Construction And Application Of Entry Well Fluid Database

Reservoir protection is one of the important means to maximize the use of limited oil and gas resources while entry well fluid is an essential part of the reservoir protection technology.For a long time,the study of entry well fluid has accumulated massive data and experience for different reservoirs and various surroundings basing on all kinds of experiments.However,there still exists many problems about those entry well fluid data,such as the inconvenient form of document reports to store and manage experimental data,the difficulty in data acquisition because of the lack of standard to manage those massive data and also the impossibility to realize horizontal and vertical query constraining to the single well and its horizon.In view of this situation,it is crucial to establish a complete management rule of entry well fluid data to realize the efficient sharing and intelligent management of oilfield data through information means.The main contents are as follows:(1)Based on the analysis of the process of entry well fluid and the investigation of field data,the classification standard and data specification of entry well fluid data are established.(2)Considering the inconformity of data field in different research units,this thesis actually presents a new dynamic table management by combining table field management and dynamic table management techniques.This thesis realizes the dynamic change of the extended table field by using the storage method as the row.And by managing the basic information of the table field,also realizes the field display of the dynamic table,the field type control and the field data control to solve the same table with different structure management problems.(3)In order to improve the efficiency of entry well fluid research,this thesis uses the K-Means algorithm to cluster the existing data.Based on the similarity degree of the eigenvalues in the clustering results,the weights of the eigenvalues are determined,the model library is constructed and the formula recommended algorithm are designed on the formula similarity comparison,which makes the formula study more efficient and reasonable.(4)Based on Spring + SpringMVC + Mybatis technology,the entry well fluid database management system is developed.This thesis realizes the standardized storage and management of the entry well fluid data,which could provide comprehensive support for data sharing and reservoir prediction.
