Abstract

The invention belongs to the field of viscosity reduction, particularly relates to a multifunctional viscosity reducer and a preparation method thereof. The invention aims to overcome the problems of low viscosity reduction rate, fixed viscosity reduction rate and difficulty in cracking in the prior art. According to a scheme in the invention, the multifunctional viscosity reducer comprises the following components in parts by mass: 20 parts of water, 16 to 20 parts of a biological enzyme, 6 to 10 parts of nonylphenol polyoxyethylene ether, 6 to 10 parts of N-heterocyclic carbene iron, 6 to 10 parts of ethanol, 2 to 6 parts of a modified mixture, 2 to 5 parts of an additive and 2 to 5 parts of an auxiliary agent, wherein the modified mixture comprises modified sodium carbonate and surface soil of saline-alkali land. According to the invention, the multifunctional viscosity reducer can effectively decompose heavy oil and reduce the viscosity of heavy oil, is improved in viscosity reduction rate, can effectively improve the viscosity reduction rate along with the increase of temperature, the guarantees viscosity reduction effect on the heavy oil, and can effectively crack heavy components in the heavy oil and crack most of the heavy components in the heavy oil into light components.

Description

technical field [0001] The invention relates to the technical field of viscosity reduction, in particular to a multifunctional viscosity reduction agent and a preparation method. Background technique [0002] Heavy oil has the characteristics of high viscosity, high freezing point, and poor fluidity in the formation. In order to ensure the normal production, a viscosity reducer is needed. The patent application number CN201410553381.6 discloses a heavy oil emulsification viscosity reducer. This The invented thick oil emulsification viscosity reducer has good viscosity reduction effect on heavy oil, and the viscosity reducer has strong salt resistance, low use concentration, low cost, no need to add alkali when used, and is more suitable for alkali-sensitive formations. [0003] However, this heavy oil emulsification viscosity reducer also has some problems. For example, the viscosity reduction effect is limited, it can only be effective for a small part of heavy oil, the vis...
