Subsea X-mas tree hydraulic valve performance online monitoring and diagnostic system and method

Abstract

The invention discloses a subsea X-mas tree hydraulic valve performance online monitoring and diagnostic system, which comprises a data collecting portion and a data processing portion, wherein the data collecting portion collects hydraulic data of an underwater electronic module and / or a hydraulic supply module and / or a production control system respectively, and transmits the hydraulic data to the data processing portion; and the data processing portion stores and processes the hydraulic data, compares and analyzes the hydraulic data by combining pre-stored standard hydraulic data, and outputs detection results and diagnostic information. The invention further discloses a monitoring and diagnostic method corresponding to the subsea X-mas tree hydraulic valve performance online monitoring and diagnostic system. The subsea X-mas tree hydraulic valve performance online monitoring and diagnostic system and the subsea X-mas tree hydraulic valve performance online monitoring and diagnostic method acquire and analyze data online in real time, substantially increase the working efficiency, are not affected by situations such as harsh weather and sea conditions, and eliminate safety risk of personnel and equipment during construction operation in the prior art; and the subsea X-mas tree hydraulic valve performance online monitoring and diagnostic system is applied to monitoring and diagnosis of various kinds of underwater hydraulic valves, does not request large-scale engineering equipment and a large number of operators in operation, and can save a lot of personnel and equipment cost.

Description

technical field [0001] The invention belongs to the technical field of underwater oil and gas development, and in particular relates to a system and method for online real-time monitoring and diagnosis of hydraulic valve performance of an underwater Christmas tree based on computer data collection and analysis. Background technique [0002] The subsea tree is one of the key equipment for the development of deep water oil and gas fields. There are more than 10 hydraulic control valves installed on each subsea tree. The reliability of the valves directly affects the safe operation of deep water oil and gas fields. Therefore, in daily production operations, it is necessary to focus on whether the valves of the Christmas tree are closed and opened normally, and whether there is any hydraulic leakage. The current common practice is to use engineering ships to carry underwater robots to inspect all parts of the Christmas tree, and open and close the valves one by one to confirm wh...

Problems solved by technology

The advantage of this method is that the inspection is comprehensive and in place, but the disadvantages are also particularly prominent: (1) It takes a long time for one operation, the efficiency is low, and it cannot detect the performance of the Christmas tree valve in real time; (2) The operation of engineering ships and underwater robots is easy. Affected by bad weather and sea conditions, the detection work is affected, and even the operation is suspended; (3) There are safety risks for personnel and equipment in offshore construction operations; (4) Large-scale engineering equipment and a large number of operators are required for offshore operations, and the operating costs are high
