Abstract

The invention relates to the technical field of semi-permeable membrane agents, and especially relates to an organosilicate semi-permeable membrane agent. The agent comprises the following components in parts by mass: 15-19 parts of alkylamidoamine, 20-30 parts of sulfoisophthalic acid, 5-12 parts of diethylenepolyamine, 10-20 parts of glycerin, 15-32 parts of silicic acid, 4-10 parts of potassium hydroxide, 15-20 parts of sodium 2-hydroxybenzenesulfonate, and 100-130 parts of deionized water. The formula is employed, the organosilicate semi-permeable membrane agent has high inhibition effects for hydration swelling and dispersion of shale, and the agent is a strong inhibitor with excellent performance and can prevent collapse of borehole walls and reduce complex downhole conditions. In addition, the agent does not pollute environment, and the agent has low cost with less energy consumption.

Description

technical field [0001] The invention relates to the technical field of semipermeable membrane agents, in particular to organosilicate semipermeable membrane agents. Background technique [0002] Inhibitors, also known as anti-slump agents, are mainly used to configure inhibitory drilling fluids. When drilling into shale formations, they can keep shale from hydrating and expanding, and prevent them from collapsing when drilling into unconsolidated formations. [0003] At home and abroad, a lot of research has been done on the application of semi-permeable membrane technology in the field of drilling fluid, and the semi-permeable membrane performance and inhibition ability of the treatment agent with semi-permeable membrane performance have been systematically studied. At present, studies have confirmed that the treatment agents with semi-permeable membrane properties include polyols (polyethylene glycol, polyglycerol, MEG), silicates, etc., but the inhibitors of organic silic...
