Description

the displacement of reservoir oil is applied with in poly-table pack thing and tertiary oil recovery thereof
Technical field
The present invention relates in the poly-table pack thing of the displacement of reservoir oil, preparation method and tertiary oil recovery thereof and apply.
Background technology
How China's main oilfield, through once with after secondary recovery entering high water-cut stage, improves oil recovery factor, develops remaining reserves to greatest extent, and tertiary oil recovery technology has played very important effect in guarantee oilfield stable production high yield.In tertiary oil recovery new technology, chemical combined flooding remains one of very promising method of tool.
After oil field enters high water-cut stage, surplus oil with discontinuous oil film by trap in the hole of reservoir rocks, two the main power acted on oil droplet be viscous from and capillary force.If use suitable surfactant system, reduce the interfacial tension between profit, just decrease oil droplet when irreducible oil moves and be out of shape the resistance brought, thus improve oil recovery factor.
In recent years, it is found that betaine type surfactivity had good table, interfacial activity, comparatively low interfacial tension can be formed at water-oil interface.Meanwhile, due to its Stability Analysis of Structures, there is huge legendary turtle cooperation use to metal ion, thus can attempt the oil reservoir displacement of reservoir oil for high salinity, comparatively high temps.In addition, another feature of betaine type amphoteric surfactant is its performance to be affected not quite by the pH of salinity and medium, thus can in salinity higher or within the scope of pH widely for combination flooding, thus to cause great concern.Have the betaine type amphoteric surfactant of interface performance and rheological, be expected to replace the alkali in ternary composite driving formula, under rational formula system, finally realize binary displacement system, the chemical flooding for oil field opens up new approach.
