Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The structure of the core oil washing instrument of the present invention is as figure 2 shown. Overall, the core oil washing instrument includes a sample cleaning system and a waste liquid treatment system.

[0034] The sample cleaning system includes a core kettle 1, a liquid storage tank 3, a gas injection pump 5 and a negative pressure system.

[0035] The core kettle is a closed container for cleaning rock samples, and its specific structure is as follows: image 3 As shown, the internal space is divided into upper and lower chambers by a heat-conducting inclined partition 107 . The thermally conductive inclined partition is set to be high on one side and low on the other side. image 3 The middle performance is high on the right a...

Abstract

The invention relates to a rock core oil cleaning instrument. The rock core oil cleaning instrument comprises a solution storage tank and a rock core kettle for cleaning a rock core, the solution outlet of the solution storage tank is connected to the solution inlet of the rock core kettle through a pipeline, the waste liquid outlet of the rock core kettle is connected with the liquid inlet of a distillation kettle through a pipeline, and the distillate outlet of the distillation kettle is connected to the solution inlet of the solution storage tank through a pipeline. A small circulating oilcleaning system is formed by the solution storage tank, the rock core kettle and the distillation kettle, an oil washing solution in the solution storage tank flows into the rock core kettle through the pipeline to clean a rock core to be cleaned, a waste liquid obtained after cleaning completion flows into the distillation kettle through the pipeline and is distilled, and then the obtained distillate is discharged into the solution storage tank again, so that circulating oil cleaning operation of the rock core is achieved. The rock core oil cleaning instrument recycles the oil cleaning wasteliquid on the basis of ensuring that the rock core is cleaned, so that the energy is saved, and the oil cleaning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum geological exploration, in particular to a core oil washing instrument. Background technique [0002] In the process of petroleum geological exploration and development, it is necessary to understand and understand the geological structure and evolution process, mainly through the analysis of various technical data such as rock composition, age, and structure. [0003] The relevant data of petroleum geology mainly include: saturation, porosity, permeability, scanning electron microscope, casting analysis, rock sensitivity, chemical composition and more than 40 related options. Among them, porosity, permeability, electron microscope scanning, casting analysis, rock sensitivity and other more than a dozen items, the rock core samples should be cleaned before analysis to remove the grease in the samples. [0004] The shape of the sample is divided into regular and irregular. The shape of the regul...
