Movable skid-mounted chemical and physical combined dirt cleaning device for oil field

Abstract

The invention discloses a movable skid-mounted chemical and physical combined dirt cleaning device for an oil field. The device comprises a cleaning box, an air compressor and a heating device, the hot water outlet of the heating device is connected with the hot water inlet of the cleaning box, the cold water inlet of the heating device is communicated with the water outlet in the bottom end of the cleaning box to form a sealed loop for heating cleaning liquid, another water outlet of the cleaning box and the outlet of a pulse generator are gathered through a circulating pump and a one-way valve and then are communicated with the inlet of a cleaned pipeline, the outlet of the cleaned pipeline is connected into the cleaning box through a one-way valve, the air compressor is connected with the inlet of the pulse generator through an electromagnetic valve, and a power distribution cabinet is connected with the air compressor, the heating device, the circulating pump and the electromagnetic valve respectively. The device achieves combination of physical dirt cleaning and chemical dirt cleaning, some indissolvable dirt and dirt of complex pipelines can be removed by combining physical dirt cleaning and chemical dirt cleaning, multiple functions and multiple selections are achieved, high-efficiency work is achieved, and the cleaning effect of the integrated cleaning device is more outstanding compared with single chemical cleaning or single physical cleaning.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning, and relates to the cleaning of fouling and clogging of complex oil and gas pipelines, in particular to a mobile skid-mounted chemical-physical combination cleaning device for oil fields. Background technique [0002] In oilfield development, the ground gathering and transportation facilities undertake the function of heating, separation and transportation. The gathering and transportation equipment and processes are diversified, and there are scales caused by changes in temperature and pressure, and scaling caused by incompatibility of fluid components. Scaling can lead to damage to equipment pipelines. With the increase of energy consumption, the fluid cannot be transported, the production is stopped, the economic loss is large, and the production efficiency is low. Therefore, cleaning and anti-scaling is a very important task. [0003] Scale cleaning technology, the current developm...

Problems solved by technology

The heating furnace oil delivery pump and metering tubes that were originally built separately in the metering station were integrated to simplify the layout of the station. However, the complexity of the device is concentrated in the fact that the heating coil has 36 turns, and the pipe diameter is usually ф89*4. After heating Pressurized transportation of water-containing crude oil, due to the complex composition of water-containing crude oil in each single well, the scaling is very serious through mixing and heating conditions, and the scale type is complex and changeable. The existing scale cleaning technology cannot solve such complex pipeline scale cleaning problems. The method cannot dissolve the barium and strontium scale, and the simple physical pig is easy to get stuck, which is not safe. The simple air pulse is not easy to clean the hard scale, and the effect is poor.

At the same time, the complex and scattered topography of the oil field is not suitable for fixed scale cleaning devices, because its movement remains unchanged, requiring huge manpower and material resources
