Abstract

The present invention relates to a method for preparing alcohol-based fracturing fluid, comprising: step S1, injecting a thickener into a preparation chamber through a first feeding port, and swelling with water in the preparation chamber; and step S2, passing through a first preset time, alternating The coupling agent passes through the second feed port, the foaming agent passes through the third feed port, the compounding agent passes through the fourth feed port, and the foam stabilizer is injected into the preparation chamber through the fifth feed port to stir and mix with the swollen thickener Alcohol-based fracturing fluid is formed; step S3, the alcohol-based fracturing fluid is injected into the detection chamber through the first pipeline, and the central control unit controls the detection chamber to be inverted several times. After the second preset time, the central control unit injects the alcohol-based fracturing fluid through The second pipeline is discharged, and the central control unit obtains the stability of the alcohol-based fracturing fluid, and determines that the alcohol-based fracturing fluid with qualified stability will be produced. In the present invention, a central control unit is set to adjust the parameters of each component so that the stability of the produced alcohol-based fracturing fluid meets the preset standard.

Description

technical field [0001] The invention relates to the field of fracturing fluids, in particular to a method for preparing alcohol-based fracturing fluids. Background technique [0002] Oil and gas resources are important strategic materials for national survival and security, and are also an important component of national economic construction and life. In recent years, with the adjustment of the national energy structure, water-sensitive reservoirs and tight reservoirs, which are important components of unconventional oil and gas with huge reserves and great impact on environmental protection, have gradually become the focus of exploration and development of unconventional oil and gas resources in my country. One of the key objects. At present, water-based fracturing fluids are mainly used in the exploitation of unconventional oil and gas reservoirs at home and abroad, but because unconventional oil and gas reservoirs usually show poor physical properties and are water-sensi...
