    摘要： As a representative mode of practicing the methods of the invention disclosed herein, a tubular screen is lowered through a production string and packer and positioned in a well bore adjacent to a perforated formation interval containing loose formation materials. To inhibit the production of such materials as the well is produced, a mixture of loose materials and a hardenable consolidating agent is then deposited around the tubular screen so as to fill the perforated well bore interval leaving only the upper portion of the screen projecting above the annular body of deposited materials. In this manner, once the consolidating agent hardens, production can be commenced through the permeable plug of consolidated materials into the screen and out its exposed upper end.

    摘要： An apparatus can include a first curved blade for use in a centrifuge. The centrifuge can be for collecting debris particles in a fluid flowing through the centrifuge. The first curved blade can include a plurality of eccentric slots. The first curved blade can include a groove positioned at an outer edge of the curved blade. The first curved blade can also include a first mating element and a second mating element. The first and second mating elements can be for coupling the first curved blade to a second curved blade about a central axis.

    摘要： A new method separating sand, solids, and produced particulates down-hole in a well producing hydrocarbons. The separation assembly can include ether one, two, or more segments or stages of varying lengths depending upon the individual application. The assembly is installed into the tubing string or delivery conduit of a well producing hydrocarbons. One stage can consist of a velocity chamber whereby separation of particulates occurs by increasing the downward velocity of particulates and reducing the upward velocity of hydrocarbons thereby allowing the particulates to “fall-out” into a lower chamber where the particulates are captured. Another stage can consist of a filter whereby particulates are captured in a chamber that can consist of filtering materials such as gravel, rock, sand, wood, or manmade materials. Each of the stages can be employed individually or in combination.

    摘要翻译： 在生产良好的碳氢化合物中分离砂，固体和生成颗粒物的新方法。 根据各个应用，分离组件可以包括长达一个，两个或更多个不同长度的段或多个阶段。 将组件安装到生产烃的油管柱或输送管道中。 一个阶段可以由速度室组成，通过增加颗粒的向下速度并降低烃的向上速度，从而允许颗粒“掉出”到被捕获微粒的下部室中，从而分离颗粒物。 另一个阶段可以由过滤器组成，其中颗粒被捕获在可由过滤材料如砾石，岩石，沙子，木材或人造材料组成的室中。 每个阶段可以单独使用或组合使用。
