摘要： A downhole electrical wet connector comprising a plug which is slidingly inserted into a socket, the socket comprising a series of wiper seals spaced apart by separation zones, each zone being individually supplied with dielectric fluid from a separate reservoir. A retractable insert is arranged in the socket and displaced by the plug during connection. The fluid pressure in each zone is individually regulated relative to ambient wellbore pressure and the pressure in adjacent zones and optionally equalized to minimize loss of fluid.
摘要翻译：一种井下电湿式连接器，其包括滑动地插入到插座中的插头，所述插座包括通过分隔区隔开的一系列擦拭器密封件，每个区域从单独的容器单独地供应介电流体。在插座中布置可伸缩插入件，并在连接期间由插头移位。每个区域中的流体压力相对于环境井筒压力和相邻区域中的压力单独地调节并且可选地相等以使流体损失最小化。

摘要： A wet connection system suitable for use in hydrocarbon wells preferably comprises one or more elongate, small diameter conduits (50) which extend down the wellbore (2) and terminate adjacent a locating structure (11) on the production tubing (10). Equipment (70) deployed at the locating structure is connected to one or more self supporting conductors (30) which extend down the conduits from the wellhead (5). Preferably the conductors are retractable and the conduits are sealingly connected to the equipment, allowing the equipment and conductors to be deployed and recovered independently of each other and to be flushed with dielectric oil (99) pumped down the conduits after re-connection.

摘要： A wet connection system comprises a fixed tubing with an orientation profile and redundant, first and second fixed wet connectors, and an electrical submersible pump assembly (ESP) comprising a wet connector and an orientation element for engaging the orientation profile. The ESP can be reconfigured, for example, by interchanging its component modules so as to change the position of its wet connector with respect to the orientation element, whereby the wet connector on the ESP can be engaged alternatively with either one of the fixed wet connectors when the orientation element is engaged with the orientation profile in the same deployed position of the ESP.
摘要翻译：湿连接系统包括具有定向轮廓的固定管道和冗余的第一和第二固定湿式连接器，以及包括湿连接器和用于接合定向轮廓的定向元件的电潜泵组件（ESP）。 ESP可以被重新配置，例如，通过交换其组件模块以改变其湿连接器相对于定向元件的位置，由此ESP上的湿连接器可以与固定的湿式连接器当定位元件与ESP的相同展开位置中的取向轮廓接合时。
