Fracturing propping agent for oil gas well and preparation method thereof

Abstract

The invention relates to a fracturing proppant used for oil and gas wells, which is prepared with the following materials by weight: 80 to 88 portions of low content bauxite, 1 to 4 portions of manganese ore, 2 to 3 portions of potash feldspar, 2 to 4 portions of solid soluble glass, 1 to 5 portions of calcium mountain meal, and 1 to 5 portions of French chalk. The quality of the fracturing proppant is stable; the break resistance is high; the acid corrosion resistance is high; the volume density is low; the fracturing proppant can effectively prop up fracture, and significantly improve the permeability in the fracture so that oil and gas flow smoothly, and the oil productivity is improved. In addition, the raw materials and the preparation method are simple, and low requirements are proposed about the raw materials, and the fracturing proppant is prepared simply.

Description

(1) Technical field

[0001] The invention relates to a fracturing proppant for oil and gas wells and a preparation method thereof. (2) Background technology

[0002] In oil and natural gas deep well exploitation and ultra-deep well fracturing process, proppant is used to provide high permeability channels for the circulation of oil and gas flow, maintain high conductivity, and increase oil and gas production. my country's petroleum industry generally refers to proppants with a pressure bearing capacity of 69Mpa and 86Mpa as high-strength fracturing proppants. CN1844298 discloses a super-strength ceramsite proppant and its preparation method, which is made of the following raw materials: bauxite 10-30%, bauxite 50-70%, high-iron bauxite 8-15%, clay 7-20%, 2-5% manganese ore, 0.5-2.5% potassium feldspar, 0.1-1.2% dextrin, and the raw material requirement is bauxite containing Al 2 o 3 85-90%, bauxite containing Al 2 o 3 : 74-77%, high iron bauxite containing Al 2 o 3 : ...
