Abstract
The invention relates to a modification method for ZG gum for the production in an oil field, which comprises the following steps of: dispersing ZG gum powder into water in a container; adding a modifier into the container with stirring; then stirring and heating reactants in the container; adding sodium hydroxide or potassium hydroxide solution into a reaction system in the reaction process; regulating a pH value and keeping the pH value in the range of 7 to 8; after the reaction is finished, cooling to the room temperature to obtain colorless water glue solution, i.e. ZG gum modifier glue solution, in the container; and evaporating out water in the colorless glue solution in the container to obtain light gray solids, i.e. a ZG gum modifier. When the ZG gum modifier is applied, the ZG gum modifier is dissolved in water to be prepared or diluted into solution with the mass concentration of 0.1 to 5 percent; the obtained solution is added into low solid or high solid water base drilling fluid; and the depressing filter loss performance and the increasing viscosity of the ZG gum modifier are measured by adopting the API (American Petroleum Institute) standard so as to obtain a measurement result that after the ZG gum modifier is applied, the filter loss can be reduced by 30 to 60 percent and the viscosity can be improved by 20 to 200 percent.
Description
Technical field
