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.

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 and mechanical properties of the product, thereby improving the recovery rate and efficiency of the oil well, and greatly reducing the formation damage caused by oil extraction It can also reduce power consumption during fracturing construction. Using industrially discarded high-titanium blast furnace slag and recycled high-alumina bricks to replace mineral raw materials can further reduce costs.
[0016] The production method of the present invention is as follows: 1) After mixing the raw materials uniformly, perform one-stage superfine dry grinding and two-stage wet grinding, and then use a spray granulation system to produce cue balls, and put the cue balls into the sugar coating machine. Squeeze and wrap to strengthen granulation to obtain green pellets. This treatment process avoids the shortcomings of loose spray granulation particles, low sphericity and poor appearance quality, and can improve production efficiency while ensuring the quality of the green balls. 2) After drying the obtained green pellets through a drying system, they enter a high-temperature kiln for sintering. The sintering temperature is controlled at 1100-1400°C and the sintering time is controlled at 0.5-4 hours. 3) Then the temperature is cooled down, and the surface is polished by high-speed rotation in the friction cylinder to achieve dust separation. 4) The temperature is raised to 80-100°C, and the surface treatment process is carried out with acid-resistant organic substances (such as phenolic resin), and then cooled and solidified to form a dense and smooth micro-surface coating, which makes the surface of the product chemically inert and does not interact with water or pressure. Cracking liquid, acidified liquid, oil and natural gas, etc. react, and at the same time make the product have good hydrodynamic characteristics, and reduce the flow resistance in the process of injection and oil output.
[0017] Examples 1-6: Examples 2, 4, and 6 in Table 1 are three examples of the present invention. The results show that the high-titanium petroleum fracturing proppant produced by the formula and method of the present invention has good Acid resistance (acid solubility) and strength (anti-cracking rate), the acid solubility of the product is below 5%, and the 69MPa anti-cracking rate %≤3.0%. Examples 1, 3, and 5 in Table 1 are products obtained by using the formula and method of the present invention, but without performing the surface treatment process (ie, step 4), and their performance is relatively poor. The sintering temperature of all the above examples is 1200°C, and the sintering time is 3 hours.
[0018] Real
[0019] Note: The above results are the results of testing in accordance with SY/T 5108-1997, "Recommended Methods for Testing the Performance of Fracturing Proppants", the oil and gas industry standard.
