Problems solved by technology

[0003] At present, most of the fracturing fluids used in oil fields use hydroxypropyl guar gum as a thickening agent, which can form a stable fracturing fluid with good temperature resistance and shear resistance, but guar gum is mainly produced in India and Pakistan , cannot be produced on a large scale in China, and its price fluctuates greatly, so there is considerable research space for finding a glue that can replace guar gum

Abstract

The invention relates to a vegetable gelatin fracturing fluid and a preparation method thereof. The fracturing fluid used by the oil field at present mostly adopts hydroxypropyl guar gum as a thickening agent, and has high cost. The preparation method for the vegetable gelatin fracturing fluid comprises the following steps of: reacting water, glycerol and borax to obtain an organic-boron cross-linking agent; reacting butyl titanate, triethanolamine and glycerol to obtain an organic titanium high-temperature stabilizer; mixing water with konjac glucomannan to obtain a base solution; and adding the organic-boron cross-linking agent and the organic titanium high-temperature stabilizer to prepare the vegetable gelatin fracturing fluid. The fracturing fluid provided by the invention adopts the konjac glucomannan as the thickening agent which has good viscosity and temperature and shearing resistance, adopts the self-prepared organic-boron cross-linking agent which has high cross-linking density and strength, and is additionally added with the organic titanium high-temperature stabilizer, so that the konjac glucomannan fracturing fluid has good temperature and shearing resistance. Moreover, the content of the rubber-crushed residues is extremely low, and the damage degree to the earth surface is extremely low.

Description

Technical field [0001] The present invention involves a fracture liquid, which specifically involves a plant glue crack and its preparation method. Background technique [0002] With the development of exploration technology, the oil storage layer is getting deeper and deeper, and the degree of mineralization of strata and stratigraphy is getting higher and higher. Therefore, it is very important to study high -temperature storage to increase the harvesting rate.Studying a fracturing liquid system suitable for high -temperature oil collection can provide methods to solve the technical difficulties that improve the final harvesting rate of oilfields, and have huge practical application value.Therefore, the research of high temperature -resistant agents and its fracture liquid system is the most important research content for high -temperature oil collection fracture production. [0003] At present, the fracture liquid used in oil fields is mostly used as a thick agent with hydroxy...
