观音山勘探区煤层含气量灰色关联预测
Grey relational prediction of coalbed methane content in Guanyinshan exploration district
摘要
Abstract
Gas content, one of the key indicators used to measure CBM-reservoiring effect, controlled by a variety of geological factors, is often difficult to predict. Taking the Guanyinshan exploration district as a case, the authors identified the main geological controlling factors of CBM content with the gray degree related method, and established GM (1, N) and GM (1,1) models for the gas content prediction in succession in the paper. Further analysis revealed that the burial depth of coal seams, sandstone thickness within 5 meters of roof and roof lithology are key to gas content in the exploration district, and that the GM (1,1) model established from the residual empennage sequence has higher prediction accuracy.关键词
