Abstract

The invention relates to the technical field of profile-modifying and plugging agents for oil extraction and crosslinking agents thereof, in particular to a compound multivalent metallic ion crosslinking agent, a high-strength profile-modifying and plugging agent, and a production method and a use method thereof. The crosslinking agent comprises chromium citrate, zirconium lactate, aluminum citrate, organic boron, organic titanium, bisphenol A, resorcinol, methenamine and the balance of water. The invention is characterized in that the compound multivalent metallic ion crosslinking agent and the high-strength profile-modifying and plugging agent have the advantages of low cost, simple preparation method and high efficiency. The high-strength profile-modifying and plugging agent formed by the compound multivalent metallic ion crosslinking agent and polymers is suitable for plugging water for high water-cut oil layers and has strong adaptability. The high-strength profile-modifying and plugging agent can plug water in the recycle oil layer by utilizing industrial water and oil field sewage so as to effectively enhance the strength and the temperature resistance of the profile-modifying and plugging agent. The profile-modifying and plugging agent can resist a pressure of 3-15 MPa and resist a temperature of 30-150 DEG C.

Description

technical field [0001] The invention relates to the technical field of a plugging regulator and a crosslinking agent used in petroleum exploitation, and relates to a composite polyvalent metal ion crosslinking agent, a high-strength plugging regulator, a production method and a use method thereof. Background technique [0002] At present, the cross-linking agents used in oilfields include sodium dichromate, chromium citrate, zirconium lactate, aluminum citrate, etc., which have poor adaptability, especially for reinjection of oilfield sewage. According to the industry {SY / T5277 -2000} standard is measured on an indoor dynamic device to obtain water shutoff in high water-cut oil layers, with a pressure resistance of 0.53MPa. to 3.5MPa. and a temperature resistance of 20°C to 50°C. This fully demonstrates that a single cross-linking agent can no longer meet the requirements of oil field development. Contents of the invention [0003] The invention provides a composite polyv...
