Abstract
The invention discloses a surfactant complex-based high temperature-resistant solvent. The surfactant complex-based high temperature-resistant solvent is used for unconventional energy thickened oil steam-injection thermal recovery and through the surfactant complex-based high temperature-resistant solvent, a steam-chemical assistant combined exploitation method is formed. The surfactant complex-based high temperature-resistant solvent comprises a dispersant, a surfactant complex and an inorganic salt, and concretely, the surfactant complex-based high temperature-resistant solvent comprises, by mass, 5-10 parts of the dispersant, 10-30 parts of the surfactant complex, 5-10 parts of the inorganic salt and 80-50 parts of water. Through compounding of a fluorocarbon surfactant and a hydrocarbon surfactant, the surfactant complex-based high temperature-resistant solvent can resist a temperature of 300 DEG C and can improve steam transmission efficiency and stripping, viscosity reduction and displacement effects on thickened oil in thickened oil steam-injection recovery and especially in thickened oil steam assisted gravity drainage (SAGD).
Description
technical field [0001] The invention relates to the field of petroleum exploitation chemistry, and is a high-temperature-resistant solvent based on the compounding of surfactants, which is applied in the steam thermal recovery process of unconventional energy heavy oil to form a steam and chemical auxiliary agent compound recovery method. Background technique [0002] At present, the development method of heavy oil is mainly thermal recovery, including steam huff and puff, steam flooding, burning oil layer and steam assisted gravity drainage (SAGD) and other technologies. Among them, steam huff and puff and steam flooding technologies were developed earlier, and the theory is relatively complete, and they have been widely used in heavy oil recovery. However, in the process of steam injection production, on the one hand, due to the difference in viscosity between steam and crude oil and the influence of reservoir heterogeneity, steam overlaps, which reduces the volumetric swe...
