Proppant and preparation method thereof
The invention discloses a proppant and a preparation method thereof. The proppant comprises a hollow ellipsoid A (1), a hollow ellipsoid B (2), a hollow ellipsoid C (3), a hollow ellipsoid D (4) and a ceramic solid part (5), wherein the hollow ellipsoid A (1), the hollow ellipsoid B (2), the hollow ellipsoid C (3) and the hollow ellipsoid D (4) are in 90-degree rotational symmetry distribution in the proppant by taking a central axis (6) as a rotational symmetry axis and a sphere center (7) as a rotational symmetry center, the long radius a is 96-422 microns, the short radius b is 64-212 microns, the short radius c is 64-212 microns, and the relationship among the long radius a, the short radius b and the short radius c is egt; b is greater than or equal to c, and the long radius a is parallel to the central shaft (6); the ceramic solid part (5) is prepared from the following raw material components in percentage by weight: 58.5 to 64.5 percent of Al2O3 powder and 35.5 to 41.5 percent of ZrO2 powder; the density of the propping agent can be designed according to requirements by controlling the size of the hollow ellipsoid.
本发明公开了一种支撑剂及其制备方法，所述支撑剂包括空心椭球体A(1)、空心椭球体B(2)、空心椭球体C(3)、空心椭球体D(4)和陶瓷实心部分(5)；其中，所述的空心椭球体A(1)、空心椭球体B(2)、空心椭球体C(3)和空心椭球体D(4)在支撑剂内部以中心轴(6)为旋转对称轴，球心(7)为旋转对称中心呈90°旋转对称分布，长半径a为96～422μm、短半径b为64～212μm、短半径c为64～212μm，其中长半径a、短半径b和短半径c的关系为a>b≥c，所述的长半径a与中心轴(6)平行；所述陶瓷实心部分(5)包括如下比例的原料组分：Al2O3粉末含量为58.5～64.5wt％，ZrO2粉末的含量为35.5～41.5wt％；本发明能够通过控制空心椭球体的大小，实现支撑剂密度可根据需求设计的目的。
