Abstract

The invention discloses a drilling and logging data depth matching method and system. The drilling and logging data depth matching system comprises a curve processing module, a pseudo three-dimensional seismic interpretation work area creating module, a pseudo seismic interpretation position generating module, a modeling module, a depth matching factor data volume generating module, a data volume matching module and a logging curve conversion module. According to the drilling and logging data depth matching method and system, the problem that logging curve depth matching is low in working efficiency according to an existing software technology method can be solved under the situation of hundreds of drilled wells. The efficiency of logging curve depth matching is remarkably improved, the drilling and logging data depth matching quality is guaranteed by the utilization of the functions of a seismic interpretation system, and reliable basic drilling and logging data are provided for reservoir geological research and reservoir modeling.

Description

technical field [0001] The invention relates to the technical field of reservoir geological research and reservoir modeling, in particular to a drilling and logging data depth matching method and system. Background technique [0002] Logging curve depth matching mainly includes two methods: manual matching and automatic matching. Manual matching is to compare multiple curves by visual inspection based on experience, find out the curve segments with similar or identical characteristics, and correspond the depths of similar or identical curve segments one by one. Automatic matching usually uses the correlation function for depth matching, and uses the degree of correlation between the two logging curves to judge whether the depth of the two curves is on the same layer. For example, GeoFrame software uses the method of automatic matching of related functions. However, the problem with this manual matching and automatic matching method is that it needs to do depth matching for...
