Abstract

The invention provides a calculation method and device of hydrocarbon source rock hydrocarbon generation and expulsion strength. The calculation method comprises the steps that the logging data of a single well are acquired, wherein the logging data at least comprise acoustic wave time difference, natural gamma, resistivity and depth scale; according to acoustic wave time difference, natural gamma, resistivity and depth scale and respective parameters, lithology in an interval identification single well is identified; acoustic wave time difference, natural gamma and resistivity are substituted into a hydrocarbon generation strength calculation formula corresponding to lithology to calculate the lithology hydrocarbon generation strength; and the hydrocarbon generation strength is substituted into a hydrocarbon generation strength relation to calculate the lithology hydrocarbon expulsion strength. According to the invention, a number of parameter factors are considered; calculated results are accurate, and accord with the actual geologic environment of the logging; and a precise data support is provided for subsequent logging.

Description

technical field

[0001] The invention relates to oilfield logging technology, in particular to a method and device for calculating the intensity of hydrocarbon generation and expulsion of source rocks. Background technique

[0002] With the development of my country's petroleum exploration technology, the exploration field has been continuously expanded, and has developed from conventional clastic rock reservoirs to carbonate rock reservoirs, and the evaluation of carbonate rock source rocks has become an important content. In carbonate source rocks, there are various lithologies with different hydrocarbon-generating capabilities, and even the same lithology has different hydrocarbon-generating potentials due to the different time and environment when it was formed. Therefore, accurate evaluation of source rocks has become the key content of evaluation of carbonate rock resources.

[0003] In the field of petroleum exploration, the evaluation of source rocks is the primary t...
