孔隙结构研究是油藏精细描述、储层综合评价的主要内容.本文用铸体薄片、扫描电镜、高压压汞等方法,对鄂尔多斯盆地黄陵地区长6储层的孔隙结构进行研究.发现高孔低渗是该区块储层的特征,油气的主要储集空间是中孔和小孔,渗流的基本通道是细喉和中喉.该区储层的孔喉分布复杂,使油井产能差异较大,是影响油井产能的重要因素之一.
孔隙結構研究是油藏精細描述、儲層綜閤評價的主要內容.本文用鑄體薄片、掃描電鏡、高壓壓汞等方法,對鄂爾多斯盆地黃陵地區長6儲層的孔隙結構進行研究.髮現高孔低滲是該區塊儲層的特徵,油氣的主要儲集空間是中孔和小孔,滲流的基本通道是細喉和中喉.該區儲層的孔喉分佈複雜,使油井產能差異較大,是影響油井產能的重要因素之一.

The pore structure is surveyed in fine reservoir description,reservoir comprehensive evaluation. This paper describes the pore structure of Chang-6 reservoir in Ordos Basin with the help of casting thin section,high pressure mercury and scanning electron microscopy. It shows that the reservoir features high porosity and low permeability. The oil and gas accumulation is in the mid and small holes. The seepage basic channel is fine and mid throat. The output of different wells vary thanks to the complex pore throat distribution in this reservoir.
