Example Embodiment

[0035] Example one

[0036] This embodiment takes the accounting of a certain underwater production system equipment as an example to further introduce the method of the present invention.

[0037] 1) The structure of the underwater production system is divided into five basic module units: manifold module 1, Christmas tree module 2, control distribution module 3, riser module 4 and tee module 5. Typical subsystem types are divided into production fluid system, Glycol system and underwater control system;

[0038] 2) Split the underwater production system to be calculated to obtain typical subsystems that can be combined into the underwater production system to be calculated and other types of equipment that are not typical subsystems;

[0039] 3) Respectively calculate the types and quantities of the typical subsystems and other equipment not belonging to the typical subsystems obtained in step 2) to obtain the equipment quantity of the underwater production system to be calculated; ...

Abstract

The invention relates to a subsea production system device quantity rapid accounting method, comprising the following steps of 1), analyzing arrangement modes and function types of an subsea production system, thereby obtaining different kinds of typical subsystems required for establishing the subsea production system, wherein the typical subsystems are composed of a plurality of basic module units; 2), splitting a to-be-accounted subsea production system, thereby obtaining device categories capable of being combined to form the typical subsystems of the to-be-accounted subsea production system and the other device categories which do not belong to the typical subsystems; and 3), accounting the device categories and quantity of the typical subsystems and the other device categories and quantity which do not belong to the typical subsystems obtained in the 2), thereby obtaining the device quantity of the to-be-accounted subsea production system. The method can be widely applied to subsea device quantity rapid accounting of preliminary study of the subsea production system.

Description

Technical field [0001] The invention relates to a method for improving the accounting efficiency of underwater production system equipment, in particular to a rapid accounting method for the number of underwater production system equipment. Background technique [0002] In the preliminary research of the underwater production system, one of the main tasks of the underwater machinery major is to calculate the list of underwater production system equipment in multiple plans, so that the subsequent economic major can be used for the comparison and selection of large plans and the calculation of economic benefits of gas fields. [0003] At present, in the calculation of the equipment list for the preliminary research of the underwater production system, the number of equipment in the underwater production system in each scheme is often counted according to the general plan of the scheme. When it comes to the calculation of the preliminary equipment list of the complex underwater product...
