Method for measuring solid content of hydroxamic acid type polyacrylamide

Abstract

The invention discloses a method for measuring the solid content of hydroxamic acid type polyacrylamide. The method comprises the steps of: weighing Mg of a polymer test sample; drying under the condition of a certain temperature; taking out a weighing bottle and cooling to room temperature, wherein the weight is weighed to be m; calculating the solid content S according to M and m; and the like. The method disclosed by the invention can be used for rapidly measuring the solid content of the hydroxamic acid type polyacrylamide, has high measurement precision and simple measurement steps, is beneficial to reduction of the measurement cost and provides good data support for use of the hydroxamic acid type polyacrylamide.

Description

technical field

[0001] The invention relates to a method for measuring the solid content of hydroxamic acid type polyacrylamide. Background technique

[0002] Facing the current situation of my country's environmental protection and the pressure brought by the international green fortress, it is very urgent to develop and research oilfield environmental protection technology in my country and solve the major environmental protection problems that plague my country's social and economic development.

[0003] In the process of oil and gas exploration and development, oil and gas companies have adopted a large number of measures such as drilling and other oil and gas wells to put into production and increase production, resulting in a large amount of drilling sewage. During drilling, each well produces 400-500m of drilling sewage 3 , waste drilling fluid 500~700m 3 . At present, solving the pollution problem of sewage has become one of the important research topics of environ...
