Abstract

The invention belongs to the technical field of well drilling auxiliary agents and discloses a ceramsite fracturing propping agent preparation method. The method includes steps: subjecting albite, bauxite, kaolin, coal ash, dolomite, potassium permanganate, cryolite, low-melting-point alloy powder, graphite, cupric oxalate, ferric oxalate, calcium carbonate and modified bamboo fiber powder to mixed ball milling, and filtering through a 120-mesh screen to obtain mixed powder; stirring and mixing sodium fluoride solution and peach gum liquid according to a mass ratio of 1:20-1:30 to obtain mixedslurry; mixing mixed powder with mixed slurry according to a mass ratio of 3:2-3:1, granulating, drying, carbonizing and sintering to obtain a blank material; stirring and mixing the blank material with modified sodium alginate liquid according to a mass ratio of 1:20-1:30, filtering and drying to obtain a ceramsite fracturing propping agent. Mechanical properties and permeability of the ceramsite fracturing propping agent are both improved effectively.

Description

technical field [0001] The invention discloses a preparation method of a ceramsite fracturing proppant, belonging to the technical field of drilling aids. Background technique [0002] At present, oil and gas extraction technology is becoming more and more mature, but the output of conventional oil fields is still difficult to break through. In addition, other unconventional energy sources, such as wind energy and nuclear energy, have not been used in human production on a large scale due to their limitations. With the continuous exploitation of oil fields, there are fewer and fewer shallow wells and strong permeability deposits, and it is difficult to extract oil and gas without fracturing technology. At present, in the process of oil and gas exploration and exploitation, hydraulic fracturing technology is the main means to increase production and enhance recovery. Petroleum fracturing proppant is the key material of hydraulic fracturing technology, and its performance di...
