Problems solved by technology

The main problem of these methods is that the coarse crushing process and the fine crushing process are completed in two different systems, the coarse crushing process of large core samples is carried out in the open system, and the coarse crushing process and the sample transfer to the closed fine crushing system process There is desorption and loss of gas substances in rocks, and the amount of loss cannot be measured, which will inevitably lead to low gas content results in the final rock, which cannot accurately reflect the real gas content in rock samples
To the test of rock light hydrocarbon, the method used at present mainly adopts the

Abstract

The invention relates to an apparatus and a method for combined testing of the gas content and the C1-C15 light hydrocarbon components of rock. The apparatus comprises a sealed sample breaking tank, aheating box, a chromatography box, a vaporization chamber, a detector, an intelligent cold trap, a chromatography column and a vaporization chamber, wherein a helium gas inlet pipeline and a helium gas outlet pipeline respectively pass through both sides on the top portion of the heating box, one end of the helium gas inlet pipeline on one side is connected to a helium gas bottle, the other end is connected to the first gas valve of the sample breaking tank, one end of the helium gas outlet pipeline on the other side is connected to the vaporization chamber, and the other end is connected tothe second gas valve of the sample breaking tank. According to the present invention, the operation is convenient, the solvent is not used, the working efficiency is improved, and the problems of thenon-uniformity of the sample and the influence caused by the ambient temperature can be overcome.
