Research And Implementation Of Measurement While Drilling Model In Steering Mud Logging System

The figure of MWD is the combination of well logging and geological information, qualitative and quantitative description of each parameter in the well drilling process, lithology and reservoir segment characteristics. It can help reservoir survey engineer quickly and accurately understand and grasp the distribution of various parameters in order to carry out a comprehensive evaluation of the reservoir and make accurate decisions. Use the computer to draw the curve of various parameters, can be more intuitive to show the data in front of the oil workers, and freed from the tedious work of drawing, so that they are more focused on oil exploration data analysis and interpretation.In the implementation process, mainly on the following three aspects were studied:1. Construct the frame of measurement while drilling moduleUnderstand the overall framework structure of the logging-oriented system, as well as the communication process between the various structural, primarily through the presentation layer, business logic, data access layer three levels of in-depth analysis, understanding of the framework structure, clear MWD module of reasonable, and software reusability, scalability and flexibility to design a class structure.2. Study the module involves correlation algorithmAccording to module’s operating environment and corresponding function, give a research on related to the algorithm, containing the algorithm that changes the relevant data of each parameter into the vertical and horizontal coordinates of the output device, discrete algorithms of data points, well depth is converted to vertical depth of the algorithm, as well as curves, explain the conclusions and lithology of the rendering algorithm.3. Additional tools of this moduleThe annotation tool:This tool is mainly completed to indicate function of the curve on the image to explain. Use it to record and compare the value of the different parameters at different depths. Step tool:used to set the interval of vertical depth corresponding to a well depth.In this paper, the realization of logging-oriented MWD Figure test had already been within the project team and professional oil drilling companies, Validation of the correctness of all the algorithms and reservoir modeling, in the design of class used large methods of design mode. The program has a high efficiency, good reusability, maintainability, and scalability. Put into use can provide an intuitive and accurate guidance for drilling.
