摘要: Well completion cement may be pumped through a side pocket mandrel that includes parallel rows of filler sections to exclude cement from void space within the side pocket tube. The filler sections are drilled with cross-flow jet channels and surface upsets to stimulate scrubbing turbulence by well working fluid behind a cement wiper plug. The wiper plug includes leading and trailing groups of wiper discs secured to an elongated shaft. The two wiper groups are separated by a distance that permits the leading seal group to gain traction seal before the push seal on the trailing wiper group is lost. A spring centralizer spans a center section of the shaft between the two wiper groups to maintain axial alignment of the shaft as the plug traverses the length of a mandrel.
摘要翻译: 完井水泥可以通过包括平行的填料段的侧袋心轴泵送,以从侧袋管腔内的空隙排除水泥。 填充部分钻有横流喷射通道和表面扰动,以通过水泥刮水器插头后面的井下工作流体刺激洗涤湍流。 刮水器插头包括固定到细长轴上的雨刷盘的前后组。 两个刮水器组分开一段距离,允许前导密封组在拖把组件的推压密封件丢失之前获得牵引密封。 弹簧对中器跨越两个擦拭器组之间的轴的中心部分,以在塞子穿过心轴的长度时保持轴的轴向对准。

摘要: In systems and methods for production of hydrocarbons fluids from a formation surrounding a wellbore, a production assembly is cemented into place, and excess cement is then cleaned from the production tubing and liner. Thereafter, hydrocarbon fluids are produced and artificial gas lift assistance is provided. All of this may be accomplished in a single trip (mono-trip) of the production tubing.
摘要翻译: 在用于从围绕井筒的地层中生产碳氢化合物流体的系统和方法中,将生产组件胶合到位,然后从生产管道和衬管清洁多余的水泥。 此后,生产烃流体并提供人工气举辅助。 所有这些都可以在生产管道的单次行程(单程)中完成。

摘要: A check valve having a piston with a greater coefficient of thermal expansion than the body which closes a bleeder port at running temperatures and opens the bleeder port when flow stops or when the valve cools. A body of brass and a piston of filled TFE is a preferred combination.
摘要翻译: 止回阀具有活塞,该活塞具有比在运行温度下关闭泄放口的主体更大的热膨胀系数,并且当流动停止时或当阀冷却时打开泄放口。 一个黄铜体和一个填充TFE的活塞是一个优选的组合。
