子长油田坪庄区长9油层勘探实践与认识

Exploration of Chang 9 Oil Layer in Pingzhuang Area of Zichang Oilfield

子长油田坪庄区位于鄂尔多斯盆地东部,目前已完钻下组合探井5口,长9油层均有油气显示,但常规压裂试油效果差。通过区域地质研究、储层认识,分析认为该区长9属于典型的特低孔、特低渗储层,引用体积压裂储层改造技术,取得了良好的试油效果,为下一步勘探提供新的思路。

The Pingzhuang area of Zichang oilfield is located in the eastern part of Ordos Basin. At present,5 combined exploration Wells have been drilled, and oil and gas are shown in all the chang 9 oil layers,but the conventional fracturing test results are poor.Through regional geological research and reservoir understanding,the analysis shows that chang 9 in this area belongs to the typical ultra-low porosity and ultra-low permeability reservoir.By using the technology of volume fracturing reservoir reconstruction, good oil test results have been achieved, providing new ideas for the next exploration.
