The technique of fan characterization in Jilin oilfield reveals reserves benefit area
China oil network news in September 7th, Jilin Oilfield by characterizing the application of new technology of fan, has completed the test in 3 wells are high yield oil more than 30 cubic meters of flow, confirmed the benefits of the development potential and expanding potential of Liang Jia tectonic belt.
The Liang Jia tectonic belt is affected by regional geological conditions. The faults are developed, the velocity changes vertically and horizontally, the structure is difficult to implement and the reservoir changes rapidly. Jilin oilfield to take appropriate technical measures, deepening the complex block structure interpretation technology, and the implementation of fault structure, at the same time to carry out geological model under the guidance of the fan body description and reservoir prediction technology research and implementation of vertical distribution of target layer.
By deepening the fan body characterization technology, researchers using seismic sedimentology research, multi attribute analysis and the inversion technique, the implementation of the macro distribution of fan and fan sand body inside the main target layer stacked relationship; optimization of well seismic calibration, fine comprehensive fault detection technology and full 3D structural interpretation complex fault block interpretation technique, the fine implementation of target top structure form, the relationship between reservoir and hydrocarbon enrichment law of tectonic evolution and hydrocarbon.
The development and application of geophysical prospecting technology provides strong support for the development and construction of new blocks and new targets in Yitong basin.
