Problems solved by technology

[0002] Sliding drilling is gradually developing towards digitalization and intelligence. It relies on engineering data to guide sliding directional operations. The quality of sample data is particularly important. The three systems are independent of each other and usually have different dimensions and orders of magnitude. In addition to the different collection frequencies, there are large gaps in data integrity, accuracy, and timeliness. When the levels of various indicators differ greatly, Directly using the original index value for analysis will highlight the role of indicators with higher values ​​in the comprehensive analysis, and relatively weaken the role of indicators with lower value levels, which will affect the reliability of the data. The data that is directly combined is not suitable for direct use. Computing and model training, a large amount of data generated by each system is difficult to achieve fusion, sharing and integrated management, and cannot be directly compared and analyzed
At the same time, due to factors such as acquisition software restart and communication failure, it is easy to cause problems such as loss of garbled characters, which has a great impact on the accuracy and reliability of data.

Embodiment 1

[0036] A method for processing sliding orientation data, comprising the following steps:

[0037] (1) Take the torsion system data table as the reference table to obtain a single row of time stamps;

[0038] (2) Traverse the data tables of MWD system and mud logging system according to the time stamp, merge and store the traversed data, and obtain the integrated data table of the three systems of torsion, MWD and mud logging;

[0039] (3) Traverse the integrated data table, clean garbled characters, redundant numbers and invalid data, update the data table, and realize data cleaning;

[0040] (4) Data standardization to form an effective data set.

[0041] In step (1), the time stamp (n=1, 2, 3 .

[0042] In step (2), for the nth row of data of the torsion system, traverse the MWD and mud logging system data tables according to the time stamp, that is, screen other system data according to the time stamp, and find the same and Similar time stamps, judging basis: the latest ...

Embodiment 2

[0063] In step (1), the time stamp (n=1, 2, 3 .

[0064] Step (2) Traverse the MWD and mud logging system data tables according to the timestamp, and merge and store the traversed data to realize data integration.

[0065] Further, in step (2), for the nth row of data of the torsion system, traverse the MWD and mud logging system data tables according to the time stamp, that is, screen other system data according to the time stamp, and find the MWD and mud logging system data tables The same and similar time stamps in the same and similar time stamps, the judgment basis: the latest value less than the time, such as judging whether the difference between the time stamp of row n in the torsion data table and the time stamp of other system data tables is 1 second.

[0066] Furthermore, in step (2), since the data comes from multiple systems and the data structures and attributes are different, the data types should be divided according to the data structure and attributes when me...

Abstract

The invention discloses a sliding orientation data processing method, which comprises the following steps of: (1) collecting a single-row timestamp by taking a torsional pendulum system data table asa reference table; (2) traversing data tables of the MWD system and the logging system according to timestamps, and combining and storing the traversed data to obtain an integrated data general tableof the torsional pendulum system, the MWD system and the logging system; (3) traversing the integrated data general table, cleaning messy codes, redundancy numbers and invalid data, and updating the data table to realize data cleaning; and (4) standardizing the data to form an effective data set. According to the method, multi-system data integrated management can be achieved, data cleaning is conducted on integrated data, messy codes, redundancy numbers and invalid data are deleted, the data quality is improved, on the basis, standardization processing is conducted on original index data obtained after data cleaning, and the normalization and applicability of sliding drilling data are improved.

Description

technical field [0001] The invention relates to a sliding orientation data processing method, which belongs to the field of oil and gas drilling data processing. Background technique [0002] Sliding drilling is gradually developing towards digitalization and intelligence. It relies on engineering data to guide sliding directional operations. The quality of sample data is particularly important. The three systems are independent of each other and usually have different dimensions and orders of magnitude.
