Accompanying drawing explanation
Fig. 1 is the FB(flow block) of drill site monitoring method of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described: a kind of drill site monitoring method, monitoring is from perforate to whole hole, adopt the image of shooting equipment shooting drill site, send to the image analysis processing system on backstage, image analysis processing system carries out the analysis of a results of drilling every t duration, and export judgement conclusion, make quality monitoring personnel understand the situation of drill site in time, to control the quality of probing.Wherein, t can specifically set as required.Concrete steps are:
1) image duration is analyzed: analyze shooting time, whether drilling time is normal:
If T-A-B < 0, then shooting time is not enough, exports the judgement conclusion that cannot analyze;
If T-A-B > is δ
t, then the judgement conclusion of drilling time deficiency is exported;
If T-A-B≤δ
t, then probing conforms to actual, enters next step and analyzes.
Wherein, T is the image duration from perforate to whole hole; A is the required theoretical duration of probing, is drawn by the conversion of whole hole core length according to regional exploration experience; B is that drilling equipment leaves unused and maintenance duration, is recorded draw by Field Force; δ
