Abstract
The invention belongs to a method for preparing a profile adjusting and water plugging agent from slurry obtained after treatment on waste water of oil fields, comprising the following steps of: adding acrylamide and sodium acrylate monomers in waste polymer gel generated in the exploitation of oil fields for copolymerization crosslinking to synthesize a swelled oil field profile adjusting agent for adjusting the deep profile of a large-oil path oil deposit during the exploitation of the oil field. The obtained profile adjusting and water plugging agent for oil fields is applied to high-water content zones during the exploitation of oil fields and is a swelled oil field profile adjusting agent for adjusting the deep profile of the large-oil path oil deposit. The adsorption time of the product for NaCl saltwater with the weight concentration of 0.9% is 35 g/g to 60 g/g.
Description
Technical field
The present invention utilizes oil field waste to handle the method for back mud for the feedstock production profile-controlling and plugging agent.
Background technology
The oilfield waste gel be in oilfield exploitation is produced after treatment, the waste polymer gel of generation, this gel major ingredient are little crosslinked or crosslinked polyacrylamide gels bodies partly.Contain certain crude oil, metal ion and some mineral substance.Generally by treatment processs such as landfills, not only environmental pollution is very big, and the waste resource.Environment had both been protected in the how innoxious and comprehensive utilization of resources with waste, increased waste recycle again, more and more was subjected to people's attention.
Chinese patent CN1781860 " a kind of synthetic method of utilizing oil exploitation sludge to prepare volume expansion type granular profile control agent " has prepared a kind of granular profile control agent with the oil exploitation sludge of discarding landfill originally.The processing more complicated of this its mud of patent and cause dust pollution easily 2 times, the polymkeric substance synthesis condition has limited the additive capacity of greasy filth.
Chinese patent CN1085590 " a kind of water-pluging Polymer amendment " is characterized in that organosilane and yin, yang, non-ionic monomer form a kind of tridimensional network high molecular polymer in the aqueous solution, is the amendment of using always.
Chinese patent CN1796484 " a kind of preparation method of crosslinking copolymerization type particulate state amendment ", this method adopts acrylamide and two kinds of organic monomers of vinylformic acid as host, prepares crosslinking copolymerization type particulate state amendment to add wilkinite or kaolin as toughener.
The raw material that present preparation profile-controlling and plugging agent uses is organic or inorganic industrial chemicals, cost height.
Summary of the invention
The invention provides the present invention is to utilize oil field waste to handle the method for back mud for the feedstock production profile-controlling and plugging agent.Main purpose is that the waste resource in recovering the oil is carried out harmless treatment, avoids the landfill of refuse and discardedly causes environmental pollution, reaches that waste resource is innoxious, the making full use of of resource utilization.
