Ultralow-density ceramsite proppant and preparation method thereof
The invention discloses an ultra-low density ceramsite proppant and a preparation method thereof, the ultra-low density ceramsite proppant comprises the following raw materials by mass: 30%-50% of flint clay, 20%-30% of calcined talc, 10%-20% of red clay, and 10%-30% of bauxite ore. According to the raw material composition ratio and the preparation method provided by the invention, the technical problem that the ceramsite proppant is difficult to maintain relatively high strength at ultra-low volume density is solved. Specifically, the volume density of the ultra-low density ceramsite proppant provided by the invention can be as low as 1.40 g/cm < 3 >, the breakage rate under 69 MPa is lower than 8%, and the ultra-low density ceramsite proppant has high-temperature corrosion resistance. In conclusion, the ceramsite proppant provided by the invention can reduce the oilfield exploitation cost and increase the yield of an oilfield, and is particularly suitable for oil exploitation in a high-corrosion environment.
本发明公开了一种超低密陶粒支撑剂及其制备方法，以质量百分比计，其原料包含30％～50％的焦宝石，20％～30％的烧滑石，10％～20％的红胶泥，10％～30％的铝矾土矿。本发明提供的原料组成配比和制备方法，解决了陶粒支撑剂在超低体积密度难以保持较高强度的技术问题。具体地，本发明提供的超低密陶粒支撑剂体积密度可低至1.40g/cm3，69MPa下破碎率低于8％，且具有高温抗腐蚀的能力。综上，本发明所提供的陶粒支撑剂能降低油田开采成本，并且使油田增产，特别适合于高腐蚀环境的石油开采。
