What is the normal amount of natural gas used by residents in a month?

A household of three people can use up to 25-30 cubic meters of natural gas a month. This is within normal range.

Under normal circumstances, taking a family of three as an example, the energy consumption situation is as follows:

1 cubic meter of natural gas can provide a family of three with cooking and bathing for 2 days on average; according to a An average of 30 days per month means about 15 words per month.

If converted into electricity and gas, the calorific value of 1 kilowatt hour of electricity is about 860 kcal, and the calorific value of 1 cubic meter of natural gas is about 9227 kcal.

About 10 degrees of electric heating value (without loss) is equivalent to 1 cubic meter of natural gas. Taking losses into account, the efficiency of natural gas is 40% and the efficiency of electricity is 80%.

It probably requires the same combustion effect. Using 10 kilowatt hours of electricity is equivalent to using 2 cubic meters of natural gas. Generally speaking, if an ordinary household uses 1,000 kilowatt-hours of electricity a year, it is equivalent to using 200 cubic meters of natural gas. The average is about 16 words per month. The monthly gas consumption for a family of three is approximately 15-17 words.

Composition classification

1. Natural gas can be divided into free state, dissolved state, adsorbed state and solid hydrate according to the phase state existing underground. . Only free natural gas can be developed and utilized after gathering to form natural gas reservoirs.

2. Natural gas can be divided into associated gas and non-associated gas according to the form of storage and generation.

Associated gas: Oil field gas that accompanies the production of crude oil and is produced at the same time as crude oil. Among them, associated gas is usually the volatile part of crude oil, which exists in the form of gas above the oil-bearing layer. It is found in all formations with crude oil, but the proportion of oil and gas is different. Even within the same field, the sources of oil and gas are not necessarily the same. They come together in the same rock reservoir through different pathways and processes.

Non-associated gas: including pure gas field natural gas and condensate gas field natural gas, both of which exist in gaseous state in the formation.

After the natural gas in the condensate gas field flows out of the wellhead from the formation, as the pressure decreases and the temperature increases, it separates into two phases of gas and liquid. The gas phase is the natural gas in the condensate gas field, and the liquid phase is the condensate liquid, which is called Condensate. If it is non-associated gas, it is not related to liquid accumulation and may originate from plant matter. The world's natural gas production mainly consists of gas field gas and oil field gas. The exploitation of coalbed methane has received increasing attention.

3. According to the state of natural gas reserves, it is divided into three types: structural natural gas, water-soluble natural gas, and coal mine natural gas. Structural natural gas can be divided into wet natural gas accompanying crude oil production and dry natural gas without liquid components.

4. Natural gas can be divided into biogenic gas, oil-type gas and coal-type gas according to its origin. Gases of inorganic origin, especially non-hydrocarbon gases, have received great attention.

5. According to the occurrence of natural gas in the underground, it can be divided into oil field gas, gas field gas, condensate gas, water-soluble gas, coal bed methane, and solid gas hydrates.
