岩石孔隙度和渗透率的测量流程## English Answer ##。

Porosity and permeability are two important properties of rocks that are used to characterize their ability to store and transmit fluids. Porosity is the ratio of the volume of void space in a rock to the total volume of the rock, while permeability is the ability of a rock to allow fluids to flow through it.There are a number of different methods that can be used to measure porosity and permeability. One common method is the gas expansion method. This method involves placing a sample of rock in a chamber and then filling the chamber with a gas. The pressure of the gas is then increased until it is equal to the pressure of the gas in the pores of the rock. The volume of gas that is required to fill the chamber is then measured, and this volume is used to calculate the porosity of the rock.Another common method for measuring porosity is the water saturation method. This method involves placing a sample of rock in a container and then filling thecontainer with water. The volume of water that is absorbed by the rock is then measured, and this volume is used to calculate the porosity of the rock.Permeability can be measured using a variety of methods, including the constant head method, the falling head method, and the pulse decay method. The constant head methodinvolves measuring the flow rate of a fluid through a sample of rock under a constant pressure gradient. Thefalling head method involves measuring the time it takesfor a fluid to flow through a sample of rock under a decreasing pressure gradient. The pulse decay methodinvolves measuring the pressure response of a sample ofrock to a pulse of fluid.The porosity and permeability of rocks can vary greatly depending on the type of rock, the mineralogy of the rock, and the texture of the rock. For example, sandstonestypically have higher porosity and permeability than shales,and limestones typically have lower porosity andpermeability than sandstones.The porosity and permeability of rocks are important properties that are used to characterize the ability of rocks to store and transmit fluids. These properties are used in a variety of applications, including the evaluation of oil and gas reservoirs, the design of groundwater wells, and the remediation of contaminated aquifers.## 中文回答， ##。
