Background technology
Oil field after drilling, will produce many rejected well drilling liquids.Rejected well drilling liquid is mainly by heavy weight additive, clay, chemistry
Multiphase colloid-suspended substance the system for managing the compositions such as agent, water, oil and drilling cuttings, containing there are many ingredients for leading to environmental pollution.
Oil field large dosage water plugging and profile controlling is mostly stifled with polymer gel, lignin, dry ash, flyash, three-phase froth, tannin extract etc.
It is of high cost based on agent.Under individual well large dosage use condition, ratio for input and output is low, it is difficult to promote and apply so that many to need to block up
The service shaft of water profile control cannot be administered effectively, and the Efficient Development of oil reservoir is hindered.
Utility model content
The purpose of this utility model is that devising a kind of solid controlling system being used for water plugging and profile controlling using discarded slurry, pass through
The system realize rejected well drilling liquid carry out it is quenched after be used as profile-controlling and plugging agent, to reduce asking for waste discharge and environmental pollution
Topic.
To achieve the above object, the technical solution adopted in the utility model is that a kind of application discarded slurry is used for water plugging and profile controlling

Centrifuge 15, water treatment unit 16 and the second centrifuge 17.
Rejected well drilling liquid is connect with splicing funnel 1, and the outside of splicing funnel 1 is equipped with vibrating screen 2, splicing funnel 1 and spiral
One end of conveyer 4 connects, and the other end of auger conveyor 4 is connect with dry sieve 7；Dry sieve 7 and one end of drying chamber 8 connect
It connects, the other end of drying chamber 8 and the connection of the second sand pump 9；Second sand pump 9 and gel breaker 11 by static mixer 10 and first from
Scheming 15 connects, and demulsifier 14 is connect with the first centrifuge 15.
Drying chamber 8 is connect by diaphragm pump 12 with slurry tank 13, and slurry tank 13 is connect with the second centrifuge 17, the second centrifuge 17
By the first sand pump 3 with except sand warehouse 5 and except hopper dredger 6 is connect；Except hopper dredger 6 is connect with discarded slurry.
Discarded slurry is pumped by the first sand pump 3 in the second centrifuge 17 after removing hopper dredger 6 and being handled except sand warehouse 5, the
By treated, discarded slurry slurries import in slurry tank 13 two centrifuges 17.
Auger conveyor 4 transports the rejected well drilling liquid in splicing funnel 1 into drying chamber 8 by dry sieve 7, diaphragm pump
The slurries starched in tank 13 are mixed the second sand pump of merga pass 9 by 12 with the rejected well drilling liquid by dry sieve 7 to be exported, derived mixing
Liquid is mixed with gel breaker 11, subsequently into the first centrifuge 15, then is directed into water treatment unit 16 after being mixed with demulsifier 14.
Compared with prior art, the utility model has the following effects that.
The discarded slurry water blockoff solid control equipment of the utility model may be implemented to be used as profile control after rejected well drilling liquid progress is quenched
Water shutoff agent has preferable application prospect.Because drilling fluid not only has good salt resistance, high temperature resistance, anti-shear performance, it is convenient for
Large dosage of profile control squeezing, and be the blocking agent that a kind of price is low, profile control effect is good.Waste injection stratum is also solved simultaneously
Problem is arranged outside waste, reduces environmental pollution and solidification expense.
