Description
Technical field
This utility model relates to oil field mining liquid oily-water seperating equipment technical field, is a kind of
SAGD
Circulate pre-hot production fluid oil removing settling pot.
Background technology
SAGD
(SAGD)
, it is the cutting edge technology developing super-viscous oil both at home and abroad, uses
SAGD
Technology heavy crude producing or super-viscous oil, can increase substantially recovery ratio.
SAGD
Production cycle includes that circulation preheating produces two stages with normal,
SAGD
Circulation warm-up phase typically lasts for
3-6
Individual month, after the connection of vapour chamber, proceed to the normal production phase.
Circulation warm-up phase Produced Liquid and
SAGD
All there is larger difference in the aspects such as normal production phase Produced Liquid basic physical properties, oil-water emulsion characteristic, dehydration mechanism, and this stage Produced Liquid is easy and float, silt particle etc. form greasy filth, crude oil recovery intractability is big, relies on existing Technology and equipment cannot meet the process of this stage Produced Liquid.
Circulation warm-up phase Produced Liquid has the following characteristics that
(
1
)
SAGD
Circulation warm-up phase Produced Liquid is alkalescence, and water type is bicarbonate sodium form, and suspension content is high, in crude oil gum level high (>=
20%
),
50
DEG C degassed crude viscosity exists
50000 mPa.s
Above；
(
2
) this stage need to inject a large amount of superheated steam accelerate vapour chamber grow, during the not yet maturation of vapour chamber, stratum heat absorption capacity is limited, it is impossible to the waste heat of absorption can in the form of saturated steam with Produced Liquid from well head extraction.Therefore, it is more serious that this stage well head Produced Liquid takes vapour amount ratio, takes vapour amount and generally exists
40%
Above, reach as high as
80%
, Produced Liquid temperature height (
160
DEG C extremely
180
DEG C, can reach
220
DEG C), oil content relatively low (
1%
Extremely
20%
)；
(

) circulation warm-up phase Produced Liquid silt carrying capacity big (
1%
Extremely
5%
), predominantly quartz sand class, the footpath containing sand grains is mainly distributed on≤
1
μ
m
Neighbouring interval, under circulation fluid treatment agent effect, the mixture of oil, water, mud, sand and float can be enriched with on oil-water interfaces, and a large amount of clay components serve as emulsifying agent effect, increases crude oil recovery difficulty；
(

) this stage Produced Liquid is after long-time standing, Produced Liquid is stable
W/O
Type,
O/W
Type mixing and emulsifying state, under this state, positive, reverse-phase emulsifier and the predrainage medicament of routine all can not reach intended purpose, and oil-water separation difficulty is the biggest；
(

m
The two scope, oil droplet size distribution is significantly less than exploitation Produced Liquid of handling up.
Simultaneously as this stage Produced Liquid profit density contrast is less, causes Produced Liquid oil-water emulsion stability preferable, be difficult to Gravity Separation.Therefore,
SAGD
Circulation warm-up phase Produced Liquid between
W/O
Type,
O/W
Between type water-oil phase mixed type emulsion, as sewage disposal, oil content, float are too high；As crude oil processed, demulsifier type selecting difficulty, and current oily water separating equipment all can not meet
SAGD
The oil-water separation condition of circulation warm-up phase Produced Liquid, for example with common vertical oil removing tank, it can not meet the requirement of Produced Liquid oil removing, float, it mainly shows as Produced Liquid and enters oil removing pot oil-containing and suspension content far above common oil removing pot design objective, the most a large amount of silt particles and float are enriched with at tank deck, i.e. influence whether the normal work of oil removing pot in short time, cause processing system to paralyse.
