Problems solved by technology

[0005] The existing drilling engineering parameter monitoring method is only to monitor the drilling engineering parameters at the well site, and the data analyzed is only the data of a single well
Therefore, there is a large deviation between the results obtained by the existing drilling engineering parameter monitoring method and the actual drilling state.

Embodiment 1

[0051] figure 1 The system used in the drilling engineering parameter monitoring method provided in this embodiment is shown.

[0052] Such as figure 1 As shown, the drilling engineering monitoring system includes a well site end 100 and a collaborative monitoring end 200 . Wherein, in this embodiment, the well site end 100 is set at the drilling site, and the cooperative monitoring end 200 is set at a base far away from the drilling site.

[0053] The wellsite end 100 includes a data acquisition module 101 , a first data analysis module 102 and a first data communication module 103 , wherein the first data analysis module 102 is connected between the data acquisition module 101 and the first data communication module 103 . The collaborative monitoring terminal 200 includes a second data communication module 201 , a second data analysis module 202 and an external data acquisition module 203 , wherein the second data analysis module 202 is connected between the second data co...

Embodiment 2

[0073] In this embodiment, both the well site end and the cooperative monitoring end of the drilling engineering monitoring system include a data storage module, Figure 4 Then it shows the flow chart of the drilling engineering parameter monitoring method based on the system.

[0074] Such as Figure 4 As shown, in this embodiment, firstly in step S401, the data collection module 101 collects drilling engineering parameter data in real time, the process and principle are the same as step S201 in the first embodiment, and will not be repeated here.

[0075] In step S402, the first data analysis module 102 stores the collected engineering parameter data in the first data storage module 104 (ie, the well site database), wherein the first data storage module 104 adopts a network version of the database system. Then in step S403 and step S404, the first data analysis module 102 monitors the engineering parameter data in real time and judges whether the engineering parameter data ...

Abstract

The invention discloses a drilling engineering parameter monitoring method, which includes: a data acquisition step, collecting drilling engineering parameter data at the well site; an abnormality judging step, judging whether the engineering parameter data is abnormal according to a preset parameter abnormality diagnosis model; data transmission In the step, if the engineering parameter data is abnormal, the engineering parameter data is sent to the collaborative monitoring terminal; in the collaborative analysis step, the engineering parameter data is determined at the collaborative monitoring terminal according to the received engineering parameter data and the acquired external data related to the engineering parameter The cause of the abnormality can be determined to provide a basis for drilling operations. The method can realize the coordinated monitoring of drilling engineering parameters, makes the monitoring of drilling engineering parameters more comprehensive and accurate, and thus provides reliable basis for drilling operations.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to a method for monitoring drilling engineering parameters. Background technique [0002] Petroleum is an indispensable and important energy source in economic development, and it has a significant impact on the national economy and people's lives. Oil exploration and production is a complex operation, and drilling is an important part of oil exploration and development. [0003] When drilling, because the drill bit is operating underground, it is impossible to directly observe its working condition. The underground rock formations and other formations have complex structures, and there are different rock formations, gas layers and liquid layers. Only by understanding the parameter changes in the drilling process can the reasonable drilling engineering parameters be determined according to the parameter changes, so as to grasp and control the safety of the drilling p...
