Method for measuring water content in high-water-content gas-liquid mixed non-polar hydrocarbon

The invention discloses a method for measuring the water content in high-water-content gas-liquid mixed non-polar hydrocarbon, which comprises the following steps: sampling, weighing a sample, absorbing methanol, weighing methanol after absorption, and calculating by adopting a formula to obtain the water content. According to the method, the characteristic that non-polar hydrocarbon is insoluble in methanol is creatively utilized, methanol is used for absorbing water in a gas-liquid mixed hydrocarbon sample, part of the gas-liquid mixed hydrocarbon volatilizes, and the other part of the gas-liquid mixed hydrocarbon is layered with methanol, so that the gas-liquid mixed hydrocarbon is separated from the water; the water content in the methanol is measured after the methanol absorbs water, and the content of free water in the gas-liquid mixed hydrocarbon is converted by a formula according to the change of the water content before and after the methanol is absorbed, so that data guidance can be accurately prov
