Abstract

The invention discloses a coal mine inter-well data interpolation method and system, and the method comprises the steps of respectively building a parameter curve of two adjacent drilling wells in a research area based on drilling well data, and building a parameter conversion model between the two adjacent drilling wells; based on the parameter curve and the parameter conversion model and based on the coal seam similarity, performing interpolation in the inter-well range of the two adjacent drilling wells, so that parameters of different positions and different depths can be effectively compared, a full-coverage three-dimensional parameter database based on the coal seam is established in a certain research area, and then the modeling accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of coal seam and coal seam gas development, and in particular relates to a data interpolation method and system between coal mine wells. Background technique [0002] In recent years, with the continuous increase of coal mining depth, various coal mine safety problems such as sharp increase of stratum stress and high gas concentration have become increasingly prominent. Due to the complex structure of most coal mining areas in southern my country, the development of structural coal in coal seams and the high content of mine gas often cause potential risks such as high risk of gas outburst. At present, although a series of solutions have been formed for different types of risks in coal mines, it is difficult to ensure safe and orderly further mining of coal mines without an accurate analysis of the entire coal mine system or geological system. Therefore, it is necessary to carry out in-depth research on tran...
