    Abstract: Disclosed is a tubing system for transporting a gas-liquid flow from a well to a production platform or processing facility. It includes a dual pathway section between the well and the production point having a first tubing portion and a second tubing portion. The second tubing portion includes a plurality of parallel channels so as to divide the multi-phase flow into a plurality of flows through individual channels. This is done to reduce flow slippage of the lower viscosity portion of the flow, which may lead to inefficiencies in flow characteristics, and often, undesirable cyclical variations in pressure and fluid volume. This is especially useful in inclined portions of the petroleum flow pipe system and along hilly terrain. The first round tubing portion is used for transporting the gas-liquid flow as well as for maintenance purposes, such as for pigging, fishing or coiled tubing operations.

    Abstract translation: 公开了一种用于将气液流从井输送到生产平台或处理设施的管道系统。 它包括井和生产点之间的双通道部分,其具有第一管部分和第二管部分。 第二管道部分包括多个平行通道,以便将多相流分成通过各个通道的多个流。 这样做是为了减少流动的较低粘度部分的流动滑动,这可能导致流动特性的低效率,并且通常会导致压力和流体体积的不希望的周期性变化。 这在石油管道系统的倾斜部分和丘陵地带尤其有用。 第一圆管部分用于输送气液流动以及用于维护目的,例如用于清管,捕鱼或连续油管作业。

    Abstract: The present invention is used in conjunction with a multi-channel system of a production string for deployment in gas, condensate or oil wells. An end-piece is placed at the entrance to such multi--channel system. It includes a semi-enclosed space helping to increase the proportion of gas phase entering the system at its bottom entrance. Increased proportion of gas allows lifting liquids and/or solids from the wellbore with greater efficiency. Examples of using the invention include wellbore water removal for gas wells with liquid loading problems, for solution gas drive or gas cap driven oils wells during their initial "natural flowing phase", or during gas re-injection or gas-lift recovery operations for oil wells. It can also be used for gas-lifting water in water wells.
