Abstract
The invention provides a dilatation-retarding modified modifying and flooding agent for oil extraction and a preparation method thereof. The dilatation-retarding modified modifying and flooding agent comprises two components, namely a modifying and flooding agent A and a modifying and flooding agent B, wherein the modifying and flooding agent B can form a layer of protective waterproof film in a solution of the modifying and flooding agent A, so that the modifying and flooding agent does not expand basically in the injection process; and the modifying and flooding agent can quickly expand only when a protective film formed on the particle surface is destroyed under the stratum condition after the modifying and flooding agent enters a target layer, a high-permeability stripe and a hole, so as to effectively block off. The dilatation-retarding modified modifying and flooding agent just can expand in the stratum, so that water absorption puffing of the swellable modifying and flooding agent in the injection process and chopping in the stratum are overcome. In addition, the dilatation-retarding modified modifying and flooding agent also has the advantages of high strength of water shutoff profile control particles in an oilfield and low water absorption expansion rate.
Description
Technical field:
The present invention relates to petroleum industry chemical article field, particularly relate to a kind of oil recovery with slow swollen modification adjusting driving agnet and preparation method thereof.
Background technology:
China's field produces major part adopts displacement of reservoir oil by filling water mode, and existing maturing field water ratio majority is more than 90%, and production rate decline is more and more faster.Water plugging and profiling technology is a kind of effective means improved water flooding effect, realize oil reservoir stable yields.Volume expansion grain is the product grown up in recent years, and the profile control for well carrys out improving ecology effect, improves floood conformance volume, reduces Water Content in Oil amount, improves recovery ratio.But it is very fast that this kind of water plugging and profile controlling particle there will be particulate water absorbent speed of expansion when being used for deep profile correction, just start to expand do not pump into well casing in dosing pond, ground before, not easily be delivered to darker stratum, in addition, because water blockoff granule strength is lower, premature inflation in addition, strength degradation is obvious, make pumping in process, be easy to fragmentation by the shearing volume expansion grain on screen casing and stratum, thus lose water plugging and profile controlling effect.
Summary of the invention:
In order to overcome the defect of prior art; the invention provides a kind of oil recovery and use slow swollen modification adjusting driving agnet and preparation method thereof; slow swollen modification adjusting driving agnet is made up of A agent, B agent two kinds of components; adjusting driving agnet B, in the solution of adjusting driving agnet A, can form one deck protection waterproof membrane, cause adjusting driving agnet in injection process substantially not expand; only after entering zone of interest, high permeable strip, hole; under formation conditions, the protective film that particle top layer is formed is destroyed, undergoes rapid expansion thus carry out effective shutoff.Slow swollen modification adjusting driving agnet is owing to just expanding on stratum, and therefore overcome volume expansion type adjusting driving agnet and absorb water expanded in injection process, the defect of easily shredding on stratum, in addition, the intensity that the present invention also has Water in Water Shutoff in Oil Field profile control particle is high, the advantage that water-swelling speed is slow.
Technical scheme of the present invention is, provide a kind of and recover the oil with slow swollen modification adjusting driving agnet and preparation method thereof, the described oil recovery moiety of slow swollen modification adjusting driving agnet, by mass percentage, comprising:
