摘要： Blending particulate and liquid to make slurry for use in oilfield operations is addressed. The blender has an upwardly facing particulate expeller with a flat base, raised hub, and generally radially extending, circumferentially spaced vanes extending upwardly from the base. The vanes extend from leading edges spaced about a vane inner diameter to tips spaced about a vane outer diameter. Adjacent expeller vanes define expeller passageways therebetween. The particulate expeller does not serve as a meaningful liquid impeller and the blender does not act significantly as a pump. The expeller has a several preferred diameter, clearance, height and length dimensions and ratios. Wide, deep expeller inlets and shallow, narrow outlets enhance particulate entry and minimize expeller torque. Vane extensions impart velocity to the particulate upon contact and minimize sensitivity to particulate entry velocity. Maximized circumferential overlap of adjacent vanes reduces liquid back-flow.
摘要翻译：混合颗粒和液体以制备用于油田作业的浆料。搅拌器具有面向上的微粒排出器，其具有平坦的基部，凸起的毂，以及从基部向上延伸的大致径向延伸的周向隔开的叶片。叶片从围绕叶片内径间隔开的前缘延伸到围绕叶片外径间隔开的尖端。相邻的叶片叶片限定了其间的推出器通道。颗粒排出器不用作有意义的液体叶轮，并且搅拌器不会像泵那样显着地起作用。排出器具有几个优选的直径，间隙，高度和长度尺寸和比率。宽，深的推进器入口和浅，狭窄的出口增强了颗粒进入并最大限度地减少了推力器扭矩。叶片延伸部在接触时赋予颗粒速度，并使对颗粒进入速度的敏感性最小化。相邻叶片的最大化圆周重叠减少了液体回流。

摘要： The present invention relates generally to well servicing operations, and, more particularly, to devices, systems and methods useful in stimulation blending for fluids, mixtures, and/or slurries used in well servicing operations. A device, system and/or method is provided comprising a suction centrifugal pump capable of receiving an inlet fluid and providing a suction pressure arranged to substantially minimize a geyser effect in a proppant inlet and a mixer capable of receiving the inlet fluid provided by the suction centrifugal pump and mixing the inlet fluid with a proppant received from the proppant inlet, the mixer arranged to be substantially optimized for mixing. The device, system and/or method also comprises a discharge centrifugal pump capable of receiving the inlet fluid mixed with the proppant from the mixer and discharging the inlet fluid mixed with the proppant from the mixer downhole, the discharge centrifugal pump arranged to be substantially optimized for pumping. The system also comprises at least one downhole pump capable of receiving the inlet fluid mixed with the proppant from the mixer discharged downhole by the discharge centrifugal pump.
