The main disadvantage of this solid proppant is: the soft clay and quartz in the ingredients are not well bonded to the high-temperature reaction of the main material of aluminum alum, which will easily lead to unstable product quality and large quality fluctuations; secondly, although the main crystal phase of the product is Mullite phase, but because the raw material contains a certain amount of soft clay and qua...

Abstract

The invention is about to improve the solid ceramic particle proppant of deep oil and gas well fracturing technique, the solid proppant composed of crude bauxitic clay fine powder and 6-10wt% manganese dioxide mineral fine powder. The manganese dioxide reacts with the bauxitic clay main material more completely under high temperature, largely reducing glass phase, and beneficial to raise the compactness of the resultant at the same time, able to largely heighten the guide-flow ability. The solid proppant: bulking density 1.65-1.8g/cu cm, apparent density 3.0-3.15g/cu cm, and breaking resistance (SY/T5108-1997) 86MPa not greater than 10%, the maximum able to reach 100MPa not greater than 10%.

Example Embodiment

[0012] Example 1: Take the content of titanium dioxide 4.5%, Al 2 O 3 70% raw bauxite 100%, plus 6.5% manganese dioxide mineral, crush the two raw materials into 300 mesh fine powder separately, mix the materials evenly, add enough water required for granulation to mix into moist soil. The pellets are put into the water chestnut forming ball machine and rotated into balls, sieved to obtain particles with a particle size of 0.5-1 mm, sent to a rotary kiln for 1.5 hours at 1350°C for sintering, and discharged out of the kiln for cooling, sorting and dust-removing packaging.

Example Embodiment

[0013] Example 2: As in Example 1, 10% manganese dioxide was added and sintered at 1320°C for 1.5 hours.

[0014] The fired product of the above embodiment contains Al 2 O 3 68%, Fe 2 O 3 2.5%, SiO 2 12%, total manganese 3.5%, bulk density 1.75 g/cm 3 , Apparent density 3.10 g/cm 3 , Anti-breaking ability (SY/T5108-1997) 69 Mpa≤5.2%, flow conductivity 60Mpa≥75μm 2 -cm, turbidity <20 degrees.
