Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] The rock density measurement method provided by the invention simulates the high temperature and high pressure conditions of oil and gas reservoirs, estimates the density of actual oil and gas reservoirs according to the measurement results, and provides guidance for the exploration and development of oil and gas reservoirs. Each step of the rock density measurement method of the present invention will be described in detail below. In addition, the invention also provides a rock density measuring device implementing the rock density measuring method.

[0033] Such as figure 1 As shown, the rock density measurement method includes the following steps: S1 is step 1, making a rock sample, and constructing the rock sample into a cylinder. Facilitates the calculation of the volume of rock samples.

[0034] Such as figure 1 As shown, S2 is step 2, weighing the quality ...

Abstract

The invention relates to a rock density measurement and a rock density measurement device, wherein the method includes the following steps: (1) making a rock sample which is cylindrical in structure; (2) weighing the mass of the rock sample; (3) measuring the axial height and the bottom diameter of the rock sample; (4) placing the rock sample in a high pressure chamber; (5) increasing the temperature of the high pressure chamber, applying axial pressures on the bottom surface and the top surface of the rock sample for fixing the rock sample, and applying a radial pressure to a side surface of the rock sample; (6) detecting the axial strain quantity of the rock sample and the radial deformation quantity of the bottom surface of the rock sample; and (7) obtaining the density of the rock sample. The method can be used for measuring the rock density at a high temperature and under a high pressure.

Description

technical field [0001] The invention relates to the technical field of rock physical characteristics, and specifically designs a rock density measurement method. In addition, the invention also relates to a rock density measuring device. Background technique [0002] As we all know, with the continuous excavation and exploitation of oil and gas fields on the surface of the earth's crust, shallow oil and gas resources become less and less, and people begin to turn their attention to deep oil and gas reservoirs. In the study of deep oil and gas fields, the change of physical properties of oil-bearing rocks under high temperature and high pressure conditions is the key factor in the study of the formation, change and migration of oil reservoirs. The detection of physical properties of oil-bearing rocks under high temperature and high pressure conditions, especially the detection of oil-bearing rock density, has important guiding significance for the development of oil and gas ...
