The invention belongs to the technical field of oil fracturing propping agents and relates to a method for preparing a light fracturing propping agent for a multi-hole oil and gas well. The fracturing propping agent is prepared by taking alumina as a main material, adding one or a plurality of components of limestone, dolomite, magnesite, wood dust and plant chip as pore-forming substance, one or a plurality of components of bentonite and kaolinite as plasticizer, and one or a plurality of components of starch and dextrin as binder; grinding the materials into fine powder, mixing and stirring evenly, rolling to form balls in a granulator, then sintering in a tunnel kiln or a rotary kiln after drying, and finally screening to control the particle size distribution to obtain the light fracturing propping agent for multi-hole oil and gas well. The invention has simple material formula and preparing process and no pollution and is suitable for large-scale production.
