The invention relates to a fixed-scale scaling ruler for geological record drawing. The ruler comprises a track ruler and a sliding ruler which are combined through a mortise and tenon joint structureand can be disassembled quickly, a sliding groove is formed in the middle of the track ruler, the two sides of the sliding groove are track ruler scale long edges with the same width, scales are marked on the front faces and the back faces of the track ruler scale long edges, and the front faces and the back faces of the two track ruler scale long edges correspond to four digital proportional rulers respectively. The sliding ruler comprises a sliding graduation ruler, a sliding ruler head and a sliding ruler clamping groove, and the sliding ruler clamping groove is located between the slidinggraduation ruler and the sliding ruler head; the width of the sliding groove is equal to that of the sliding ruler head; and the width of the track ruler scale long edges is equal to that of the sliding ruler clamping groove. The ruler is detachable, and when the track ruler and the sliding ruler are not combined, the track ruler and the sliding ruler can be independently used as common rulers; and when the track ruler and the sliding ruler are occluded together, histograms of different scales can be rapidly drawn according to the scales of the track ruler.
Description
technical field [0001] The invention relates to the field of geological records and drawings, in particular to a fixed scale scale for geological records and drawings. Background technique [0002] Drilling core catalog is an essential work in geological drilling. [0003] Drawing borehole histograms and describing core features in corresponding core sections is one of the important tasks in drilling core cataloging. [0004] The drilling histogram should be drawn according to a certain scale. [0005] Generally, the scale of the ruler is 1:1, that is, 1 unit length, which represents its real length. In the process of drawing a histogram with a scale of 1:N, 1 unit length actually represents N unit lengths. When drawing a core of a certain length, it is necessary to divide the length by N to obtain the length of this length on the drawing, and then draw it. This greatly reduces the efficiency of core cataloging work. Therefore, it is necessary to design a fixed-scale zo...
