鄂尔多斯盆地含煤储层增产技术研究与应用

Research on Technology of Coal-bearing Reservoir Stimulations in Ordos Basin and Its Application

针对鄂尔多斯盆地太原组砂岩储层普遍含有煤层、压裂增产难度大的现状,开展了含煤储层增产技术研究。根据储层与煤层不同组合类型,提出了相应的改造措施,并取得了一定的增产效果,初步解决了含煤储层有效改造的难题,为同类气田的增产提供了有效途径。

For the current situation of containing coal seam generally and difficulties in fracturing stimulation in Ordos Basin Taiyuan sandstone reservoirs, carried out the research on technology of coal-bearing reservoir stimulations. According to different combinations of types of reservoirs and coal seams, proposed corresponding transformation measures, which achieved effect of stimulations, solved the problems of effective transformation of the coal-bearing reservoir initially, providing an effective way for stimulations of similar gas field.
