Problems solved by technology

However, in some areas with low temperature in winter, when the temperature reaches below zero, the conventional bio-glue cannot quickly dissolve in ice water and release the viscosity to achieve the effect of thickening, which makes the application of bio-glue difficult, and even some areas stop drilling and exploration in winter, and construction stagnates , increasing the construction period and cost
In addition, conventional bio-glue is not easy to formulate into a solution when used in some special environments, and it is difficult to achieve the expected effect. For example, when used for offshore drilling, conventional bio-glue is difficult to adapt to the salinity of seawater in different sea areas
In addition, conventional bio-glue solutions in high-temperature environments with temperatures as high as 120°C to 150°C, such as more than 3,000 meters deep underground, have viscosity that decreases as the temperature increases, and cannot maintain normal thickening and suspension properties. Effectively carries sediment and lubricates drill bits

Abstract

The invention discloses a biopolymer thickener as well as a preparation method and application thereof, the biopolymer thickener is prepared from a biogel, a suspension and an emulsifier, and the weight percentage of the biogel in the biopolymer thickener is not more than 60%; wherein the weight percentage of the suspension in the biopolymer thickener is not less than 30%; and the balance of emulsifier; the suspension is a mixture of organic bentonite and grease. The biopolymer thickener provided by the invention has the characteristic of low temperature resistance; the problem that the dispersion liquid is difficult to prepare under a low-temperature condition can be solved; the characteristics of heat resistance, salt resistance and rapid dispersion and dissolution are also realized; besides, the biopolymer thickener can be directly used without preparation treatment, a high-viscosity solution with good suspension property can be generated even under low concentration, and the biopolymer thickener has better lubricating and emulsifying effects and can be used in multiple technical fields such as exploration, oil field drilling, printing ink and fire protection.

Description

technical field [0001] The present invention relates to the field of industrial technology, in particular to a biopolymer thickener, a preparation method of the biopolymer thickener and the use of the biopolymer thickener in technical fields including exploration, oil field drilling, ink, fire protection, etc. Applications. Background technique [0002] Relevant data show that China's recoverable oil resources are estimated to be 15 billion tons, about 8.5 billion tons to be discovered and proven, accounting for 57% of the proven recoverable oil resources. This part of oil resources to be proven is mainly distributed in the four basins of Tarim, Junggar, Qaidam, and Turpan-Hami, which are the main replacement areas for China's oil production. At the same time, 73% of these resources are buried below 5,000 meters. The earth's average geothermal gradient is 3°C / 100m, and high-quality drilling mud with high temperature resistance is required to drill and exploit oil in these ...
