Problems solved by technology

[0002] In the process of geological exploration, driven by economic interests, many drilling teams have the phenomenon of less drilling, no drilling, and false drilling, which seriously affects the drilling quality
At present, the control of drilling quality and the identification of drilling authenticity are mainly manual monitoring. However, manual monitoring of exploration quality not only costs a lot of labor costs, but also has a great influence of human factors in the monitoring process, which is highly subjective and cannot guarantee monitoring. objectivity of results

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment, the present invention is further described: a kind of drilling site monitoring method, monitoring is from perforation to end hole, adopts on-the-spot photographing equipment to take the image of drilling site, sends to the image analysis and processing system of background, image analysis The processing system analyzes the drilling results every t hours, and outputs judgment conclusions, so that the quality supervisors can know the situation of the drilling site in time, so as to control the quality of drilling. Wherein, t can be specifically set as required. The specific steps are:

[0030] 1) Image duration analysis: analyze whether the shooting time and drilling time are normal:

[0031] If T-A-B<0, the shooting time is insufficient, and the judgment conclusion that cannot be analyzed is output;

[0032] If T-A-B>δ t , then output the judgment conclusion that the drilling time is insufficient;...

Abstract

The invention discloses a drilling field monitoring method which includes the steps: monitoring the process from tapping to hole termination, shooting images of a drilling field and analyzing a drilling result once every t time; judging whether drilling time is enough or not by analyzing image time; judging whether a drilling machine normally works or not by analyzing the drilling machine; judging whether drilling is normal or not by analyzing the length of a rock core; judging whether an external environment conforms to an actual field situation or not by analyzing the external environment. The monitoring method can process drilling field images in batch, objectively and accurately analyze and judge field drilling conditions, timely discover the problems of drilling omission, false drilling and the like and achieve fine early warning effects, the manpower cost of field quality supervisors can be reduced, the influence of artificial subjective factors on monitoring results can be effectively avoided, and authenticity and reliability of geological data are ensured.

Description

technical field [0001] The invention relates to the technical field of drilling monitoring, in particular to a drilling site monitoring method. Background technique [0002] In the process of geological exploration, driven by economic interests, many drilling teams have the phenomenon of less drilling, no drilling, and false drilling, which seriously affects the drilling quality. At present, the control of drilling quality and the identification of drilling authenticity are mainly manual monitoring. However, manual monitoring of exploration quality not only costs a lot of labor costs, but also has a great influence of human factors in the monitoring process, which is highly subjective and cannot guarantee monitoring. objectivity of the results. In order to ensure the quality of drilling, ensure the authenticity of drilling results, and effectively control the quality of drilling itself, it is necessary to develop a system that can monitor and identify the authenticity of dr...
