Subsea christmas tree tubing hanger cleaning tool

Abstract

The invention discloses a subsea christmas tree tubing hanger cleaning tool. The cleaning tool comprises a driving assembly, an inner wall cleaning brush head, a high-pressure water spraying device, asewage collector and a sewage drainage pipe; the driving assembly comprises an operating lever and a power device connecting the operating lever, and the high-pressure water spraying device comprisesa high-pressure water spraying pipe and a high-pressure water spraying driving device. The power device drives the operating lever to move vertically or rotate so as to drive the inner wall cleaningbrush head sleeving a side wall of the bottom of the operating lever to move vertically or rotate, thereby cleaning an inner wall of a tubing hanger. Combined with the high-pressure water spraying pipe sleeved in the operating lever and protruding from the bottom of the operating lever, water is sprayed to clean the dirt on the inner wall of the tubing hanger, the dirty water or dirt is retained by the sewage collector connected to the bottom of the tubing hanger, and the dirty water or dirt is pumped away through the sewage drainage pipe. According to the cleaning tool, the operation mode ofon-site well head subsea tubing hanger cleaning is achieved, and secondary pollution and surrounding seawater environmental pollution due to the fact that the dirt falls into the well can be prevented.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a cleaning tool for an underwater Christmas tree tubing hanger. Background technique [0002] With the over-exploitation of oil on land, it has been depleted. At present, the development of oil and gas has been transferred from the land to the seabed. Since the oil and gas production equipment has been working on the seabed for a long time, the working conditions of the seabed and sea water have a strong impact on the oil and gas production equipment. The corrosive effect of the oil (gas) equipment puts forward very high requirements, which also makes the equipment very expensive. In order to save production costs, we need to maintain the subsea equipment frequently. Since the equipment works under the sea, it is also more difficult and troublesome to maintain. This requires a tool that is simple and easy to operate. [0003] The Christmas tree is a wellhead device u...
