Study And Development Of Hydrogeological Information System & Applied In Well Design

With the rapidly industrial process, the shortage of water resource,being faced by many countries and areas, has become one of conditional factorsin the development of society.How to make use of water resource properly andprotect natural enviroment have been universally concerned.GIS(GeographicInformation System) has been used in many fields with its capacity of datamanagement and space analysis.It is a tendency to realize united managementof belonging data and space data in hydrogeology. DaQing Oil Field exploited and built for more than 40 years has faced manyproblems in the management and utilization of water resource.It is time tobuild a Hydrogeological Information System(HIS) for exploiting and handlingwater resource. On the basis of the comprehensive analysis of related systemhome and abroad, we research and develop a Hydrogeological InformationSystem(HIS) on Geographic Information System(GIS) with accumulated Da QingOil Field hydrogeological data,the HIS has been designed twosub_systems(database management sub_system,modles sub_system) and fivemodules(document management, data management, graphic management, high-leveldesign and system management).The paper mainly analyses modle sub_system.This sub_system includes hydrogeological parameter calculationmodle,prediction modle and optimization modle and so on . In this paper, the main studies are as follows: 1. Settling the struction of HIS. 2. Realizing multi_source data integration in hydrogeology on the platform of SQL SERVER network data base. 3. Realizing computer graphic indication of hydrogeology data. 4. Building model sub_system which includes prediction model and optimization model. 5. Accomplishing the demand of new well(wells)design. IIUsing HIS in Da Qing Oil Field ,it realizes united management of data,andreviews data rapidly and precisely.At the same time,it calculateshydrogeological parameter and provides new well design method in certainregion. Finally, paper suggests that build new water sources in the west ofresearch areas. In a word, good results are got in this paper,which expect to providescientific basis on reasonably developing and implementing ground waterresources in DaQing Oil Field.
