Offshore oil platform cabin tank circulating stirring flushing method and stirring flushing system thereof

Abstract

The invention discloses an offshore oil platform cabin tank circulating stirring flushing method and a stirring flushing system of the offshore oil platform cabin tank circulating stirring flushing method. The offshore oil platform cabin tank circulating stirring flushing method and the stirring flushing system are used in the cleaning and stirring construction of an offshore oil platform cabin tank. The cabin tank, a power pump and a manifold valve set in an offshore oil platform are utilized and connected with a hydraulic jet stirring and cleaning device arranged in the cabin tank through water pipelines to form the stirring flushing system. Each cabin tank outlet gate is connected with a flushing gate in parallel, a stirring flushing gate and a stirring flushing pipeline are additionally arranged on the manifold valve set, the flushing gates of the cabin tank are connected with the hydraulic jet stirring cleaning device fixedly arranged in the cabin tank, and a stirring cleaning loop is formed. Outlet gates, the flushing gates and the manifold valve set are inverted and replaced, and stirring and cleaning work is implemented. The system is good in use effect, a cabin cleaning effect is ideal, meanwhile, the storage condition of workover fluid is improved, and no deposit exists in the cabin at ordinary times. The method and the system have the advantages of protecting the environment, saving energy, reducing consumption and achieving cleaner production.

Description

technical field [0001] The invention belongs to cleaning and stirring equipment for offshore oil platforms, in particular to a circulating stirring and flushing method for tanks of offshore oil platforms and a stirring and flushing system thereof, which are used in cleaning and stirring construction of tanks on offshore oil platforms. Background technique [0002] When the tanks on the offshore oil platform meet the following conditions, they need to be stirred and cleaned: [0003] 1. When the wells on the platform are being washed or sand washed, chemical raw materials should be added to the workover fluid, and the chemical raw materials need to be stirred in the workover fluid tank; [0004] 2. When tanks such as workover liquid tanks, downhole sewage tanks, and mud tanks of the platform are used for a long time, a lot of mud and sand and sediments of chemical raw materials will be deposited in the tanks, and the tanks need to be stirred and cleaned. [0005] The stirrin...

Problems solved by technology

First drain the water in the tank, and then use buckets, ropes, and people to lift the cleaned dirt and sewage out of the tank and load it into a sewage tank or a sewage tank, which requires a lot of manpower and material resources. Also pollute the platform environment and marine environment

[0007] Both of the above two methods have their own disadvantages, and they cannot be well stirred and cleaned, especially when the space of some tanks is small, and the arrangement of cleaning devices and manual cleaning cannot effectively complete the cleaning and mixing of the tanks.
