Description

Electric sealing porosity clamp holder

Technical Field

The utility model relates to an experimental apparatus technical field, concretely relates to electrically-operated seal porosity holder.

Background

Porosity reflects the degree of development of rock voids, and refers to the ratio of the sum of all pore space volumes in a rock sample to the volume of the rock sample, referred to as the total porosity of the rock, expressed as a percentage, with the ability to characterize reservoir fluids. The greater the porosity of the reservoir, the greater the amount of fluid that can be accommodated and the better the reservoir performance. At present, the porosity of the rock core is generally determined by a direct laboratory measurement method at home and abroad.

In a laboratory, according to the Boyle's law, at a constant temperature, the volume of a core chamber is fixed, the smaller the volume of a solid phase put into a core chamber rock sample is, the larger the volume occupied by gas in the core chamber is, and the lower the equilibrium pressure is after the core chamber rock sample is communicated with a standard chamber; and conversely, when the solid phase volume of the rock sample put into the core chamber is larger, the higher the equilibrium pressure is, the higher the volume of the standard block and the standard curve of the equilibrium pressure are drawn. And (4) measuring the equilibrium pressure of the rock sample to be measured, reversely checking the solid phase volume of the rock sample according to a standard curve, and calculating according to a formula to obtain the porosity of the rock sample.

However, in the experimental process, due to the existence of human factors, the force is inconsistent when the T-shaped rotating handle of the core holder is rotated, so that the sealing degree of the core chamber is inconsistent, and the final experimental result is inaccurate.
