Embodiment 1

[0085] The oil-containing solid pollutants produced by the oil-based mud drilling project in a shale gas block in Chongqing are mainly waste oil-based drilling fluids. The waste oil-based drilling fluids are treated according to the method and device of the present invention. The specific operation process and effects are described as follows:

[0086] 1. Implementation process

[0087] Implement with reference to the method of the present invention, specifically as follows:

[0088] In this embodiment, the heating gas medium is air, so the gas heating method is an air duct electric heater; the material transportation is a screw conveyor.

[0089] 1) Air is pumped in by the blast system and heating system (200m 3 / h) and heated to 160°C, mixed with oil-based cuttings (feed rate 50kg / h, oil content ≤ 5% after centrifugal drying) conveyed by the conveying device, and then enter the cyclone group for deep drilling Degreasing treatment. A sampling port is provided at the underf...

Abstract

The invention relates to the field of an onshore oil gas field oil-containing solid pollutant lift-off circulating method and device, and provides the onshore oil gas field oil-containing solid pollutant lift-off circulating method. The method comprises the following steps of (A) tertiary solid control, (B) centrifuge spin-drying, (C) vortex rotation for deoiling, (D) oil-water-gas heterogeneous separation and (E) gas purification. The invention further provides the onshore oil gas field oil-containing solid pollutant lift-off circulating device.

Description

technical field [0001] The disclosure belongs to the technical field of treatment of oily solid waste produced in the petroleum industry, and in particular relates to a method and device for circulating oily solid pollutants in onshore oil and gas fields without falling to the ground. Specifically, the present disclosure provides a method and device for circulating oily solid pollutants in onshore oil and gas fields without landing. Background technique [0002] All aspects of the petroleum industry, including petroleum exploration, storage and transportation, refining and chemical industry will generate a large amount of oily solid waste. Among them, oily solid waste is mainly produced in the process of oil extraction, refining and chemical industry. The third and horizontal sections of oil drilling are usually more than 1500m long, producing a large amount of oily cuttings (the production volume of a single well is about 250-500m 3 ). The oil content of oily cuttings is...
