Title:
RESEARCH AND TEST SYSTEM FOR INFLUENCING FACTORS OF ROCK BREAKING AND CUTTINGS REMOVAL EFFICIENCY OF DRILLING VERTICAL SHAFT ROLLER CUTTER
Document Type and Number:
WIPO Patent Application WO/2023/193820
Kind Code:
A1
Abstract:
A research and test system for influencing factors of rock breaking and cuttings removal efficiency of a drilling vertical shaft roller cutter (41), which comprises a spare tank (1), a rock breaking and cuttings removal apparatus, a mud-cuttings separation apparatus, a metering apparatus, a monitoring assembly, and a control apparatus, wherein the spare tank (1) is connected to the rock breaking and cuttings removal apparatus by means of a mud conveying pipe (11); the rock breaking and cuttings removal apparatus is connected to the mud-cuttings separation apparatus by means of an outer cuttings removal pipe (20), and rock cuttings liquid produced by the rock breaking and cuttings removal apparatus is conveyed into the mud-cuttings separation apparatus by means of the outer cuttings removal pipe (20); the rock cuttings can be dried and weighed by means of the metering apparatus; and the monitoring assembly is connected to the control apparatus. By means of the test system, research can be performed on the effects on the rock breaking and cuttings removal efficiency of the drilling vertical shaft roller cutter (41) caused by the position of a cuttings removal opening (71), an optimized configuration of cutter spacing of the roller cutter (41), the rotational speed of the roller cutter (41), the rotational speed of a cutter head (37), weight on bit, mechanical parameters, selection of the type of roller cutter (41), and mud performance parameters configured for different lithographies, and said system can improve the rock breaking and cuttings removal efficiency.
