Abstract

The invention relates to the technical field of petroleum equipment, in particular to an efficient mixing system for well cementing operation. The efficient mixing system comprises a measuring tank, aclear water manifold assembly, a cement grey feeding manifold assembly, high-energy mixers, a mud mixing tank and a mud manifold assembly. The mud mixing tank is at least connected with two high-energy mixers, and an inlet of the mud mixing tank is connected with diffusion boxes which are connected with the high-energy mixers. Discharged materials of the high-energy mixers are guided into the mudmixing tank through the diffusion boxes, and the at least one diffusion box is connected with a density control system. The multiple sets of mixers are integrated, and the large-discharge-capacity and efficient mixing effect can be achieved with existing operation conditions.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a mixing system for high-efficiency well cementing operations. Background technique [0002] According to reports, the drilling cycle of the oil field industry has been reduced from 175 days to about half of 75 days; while the US shale gas has increased efficiency by 40% since 2013. With the improvement of the operating efficiency of the oilfield industry, the emergence of ultra-deep wells and the increase of the distance of solidified casing, for example, the horizontal section can only be 1000 meters in the past, and the buried depth can only be 2500 meters. Now the horizontal section can be 2500 meters. meters, and the buried depth increased to more than 4,300 meters. Such operations also put forward higher and higher requirements for large-volume cementing operations. On the other hand, due to the limitation of on-site operating conditions, such as the quality of...
