Study on Compound Technique of Perforating and Fracturing in Coal Seams

摘要

Compound technique of perforating and fracturing can effectively control the perforating direction and the fracturing expansion in oil and gas industry. In order to effectively solve the methane problem in coal seams, the feasibility of this technique used in fracturing coal seams was tested in lab, the experiments of perforating and fracturing were separately carried out on samples of coal and the experimental effects are satisfactory. Compound technique of perforating and fracturing is promising in coal seams.
