Embodiment Construction

[0052] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0053] Such as figure 1 as shown, figure 1 It is a flow chart of the multivariate logging calculation method for organic carbon and hydrocarbon generation potential of saline lake facies source rocks of the present invention.

[0054] In step 101, the standardization and normalization of the logging curve helps to eliminate the influence of the difference between the logging instrument and the logging series on the evaluation of the source rock.

[0055] First, standardize and normalize the well logs of different wells. In order to eliminate the impact of the differences between logging tools and logging series on source rock evaluation, it is necessary to standardize the acoustic time difference AC and the true formation resistivity Rt, normal...

Abstract

The invention provides a multivariate well logging computing method for the total organic carbon and the hydrocarbon generating potential of hydrocarbon source rocks in salt-lake facies. The method comprises the steps of conducting standardization and normalization on logging curves of different wells, conducting core proper-horizon restoration on hydrocarbon source rock total organic carbon data measured through experiments, classifying the hydrocarbon source rocks in the salt-lake facies, reading logging curve data, obtained after core proper-horizon restoration correction, of total organic carbon experimental points, conducting R-type hierarchical clustering analysis on the logging data and the total organic carbon of the rocks, establishing logging evaluation models of the TOC according to different lithological characters, and conducting computing to obtain TOC data so as to work out rock pyrolysis data. The multivariate well logging computing method for the total organic carbon and the hydrocarbon generating potential of the hydrocarbon source rocks in the salt-lake facies can be used for evaluating the mass and the hydrocarbon generating potential of the hydrocarbon source rocks, of special lithological characters, in the salt-lake facies, and the method can be applied to provide a great number of evaluation data for hydrocarbon source rock evaluation and oil and gas resource quantity evaluation.

Description

technical field [0001] The invention relates to the technical field of petroleum development, in particular to a method for multivariate well logging calculation of organic carbon and hydrocarbon generation potential of salt lake facies source rocks. Background technique [0002] Organic carbon content (TOC) is an important index for evaluating source rocks and oil and gas resources. However, due to the limited number of test samples, the organic carbon obtained by experimental methods is often discontinuous on geological profiles. Moreover, affected by factors such as sedimentary facies, paleo-productivity, and paleo-environment, the properties of source rocks have obvious heterogeneity, and the organic matter content in source rocks varies greatly. The contribution of high-peak source rocks is often neglected in the evaluation of source rocks, especially in areas where coring data is lacking, and traditional geochemical methods are severely restricted. Based on the measur...
