Embodiment Construction

[0013] figure 1 An artificial lift system (ALS) 1 deployed in a wellbore 5 is shown according to one embodiment of the present disclosure. A wellbore 5 is drilled from the surface 20 of the land into a reservoir 25 containing hydrocarbons (ie natural gas or coal bed methane 100 g). A set of casings 10c is inserted into the shaft 5 and set therein by cement (not shown). The shell 10c is perforated with holes 30 to provide fluid communication between the reservoir 25 and the holes of the shell 10 . A wellhead 15 is mounted at the end of the casing group 10c. A production string 10t extends into the wellbore 5 and hangs from the wellhead 15 . A production packer 85 is provided to isolate the annulus between the tubing string 10t and casing 10c from the reservoir 25 . A production tree 35 is mounted on the wellhead 35 and a production line (not shown) may extend from the tree's chokes to production equipment such as separators (not shown). The reservoir 25 can self-produce un...

Abstract

A pump includes one or more stages, each stage including a tubular housing and a mandrel disposed in the housing. The mandrel includes a rotor rotatable relative to the housing and having: an impeller, a shaft, and one or more helicoidal blades on an outer surface of the impeller. The mandrel further includes a diffuser: connected to the housing, having the rotor shaft extending therethrough and having a plurality of vanes on an outer surface thereof. Each vane has an arcuate portion and a longitudinal portion. The diffuser further has a channel formed between an adjacent pair of vanes. The pump further includes a fluid passage formed between the housing and the mandrel.

Description

[0001] Cross References to Related Applications [0002] This application claims US Provisional Patent Application Serial No. 61 / 663,956 filed June 25, 2012, which is hereby incorporated by reference in its entirety. Background technique [0003] Field of the Disclosure [0004] Embodiments of the present disclosure generally relate to diffusers for cable-floated drainage pumping systems. [0005] Description of related technologies [0006] As gas wells are fully developed, many experience reduced production as the accumulation of water creates backpressure on the reservoir. The natural gas industry has utilized different techniques to alleviate this problem, however, most of these techniques have not crossed economical hurdles due to the fact that they require intervention such as pulling a pipe string. Contents of the invention [0007] Embodiments of the present disclosure generally relate to diffusers for cable-floated drainage pumping systems. In one embodiment, th...
