Alloy of AOC special type prevents arenaceous oil well pump to apply successfull
From;    Author:Stand originally
Alloy of AOC special type prevents arenaceous oil well pump to use the trade information ceaseless development as oil field successfully in oil field, a lot of sandstone oil deposit because the structure is loose and suffer the effect that discharges a quantity for a long time to be collected by force greatly, make wildcat goes out arenaceous serious with each passing day, as a result of,give arenaceous wildcat of arenaceous bead wear away, the anticorrosive wear-resisting layer of pump canister and force plunger is destroyed, spend to well fluid mineralization tall, corrode serious wildcat, what create anticorrosive wear-resisting layer quickly is big fall off, the leakage of pump is broken increase quickly, still can cause arenaceous check force plunger, arenaceous bury the phenomenon such as sucker rod, make oil well pump premature invalidation. Technology of You Andong oil (group) the alloy of AOC special type that limited company develops development independently prevents arenaceous oil well pump to use alloy coating material to combine special structure to design, the arenaceous card that solved an arenaceous well well, arenaceous bury reach arenaceous bead to wear away the phenomenon such as pump canister, force plunger, improved the service life of oil well pump.
This kind new-style preventing arenaceous oil well pump is the design that uses tube of short pump of long force plunger, there is one part force plunger to be besides pump canister from beginning to end in the working process of pump, heavy arenaceous enter pump canister and force plunger space not easily, can avoid to stop after smoking arenaceous card or arenaceous the happening that buries force plunger; 2 it is the design inside pump canister has blow the arenaceous, plant that blow dirty automatically, still design sky having link at the same time heavy arenaceous passageway, make arenaceous bead sedimentations in pipe of heavy arenaceous tail, reduced the odds of arenaceous card of oil well pump, have defend arenaceous performance very well; 3 it is pump canister wall uses special spray technology, spray has the AOC-165C alloy coat that is more than 0.25mm, coating material undertook fighting grinding, the anti-corrosive, design that prevents dirty, alloy coating and matrix are united in wedlock for metallurgy, adhesion is strong, there is intermediate zone between combinative scale, electrochemistry of not easy generation is corroded, the spray of Ni-60 alloy powder that force plunger surface uses tall wear-resisting corrode and into, after force plunger material and pump canister material match through optimizing, make the corrosion resistance of pump canister and force plunger can be mixed fight the abrasiveness that wear bead to be able to rise greatly, the leakage that can reduce oil well pump is broken, heighten pump effect; 4 it is every Er assembly uses special material to be made, can effective slow down wears away with corrode, have fight erode, fight percussive function. Alloy of AOC special type prevents arenaceous oil well pump to already succeeded to be depended on in Ma of distant river, Daqing, carat, the oil field such as Ji Dong throws field test, lead 100 % successfully, prevent arenaceous effect remarkable. Like auroral oil field prevent 18 break piece basically mix with wadi of billabong of fan delta leading edge arenaceous deposit of leading edge layer is given priority to, chu Cengyan stone is oil reservoir of this Du Jiatai fine sandstone and pink are fine in hard arenaceous qualitative feldspar sandstone, cementation owner should be qualitative mixture of crystallization calcite and mud, oil reservoir buries deep 1300-1600m, oil reservoir is average and effective ply 16.6m, porosity is 22.45% . Water of this piece layer is NaHCO3, total mineralization spends 5127mg/l. End at present, prevent 18 break piece cast petroliferous well in all 69, open a well 53, cast affusion well in all 40, open a well 25. Prevent 18 break piece since be being developed oneself, because sex of oil reservoir content is poorer, grease well gives arenaceous appearance in developing a process relatively serious, restrained wildcat to produce can play, and what go out layer arenaceous have fine white arenaceous, slop is arenaceous, big arenaceous etc different, in the light of differ an arenaceous well, prevent 18 break piece seeking all the time prevent arenaceous craft advancedly. An Dongshi oily technology (group) the alloy of AOC special type that limited company develops development independently prevents arenaceous oil well pump to defend arenaceous approach newly to gave arenaceous well to offer, in prevent 18 stop a devoted field test, success leaving a well leads 100 % , apparent benefit sees in the spot. Prevent the wildcat such as 3-08-07 of the 18 dawn 3-05-6 that snap an option, dawn all is piece arenaceous bring about the wildcat that wears away to leakage is broken or block pump, comparative Jing Jiping all check pump cycle already lengthened 1 times above than groovy oil well pump, heighten pump effect on average 10 % above. It is with dawn 3-08-07 well exemple, go out as a result of layer arenaceous, after groovy oil well pump is being entered below, wildcat goes out arenaceous bring about calorie of pump to close a well, after arenaceous oil well pump is being prevented into alloy of diametical 44mmAOC special type below, day produces fluid 29.5m3, day is petroliferous 4.2m3, pump effect 88.1 % , already serial production many days 100, at present still aborning. Dawn 3-05-6 enters serial production of oil well pump of alloy of diametical 44mmAOC special type 70 days below the well, day all adds fluid 10.2m3, add oily 2.6m3, heighten pump effect on average 19.2% , reduced work number, improved the service life of oil well pump. From the point of the sand content that collects a fluid, achieved prevent arenaceous purpose.
