| titleOfInvention | Application of a kind of deep regulation and displacement gel |
| abstract | The invention discloses the application of a novel deep regulating and driving gel. The deep control and displacement gel deep control and displacement method provided by the present invention includes the following steps: injecting the mixed aqueous solution of ketone polymer and hydrazide polymer into the stratum of the oil reservoir to carry out polymer flooding; Water flooding; the mixed aqueous solution is prepared by using mineralized water; the structural formula of the ketone polymer is shown in formula I, and the structural formula of the hydrazide polymer is shown in formula II. Based on the dynamic hydrazone bond, the present invention uses ketone polymers and hydrazide polymers as reactive precursors to obtain a deep profile control and drive gel system, which can meet the requirements of deep profile control agents for easy injection into the formation, and in the formation The deep part requires the formation of high-permeability large pores; and the acylhydrazone bond has the property of reversible formation-breakage, and the bond breakage can be realized by simply adjusting the pH, avoiding the risk of excessive cross-linking reaction blocking the formation. And the development of deep profile control has brought new breakthroughs. |
