Abstract

The invention relates to an alcohol-based fracturing fluid preparation method, which comprises: S1, injecting a thickening agent into a preparation chamber through a first material inlet, and swelling with water in the preparation chamber; S2, after first preset time, enabling a cross-linking agent, a foaming agent, a compound agent and a foam stabilizer to be injected into the preparation chamber respectively through a second feeding port, a third feeding port, a fourth feeding port and a fifth feeding port to be stirred and mixed with the swelled thickening agent to form alcohol-based fracturing fluid; and S3, injecting the alcohol-based fracturing fluid into the detection chamber through the first pipeline, adopting a central control unit to control the detection chamber to be inverted multiple times, after second preset time, adopting the central control unit to discharge the alcohol-based fracturing fluid through a second pipeline, adopting the central control unit to obtain the stability of the alcohol-based fracturing fluid, and judging that the alcohol-based fracturing fluid with the qualified stability is output. According to the invention, the central control unit is arranged to adjust parameters of each component, so that the stability of the produced alcohol-based fracturing fluid meets a 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...
