摘要： A gas compressor is employed downhole in a well for pressurizing formation gas. The gas compressor is driven by a downhole electrical motor. The downhole assembly also includes a pump. The pump might be located below the motor and driven by the same motor. In that event, the pump pumps liquid being produced by the formation downward to a liquid disposal formation. Also, the pump may pump the liquid to the surface, with the gas being delivered into a repressurizing zone.

摘要： The operating characteristics and the nominal, best operating point of a multi-stage centrifugal pump are shifted to lower flow rates without loss of nominal head and without substantial loss of efficiency by machining or otherwise shortening the trailing edge of all or some of the stationary guide vanes of the diffusers between impeller stages. By so doing, a single pump size can be adapted to a range of flow requirements, as desired. Thus, it is possible to reduce the number of pump sizes manufactured, and yet supply the needs of customers.

摘要： A method for producing gas from a well with low pressure involves running a bottom hole pressure test to graph a P-Q curve. The operator computes a frictional pressure drop due to friction of the gas flowing through the production tubing to the surface. A packer is set above perforations in the well. A screw pump is selected that has a capacity equal to the sum of the frictional pressure drop plus a desired wellhead pressure. The screw pump has a flow rate capacity determined from the P-Q curve. The operator may vary the frequency of a downhole motor to achieve the desired wellhead pressure.

摘要： A protection system for an artificial lift device including but not limited to electrical submersible pump (ESP) and an electrical submersible progressing cavity pup (ESPCP). The artificial lift device is suspended on a tubing string into a wellbore where the artificial lift device contacts well fluids. The artificial lift device is provided with a barrier such as an intake barrier or output barrier that deters an ingress of well fluids into the artificial lift device. As a result, the artificial lift device may remain idle and submerged within well fluids for an extended period of time without experiencing degradation of the artificial lift device internals. The intake barrier may include a plug, burst disk, dissolvable material, a selectively openable barrier such as a sleeve or a spring biased member or other member that is capable of providing a suitable barrier. The barrier may be removed once the artificial lift device is ready for operation. The artificial lift device may be filled with a protective fluid. An optional pressure sensor may be provided that is in communication with the interior of the backup unit for communicating with a compressor that may be activated to maintain a positive pressure within the artificial lift device to prevent well fluids from entering the unit. The protection system of the invention is desirable for protecting an idle artificial lift device, including when the artificial lift device is a backup unit in a multi-artificial lift device deployment.
摘要翻译：一种用于人造提升装置的保护系统，包括但不限于电潜泵（ESP）和电潜水进步腔穴（ESPCP）。将人造提升装置悬挂在油管柱上，进入井筒，人造提升装置接触井液。人造提升装置设置有阻挡物，例如进气阻挡物或输出屏障，其阻止井流体进入人造提升装置。结果，人造举升装置可以保持空闲并浸没在井液中长时间，而不会经历人造提升装置内部的劣化。进气阻挡件可以包括塞子，爆破盘，可溶解材料，可选择地可打开的屏障，例如套筒或弹簧偏置构件或能够提供合适屏障的其它构件。一旦人造提升装置准备好运行，就可以去除屏障。人造提升装置可以填充有保护流体。可以提供可选的压力传感器，其与备用单元的内部连通，用于与压缩机连通，压缩机可被启动以在人造举升装置内保持正压力以防止井液进入该单元。本发明的保护系统对于保护空闲的人造电梯装置是理想的，包括当人造电梯装置是多人造电梯装置部署中的备用装置时。
