    • An automatic cementing system and method are disclosed for precisely controlling the density of a slurry during a continuously mixed cement application. The system includes an input water line and a dry cement hopper for supplying water and cement, respectively, to a mixing chamber. The mixing chamber includes two chambers, Chamber A and Chamber B, for thoroughly mixing the water and cement together to form a cement slurry. Chamber B includes a level sensor for measuring the change in slurry level. The input line includes a pump for supplying the water to the mixing chamber, and a flow meter for measuring the rate at which the water is supplied. Similarly, the hopper includes a slide-gate valve for regulating the rate at which the dry cement is supplied to the mixing chamber. A discharge line with a discharge pump and a discharge flow meter receives and discharges cement slurry. A recirculation line is included for density control during initialization. A system controller receives operational parameters from the operator, including desired slurry density, mix water density, and dry cement density. As the slurry discharge rate increases to the desired value, the mix water flow rate increases to maintain the calculated volume percentage of mix water in the discharge slurry constant. The tub level drops, causing the slide-gate valve to open and add cement, raising the tub level to the setpoint level and maintaining an accurate discharge slurry density.

    • An automated density and chemical controller automatically controls the density and chemical proportions of a slurry that is injected into a well during a well fracturing operation. The automated density controller receives from the operator the parameters of the fracturing operation and automatically controls the addition of a proppant to water to produce a slurry with a desired density. The automated density controller measures the incoming flow of water into a blender tub and regulates the delivery of proppant in the blender tub to produce a slurry of the desired density. The performance characteristics of the mechanism used to deliver the proppant are programmed into the controller to enable the controller to regulate the quantity of proppant delivered by controlling the operational speed of the delivery mechanism. The automated chemical controller regulates the addition of chemicals based on the incoming flow rate. The automated density controller also measures the flow of the slurry discharged from the blender tub and, together with the incoming flow rate, calculates the actual density of the slurry. After comparing the actual density with the desired density, the automated density controller calculates a correction factor and recalibrates the performance characteristics of the proppant delivery mechanism. The automated density controller also includes a densiometer for measuring the actual density of the slurry. The density measured by the densiometer is compared with the density calculated by the flow meters to provide an indication of whether the controller is operating correctly.
    • 自动密度和化学控制器在井压裂操作期间自动控制注入井中的浆料的密度和化学比例。 自动密度控制器从操作者接收压裂操作的参数,并自动控制向水中添加支撑剂以产生具有所需密度的浆料。 自动密度控制器测量进入搅拌桶的进入流量并调节支撑剂在搅拌桶中的输送以产生所需密度的浆料。 用于输送支撑剂的机构的性能特征被编程到控制器中,以使得控制器能够通过控制输送机构的操作速度来调节所传送的支撑剂的数量。 自动化学品控制器基于进入的流量调节化学品的添加。 自动浓度控制器还测量从搅拌桶排出的浆料的流量,并且与进入的流速一起计算浆料的实际密度。 在将实际密度与期望密度进行比较之后,自动密度控制器计算校正因子并重新校准支撑剂输送机构的性能特征。 自动密度控制器还包括用于测量浆料的实际密度的密度计。 将由密度计测量的密度与由流量计计算的密度进行比较,以提供控制器是否正常工作的指示。

    • A heat exchanger tube bundle extractor having an improved sled and motive means operable to move the tube bundle into or out of its shell. A fixed screw shaft is provided on the chassis, and a rotatable drive nut on the sled. The drive nut is threadedly retained on the screw shaft. The drive nut is held against axial movement with respect to the sled by a gear box disposed on the sled. The gear box output includes a rotating shaft to which the drive nut is connected, which provides the drive nut with the appropriate speed and power to effectively pull the tube bundle from, or push it back into, the shell. A balance nut disposed on the opposite end of the drive shaft from the drive nut, and threadedly engaged with the screw shaft, reacts against side forces on the sled and screw shaft to assist in keeping the drive nut and screw shaft properly aligned. All of the power generation, conversion, and control equipment for operating the sled drive, a hydraulic breakout cylinder, and a hydraulic elevator is located on the sled itself in a compact and self-contained arrangement, and is movable along with the sled. This eliminates the piping, cabling, and related power equipment from the chassis. The present invention exhibits a low unit weight to pulling/pushing power ratio, and a low unit weight to load capacity ratio.
