0引言
鄂爾多斯盆地陜北斜坡子北地區(qū)自20世紀(jì)80年代進(jìn)行油氣勘探開(kāi)發(fā)以來(lái),已經(jīng)在中生界延長(zhǎng)組長(zhǎng)6、長(zhǎng)4+5、長(zhǎng)2段等發(fā)現(xiàn)了工業(yè)油流,其中長(zhǎng)6段為主力油層組。對(duì)子北地區(qū)長(zhǎng)6段油層組的研究,目前仍以沉積相、儲(chǔ)層特征、注水開(kāi)發(fā)工藝等為主[14]。前人開(kāi)展了較單一的沉積環(huán)境、生油巖特征、生產(chǎn)開(kāi)發(fā)、砂體發(fā)育特征等研究,但未對(duì)油氣成藏條件進(jìn)行過(guò)系統(tǒng)的深入分析。近年來(lái),隨著大規(guī)模勘探開(kāi)發(fā)工作的深入,單一油氣藏要素分析限制了對(duì)子北地區(qū)長(zhǎng)6段油藏形成條件及控制因素的全面認(rèn)識(shí),制約著該層位油藏進(jìn)一步的勘探部署。筆者在收集1 000余口鉆井資料的基礎(chǔ)上,以子北地區(qū)長(zhǎng)6段油層組的生油、儲(chǔ)層、圈閉、保存等為整體,對(duì)長(zhǎng)6段油層組油氣成藏條件進(jìn)行探討,明確油氣成藏條件及主控因素,為研究區(qū)下一步油藏勘探提供地質(zhì)依據(jù)。
1區(qū)域地質(zhì)概況
子北地區(qū)位于陜北地區(qū)子長(zhǎng)縣,主要包含澗峪岔油田和子北油田,構(gòu)造位置位于陜北斜坡帶東部(圖1),區(qū)域整體構(gòu)造為一向西傾斜的平緩單斜,坡降一般為每千米7~10 m,地層傾角小于1°。區(qū)內(nèi)不發(fā)育斷層和褶皺,但由于差異壓實(shí)作用,僅在小范圍內(nèi)形成一系列幅度較小的鼻狀隆起[5]。上三疊統(tǒng)延長(zhǎng)組沉積期是鄂爾多斯盆地沉積演化史上的重要階段,該階段盆地沉積面積最大,物源充沛,經(jīng)歷了完整的湖泊三角洲沉積演化旋回。上三疊統(tǒng)延長(zhǎng)組長(zhǎng)7、長(zhǎng)6期等有重要實(shí)際意義:長(zhǎng)7期,盆地深湖相沉積面積大,泥頁(yè)巖厚度大,為子北地區(qū)乃至全盆地油氣的生成提供了良好的物質(zhì)基礎(chǔ);長(zhǎng)6期,湖盆開(kāi)始收縮,沉積補(bǔ)償大于沉降,湖泊三角洲發(fā)育處于高峰期,多個(gè)規(guī)模較大的三角洲發(fā)育,為油氣運(yùn)移、儲(chǔ)集等提供了較好的地質(zhì)條件[68]。
2長(zhǎng)6段油藏生、儲(chǔ)、蓋條件
2.1烴源巖條件
烴源巖作為油氣生成的物質(zhì)基礎(chǔ),是評(píng)價(jià)潛在含油氣盆地的重要對(duì)象。“源控論”至今對(duì)找油依然發(fā)揮著重要的作用。鄂爾多斯盆地中生界烴源巖主要發(fā)育于三疊系延長(zhǎng)組第二、三段(長(zhǎng)9段—長(zhǎng)4+5段),主要為深湖—淺湖相沉積的暗色泥巖生油巖,尤以長(zhǎng)7段烴源巖最為發(fā)育,是鄂爾多斯盆地油氣藏形成的主要有機(jī)質(zhì)來(lái)源[917]。子北地區(qū)處于半深湖—淺湖相沉積環(huán)境,長(zhǎng)7段烴源巖厚度較薄,為3~17 m,屬于盆地長(zhǎng)7期生油巖沉積的邊緣地區(qū)[18]。通過(guò)鉆井巖芯觀察,子北地區(qū)長(zhǎng)7段烴源巖顏色較長(zhǎng)6段黑,植物化石含量較其他層段豐富,表明長(zhǎng)7段的有機(jī)質(zhì)豐度要比其他層位的烴源巖高(圖2)。為了進(jìn)一步明確長(zhǎng)7段烴源巖的有機(jī)質(zhì)豐度,本次分析采用總有機(jī)碳(TOC)、生烴潛量等常用參數(shù),根據(jù)中國(guó)陸相生油巖有機(jī)質(zhì)豐度評(píng)價(jià)標(biāo)準(zhǔn)[19](表1),對(duì)該段烴源巖有機(jī)質(zhì)豐度進(jìn)行定量分析。
研究區(qū)延長(zhǎng)組長(zhǎng)6、長(zhǎng)7段烴源巖總有機(jī)碳以大于1.0%為主,占60%,達(dá)到了主力生油巖標(biāo)準(zhǔn),但是生烴潛量較低,處于(05~2)×10-3之間的占60%,大于6×10-3的僅占30%(表2),屬于較好烴源巖。尚慧蕓等統(tǒng)計(jì)了鄂爾多斯盆地三疊系延長(zhǎng)組黑色泥頁(yè)巖的總烴(HC,552×10-6),認(rèn)為其屬于好生油巖范疇[20]。試驗(yàn)分析結(jié)果顯示:子北地區(qū)長(zhǎng)6、長(zhǎng)7段黑色泥巖熱解峰溫(Tmax)分布在436 ℃~455 ℃,平均為4421 ℃。
2.2儲(chǔ)層條件
勘探開(kāi)發(fā)實(shí)踐表明,子北地區(qū)長(zhǎng)6段油藏的儲(chǔ)層主要為分流河道砂體[22]。根據(jù)巖芯觀察和巖石薄片鑒定結(jié)果,子北地區(qū)長(zhǎng)6段砂巖主要為淺灰色、淺灰綠色的中—細(xì)粒長(zhǎng)石砂巖及巖屑長(zhǎng)石砂巖。砂巖碎屑成分以各類長(zhǎng)石(體積分?jǐn)?shù)為4732%)為主,其次為石英(27.10%)、云母(608%)和巖屑(3.50%),此外還含有少量重礦物。碎屑顆粒分選性較好,磨圓度以次棱角狀—次圓狀為主,砂巖具有中等結(jié)構(gòu)成熟度、較低礦物成熟度的特點(diǎn)[圖3(a)~(c)],表明子北地區(qū)長(zhǎng)6段儲(chǔ)層堆積的沉積物離物源較近。
子北地區(qū)長(zhǎng)6段儲(chǔ)層的孔隙類型以粒間孔為主,其次為溶蝕孔;另一方面,綠泥石、石英次生加大、碳酸鹽等膠結(jié)物的堵塞作用導(dǎo)致物性降低[圖3(d)~(f)]。子北地區(qū)長(zhǎng)6段砂巖儲(chǔ)層物性統(tǒng)計(jì)顯示:孔隙度主要分布范圍為9.0%~11.0%,滲透率主要分布范圍為(013~1.0)×10-3 μm2,變化幅度較大(圖4)。對(duì)照鄂爾多斯盆地低滲透砂巖儲(chǔ)層評(píng)價(jià)標(biāo)準(zhǔn)[23],子北地區(qū)長(zhǎng)6段儲(chǔ)層屬于超低滲透Ⅲa類儲(chǔ)層,物性條件整體較差,非均質(zhì)性較強(qiáng)。
總體上,子北地區(qū)長(zhǎng)6段儲(chǔ)層比較發(fā)育,分布范圍廣,巖性以長(zhǎng)石細(xì)砂巖為主,但是物性較差,且縱橫向變化較大??v向上,長(zhǎng)61、長(zhǎng)62段物性較好,其次為長(zhǎng)63段,長(zhǎng)64段物性則最差;平面上,巖相古地理控制了砂體的形成和分布,主要油層長(zhǎng)61段砂體厚度為10~40 m,砂體展布與區(qū)域物源供給方向一致,呈現(xiàn)NE向、NNE向條帶狀展布。在三角洲分流河道區(qū),長(zhǎng)6段儲(chǔ)層物性較好,而在河道間沉積區(qū)的物性較差。
2.3蓋層條件
根據(jù)野外露頭、鉆井、測(cè)井、試驗(yàn)分析等資料,子北地區(qū)延長(zhǎng)組主要發(fā)育以陸相碎屑沉積的泥巖、粉砂質(zhì)泥巖為主的長(zhǎng)4+5段和長(zhǎng)1段兩套泥巖蓋層。其中,長(zhǎng)4+5段發(fā)育的泥巖為下伏長(zhǎng)6段儲(chǔ)層的主力封蓋層。平面上,子北地區(qū)長(zhǎng)4+5段蓋層厚度主要集中在25~50 m,厚度大,分布廣泛,延展性好(圖5),巖性主要為泛濫平原相和沼澤相泥巖、粉砂質(zhì)泥巖、炭質(zhì)頁(yè)巖等,具有良好的封蓋性能。該蓋層對(duì)長(zhǎng)4+52、長(zhǎng)6段油層組的油氣起到很好的封隔作用,是研究區(qū)長(zhǎng)4+52、長(zhǎng)6段油氣成藏的重要控制因素之一。另外,在長(zhǎng)6段油層組內(nèi)部,沉積旋回的頂部發(fā)育有局部性蓋層,巖性主要為泥質(zhì)巖或泥巖夾粉砂巖,厚度較薄,為2~6 m,對(duì)長(zhǎng)6段各油層起到封隔作用。
3.1油藏類型
子北地區(qū)位于陜北斜坡的東部,構(gòu)造總體為一平緩的西傾單斜,傾角約為0.5°,局部存在由于差異壓實(shí)而形成的低幅度鼻狀隆起。子北地區(qū)長(zhǎng)61段油層組頂面構(gòu)造圖總體為西傾單斜,發(fā)育很小的鼻隆構(gòu)造(圖6)。各小層頂面長(zhǎng)6段油層組各小層頂面構(gòu)造具有一定的繼承性,均為西傾單斜,僅發(fā)育小的鼻隆構(gòu)造。沿長(zhǎng)6段河道伸展方向的油藏剖面圖顯示長(zhǎng)6段油氣主要儲(chǔ)存在長(zhǎng)61、長(zhǎng)62、長(zhǎng)63段河道砂體內(nèi),油藏類型主要為巖性圈閉(圖7)。
3.2.1主分流河道
主分流河道控制優(yōu)質(zhì)儲(chǔ)層發(fā)育和宏觀原油富集。子北地區(qū)長(zhǎng)6段油藏儲(chǔ)層主要為三角洲平原分流河道沉積,長(zhǎng)6段油藏儲(chǔ)層主要分布在砂體厚度較大的分流河道位置(圖8),含油層主要為長(zhǎng)61、長(zhǎng)62、長(zhǎng)63段砂層組,長(zhǎng)64段砂層組僅局部含油。分流河道砂體巖性主要為中—細(xì)粒長(zhǎng)石砂巖、巖屑長(zhǎng)石砂巖,底部多為河道滯留沉積物,與下伏地層常為侵蝕接觸,且多層砂體相互疊置,累計(jì)厚度大,側(cè)向展布寬度大,多連片,有利于油氣在其中運(yùn)移和聚集。厚度較小的分流河道砂體孤立分布,其上、下為泥質(zhì)巖隔檔,雖然有利于油氣的聚集,但連通性較差,其圈閉的石油地質(zhì)儲(chǔ)量較小。油層分布主要受分流河道砂體控制,子北地區(qū)子北油田、澗峪岔油田主要分布于分流河道中。
3.2.2儲(chǔ)層物性及其非均質(zhì)性
儲(chǔ)層物性及其非均質(zhì)性控制原油的微觀分布特征。子北地區(qū)延長(zhǎng)組各沉積體系的物源方向大致相同,為東北物源。長(zhǎng)6段油層組顆粒分選性相對(duì)要好,雜基含量較少,砂體抗壓實(shí)能力相對(duì)較強(qiáng),殘余粒間孔和各類次生溶孔、溶縫較多,儲(chǔ)層物性相對(duì)較好(圖4);長(zhǎng)6段油層組含油面積大,成為延長(zhǎng)組主力油層之一;長(zhǎng)6段油氣主要富集在物性相對(duì)較好的長(zhǎng)61、62、63段砂體內(nèi),油層分布主要受儲(chǔ)層物性的控制。
3.2.3原油分布
原油分布在一定程度上受鼻狀隆起影響。子北地區(qū)長(zhǎng)6段油藏主要為巖性圈閉,但受差異壓實(shí)作用形成的低幅度鼻狀構(gòu)造對(duì)本區(qū)長(zhǎng)6段原油分布也有一定的控制作用,主要體現(xiàn)在主力油層長(zhǎng)61段油層在鼻狀隆起部位較為富集。長(zhǎng)6段油層組發(fā)育一些低幅度的鼻狀隆起,自長(zhǎng)63段頂至長(zhǎng)61段頂,鼻狀隆起具有一定的繼承作用。
3.3油氣成藏期次
進(jìn)行測(cè)溫時(shí),選取油氣包裹體進(jìn)行均一溫度測(cè)定。顯微鏡下觀察可見(jiàn)包裹體形態(tài)不規(guī)則,大小一般為3~8 μm,氣液比一般大于8%,甚至遠(yuǎn)遠(yuǎn)高于8%,由此可識(shí)別兩期油氣包裹體分布:第1期主要呈橢圓形孤立狀,分布在亮晶方解石膠結(jié)物中,包體較小;第2期主要呈串珠狀,分布在石英晚期裂隙中,晚期裂隙切穿了顆粒邊界,油氣包裹體較大,普遍含鹽水,包裹體油、氣、水相態(tài)邊界非常清楚。測(cè)溫結(jié)果分布直方圖顯示,長(zhǎng)6段樣品包裹體均一溫度主要集中在100 ℃~110 ℃和130 ℃~140 ℃,呈雙峰狀分布(圖9)。
將包裹體均一溫度數(shù)據(jù)與地層溫度的熱演化史進(jìn)行對(duì)比,可以判定油氣成藏的時(shí)間[3943]。通過(guò)子北地區(qū)古地溫的熱演化史分析,結(jié)合包裹體測(cè)溫?cái)?shù)據(jù),子北地區(qū)在早白堊世早期(120~130 Ma)發(fā)生一次油氣充注過(guò)程,早白堊世末期(95~105 Ma)為主要聚集成藏期(圖10)。早白堊世是鄂爾多斯盆地子北地區(qū)油氣運(yùn)移并在長(zhǎng)6段油層組聚集成藏的重要時(shí)期。
勘探實(shí)踐表明,陜北地區(qū)延長(zhǎng)組油藏的形成和分布基本受延長(zhǎng)組生油凹陷的控制[11,4446]。長(zhǎng)7段油層組中部的深湖相泥巖為子北地區(qū)油氣藏的形成提供了豐富的油源物質(zhì)基礎(chǔ),形成的大量烴類物質(zhì)以“爬樓梯”的方式在早白堊世早期向上運(yùn)移充注,早白堊世晚期在長(zhǎng)6段砂體大規(guī)模聚集成藏(圖11)。長(zhǎng)6段—長(zhǎng)7段層間或?qū)觾?nèi)的粉砂巖、砂質(zhì)泥巖、泥質(zhì)粉砂巖、泥巖互層、致密砂巖等構(gòu)成良好的蓋層,為大面積聚油創(chuàng)造了較好的保存條件。
4結(jié)語(yǔ)
(1)通過(guò)對(duì)鄂爾多斯盆地子北地區(qū)長(zhǎng)6段油藏成藏條件的分析,子北地區(qū)長(zhǎng)6、長(zhǎng)7段烴源巖主要為Ⅱ2Ⅲ型較好級(jí)別烴源巖;長(zhǎng)6段砂巖儲(chǔ)層分布廣泛,連通性好,砂巖厚度大,粒間孔、溶孔發(fā)育,具有良好的儲(chǔ)集條件;長(zhǎng)4+5段廣泛發(fā)育的泥巖以及長(zhǎng)6段內(nèi)部局部泥巖可成為長(zhǎng)6段油氣藏良好的蓋層。
(2)子北地區(qū)長(zhǎng)6段油藏為巖性油藏,長(zhǎng)6段油藏生、儲(chǔ)、蓋配置關(guān)系較好,油氣分布及富集主要受沉積微相及儲(chǔ)層物性的控制。
(3)子北地區(qū)長(zhǎng)6段油氣包裹體均一溫度呈雙峰狀,分布在100 ℃~110 ℃和130 ℃~140 ℃;長(zhǎng)7段烴源巖大量生成的烴類有機(jī)物以“爬樓梯”的方式在早白堊世早期于長(zhǎng)6段中大量聚集形成長(zhǎng)6段油藏;早白堊世是鄂爾多斯盆地子北地區(qū)長(zhǎng)6段油層聚集成藏的重要時(shí)期。
