Embodiment 1

[0011] Raw materials: light burnt bauxite 100kg, magnesium slag 2.0kg, manganese oxide 1.0kg, carboxymethyl cellulose 0.3kg. Among them, the calcination temperature of light-burned bauxite is 800℃, and the calcination time is 1.0 hour. After calcination, Al 2 O 3 The content is ≥75%, and the magnesium slag is the waste slag discharged from the production of metal magnesium by the Pidgeon method.

[0012] Preparation method: mix light-burned bauxite, magnesium slag, manganese oxide and carboxymethyl cellulose in proportions and smash, pass through a 600-mesh sieve, with a sieving rate greater than 80%; then add the pulverized materials to a ball machine. In the process of adding atomized water vapor is sprayed, the obtained ball is passed through a 18-35 mesh screen; then the ball is dried to make the water content less than 3%; finally the dried ball is sintered to obtain the product, the sintering temperature is At 1400°C, the holding time is 0.5 hours, and the product is na...

Abstract

The invention achieves the reuse of magnesium slag discharged when magnesium metal is produced through Pidgeon process, and discloses a high strength ceramsite oil proppant using magnesium slag as mineralizer and a preparation method of the high strength ceramsite oil proppant using the magnesium slag as the mineralizers. In terms of raw materials, the ceramsite oil proppant comprises, by weight, 100 parts of light roasting bauxite, 2-6 parts of the magnesium slag, 1-3 parts of auxiliary materials, and 0.3-0.5 part of binding agent. The preparation method includes the following steps: mixing the light roasting bauxite, the magnesium slag, the auxiliary materials and the binding agent proportionally, making ball materials, and sintering the dried ball materials to obtain products. The sintering temperature is 1300-1400 DEG C, the heat preservation time is 0.5-1 hour, and the products naturally cool down to the room temperature. The crushing rate of the high strength ceramsite oil proppant produced by the preparation method of the high strength ceramsite oil proppant using the magnesium slag as the mineralizers is smaller than or equal to 5% under a closing pressure of 86 megapascals, the volume intensity is smaller than or equal to 1.8 grams per cubic centimeter, and the apparent intensity is smaller than or equal to 3.35 grams per cubic centimeter. The preparation method is simple and low in production cost.

Description

Technical field [0001] The invention relates to a proppant used in a fracturing process for oil and natural gas wells, in particular to a high-strength ceramsite proppant using magnesium slag as a mineralizer and a preparation method. Background technique [0002] my country is the world's largest producer and exporter of magnesium metal. The production of magnesium metal is almost entirely based on the Pidgeon process technology. For every ton of magnesium smelted, 8-10 tons of magnesium slag are produced. For the treatment of this kind of industrial waste, the methods of dumping in wasteland and landfilling depressions and burial are mainly adopted, and the utilization rate is very low. Summary of the invention [0003] The invention realizes the reuse of the magnesium slag discharged when the Pidgeon method produces metal magnesium, and provides a high-strength ceramsite petroleum proppant using the magnesium slag as a mineralizer and a preparation method thereof. [0004] In or...
