Description

Technical Field

[0001] The invention relates to the technical field of drilling cuttings processing, in particular to a device for feeding a drilling cuttings mixture subjected to thermal desorption treatment and a method for using the device. Background Art

[0002] During the drilling process of shale gas exploration and production, drilling fluid needs to be injected to lubricate and cool the drill bit, build a wall to prevent leakage, and carry rock fragments back to the ground. The rock fragments returned to the ground are drilling cuttings. Drilling cuttings belong to a multiphase system, generally composed of oil in water (O / W), water in oil (W / O) and a large amount of suspended solids. The viscosity is relatively high, and the solid phase is difficult to completely precipitate. Drilling cuttings generally have an oil content of 5-20% and a water content of 10-20%. They are mostly composed of diesel, water, asphalt, drill cuttings, polymer compounds, and other impurities, and are in a viscous and wet state.

[0003] At present, the processing of drilling cuttings generally adopts the thermal desorption process, which requires that the standard of drilling cuttings entering the thermal desorption device is a liquid content of ≤30%. If the liquid content of the collected drilling cuttings is >30%, it is necessary to mix the dry material and the mixed material so that the standard of the drilling cuttings material is a liquid content of ≤30%.

[0004] The existing mixing of dry and wet materials is mostly done by taking the measured drilling cuttings from the wet material storage tank and the dry material storage area to the mixing area by a vehicle, and then the excavator mixes the materials until the liquid content reaches ≤30% before transferring them to the loader. In this way, the mixing efficiency of dry and wet materials is low and the mixing time is long.
