Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of petroleum fracturing proppant, and relates to a preparation method of a light porous oil and gas well fracturing proppant. The proppant is especially suitable for fracturing production of shallow wells with high conductivity. Background technique

[0002] With the widespread use of hydraulic fracturing technology in the oil and gas industry, fracturing proppant has become an indispensable material for oil and gas well stimulation. In the process of hydraulic fracturing, the underground rock formation is cracked by high-speed and high-pressure liquid. Before the rock formation cracks are closed, the fracturing fluid carrying proppant particles enters the rock formation cracks, and then supports the cracks. Oil and gas pass through these supports with the help of formation pressure. The gap between the agents is discharged, so as to realize the fracturing of oil and gas.

[0003] At present, oil and gas we...
