| 摘要: |
| 本文对萨尔图油田中部葡萄花油层组的非均质性进行定量半定量研究,认为葡萄花油层组PⅠ2小层层内非均质性最严重,与沉积微相密切相关;单砂层垂向上渗透率的变化以正韵律和复合式韵律为主,局部发育反韵律模式;层内非均质性强弱依次为PⅠ2a、PⅠ3、PⅠ2b、PⅠ1、PⅠ4;层间非均质性在PⅠ3和PⅠ4间表现得最强,其它相对要弱;各小层平面非均质性相差无几,整体表现为较强的非均质性。 |

| Abstract: |
| The reservoir heterogeneity tends to exert an important effect on the oil and gas exploration. The quantitative and semi-quantitative analysis of the heterogeneity of the Putaohua oil reservoirs in the Daqing Oil Field indicates that the intrastratal heterogeneity is very poor in the PI2 bed in the Putaohua oil reservoirs, and closely related to sedimentary microfacies. Vertically, the distribution of the permeability displays the variations of positive and compound rhythmicity with local reversed rhythmicity. There are gradations in intrastratal heterogeneity degree from PI2a through PI3 to PI2b, PI1 and finally to PI4. The interstratal heterogeneity is strongest at the boundary between the PI3 and PI4 beds in the Putaohua oil reservoirs. Laterally, the heterogeneity is relatively stronger on the whole in the Putaohua oil reservoirs. |
