Description

Technical Field

[0001] This utility model relates to the field of oil and gas production technology, and in particular to a fully automated intelligent crude oil detection device for unmanned platforms in offshore oil fields. Background Technology

[0002] Currently, the most common testing item on unmanned platforms in offshore oilfields is the detection of crude oil water content. The testing equipment used includes centrifuges and other instruments. The current method for crude oil testing on unmanned platforms involves taking samples from oil and water wells and subsea pipelines during planned visits, equipment inspections, or maintenance, according to testing requirements. These samples are then tested and recorded upon return to the supporting facility. This current method suffers from significant data delays, hindering timely production adjustments. Production management requires timely monitoring of water content changes in oil wells (new well commissioning, production system adjustments, and significant water content changes detected by MFM). This process necessitates manual intervention, increasing the number of times personnel must visit the unmanned platform. In adverse weather conditions, access to the unmanned platform is impossible, preventing the collection of test data and resulting in a lack of reference data for oil well production systems, impacting well yields. Furthermore, the manual pretreatment process for sample testing is cumbersome and time-consuming, and the exposure to toxic and harmful chemicals during testing poses a health risk to operators.
