Embodiment 1

[0031] Embodiment one is basically as attached figure 1 As shown, a wellbore anomaly analysis and processing system in the production process of shale gas wells includes a basic data module, an anomaly analysis module, a manual verification module, a scheme output module and a data storage module; the basic data module is used to store the basic data of the gas well, Basic data include casing structure data, tubing structure data, test data and production data.

[0032] The abnormal analysis module includes a data acquisition sub-module and an abnormal judgment sub-module. The data acquisition sub-module is used to extract relevant data of the basic data module. The abnormal judgment sub-module includes the method for judging wellbore fluid accumulation, the method for judging tubing corrosion and perforation, and the reseating of constant pressure joints. Judgment method and judging method of tubing clogging and throttling. The abnormality judgment sub-module is based on the ...

Embodiment 2

[0051] Embodiment 2 has made the following improvements on the basis of Embodiment 1: After the shale gas abnormal processing report is generated, the online approval system can be used to carry out the approval process for the shale gas abnormal processing report, and the online approval adopts a web-based electronic signature The chapter mode enables the approval process to be signed online, completes the online approval of the shale gas abnormal handling report, and simplifies the entire approval process.

[0052] Among them, due to the large amount of information in the shale gas abnormal processing report, the online signing and review system is used to convert the shale gas abnormal processing report into the original and the copy. The copy converts the text into a network copy through the network protocol. Separate the text from the picture in the copy, add component reference information for the picture generated by the software component, so that the corresponding comp...

Abstract

The invention relates to the technical field of oil and gas well production, and particularly discloses a shale gas well production process wellbore anomaly analysis and processing system which comprises a basic data module, an anomaly analysis module, a manual verification module and a scheme output module. The exception analysis module comprises a data acquisition sub-module and an exception judgment sub-module, the exception judgment sub-module comprises a plurality of exception condition judgment methods, and the exception judgment sub-module judges exception types and exception conditions according to the judgment methods; the manual verification module comprises an exception pushing sub-module and an expert online confirmation sub-module, the exception pushing sub-module sends exceptions to the user terminal, and the expert online confirmation sub-module is used for online confirmation of experts; and the scheme output module is used for pushing the disposal scheme confirmed by the expert to a user terminal used by a constructor. The scheme is used for solving the problem that in the prior art, various abnormal conditions cannot be rapidly judged and processed in the shale gas well production process.

Description

technical field [0001] The invention relates to the technical field of oil and gas well production, in particular to a wellbore abnormality analysis and processing system in the shale gas well production process. Background technique [0002] Oil and gas field management has a large number of wells, complex well conditions, and a huge amount of development data. Once an abnormality occurs in the production process of a gas well, it is necessary to analyze the abnormal data from the huge data and make an accurate judgment. In the past, when an abnormality occurs, it is often necessary to Experienced engineers analyze abnormal data and make judgments based on their own experience, but this method has high requirements for personnel and low processing efficiency. How to improve the timeliness of abnormal discovery of oil and gas wells and the accuracy of abnormal judgment, and realize intelligent management, It has always been the research direction of various oil and gas field...
