Research on Deviation Correction and Modeling of Geological Drilling

Abstract:

For three-dimensional geological modeling by TP model, the problem of deviation in the original drilling data must be resolved. In this paper, the original logging data of drilling is utilized to study the spatial relationship between the geological bodies constructed by equivalent vertical and real drilling respectively, and a correction method on deviated drilling is therefore proposed. The result shows the method can effectively conduct the lossless correction of deviated drilling under various drilling and stratum conditions, thus providing reliable logging data of drilling without deviation for the construction of TP models.
