Problems solved by technology

At present, a large number of relevant studies have been carried out on the evaluation of oil and gas content and the distribution of oil and gas, but there are still some problems and deficiencies; most of the evaluation methods used are based on geological risk probability method, multiple regression method, etc. Scoring is often highly subjective, lacking in combination with actual exploration data, and the evaluation model is relatively simple, poor in reliability and practicability

Abstract

The invention provides a quantified evaluation method and apparatus for oil and gas contained in an oil field and relates to the technical field of oil and gas field exploration. The method includes the following steps: based on oil sources conditions, migration and accumulation conditions, reservoir conditions, entrapment conditions, reserving conditions and complete conditions of an oil field, determining buried depth, porosity, counterpart, permeability, top interlayer thickness and a Shale Gouge Ratio (SGR) index of the oil field, and introducing the buried depth, porosity, counterpart, permeability, top interlayer thickness and a Shale Gouge Ratio (SGR) index of the oil field to an oil and gas contained probability regression model (as shown in the description) to obtain an oil and gas contained probability of the oil gas. The method and the apparatus achieve the quantified calculation of the probability of oil and gas contained in the oil field, increase the reliability and practicality of the evaluation method for oil and gas contained in the oil field, and meets the requirements form precise exploration of oil and gas wells.

Description

technical field [0001] The invention relates to oil and gas field exploration and development technology, in particular to a quantitative evaluation method and device for the oil and gas content of an oil field. Background technique [0002] Petroleum-bearing property evaluation is an important part of petroleum geology research. Through effective quantitative characterization of oil-gas content, it can directly reflect the distribution of oil and gas, deepen the understanding of oil and gas accumulation, and facilitate decision-making and deployment. It has received more and more attention in oil and gas exploration. At present, a large number of relevant studies have been carried out on the evaluation of oil and gas content and the distribution of oil and gas, but there are still some problems and deficiencies; most of the evaluation methods used are based on geological risk probability method, multiple regression method, etc. Scoring is often highly subjective, lacking in...
