AI Technical Summary

Problems solved by technology

The existing proppants are mainly three types of proppants: high density, medium density and low density. In order to meet the strength requirements, the existing proppants have relatively high density, poor suspension, easy sedimentation, and are not easy to be carried into the well , the mining cost is high

Abstract

The invention discloses a super-low-density proppant. The proppant is characterized by mainly being prepared from the following raw materials in part by mass: 20 to 25 parts of calcined bauxite, 30 to 35 parts of raw bauxite and 45 to 50 parts of clay. The invention also discloses a method for preparing the super-low-density proppant. The proppant of the invention has low specific weight of only 1.35 to 1.45, apparent specific gravity of 2.5 to 2.65, low density and good suspension property, is not easy to precipitate and is easy to carry into a well.

Description

technical field [0001] The invention relates to an ultra-low-density proppant for deep oil and gas well fracturing technology, and also relates to a preparation method of the ultra-low-density proppant. Background technique [0002] In order to develop deep oil and gas wells and increase production, fracturing technology is widely used. In order to ensure the effective propping of fractures in deep underground formations, suitable proppant is necessary. It can increase the conductivity of the formation and increase the production of oil or gas, which is an important factor in the application of fracturing technology. [0003] The ideal proppant for oil and gas well fracturing requires high carrying capacity and high sand ratio, so it needs to have the lowest possible density and the highest possible strength. The existing proppants are mainly three types of proppants: high density, medium density and low density. In order to meet the strength requirements, the existing prop...
