Problems solved by technology

When performing PVT simulation, it is necessary to accurately measure the gas-liquid ratio of hydrocarbon inclusions. At present, it is generally obtained by laser confocal scanning focal microscope. However, due to the lack of standard samples, there is no report on the calibration method of this test method.

Embodiment Construction

[0011] Such as figure 1 As shown, the synthesis method of the standard sample of hydrocarbon inclusions used to correct the determination of the gas-liquid ratio adopts the following steps: temperature setting; saturated solution preparation and sealing; standard oil sample loading; solution evaporation and crystallization; crystal separation; sample preparation; Microscopic observation to select hydrocarbon inclusions.

[0012] Regarding temperature setting: set the oven temperature to the experimental temperature of 80°C, and the pressure to normal pressure.

[0013] Saturated solution preparation and sealing: Prepare a saturated sodium chloride solution at 80°C in a 250ml beaker, seal the mouth of the beaker with a plastic film, and make holes in the plastic film to place the glass tube.

[0014] The method of loading the standard oil sample is as follows: cut the glass tube, wash and dry; insert a glass tube with a diameter of about 5 mm and a length of about 150 mm into ...

Abstract

The invention belongs to the field of geochemistry and in particular relates to a method for synthesizing a hydrocarbon coated standard sample for correcting a gas-liquid ratio measured by a laser confocal scanning microscope. The standard sample can be used for correcting the laser confocal scanning microscope and calibrating the error of the measured hydrocarbon coated gas-liquid ratio, and the gap in the field is filled. The method for synthesizing the hydrocarbon coated standard sample comprises the following steps: setting the temperature; preparing a saturated solution and sealing; filling a standard oil sample; evaporating and crystallizing the solution; separating the crystal; making the sample piece; performing microscopic observation and sorting the hydrocarbon coated body; and calculating the theoretical gas-liquid ratio. The hydrocarbon coated body synthesis method has the characteristics that the method is simple, convenient, simple in operation, low in cost and good in effect, the sample is transparent and easy to observe, the amount of the synthesized hydrocarbon coated bodies is large, the theoretical gas-liquid ratio is easy to calculate and the like.

Description

technical field [0001] The invention belongs to the field of oil and gas geochemistry, and in particular relates to a method for synthesizing a hydrocarbon inclusion standard sample for calibrating a laser confocal scanning microscope to measure a gas-liquid ratio. Background technique [0002] In oil and gas basins, hydrocarbon inclusions are direct samples that record oil and gas accumulation, and preserve the original information of oil and gas migration and accumulation. The temperature and temperature of oil and gas migration and oil and gas accumulation can be restored through its analysis and PVT simulation calculation. pressure. When performing PVT simulation, it is necessary to accurately measure the gas-liquid ratio of hydrocarbon inclusions. At present, it is generally obtained by laser confocal scanning focal microscopy. However, due to the lack of standard samples, there is no report on the calibration method of this test method. In this regard, the present inv...
