WELL LOGGING EVALUATION OF MARINE HYDROCARBON SOURCE ROCK IN TAZHONG AREA
摘要
Abstract
To the low organic abundance and strong heterogeneity of the marine hydrocarbon source rock, this paper analyzes the well logging response characteristics of the marine hydrocarbon source rock in Tazhong area, and builds the plate for quantitative identification of Ordovician source rock in Tazhong area and the classification and identification model for marine source rock in the studied area. In the evaluation of organic matter abundance, the elastic parameters of hydrocarbon source rock, the ratio of uranium and thorium content, the difference of natural gamma, and the resistivity in Tazhong area are used as the input layers, and a BP neural network model based on the genetic algorithm is built. Practice shows that the TOC value predicated by this method is as accurate and reliable as the rock sample analysis result, providing the basis for the evaluation of effective hydrocarbon source rock.关键词
