Description
Technical field
The utility model relates to a kind of super fine composite powders to be used for offshore oilfield Profile Control in Injection Well system, belong to offshore oilfield
Technical field of tertiary oil recovery.
Background technique
Offshore oilfield is because of reservoir characteristics good (major oil reservoir permeability > 2000md, porosity > 25%, core intersection >
10m), exploitation generally adopts injection technology using strong.It is connected to because exploiting oil reservoir between oil-water well, adopts injection by force and cause to inject water edge
Oil well is scurried into big channel, is caused water drive to involve and is become smaller, and harvesting is low, and well water is substantially increased, and declines oil recovery efficiency.Thus must
It must be in well end profile control, to block the big channel of water flow.The method blocked at present mainly use high polymer polyacrylamide gel into
Row profile control, land different with offshore oilfield well-completing process process, wherein onshore oil field can be sealed with 1-4cm volume expansion type blocking agent
It is stifled.
But due to high polymer polyacrylamide gel non-refractory (85 DEG C of <), and due to two valences cation in water flooding
Influence to high polymer polyacrylamide gel, validity period only have or so half a year, and limited to the plugging effect of big access,
Super fine composite powder (the D that organic and inorganic phase combines is developed thus503-40 μm) bridge formation profile control blocking technology.This technology exists
The main problem encountered in is as follows:
1, when super fine composite powder manually pours into agitator tank, wind causes entire offshore production platform dusty, to work
The body for making personnel is extremely harmful.
2, marine humidity is big, and super fine composite powder is easy dampness, has into bulk after opening packaging, can not apply.
3, quantitative control is difficult in practical process.
4, the operation large labor intensity of worker.
Summary of the invention
The purpose of this utility model is to propose that a kind of super fine composite powder is used for offshore oilfield Profile Control in Injection Well system, is passed through
The system enables super fine composite powder quantitatively can smoothly enter into agitator tank, feeds profile control high head injection pump, reaches design profile control and wants
It asks.
The utility model proposes super fine composite powder be used for offshore oilfield Profile Control in Injection Well system, including the own system of platform
Nitrogen machine, pneumatically takes powder machine, deduster, mixing agitator and high head injection pump at super fine composite powder holding vessel；The platform system
Nitrogen machine, super fine composite powder holding vessel, pneumatically taking powder machine, deduster, mixing agitator and high head injection pump passes sequentially through pipeline
It is connected, the outlet of the high head injection pump is connected with oil well；Entrance installation in the super fine composite powder holding vessel
There is Pneumatic creeping pump.
The utility model proposes super fine composite powder be used for offshore oilfield Profile Control in Injection Well system, advantage is as follows:
1, the utility model proposes offshore oilfield Profile Control in Injection Well system in, super fine composite powder using steel seal
Potting fills, not moisture-sensitive.
2, it in the offshore oilfield Profile Control in Injection Well system of the utility model, can be equipped in sealing potting multiple pneumatic
Peristaltic pump is smoothly flowed out from storage tank convenient for super fine composite powder.
3, in the offshore oilfield Profile Control in Injection Well system of the utility model, it is pneumatic carry super fine composite powder from storage tank to
Agitator tank reduces the labor intensity of operator.
4, in the offshore oilfield Profile Control in Injection Well system of the utility model, air pressure and time can be set in advance, it is real
Super fine composite powder is now quantitatively adding to agitator tank, keeps operating procedure stably and controllable.
5, in the offshore oilfield Profile Control in Injection Well system of the utility model, dust guard is increased, solves wind dust
Problem is flown upward, the working environment of staff is substantially improved.
6, the utility model proposes offshore oilfield Profile Control in Injection Well system in, equipment is simple, easy to operate, safely may be used
It leans on.
Detailed description of the invention
Fig. 1 is that the super fine composite powder of this practical proposition is used for the structural representation of offshore oilfield Profile Control in Injection Well system
Figure.
In Fig. 1,1 is platform nitrogen making machine, and 2 be super fine composite powder holding vessel, and 2.1 be Pneumatic creeping pump (mounted in ultra-fine multiple
Close blanking position in powder storage tank), 3 be pneumatically to take powder machine, and 4 be deduster, and 5 be mixing agitator, and 6 be high head injection pump.
Specific embodiment
The utility model proposes super fine composite powder be used for offshore oilfield Profile Control in Injection Well system, structure such as Fig. 1 institute
Show, including platform nitrogen making machine 1, super fine composite powder holding vessel 2, pneumatically takes powder machine 3, deduster 4, mixing agitator 5 and high pressure
Injection pump 6.Platform nitrogen making machine 1, pneumatically takes powder machine 3, deduster 4, mixing agitator 5 and high pressure at super fine composite powder holding vessel 2
