Abstract

Embodiments of the invention provide a method and a device for determining the type of an oil and gas reservoir. The method comprises the following steps of obtaining type and content data of diamantane series compounds in a crude oil sample of a reference oil and gas reservoir; carrying out analysis and processing on the reference oil and gas reservoir to obtain the type of the reference oil and gas reservoir; and carrying out fitting analysis and processing on the type and content data of the diamantane series compounds and the type of the reference oil and gas reservoir and determining a fitting relation between the type and content data of the diamantane series compounds and the type of the reference oil and gas reservoir; and determining the type of a to-be-tested oil and gas reservoir based on the fitting relation and the type and content data of the diamantane series compounds in the obtained crude oil sample of the to-be-tested oil and gas reservoir. Through utilizing the technical scheme provided by the embodiments of the invention, the reservoir type of the to-be-tested oil and gas reservoir can be determined quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a method and device for determining the type of oil and gas reservoirs. Background technique [0002] With the improvement of the degree of exploration, more and more oil fields have entered the middle and late stage of development and exploration, the number of large oil and gas reservoirs is decreasing, and complex oil and gas reservoirs, small oil and gas reservoirs and deep oil and gas reservoirs have gradually become the main objects of exploration. Among the currently explored complex oil and gas reservoirs, small oil and gas reservoirs and deep oil and gas reservoirs, there may be various types of oil and gas such as volatile oil reservoirs, condensate gas reservoirs with oil rings, wet gas reservoirs, condensate gas reservoirs, and gas reservoirs. Tibetan. For different types of oil and gas reservoirs, different exploration methods and development technol...
