Embodiment 1

[0035] see Figure 1-3 , the embodiment of the present invention provides a sample flushing device, which is suitable for extracting and determining the content of crude oil in oil-bearing rocks. The sample flushing device includes a flushing filter 1 and a liquid controller 2,

[0036] The flushing filter 1 comprises a trumpet-shaped container opening 11, a cylindrical straight tubular flushing pipe 12 and a filter pipe 13, one end of the flushing pipe 12 is matched with the thin end 111 of the container 11, and the flushing pipe 12 The other end is connected with one end of the filter pipe 13, and the other end of the filter pipe 13 is closed and is provided with an outflow hole 131 at the closed place, and the diameter of the outflow hole 131 is less than the pipe diameter of the filter pipe 13;

[0037] The liquid controller 2 comprises a solvent tank 21 provided with two ports, a two-way valve 22, and a drain pipe 23. One port of the two-way valve 22 communicates with the...

Embodiment 2

[0046] see Figure 4 , the embodiment of the present invention provides a method for crude oil extraction and content determination of oily rocks, which is suitable for using the sample puncher as described in Example 1, and the method includes the following steps:

[0047] S1: Plug the filter material in the filter tube;

[0048]Specifically, in the crude oil extraction and content determination of oil-bearing rocks, pure crude oil must be obtained in order to obtain accurate crude oil quality and correct crude oil content data. However, the current crude oil extraction device has no filtering function or only rough filtering function, the obtained extract often contains a certain amount of impurities such as rock particles. Therefore, after the extraction work is completed, the extract must be specially filtered to obtain pure crude oil, which not only prolongs the experiment cycle, but also increases workload etc. The method adopts the sample flushing device described in ...

Abstract

The invention discloses a sample flushing device which belongs to the technical field of crude oil extraction experiments. The sampling flushing device comprises a flushing filter and a liquid control device. The flushing filter comprises a horn-shaped material containing port, a flushing pipe and a filter pipe. One end of the flushing pipe is in matched connection with a fine-port end of the material containing port, and the other end of the flushing pipe is connected to the filter pipe. One end of the filter pipe is closed and a tapping hole is arranged at the closed position. Diameter of the tapping hole is less than pipe diameter of the filter pipe. The liquid control device comprises a solvent tank provided with two ports, a two-way valve and a drainage tube. one port of the two-way valve is communicated with the solvent tank, and the other port of the two-way valve is connected to one end of the drainage tube, the other end of which is plugged-in a fine-port end of the material containing port. By placing a rock sample into the flushing filter and controlling the liquid control device to add a solvent ceaselessly and automatically, crude oil can be continuously and efficiently extracted from the rock sample. Experimental steps are simple and experimental period is short. Sample analysis speed is raised. Meanwhile, matching units of the experiment are simple, and experiment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of crude oil extraction experiments, in particular to a sample puncher and a method for extracting crude oil from oil-bearing rocks and determining its content. Background technique [0002] Crude oil extraction and content determination of oil-bearing rocks is an analytical experiment project that is often done in petroleum exploration and development research. At present, this analytical experiment is usually based on the performance of chloroform in dissolving crude oil but not in dissolving rocks. Soxhlet extractors are used. Chloroform is used to extract crude oil by cyclic immersion and extraction of oily rocks. [0003] However, in the course of long-term experiments, the inventors found that this method of using a Soxhlet extractor for crude oil extraction and content determination, no matter what kind of rock sample, has at least the following problems: [0004] The analysis steps of this method ar...
