The Design And Implementation Of Weil Logging Curve Transformation System

As we all know, the process of petroleum exploration and development isconstituted by geophysical prospecting, logging, logging, testing for oil,exploration, etc. Well logging is an important link of exploration anddevelopment, and it is also the firsthand information of exploration. Therefor, itis used to be called eyes of geologists.In order to feel out the firsthand information of the production,welllogging curve stand in the breach, it is very important to analyzing lithologicalcharacter of the reservoir and determining geologic parameter such as thejudgement of oil, gas, water, and calculating porosity,saturation, permeability.But there are many methods, a number of curves make well logging curve looksa little miscellaneous, it takes much time and energy to collate. we develop thewell logging curve conversion system to improve work efficiency, to solve theparameter conversion and logical errors and so on.First of all, it will design the reservoir database, analyze and valuate theproblems such as organization model, access data requirements and theunification of standardize formula one by one; Then it will digitizing and checkthe pretreated data, build models and explain the parameters through the studyof four properties.The well logging curve conversion system aims at the diversity andcomplexity of residual oil in high water cut stage, through the use of geologicdate, well logging date and various dynamic production data, andcomprehensive use of the development, reservoir, logging and computer andmany other professional technology, it can hunt the layer with multi-residual oilin wells with special high water content, and describe the residual oildistribution of the oil-field in order to tap the potential of more residual oil andimprove the productivity of single well.The well logging curve conversion system can put scattered curves in order and further into a database, make the function of foundational dataconversion come true easily, facilitate the work of data loading in the future, andit also can examine the error of the data. It is an effective way to fit the stratumsituation of the model effectively and improve the management level of the welllogging curve. It plays an irreplaceable role in improving the managementefficiency of the curves.As the well logging curve conversion system put into use, it realizes theinterpretation and conversion of the small reservoir curves which displayparameters such as porosity,saturation, permeability and so on. After theconversion, it generate Las file format directly。This can facilitate the dataloading, correct logical error, reduce manual work hour. It works with highaccuracy, and it is easy to find what we want.
