Example Embodiment

[0013] The present invention will be further described below in conjunction with embodiments.

[0014] The chemical components of the proppant formula of the present invention include: 5-45% high-titanium blast furnace slag, 10-30% high alumina brick, 17-77% bauxite, 4-8% composite sintering The composite sintering agent includes 0-50% dolomite, 10-75% magnetite and 0-50% kaolin. The high-titanium type blast furnace slag can be industrially discarded high-titanium type blast furnace slag, and the high alumina brick can be used Recycle high alumina bricks.

[0015] The high titanium blast furnace slag changes the solid solution structure of the product after proppant sintering, and the TiO in the high titanium blast furnace slag is used 2 Compatible with Al in high alumina bauxite 2 O 3 And SiO 2 The formation of titanium-containing corundum, mullite and other solid solutions, on the one hand, can reduce the heat treatment temperature, on the other hand, it can improve the physical...

Abstract

The invention provides a high-titanium type petroleum fracturing propping agent, whose chemical constituents comprise (by weight ratio) 5-45% of high-titanium blast furnace slag, 10-30% of high-alumina brick, 17-77% of bauxite, and 4-8% of composite agglutinant, its preparation process comprises the following steps, (1) grinding the raw material, making mother balls with an atomizing granulation system, charging the mother balls into a sugar-coating machine, squeezing and dressing so as to obtain blank pellets, (2) drying the blank pellets through a drying system, loading into high temperature kiln for agglutination, (3) cooling down and carrying out surface polishing through high speed rotation in a friction tube, (4) elevating the temperature to 80-100 deg. C, carrying out surface treatment with acid-resisting organics, finally cold-setting.

Description

technical field [0001] The invention relates to a petroleum fracturing proppant and a production method thereof, in particular to a high-titanium petroleum fracturing proppant and a production method thereof. Background technique [0002] With the development of oil and natural gas deep well fracturing technology, the scale of fracturing is getting larger and larger. The quartz sand proppant that was once commonly used cannot meet the requirements due to material reasons. [0003] Journal of Guizhou University of Technology (August 2003, Volume 32, Issue 4 Chen Ye et al.) reported a new oil fracturing proppant, adding chromite and TiO 2 , its 69MPa anti-fragmentation rate is 4.10%, which is not conducive to environmental protection and increases production costs. [0004] The patent number is 01108604.1, and the invention title is "Manufacturing Method of High-Strength Ceramsite Proppant", which discloses a ceramsite proppant and its production method. It uses 100 parts by ...
