Description
Technical field
The present invention relates to a kind of inorganic agent in oil extraction in oil field technical field, especially a kind of PS lignin gel-type profile control agent
And preparation method thereof.
Background technology
Most of current oil field uses waterflooding extraction, due to washing away for injection water, makes the inhomogeneity of oil reservoir over time
Passage and aggravate.The heterogeneity of oil reservoir, make injection water usually be absorbed by high permeability zone, in order in playing, less permeable layer
Effect, improves the intake profile for being related to coefficient, must just adjusting Deplug of injection water, i.e. profile control namely seals profile control agent
Stifled high permeability zone, reduces the water absorbing capacity of high permeability zone, so that hydrologic(al) budget injection profile.The profile control agent of application is due to first at present
Beginning viscosity it is high and cause profile control agent enter non-profile control target zone, and then to non-closure site pollute；Gel strength is low, colloid is unstable
Fixed, the easy syneresis of colloid, so as to cause the term of validity of profile control short, closure efficiency is low, and profile control effect is poor.
The content of the invention
The invention reside in overcoming, existing profile control agent initial viscosity present in background technology is high, the profile control term of validity is short, closure
Efficiency is low to cause the problem of profile control effect difference, and provides a kind of PS lignin gel-type profile control agent.The PS lignin gel-type is adjusted
Agent is cutd open, the profile control term of validity is long, it is good to block efficiency high, profile control effect.Present invention also offers a kind of PS lignin gel-type profile control
The preparation method of agent.
The present invention solves its problem can be reached by following technical solution：The PS lignin gel-type profile control agents, its group
Divide and match as follows by weight percentage：High molecular polymer 0.5-1.5%, gel 1-10%, deflocculant 0.2-2.0%,
Reducing agent 0.2-2.0%, intercalating agent 0.2-0.6%, retarder 0-1.0%, crosslinking agent 0.5-1.5%, remaining be water.Described percentage
Than being counted as 100% with the gross weight of lignin gel-type profile control agent.
The high molecular polymer molecular weight is 1200-1600 ten thousand, the polyacrylamide of degree of hydrolysis 20-30%；The gel
Agent is calcium lignosulfonate, and deflocculant is thiocarbamide；Crosslinking agent is sodium dichromate；Reducing agent is anhydrous sodium sulfite；Intercalating agent
It is tetrasodium ethylenediamine tetraacetate；Retarder is sodium citrate.
The present invention also provides a kind of preparation method of PS lignin gel-type profile control agent, adds water, again in a reservoir first
Sequentially add under the normal temperature and pressure of gel, deflocculant, reducing agent, intercalating agent after circulation stirring half an hour, then slowly spread
Enter high molecular polymer, circulation stirring 2 hours is placed 8 hours, is lignin gel-type profile control agent A agent；Simultaneously by crosslinking agent with
Water presses 1：1 ratio is dissolved completely in another container, is lignin gel-type profile control agent B agent；A agent is added into slow setting before injection
, be added thereto for B agent again then by agent, stirs.Product Applicable temperature is 30-65 DEG C.
PS lignin gel-type profile control agents are certain by polyacrylamide (PAM) and calcium lignosulfonate (Ca-LS)
Under the conditions of by the modified new chemical agent formed with grafting as gel-forming substance.In the presence of heat and crosslinking agent, polypropylene
There is condensation reaction in acid amides and calcium lignosulfonate, generate a kind of new gel-forming substance PAM-Ca-LS (being abbreviated as PS).
It is of the invention to be had the advantages that compared with above-mentioned background technology：The PS lignin gel-type profile control agents,
Ground viscosity is small, and gel time is adjustable, and gel strength is big, product plastic stabilization, is difficult syneresis, the water plugging and profile controlling term of validity
It is long, block efficiency high.Behind product injection stratum, using three big mechanism such as physics person blocking, power trapping and absorption, preferably seal
Stifled injectivity index interval high, realizes adjustment intake profile, the purpose of Efficient Development.Product cost is low, and construction technology is easy, can
Pump is strong.
