摘要
The problems related to the use of DST tests in works related to hydrocarbon deposits exploration and development are addressed in the paper. The possibility of using results of tests to designing DST technology in recognized deposits, and undertaking technological decisions in the development process are presented on the example of Upper Jurassic-Lower Cretaceous strata of the Carpathian Foredeep. At the stage of designing, the following elements were planned to be taken into account in the DST technology: results of well logs, statistical predictions of reservoir conditions and technological parameters as well as results of technological check-ups of the test itself, applied interpretation methods and processing of obtained results. The possibility of using information obtained from interpretation of DST tests for hydrocarbon deposits recognition was considered. On this basis the main technological parameters can be determined and detailed reservoir diagnostics made on the basis of analysis and interpretation of DST results with traditional Horner method and new log-log method, depending on the quality of the obtained pressure logs. A method of using statistical data from DST tests for designing successive tests was presented on the example of the Upper Jurassic Lower Cretaceous strata in the Carpathian Foredeep. The analysis of the block, diagrams revealed that a thorough study of the DST technology may increase the quality and completeness of the results and enable undertaking efficient technological decisions about the development of deposits and evaluating productivity of the analyzed strata.
