摘要： In accordance with embodiments of the present disclosure, a debris separator device for use with a casing system may include an impeller having a plurality of blades to generate a vortex of mud in the section of the casing system when the casing system is lowered into a wellbore. The device may also include a baffle disposed in the section of the casing system, the baffle having an annular cup shape that forms an outer circumferential pocket to capture debris from the vortex of mud. The impeller and baffle may enable the debris separator device to separate debris and other debris from a flow of mud through the casing system so that the debris does not clog a float collar of the system. The disclosed debris separator device may be flushable so that the device does not become clogged with debris and can thereby maintain auto-fill through the casing system.

摘要翻译：根据本公开的实施例，与套管系统一起使用的碎片分离器装置可以包括具有多个叶片的叶轮，以在套管系统下降到井眼中时在套管系统的部分中产生泥浆涡旋。该装置还可以包括设置在壳体系统的区段中的挡板，挡板具有环形杯形状，该环形杯形状形成外周袋以从泥浆涡中捕获碎屑。叶轮和挡板可以使碎片分离装置能够将碎屑和其他碎屑与通过套管系统的泥浆流分离，使得碎屑不会堵塞系统的浮环。所公开的碎片分离器装置可以是可冲洗的，使得装置不会被碎屑堵塞并且因此可以维持通过套管系统的自动填充。

摘要： A method for consolidating particulate matter in a well wherein the method comprises the following steps: Injecting a composition into a sand bearing formation, where the composition comprises a curable non-aqueous, homogeneous liquid, an initiator for heat induced production of free radicals, a pot life extending inhibitor for stabilization of free radicals, and optionally an accelerator and optionally a filler wherein said non- aqueous, homogeneous liquid further comprises an at least partially unsaturated pre- polymer selected from the group consisting of polyester and epoxy vinyl ester, and at least one vinyl or allyl containing monomer. Subsequently injecting an aqueous, non- aqueous liquid or a gas for re-establishing permeability of the formation and letting the composition cure by free radical polymerization in the sand bearing formation at a temperature of 0-150° C to form a cured sand consolidating material. The composition as described in the first step of the said method can also be used as a sand consolidation material in general, without following the method as previously described.
摘要翻译：一种方法是将颗粒物质固结在一个井中。该方法包括将组合物注入含砂地层中。组合物包含可固化的非水均匀液体，用于热诱导产生自由基的引发剂，用于稳定自由基的适用期延长抑制剂，以及任选的促进剂和任选的填料。非水均匀液体还包含至少部分不饱和的预聚物，其包括聚酯和环氧乙烯基酯以及至少一种含乙烯基或烯丙基的单体中的至少一种。该方法还包括随后注入水性非水液体或气体，以重新建立地层的渗透性，并使组合物在含砂地层中的自由基聚合在0-150℃的温度下固化，以形成固化砂整理材料。
