Abstract

The invention discloses an oil source comparison method and belongs to the technical field of exploration. The invention solves a technical problem of low accuracy of a comparison result of oil sources in the prior art. The oil source comparison method comprises the steps of: 1) performing group component separation of crude oil and potential source rocks, and measuring the quantities of stable carbon isotopes of all the separated group components; 2) calculating the composition of stable carbon isotopes of all group components in the crude oil and the potential source rocks; 3) by means of the composition of stable carbon isotopes in the same group component in the crude oil and the potential source rocks, calculating relationship coefficient of the same group component in the crude oil and the potential source rocks; and 4) according to the relationship coefficient of stable carbon isotope composition the same group component in the crude oil and the potential source rocks, determining the relationship of the crude oil and the potential source rocks.

Description

technical field [0001] The invention relates to the technical field of exploration, in particular to an oil source comparison method. Background technique [0002] Petroleum is an important resource in today's world. It is widely used in energy, chemical industry, pharmaceuticals, agriculture, aerospace and other aspects. As people use more and more petroleum, how to use this non-renewable resource more effectively is the There are major hotspots of research. [0003] In order to effectively utilize oil, it is necessary to understand the source of oil so as to evaluate its exploration potential and exploration direction, which requires the use of oil source correlation technology. Oil source correlation is the work of determining the genetic connection between oil and source rocks based on geological and geochemical evidence. Stable carbon isotope composition (δ 13 The size of C) depends on the nature of the original organic matter, the environment in which it was formed,...
