Example Embodiment

[0020] Examples:

[0021] The invention relates to a method for determining the content of a gel breaker applied in the petroleum industry, which comprises the following steps:

[0022] (a) Prepare the breaker to be tested for use;

[0023] (b) Breaking the prepared gel breaker;

[0024] (c) Take the broken fracturing fluid for use;

[0025] (d) Centrifuge the fracturing fluid;

[0026] (e) Take out the solid and dry it;

[0027] (f) Analyze the ratio between the mass obtained by drying and the volume of the formulated fracturing fluid to obtain the breaker content.

[0028] In the step (d), the fracturing fluid is centrifuged by a high-speed centrifuge.

[0029] In the step (e), the solid is dried by a dryer.

[0030] In the step (e), the drying temperature is 120°C.

Abstract

The invention discloses a method for determining the content of a gel breaker applied in the petroleum industry. The method comprises the following steps: 1, preparing a gel breaker for measurement for later use; 2, carrying out gel breaking of the prepared gel breaker; 3, taking a gel-broken fracturing fluid for later use; 4, centrifuging the fracturing fluid; 5, taking out the above obtained solid, and drying; and 6, analyzing a ratio of the mass of the obtained dried solid to the volume of the above formula fracturing fluid to obtain the content of the gel breaker. The method has the advantages of rapid determination of the content of the gel breaker, high test precision, simple test steps, and substantial reduction of the test cost.

Description

technical field [0001] The invention relates to a test method, in particular to a method for determining the content of a gel breaker used in the petroleum industry. Background technique [0002] Commonly used oxidative breakers include potassium persulfate and ammonium persulfate. Since the activity of the oxidizing agent is related to the temperature, generally when the formation temperature is lower than 49°C, the reaction speed is very slow, and an activator needs to be added. [0003] Oxidative breakers have many defects such as: ①It reacts rapidly with fracturing fluid at high temperature, causing the fracturing fluid to degrade in advance and lose the ability to transport proppant, even leading to failure of fracturing construction; ②It is a non-specific reactant , can react with any reactants encountered such as pipes, formation matrix and hydrocarbons, etc., and generate pollutants that are incompatible with the formation, causing formation damage; ③The oxidative b...
