Description
Technical field
The utility model relates to a kind of oil field low yield block oil well produced liquid collection transfer device, and specifically a kind of closed loop divides the supercharging of water ground watering outer defeated integrated apparatus.
Background technology
Continuous rise along with crude oil price, increasing low yield block, peripheral remote block drop into exploitation, the oil well of this class block generally has common characteristics---" three low one long ", oil well output low, moisture low, wellhead temperature is low, individual well gathering line length is long.Can advance separately gathering line production the summer that such oil well is higher at temperature, but temperature one reduces, even well head has heating furnace, because the oil well liquid measure is low, pipeline is long, and in pipeline, the crude oil flow velocity is slow, heat loss is fast, crude oil in pipeline just starts to solidify, wax deposition, and blocking pipe, cause oil well to produce.Therefore for such oil well, each oil development unit adopts water mixing production more, advance the tank list draws productions, many mouthfuls of oil well series connection to produce or the extract well modes such as production of connecting guarantee the normal production of its low temperature season.
The current water mixing mode of production is applied in the more perfect zone of crude oil gathering system more, as multi-purpose station, near block station, can the station on a set of water mixing system, stand the outer water-mixing flow of laying to measuring station, the individual well well head, because every mouthful of well is all to lay double-flow (water mixing, oil-collecting), the surface construction investment is large, and as the water mixing of accompanying hot use long distance circulation conveying repeatedly between oil well and multi-purpose station, separate, dehydration, supercharging, heating, along Cheng Wendu, the pressure loss is large, corrosive pipeline is serious, running cost is high, various reasons has limited this mode applying in each oil field.
Well head is installed single tank, and crude oil is transported outward by tank car after advancing tank, and this method of operation is suitable for the very remote individual well of distance set oil system, but nearer stripper well is very uneconomic for the distance set oil system.At first be that tank car draws oily cost high, efficiency is low; Next is every mouthful and singly draws well at least will take two workers to see in turn well, cause labour's waste; The 3rd is singly to draw the associated gas in the well manufacturing process all to efflux, and has not only wasted resource but also polluted atmosphere.
Many mouthfuls of oil well series connection can be applicable to the block that oilwell produced fluid amount is relatively high, if many mouthfuls of individual well production fluid amounts are too low, when temperature is low, the liquid measure of closing away still can be lowered the temperature very soon, particularly there is intermittently producing well to be mixed in wherein, when several mouthfuls of wells whiles are intermittently not fuel-displaced, close away the bad luck that pipeline is not still broken away from blocking pipeline.
Utilizing many mouthfuls of oil well production of extract well series connection is the modes of production more widely of application at present.If the extract well that a bite liquid measure is high, temperature is high is arranged in the zone of a slice stripper well, produce the winter of this sheet oil well so substantially just guarantee.But the management difficulty of extract well is larger, the most nerve-wracking is etching problem.The extract well is to penetrate out high watercut layer mostly, because formation water salinity is high, corrosivity is strong, and electric submersible pump extract well expends a set of electric pump unit basically in 1 year, a winter at least examined pump twice by sucker rod pump extract well, and the expense that electric pump unit, oil pipe, sucker rod drop into is high; In addition, extract well surface line seriously corroded, average life span only has 2-3.
Summary of the invention
