Abstract
The present invention provides a kind of profile control agents prepared with offshore drilling platform discarded slurry, include the components of following parts by weight, 55~65 parts of discarded slurry；35~42 parts of industrial water；0.1~0.5 part of anionic polyacrylamide；0.1~0.5 part of phenolic resin crosslinking agent；0.1~0.5 part of stabilizer.Profile control agent of the present invention based on the discarded slurry generated in drilling process, prepares the profile control agent needed for profile control technology and carries out profile control to water injection well and block the demand of the techniques such as stratum.A kind of more reliable method is provided to the harmless treatment requirement of discarded slurry for drilling platforms.
Description
Technical field
The invention belongs to oil development technical field, prepared more particularly, to a kind of with offshore drilling platform discarded slurry
Profile control agent.
Background technology
It is discarded to what is generated in drilling process in oil drilling exploitation as the requirement to environmental protection is higher and higher
Mud requirement carries out harmless treatment.Existing processing method by slurry transportation to the treatment plant specified or will generally be handled
Equipment moves construction site treatment in situ to.
Construction space is narrow and small for offshore platform, is not suitable for the installation of gadget and puts.Using Shipping
Process is added, security risk is brought to environmental protection and construction.Meanwhile the water injection well of drilling platforms need to there is also certain profile control
It asks.For this purpose, with reference to two kinds of above-mentioned difficulties, it is necessary to provide it is a kind of by discarded slurry be configured to profile control agent carry out profile control technology apply
The method of work.
The content of the invention
In view of this, the present invention is directed to propose it is a kind of with offshore drilling platform discarded slurry prepare profile control agent, to overcome
The deficiencies in the prior art solve the process problem of drilling platforms drilling well discarded slurry and meet need of the water injection well to profile control technology
It asks.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of profile control agent prepared with offshore drilling platform discarded slurry includes the component of following parts by weight, waste sludge
55~65 parts of slurry；35~42 parts of industrial water；0.1~0.5 part of anionic polyacrylamide；Phenolic resin crosslinking agent 0.1~0.5
Part；0.1~0.5 part of stabilizer.
Preferably, the component of following parts by weight, 60 parts of discarded slurry are included；38.5 parts of industrial water；Anion poly- third
0.1~0.5 part of acrylamide；0.1~0.5 part of phenolic resin crosslinking agent；0.1~0.5 part of stabilizer.
Preferably, the water content of the discarded slurry is 50~60%.
Preferably, the molecular weight of the anionic polyacrylamide is 1000~12,000,000.
Preferably, the stabilizer is hydroquinone and the mixture of aluminate coupling agent.
Preferably, the weight ratio of hydroquinone and aluminate coupling agent is 1:1~3:1.
Preferably, the weight ratio of hydroquinone and aluminate coupling agent is 2:1.
The present invention also provides a kind of profile control agent as described above prepared with offshore drilling platform discarded slurry in water injection well
Carry out the application in profile control and closure stratum.
Compared with the prior art, it is of the present invention with offshore drilling platform discarded slurry prepare profile control agent, have with
Lower advantage：
Profile control agent of the present invention based on the discarded slurry generated in drilling process, is prepared needed for profile control technology
Profile control agent profile control is carried out to water injection well and blocks the demand of the techniques such as stratum.It is drilling platforms to the innoxious place of discarded slurry
Reason requirement provides a kind of more reliable method.
