【摘要】：基于"優(yōu)質(zhì)源巖控藏"理論和"儲(chǔ)層甜點(diǎn)找油"思想,應(yīng)用測(cè)、錄井、試油、薄片等資料,系統(tǒng)總結(jié)松南中央坳陷區(qū)泉四段致密油的分布規(guī)律,剖析不同類(lèi)型致密砂巖油成藏的主控因素。研究表明:致密砂巖油藏集中分布在長(zhǎng)嶺凹陷內(nèi)及其周邊斜坡區(qū),具有"滿(mǎn)坳含油、宏觀(guān)連片"的特征和"東富西貧、南富北貧"的差異性;青一段下段烴源巖殘余有機(jī)碳含量(TOC)大于2.0%的優(yōu)質(zhì)源巖展布范圍控制致密油藏分布格局;異常高壓與源儲(chǔ)斷層的空間配置關(guān)系控制下部砂組含油性,剖面上油氣下排深度最大為140 m;平面上超壓大于10 MPa、與斷層距離小于2 500 m的區(qū)域是Ⅱ~Ⅳ砂組的致密油藏富集區(qū);優(yōu)質(zhì)儲(chǔ)層物性"甜點(diǎn)"控制致密油富集程度及產(chǎn)量;坳陷型湖盆上生下儲(chǔ)式致密砂巖油藏的形成主要存在凹陷區(qū)"源內(nèi)直排倒灌"和斜坡區(qū)"源邊反轉(zhuǎn)斷層遮擋"兩種成藏模式。
[Abstract]:Based on the theory of "high quality source rock and reservoir control" and the idea of "finding oil for reservoir desserts", the distribution of dense oil in the fourth member of spring in Songnan central depression is systematically summarized by applying the data of logging, logging, oil testing and thin slice. The main factors controlling the formation of different types of tight sandstone oil reservoirs are analyzed. The results show that the tight sandstone reservoirs are mainly distributed in and around the Changling sag, with the characteristics of "Man depression oil bearing, macroscopic continuous slice" and "rich in the east and poor in the west". The difference of the poor in the south and the north, the distribution of the source rock residual organic carbon (TOC) more than 2.0% in the lower member of the first member of Qinghai Province controls the distribution pattern of the tight reservoir, the relationship between the abnormal high pressure and the spatial distribution of the source reservoir fault controls the oil content of the lower sand formation. The maximum depth of oil and gas discharge on the section is 140 m, the area with overpressure more than 10 MPA and fault distance less than 2 500 m is a dense reservoir rich area of sand formation 鈪，
