Shahai Formation Of CBM Resources Evaluation And Development Research In Dongliang Area Of Fuxin Basin

To solve the coal resource depletion and an urgent need to replace the energy issue in the city of Fuxin,this article carried out the work of CBM resource evaluation and development research in Dongliang area of Fuxin Basin.The main coal seams hosted in three sections of Shahai in Dongliang area of Fuxin Basin,a total of three coal seam group,17 layers,rich in coal reserves.Based on the analysis of previous coal and CBM geological data and experimental analysis of test data in Dongliang area,illustrates the influence of geological factors of coalbed methane distribution area;By using the theory of pressure-adsorption curve to determine the area of coalbed gas and buried relations between the deep;Using volume method to calculate the area of CBM resource of 8.46 × 108m3;According to the latest domestic and foreign various types of evaluation,demonstrates the development of coalbed methane resources in the area with better conditions for ground drilling in reserves low capacity for small-scale gas field;Through this area drainage test five production wells finishing,carry out reasonable productivity analysis,drainage design research.This comprehensive demonstration of CBM resources in the area has a certain development prospects,provided basic data and theoretical guidance for the further development of CBM development.
