METHODS AND SYSTEMS FOR SUBTERRANEAN BORE HOLE FRACTURE SIMULATION

摘要

Apparatus and methods for simulation of bore hole fractures are disclosed. A device (100) for simulating a fracture in a subterranean formation comprises a housing (110), an inlet (102) for directing a sample fluid to the housing (110), and a first disk (202A) and a second disk (202B) positioned within the housing (110). The second disk (202B) is movable relative to the first disk (202A) to form an adjustable gap (302) between the first disk (202A) and the second disk (202B) and the sample fluid flows through the adjustable gap (302). A common collector (216) receives at least a portion of the sample fluid that flows through at least one of the first disk (202A) and the second disk (202B). The apparatus and methods are particularly suitable for testing drilling fluids, lost circulation materials or wellbore strengthening materials. The disks can be porous disk, slotted disk or solid disks in order to represent different types of subterranean formation such as sandstones or shale.
