Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
As shown in Figure 1, the invention provides a kind of marine oil and gas fracturing work aid decision-making system, this system includes pressure
Split job state monitoring modular, slip condition database, attribute loop module, characteristic extracting module, ocean pressure break aid decision knowledge
Storehouse, Decision Inference module and aid decision output module；
Fracturing work state monitoring module is to the fracturing work system of marine oil and gas fracturing work ship and ship platform system
State monitor in real time, obtain its state parameter and fault alarm information；
Slip condition database is made up of SQL database software and database server, derives from data storage for storage and is
The data messages such as the frac system of system and the state parameter of marine system, fault alarm.Slip condition database system uses increment type
All of data, according to the clock flag of packet, are carried out irredundant storage by storage mode.Use data base to all numbers
According to storing and managing, it is simple to the inquiry of data, call and analyze, simultaneously facilitate inquiry and the access of Decision Inference module.
Attribute loop module is for the attribute of simplified system status data；Fracturing outside operating system and ship platform system
In system state data be made up of multiple attributes, system state data has higher dimension.High dimensional data can not direct quilt
Ocean fracturing work aid decision knowledge base uses, can not be input to reasoning module is carried out the search of aid decision scheme and
Select.Although system state data attribute is many, but the attribute of majority is all dependent attributes, does not rises during system state table is levied
Pivotal role, is only determined by the determinant attribute of minority.Use rough set theory that the redundant attributes of status data is carried out yojan,
Effectively reduce the dimension of system state data, do further feature extraction for status data and prepare.
The characteristic extracting module data to crossing through attribute loop resume module carry out feature extraction, make data have succinctly
Data form, in order to be input to pressure break aid decision knowledge base is carried out the selection of decision rules, be also convenient for by reasoning simultaneously
Module is used；Attribute reduction module carries out the yojan of attribute to initial condition data, reduces ocean fracturing work system shape
The dimension of state data.But still comparing many through the attribute of the status data of attribute reduction, the state characteristic of a system leads to
It is often to be characterized by one or several key property, it is therefore desirable to the status data after processing is carried out at feature extraction
Reason.Using principal component analytical method that status data is carried out feature extraction process, the status data after process has succinct number
According to form, it is simple to the map analysis between state feature and decision scheme.It is auxiliary that state feature after process is input to fracturing work
Help the selection carrying out match decision rule in decision knowledge base, be also inputted in Decision Inference module carry out decision scheme simultaneously
Reasoning and selection.

Ocean fracturing work association area data exchanges with the expert in fracturing work field, ocean or by machine learning, computer
The modes such as simulation modeling obtain.The acquisition process of knowledge is a process the most complicated, is not a simple knowledge individual event
Pile up.The foundation of knowledge base not only will have abundant handle the experience of ocean fracturing work expert of manager, knowledge is known
Knowledgeization and systematization, also need to the emulation be correlated with and in kind or Hardware-in-loop Simulation Experimentation simultaneously.Then mathematical model is passed through
Emulation, and the mode of programming language is programmed in knowledge base, modifies knowledge base according to test result, thus
Realize being gradually increased of knowledge base knowledge.
Ocean fracturing work aid decision knowledge base uses production rule to build, and has higher real-time and standard
Really property, improves ocean fracturing work efficiency.
Decision Inference module is equivalent to the brain of ocean fracturing work expert, and it determines to take which type of fracturing work certainly
Plan scheme goes to handle fracturing unit and ship platform；Decision Inference module will process after system mode real time data be stored in
Decision rules in aid decision knowledge base is mated, and the decision rules that reasoning module obtains exports aid decision output
In module；In the fracturing work aid decision knowledge base of ocean, storage is substantial amounts of fracturing work DECISION KNOWLEDGE, and Decision Inference
Module is equivalent to the brain of ocean fracturing work expert, and it determines to take which type of fracturing work decision scheme to go to handle pressure
Split equipment and ship platform.Decision Inference method is input to ocean fracturing work aid decision knowledge base by Decision Inference module
In, guide knowledge base to carry out the match selection of aid decision scheme according to the status information after feature extraction.According to ocean pressure break
The real-time status data of operation, can search out a plurality of decision-making that can match from the pressure break aid decision knowledge base of ocean
Scheme, but multiple decision scheme also exists and feasible even there is also infeasible situation, and at actual operation process
In also need to from multiple feasible programs, select best decision-making and perform.
Decision Inference module uses Rete reasoning algorithm to carry out optimal decision side in the pressure break aid decision knowledge base of ocean
The selection of case, it is possible to export decision scheme from huge aid decision knowledge base, successfully manage ocean fracturing work
Dynamically situation of change, promotes fracturing work operation safe efficiently.
Aid decision output module is aid decision-making system and marine oil and gas fracturing work Complex Control Center operator
Interactive interface, by aid decision output module, aid decision scheme is exported in display interface, operator are with reference to defeated
The decision scheme gone out comprehensively is analyzed, and combines practical experience and make final decision-making.
