"碎屑岩储集层" can be translated into English as "clastic reservoir rock" or "clastic reservoir".
"Clastic" refers to rocks composed of fragments (clasts) of pre-existing minerals or rocks, which is a characteristic feature of clastic rocks.
"Reservoir" in this context denotes a geological formation that can store and transmit fluids such as oil, gas, or water, making it a crucial component in petroleum geology.
Both terms are commonly used in the field of petroleum geology and engineering to describe such geological formations.
