Problems solved by technology

The production method of this patent is: the main material and the auxiliary material are mixed and ground into fine powder, and after being loosened with water, the pellets are made into pellets by a ball forming machine, and then sent to the kiln according to the sintering temperature of 1100-1500°C and the sintering time of 0.5-5 Hours of firing under the process conditions, the compressive strength of the fired product has reached more than 69MPa, and the broken rate of the finished product is ≤10%, which cannot meet the high-strength index requirements of deep oil wells. Production efficiency is relatively low
[0005] The quality of the proppant produced by American Carbo Company represents the international advanced level. However, due to the use of corundum sintering, although the performance can meet the requirements, the source of raw materials is difficult, the processing technology is complicated, the equipment investment is large, the energy consumption is large, and the cost is high.

Embodiment Construction

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

[0014] The chemical composition of the proppant formula of the present invention comprises by weight percentage: 5-45% of high-titanium blast furnace slag, 10-30% of high-alumina brick, 17-77% of bauxite, 4-8% of composite sintered The composite sintering agent includes 0-50% dolomite, 10-75% magnetite and 0-50% kaolin. The high-titanium blast furnace slag can be industrial waste high-titanium blast furnace slag, and the high-alumina brick can be used Recycled high alumina bricks.

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

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 ...
