Abstract: Cementing takes place after a hanger (38) and seal (39) are set to first insure the pressure integrity of the connection between the string to be cemented and the existing tubular. Cementing top down or bottom up is envisioned with either displaced fluid returning toward the surface in a crossover tool (25-29) or with the displaced fluid squeezed into the formation. A work string manipulates the crossover for reversing out after cementing. For running in a valve assembly (1, 2) is held open to permit circulation. Work string manipulation allows at least one valve that keeps the cement in the annulus to close and at least one other valve to close that keeps the reverse fluid from leaving the cemented tubular to allow such flow to return to the crossover and out to the surface. Valve release can be done with a pressure responsive sleeve instead of a stinger (100) on the running string.

Abstract translation: 固定装置发生在衣架（38）和密封件（39）被设置为首先确保待接合的绳索与现有管状体之间的连接的压力完整性的情况下。 设想自顶向下或向下倾斜，在交叉工具（25-29）中或移动的流体被挤压到地层中时，设想的流体返回到表面。 工作串操纵混凝土后的交叉换向。 为了在阀组件（1,2）中运行，保持打开以允许循环。 工作串操作允许至少一个将水泥保持在环形空间中的阀门关闭，并且至少一个其他阀门关闭，从而使反向流体不会离开胶合管状体，以允许这种流动返回到交叉并流到表面。 可以使用压力响应套管而不是运行管柱上的托管架（100）来完成阀释放。
