Definitions

  • An example implementation of the subject matter described within this disclosure is a second method with the following features.
  • An open system pyrolysis is performed within a pyrolysis chamber on a hydrocarbon source rock sample that includes fragments having an equivalent spherical diameter of substantially at least one centimeter.
  • Performing the open system pyrolysis results in a pyrolyzed rock sample.
  • Hydrocarbons released by the rock sample in response to the open system pyrolysis are recovered.
  • a first quantity of hydrocarbons released in response to the open system pyrolysis is determined.
  • a thermo-vaporization is performed within the pyrolysis chamber on the pyrolyzed rock sample. Hydrocarbons released by the rock sample in the pyrolysis chamber in response to the thermo-vaporization are recovered.
  • FIG. 4 is a plot of an example of a thermo-vaporization in a sample crushing chamber at a constant temperature.
  • the hydrocarbon source rock sample can be obtained from a hydrocarbon source rock to be studied.
  • the grain size of hydrocarbon source rock in the subsurface affects a distance through which hydrocarbons generated and trapped in the rock need to traverse before being released during natural kerogen maturation.
  • the hydrocarbon source rock sample is selected to have a grain size that is substantially similar to a grain size of hydrocarbon rock in the subsurface.
  • the experimental conditions of the artificial kerogen maturation can be made closer to the conditions of natural kerogen maturation. That is, in such conditions, the hydrocarbon in the rock sample will need to traverse a distance that is closer to the distance through which the hydrocarbons trapped in the rock need to traverse before being released during natural kerogen maturation.
  • the hydrocarbon expulsion efficiency determined for the hydrocarbon source rock sample 104 following the artificial kerogen maturation will, consequently, be a more accurate prediction of the hydrocarbon expulsion efficiency of the hydrocarbon source rock in the subsurface following natural kerogen maturation.
  • the hydrocarbon source rock sample can additionally be characterized in terms of the Total Organic Carbon (TOC) content as weight percent (wt %) of the source rock and determination of kerogen type using conventional organic geochemical techniques.
  • the TOC content can be determined by LECO TOC analyzer where the organic carbon is measured after removal of carbonate carbon.
  • the TOC content can also be determined by Source Rock Analyzers which have pyrolysis and oxidation ovens.

Abstract

L'invention concerne une pyrolyse à système ouvert d'un premier échantillon de roche mère d'hydrocarbures obtenue à partir d'un système naturel qui est effectuée à l'intérieur d'une chambre de pyrolyse en maintenant la chambre de pyrolyse à une température sensiblement constante. Les hydrocarbures sont récupérés dans la chambre de pyrolyse, libérés par le premier échantillon de roche mère d'hydrocarbures. Une thermovaporisation est effectuée à l'intérieur de la chambre de pyrolyse sur l'échantillon pyrolysé à une température sensiblement constante. Une première efficacité d'expulsion d'hydrocarbures d'une roche mère d'hydrocarbures est déterminée. Un second échantillon de roche mère d'hydrocarbures est broyé jusqu'à une taille de grain inférieure ou égale à 250 micromètres. Une seconde pyrolyse est effectuée sur l'échantillon de roche mère d'hydrocarbures broyé en maintenant la chambre à une température sensiblement constante. Une seconde efficacité d'expulsion d'hydrocarbures de la roche mère d'hydrocarbures dans le système naturel est déterminée. La première efficacité d'expulsion d'hydrocarbures est vérifiée à l'aide de la seconde efficacité d'expulsion d'hydrocarbures.
