _ kzyc.
The drilling completion parameters comprise: completion cycle Cs _ wjzq, and cleanup/well time Cs _ tgxzq.
Step S5: well grouping: firstly, carrying out well grouping on wells according to the motor positions according to the well types, the well positions and the platforms to which the wells belong in the basic data of the wells, and customizing the well group drilling sequence and the drilling sequence of each well in the group.
It should be noted that, during actual operation, when the well group drilling sequence is customized in step S5, drilling on different groups of well groups of the same platform has a precedence relationship, and the drilling phase difference time between two adjacent groups of well groups is the drilling delay period of the lower drilling machine. Typically, different groups of wells are indicated by different numbers, the smaller the number the earlier it is to be tripped in.
It should be noted that, during actual operation, when the drilling sequence of each well in the group is defined in the step S5, the drilling of the wells in the same group has a precedence relationship, and all upper sections of the well are drilled in sequence first, and then the lower sections of the well are drilled in reverse sequence. Generally, the drilling sequence sets a field to indicate that the smaller the number the more ahead the drill is made.
Step S6: a drilling project plan schedule is initialized or imported.
Step S7: an initial arming time is set or imported and a planned well group is selected based on the well group in step S5.
In practical operation, in step S7, an initial tool installation time is called from an external system or manually input for setting; the principle followed when selecting a planned well according to the initial rig time obtained is: when there is a time, the planned well must have no rig allocated for that time period.
Also, one or more sets of drilling rigs are typically assigned to the same well group.
Step S8: judging whether an idle well exists in the planned well group: if yes, jumping to step S9, otherwise, jumping to step S10.
Recording: and in the planned well group with idle wells, the number of the well groups is Z, the serial numbers of all the well groups are set to be Z according to the well group drilling sequence defined in the step S5, the number of the wells in the same well group is N, the serial numbers of all the wells are set to be N according to the well group drilling sequence defined in the step S5, and Z, Z, N and N are positive integers.
That is, the platform and well parameters are set as follows:
after the wells are grouped, the wells are marked as a 1# well group, a 2# well group, a 8230; and a Z # well group; well group number Z, and Z =1,2, \ 8230;, Z;
n wells are arranged in the same group of wells, and marked as a 1# well, a 2# well, a 8230; and an N # well according to the drilling sequence;
the well has the serial number N, and N =1,2, \8230, N.
Step S9: according to the planned well group with the idle well selected in the step S8, the drilling machine matching rule base in the step S3, the drilling main prime model in the step S4, the self-defined well group drilling-out sequence and the drilling-out sequence of each well in the group in the step S5, the drilling engineering schedule in the step S6 and the initial setting time in the step S7, the drilling schedule arrangement of the group of wells is firstly carried out; and then according to the scheduled drilling schedule, scheduling the drilling schedules of other groups of well groups, and finally completing the scheduling of the drilling schedules of all the well groups.
The scheduling of the drilling schedule for the same group of wells in the step S9 mainly refers to scheduling of drilling time, drilling completion time, drilling start moving time and drilling machine moving out time.
Taking an example of arranging a drilling machine in a group of well groups, the arrangement of the drilling schedule of the z-th group of well groups (z # well group) at the moment specifically comprises the following steps:
step a: calculating planned drilling time according to the setting time of the group of wells, the drilling start delay period of the lower drilling machine obtained in the step S4 and the well group serial number z;
A. plan drill-up time Jh _ sz = ampere time Jh _ Jasj + (z-1) × lower rig drill-down delay period Cs _ kzyc;
step b: calculating planned drilling time according to the planned drilling time in the step a, the drilling time of the upper section of the well obtained in the step S4 and the well serial number n;
B. planned open time Jh _ kz = planned upper drill time Jh _ sz + (n-1) upper interval drill time Cs _ zjsd;
step c: calculating planned drilling completion time according to the planned drilling time calculated in the step b, the drilling time of the underground section, the well number N and the well serial number N obtained in the step S4;
C. the planned drilling completion time Jh _ wz = planned drilling opening time Jh _ kz + (N-N + 1) and the drilling time of the downhole section Cs _ zjxd;
step d: calculating planned completion time according to the planned completion time calculated in the step c and the completion period obtained in the step S4;
D. planned completion time Jh _ wj = planned completion time Jh _ wz + completion period Cs _ wjzq;
step e: calculating the planned well completion time of the first well (N = 1) calculated in the step d, the through-scrape/well washing time and the well number N obtained in the step S4, and calculating the planned rig start moving-off time;
E. the planned rig start removal time Jh _ ksbl = planned completion time Jh _ wj of the first well (1 # well) in the same group + total number of wells N of the same group through scratchwash/well time Cs _ tgxz;
step f: calculating the planned drill moving-out time according to the planned drill moving-out starting time calculated in the step e and the moving-out period obtained in the step S4; the planned moving-out time of the drilling machine is the planned successful moving-out and becomes an effective circulation drilling machine node;
F. planned drill move-out time Jh _ bc = planned drill start move-out time Jh _ ksbl + move-out period Cs _ zjbc.
When a group of rigs has multiple rigs, the rig on time of the next rig = last on time of the previous rig + the same group again on days. That is, according to the basic attributes and matching rules of the drilling machines in the drilling machine matching rule base, when K (K is more than or equal to 2) drilling machines are arranged for the same group of well groups, the setting time of the next drilling machine in the same group of well groups is the setting time of the previous drilling machine plus the setting time of the same group. Other time node calculation methods refer to the above, and are not described in detail.
The initial mounting time indicates the time when the mounting condition is satisfied. If several wells are ready to be installed for one machine position and several wells are suddenly drilled in advance, the rest wells need to wait for 2 years after the previous wells are put into production, and the installation time is set again. If the project schedule arrangement process is simplified in the system, the arrangement of the node with the resettlement time can be omitted, but in order to better adapt to the complex situation in the actual project, the arrangement deduction problem of the node with the resettlement time is considered in the invention creation, the resettlement time of the next well is obtained by deduction calculation of the time after the last well is put into operation and the resettlement days Cs _ tczcja of the same group or the resettlement days Cs _ yczcja of the different group in the resettlement parameters.
