【摘要】：精細評價的方法主要體現在精細分類和縱向細分層2個方面。通過沉積及砂體特征的精細研究,利用恒速壓汞、高壓壓汞以及納米微觀分析等手段綜合研究,認為扶余油層致密儲層可以劃分為2大類3小類,即Ⅰ-1,Ⅰ-2和Ⅱ類,其中致密油儲層與常規(guī)儲層的分界物性為孔隙度12%,滲透率1×10~(-3)μm~2,孔喉半徑為350 nm;其余Ⅰ-1和Ⅰ-2類以及Ⅰ-2和Ⅱ類物性標準分別以孔隙度10%和8%,滲透率0.25×10~(-3)μm~2和0.1×10~(-3)μm~2為界,對應的孔喉半徑分別為150 nm和75 nm。通過縱向細分層精細12分的砂層組級研究,每一層砂層組內僅含有1~2個砂體,I類致密油集中發(fā)育在FⅠ2-1,FⅠ3-1以及FⅡ2-2砂層組。在分層落實不同類型致密油剩余資源后,通過致密油水平井鉆探及大規(guī)模體積壓裂,可以有效開發(fā)致密油資源。
[Abstract]:The methods of fine evaluation are mainly reflected in fine classification and longitudinal subdivision. Based on the detailed study of sediment and sand body characteristics, and by means of constant velocity mercury pressure, high pressure mercury injection and nano micro analysis, it is concluded that the dense reservoir of Fuyu reservoir can be divided into 2 categories and 3 subclasses, I. e. I-1, I-2 and II. The boundary physical properties of tight oil reservoir and conventional reservoir are porosity 12, permeability 1 脳 10 ~ (-3) 渭 m ~ (-2) and throat radius 350 nm, the other physical property standards of 鈪，
