Description
Technical field
The present invention relates to oilfield prospecting developing underground work technical field, in particular to a kind of environment-friendly type coiled tubing subtracts
Resist.
Background technique
In underground work field, coiled tubing construction task specifically include that coiled tubing cutting during well workover, salvage,
The construction operations such as sand washing and de-plugging；With coiled tubing dragging acidification, conveying bridge plug and perforating gun and brill plug during reservoir reconstruction
Operation.Wherein, for high angle hole or with the horizontal well of long horizontal sections, coiled tubing construction is by horizontal section length, wellbore rail
Mark, horizontal segment hole angle etc. influence, and coiled tubing tripping in " locking " phenomenon often occur.That is: during coiled tubing enters well,
Resistance is generated since the buckling of coiled tubing itself makes it rub in horizontal segment progradation with steel internal surface of sleeve pipe, resistance reaches
Just occur to a certain extent self-locking, i.e., no matter applying much thrust to coiled tubing can not all promote.
For this problem, mainly subtracted at present using drafting tool, hydroscillator and metal in coiled tubing construction
Resist is solved, i.e., reduces the coefficient of friction between coiled tubing outer wall and internal surface of sleeve pipe by using metal drag reducer to keep away
The problem for exempting to occur self-locking too early.The metal drag reducer being commonly used in coiled tubing work progress at present is emulsion form poly- third
Acrylamide drag reducer forms the material of the agent although this slippery water shows more excellent lubricant effect with drag reducer
Expect that big multipair environment has pollution, returning liquid after draining into ground must be handled.Publication CN105255572A is mentioned
For a kind of coiled tubing metal drag reducer, using water as decentralized medium, remaining component is by mass percentage are as follows: basic mine
Object oil 82-90%, oil soluble emulsifying agent 4-10%, temperature stability agent 1-2%, metal inhibitor 2-5% and defoaming agent 0.1-
1%.The coefficient of friction resistance of metal tube intercolumniation can greatly be just reduced using the low concentration aqueous solution of the system, and then is reduced continuous
The self-locking degree of oil pipe increases coiled tubing in the development length of horizontal segment；However the metal drag reducer functionally has one
Determine defect, especially oil-gas Layer to have already turned on and need the case where carrying out coiled tubing construction, it is as continuous in used after pressing crack construction
When oil pipe bores plug, in this case, stratum has been exposed through, and easily makes its hair when coiled tubing drag reducer is contacted with stratum clay
Raw expansion and migration phenomenon, influence stratum permeability energy and pollute injury to stratum, further influence oil and gas production.
Summary of the invention
The wide pH scope of application, the high environmental protection for preventing swollen performance and significant resistance reducing performance are had both the object of the present invention is to provide a kind of
Type coiled tubing drag reducer.
For this purpose, technical solution of the present invention is as follows:
A kind of environment-friendly type coiled tubing drag reducer, including based on mass fraction 5~15% turkey red oil, 15~40%
Nonionic surfactant, 10~20% small molecule dihydric alcohol, 10~20% clay stabilizer and surplus water.
It is preferred that the nonionic surfactant is Tweens surfactant or isomerous tridecanol polyethylene glycol oxide ether.
It is preferred that the small molecule dihydric alcohol is ethylene glycol, propylene glycol or butanediol.
It is preferred that the clay stabilizer is the benzyl quaternary ammonium salt reacted using triethanolamine and benzyl chloride.
It is preferred that the benzyl quaternary ammonium salt is anti-by the benzyl chloride of 270~300 parts by weight of triethanolamine of 330~360 parts by weight
It should obtain.
It is preferred that the benzyl quaternary ammonium salt the preparation method comprises the following steps: triethanolamine is dissolved in 0.15~0.25 times of triethanolamine
Water in, and be warming up to 50~70 DEG C, under stirring, benzyl chloride be added dropwise, 75~110 DEG C are warming up to after being added dropwise,
The reaction was continued 4~8h.
The environment-friendly type coiled tubing drag reducer preparation method is simple, and preparation step is as follows: under the conditions of high-speed stirred, in water
Middle addition nonionic surfactant is stirred to turkey red oil is added after mixing, continues stirring to being uniformly mixed, thereto
Be added small molecule dihydric alcohol and clay stabilizer, it is to be mixed to after mixing to get arriving environment-friendly type coiled tubing drag reducer.
It is preferred that in the preparation process of environment-friendly type coiled tubing drag reducer, mixing speed 10000r/min.
The environment-friendly type coiled tubing drag reducer is applied to all kinds of underground works such as fracturing fluid, acid solution, perforating fluid and workover fluid
Dosage in liquid is generally 0.1~2wt.%.
Compared with prior art, the environment-friendly type coiled tubing drag reducer be one kind have both wide pH application environment, high temperature tolerance,
Height prevents swollen performance and significantly reduces the environment-friendly type coiled tubing drag reducer of the coefficient of friction performance between metal material, and it is suitable for pH
Value between 1~14, salinity be no more than the various underground work liquid of 30000mg/L, heatproof temperature is up to 150 DEG C, prevents swollen
Rate > 83% is prevented swollen 1 month performance duration >, while the addition of the drag reducer can make the coefficient of friction between metal material
It is reduced to 0.12 from 0.74, is suitable for use as the addition of all kinds of underground work liquid such as preparing fracturing fluid, acid solution, perforating fluid and workover fluid
Agent.
