The slurry solidification treatment scheme of the oilfield is as a whole that drilling cuttings waste, lime and cement are collected through the hopper, and then transferred to the stirring solidification device to dry the drilling cuttings after full mixing. Firstly, the original high water content drilling cuttings waste is input into the drilling cuttings collection hopper, and the BWLXNJ-7.5 (7.5KW) screw under the drilling cuttings collection hopper is used. The rotary conveyor conveys the original drilling cuttings to the plough-knife solidification device for mixing. While the drilling cuttings waste is conveyed, the lime and cement in the lime hopper and cement hopper are conveyed to the plough-knife solidification device through BWLXSH-3 (3KW) screw conveyor and BWLXSN-3 (3KW) screw conveyor分别混合。通过调整年代peed ratio of the PLC control cabinet, the screw conveyors can be fed quantitatively. After the three spiral conveyors are fully stirred and dried in the plough knife curing device, they are discharged regularly from the outlet of the plough knife curing device through the setting of PLC. The mixing and mixing work is finished, thus realizing the purpose of solidifying drill debris.
Oil and natural gas exploration and development process will produce a large number of pollutants, waste drilling mud is one of the main pollutants. If not handled properly, it will inevitably pollute the local environment and cause incalculable losses, and environmental pollution in turn will restrict the development of the petroleum industry. According to the field application of oil field mud solidification treatment scheme, Zhengdao Energy provides a set of optimized mud solidification treatment scheme for oil field drilling construction units to help understand.
