| titleOfInvention | A kind of organic zirconium crosslinker and preparation method thereof |
| abstract | The present invention relates to a kind of preparation method and application of the New Organo-Zirconium crosslinking agent for deep profile controlling transfer drive, belongs to oilfield chemistry and improves oil recovery factor technical field.It is to be synthesized with eight water oxygen zirconium chlorides, citric acid and ethylenediamine etc. for base stock, can realize effective control of delay crosslinking time and viscosity, and can be with salinity 40000mgL ‑1 Hereinafter, 0-600mgL of calcium ions and magnesium ions content ‑1 Various sewage are with poly-, 35 DEG C -70 DEG C oil reservoirs of Applicable temperature.In deep profile controlling transfer drive system, clear water can be replaced with sewage with poly-, as a kind of function admirable and the green non-pollution crosslinking agent harmless to reservoir, improves oil recovery factor.Solve that conventional cross-linking agent ground adaptability is poor, and salt-resistance is poor, be only suitable for clear water compatibility, pollution weight, it is big to reservoir damage the problems such as.Site test results of the present invention show that the cross linker system can be with live sewage compatibility, and plastic effect is preferable, beneficial to environmental protection. |
