0引言
中國低孔低滲油氣資源分布廣、儲量大,在油氣勘探和開發(fā)中占據(jù)十分重要的地位[1]。目前,對低孔低滲和致密儲層等非常規(guī)油藏的勘探與開發(fā)引起了眾多學(xué)者的密切關(guān)注[212],前人建立了低孔低滲儲層孔隙度定量演化模型[13],指出儲層低滲特征具有沉積作用主控、壓實作用主導(dǎo)、溶蝕作用改善、膠結(jié)作用強化的特征[14]。
低滲儲層概念最早出現(xiàn)于20世紀三四十年代的科技文獻中,至今尚無統(tǒng)一定義。大多數(shù)研究者依據(jù)實際的地質(zhì)情況及技術(shù)水平,將低滲儲層的物性下限定為1×10-3 μm2[15],認為沉積作用、成巖作用和構(gòu)造作用是低滲儲層形成的主控因素,比如早期快速的壓實作用、中期石英次生加大和碳酸鹽膠結(jié)作用以及后期微弱的溶蝕作用形成了低孔低滲儲層[2,1519]。
中國東部中—新生代發(fā)育陸相斷陷湖盆,這類湖盆的陡坡帶因具有坡度陡、物源近、古地形起伏大和構(gòu)造活動強烈的特點而發(fā)育多種成因的砂礫巖扇體[2022],這些扇體臨近烴源巖區(qū)并與其呈指狀接觸,可形成多種類型的油氣藏[23]。近年來,在中國東部斷陷盆地中,近岸水下扇砂礫巖油氣藏勘探取得了重大突破,渤海灣盆地車鎮(zhèn)凹陷北部陡坡帶近岸水下扇砂礫巖油氣藏成功勘探便是典型實例。車鎮(zhèn)凹陷北部陡坡帶位于埕南斷層的下降盤,從東營組至沙河街組發(fā)育了大量的近岸水下扇扇體,這些扇體規(guī)模大,沉積物粒度較粗,油源條件好,勘探潛力大[24]。據(jù)第3次石油資源評價,車鎮(zhèn)凹陷北部陡坡帶砂礫巖體油藏擁有剩余資源量約2×108 t,是勝利油區(qū)勘探的重要領(lǐng)域之一[25]。近年來,完鉆的車66、車660井在車鎮(zhèn)凹陷陡坡帶近岸水下扇扇體中(對應(yīng)次生孔隙發(fā)育帶或“儲層甜點”)獲得日產(chǎn)百噸以上的高產(chǎn)油氣流,標志著近岸水下扇砂礫巖儲層的巨大勘探潛力。但由于陡坡帶近岸水下扇構(gòu)造背景特殊,近物源,沉積速率快,沉積分異差,內(nèi)部結(jié)構(gòu)及沉積規(guī)律復(fù)雜,加之對低孔低滲儲層成巖序列和儲層質(zhì)量認識程度較低,制約了油氣勘探開發(fā)工作。
前人從不同角度對車鎮(zhèn)凹陷陡坡帶沙河街組近岸水下扇砂礫巖儲層的成巖作用開展了研究。綜合研究認為,研究區(qū)成巖作用類型多樣,常見壓實、溶解、膠結(jié)、交代作用,孔喉結(jié)構(gòu)總體較差,儲層物性隨著埋深的增加而變差,但酸性水對長石顆粒及碳酸鹽膠結(jié)物的溶蝕改善了儲層質(zhì)量[2631]。
車鎮(zhèn)凹陷是渤海灣盆地濟陽坳陷的一個北斷南超的次級凹陷,面積2 390 km2。其自南向北又可分為南部緩斜坡帶、斷階帶、中央洼陷帶和北部陡坡帶等4個次級構(gòu)造單元。車鎮(zhèn)凹陷充填沉積了新生界,其中古近系沙河街組自下而上劃分為沙四段、沙三段、沙二段和沙一段。沙四段主要沉積紅色泥質(zhì)巖、藍灰色泥質(zhì)巖和碳酸鹽巖、油頁巖。沙三段至沙二段是湖盆從最大沉陷逐漸回返上升、直至河流與濱淺湖廣布的沉積時期。沙三段主要沉積深湖油頁巖和泥巖夾重力流以及三角洲砂巖。沙二段主要沉積三角洲砂巖、濱淺湖云質(zhì)巖。沙一段發(fā)育較深湖的油頁巖和泥云巖以及濱淺湖灘壩、生物灘成因的鈣質(zhì)砂巖和生物碎屑碳酸鹽巖。
車鎮(zhèn)凹陷北部陡坡帶沙河街組發(fā)育一系列近岸水下扇成因的低孔低滲砂礫巖儲層, 目的層埋深為2 000~3 800 m,沙河街組內(nèi)部具有豐富的油氣或見有不同級別的含油顯示。由于巖性變化大、成分和結(jié)構(gòu)成熟度較低,儲層成巖作用(流巖作用)和油水關(guān)系復(fù)雜,雖經(jīng)多年研究,但成巖作用及其序列對儲層質(zhì)量影響機理及預(yù)測等關(guān)鍵問題還需探討。因此,筆者以渤海灣盆地車鎮(zhèn)凹陷沙河街組近岸水下扇低孔低滲儲層為研究對象,通過系列巖芯和儲層分析化驗資料綜合研究,分析低孔低滲儲層中次生孔隙(“甜點”)的形成條件及控制因素,為低孔低滲油氣藏勘探提供儲層地質(zhì)學(xué)依據(jù)。
1巖石學(xué)特征
渤海灣盆地車鎮(zhèn)凹陷北部陡坡帶車西地區(qū)車66井區(qū)沙三段主要發(fā)育成分和結(jié)構(gòu)的成熟度均較低近岸水下扇(圖1)。儲層巖性主要為巖屑質(zhì)長石砂巖,少量巖屑砂巖(圖2),砂巖粒度變化較大,有粗粉砂巖、細砂巖、中砂巖、含礫不等粒砂巖等。在砂巖顆粒中,石英平均體積分數(shù)為44%,長石平均為32%,巖屑平均為24%,分選中等偏好,磨圓次棱角狀,顆粒支撐。
2儲層物性特征
車鎮(zhèn)凹陷北部陡坡帶車66井區(qū)沙三段65個樣品點的物性數(shù)據(jù)表明(圖3),近岸水下扇砂體為典型的低孔特低滲儲層。儲層孔隙度最大為275%,最小為49%,平均為139%,其中孔隙度為10%~15%的樣品占4688%,孔隙度為5%~10%的占2031%,孔隙度為15%~20%的占1719%,孔隙度小于5%的占1.56%;滲透率最大為511218×10-3μm2,最小為0251×10-3μm2,平均為5765×10-3 μm2,主要集中在(1~10)×10-3 μm2和(10~100)×10-3 μm2,分別占全部樣品的42%和30%。

3成巖作用類型及其特征
3.1壓實作用較強
鏡下觀察發(fā)現(xiàn),車鎮(zhèn)凹陷北部陡坡帶近岸水下扇沙三段儲層巖石顆粒之間的接觸關(guān)系主要為點、線點、點線接觸,偶見云母變形。當埋深淺于2 500 m時,以點、線點接觸為主;當埋深大于2 500 m時,主要表現(xiàn)為點線接觸,說明壓實作用較強。隨著埋藏深度的增加,可出現(xiàn)線、線凹凸接觸,如大675井、大677井2 800~3 000 m井段。
3.2膠結(jié)物類型多
車鎮(zhèn)凹陷車西地區(qū)車66井區(qū)近岸水下扇沙三段存在4種膠結(jié)作用,包括石英次生加大膠結(jié)、碳酸鹽膠結(jié)、黏土礦物膠結(jié)以及重晶石膠結(jié)作用,其中以碳酸鹽膠結(jié)為主。
3.2.1石英次生加大膠結(jié)
石英次生加大膠結(jié)在淺層發(fā)育較少,深層出現(xiàn)較多,如在大51井3 800 m左右,加大邊明顯,寬度為0.1~0.2 mm。
3.2.2碳酸鹽膠結(jié)
圖中數(shù)值為體積分數(shù)
圖2車66井區(qū)沙三段巖石學(xué)特征
Fig.2Lithology of the Third Member of
Shahejie Formation in Well Che66 Area
沙三段膠結(jié)物成分主要有方解石、白云石、鐵方解石、鐵白云石、菱鐵礦等。方解石晶形較好,充填于顆粒之間,或充填在裂縫中;白云石晶體較方解石小得多,分布于顆粒之間;鐵方解石以方解石的加大邊形式存在,或充填在顆粒之間;鐵白云石自形程度較差,晶體較細,充填孔隙(圖4)。隨著埋深增加,方解石膠結(jié)物含量有減小趨勢。埋深處于2 100~2 800 m時,白云石膠結(jié)物平均含量(質(zhì)量分數(shù),下同)為6.8%;埋深小于2 500 m時,其含量小于5%;埋深處于2 500~3 200 m時,白云石的膠結(jié)作

Fig.3Histogram of Physical Properties of the Third
Member of Shahejie Formation in Well Che66 Area
用較強,其最大含量可達28%,說明深層主要為白云石膠結(jié)。

Fig.4Photomicrographs of Carbonate Cements of the Third Member of Shahejie Formation in Well Che66 Area
3.2.3黏土礦物膠結(jié)
發(fā)育的黏土礦物主要有高嶺石、伊利石、綠泥石和伊/蒙混層等。隨著埋藏深度的增加,黏土礦物含量隨之改變。在2 800~3 200 m井段內(nèi),高嶺石含量較高,相對含量最高超過80%。伊利石、綠泥石、伊/蒙混層含量較低,含量在10%左右。

Fig.5Sandstone Dissolution of the Third Member of Shahejie Formation in Well Che66 Area
3.3長石溶蝕作用
鑄體薄片分析表明,沙三段近岸水下扇砂體的溶蝕對象主要為長石,其次為碳酸鹽膠結(jié)物,在2 000~2 400 m和2 600~3 100 m井段內(nèi)溶蝕作用較發(fā)育。如大801井2 310~2 330 m井段,長石溶蝕現(xiàn)象明顯,局部也有少量碳酸鹽膠結(jié)物,生物碎屑被溶蝕,形成孔隙;大677井2 870~2 920 m井段也出現(xiàn)長石以及碳酸鹽膠結(jié)物溶蝕的現(xiàn)象;大671井2 950~3 100 m井段,除發(fā)育長石溶蝕外,還可見巖屑被溶,形成粒內(nèi)溶孔(圖5)。
3.4交代作用
車66井區(qū)沙三段主要發(fā)育長石的高嶺土化、絹云母化和碳酸鹽的交代作用。前者普遍發(fā)育;后者主要表現(xiàn)為方解石、鐵方解石對長石、巖屑的交代作用以及白云石對方解石的交代作用。
4成巖階段與成巖序列
根據(jù)鏡質(zhì)體反射率(Ro)和黏土礦物混層比隨埋深的變化,車鎮(zhèn)凹陷北部陡坡帶車66井區(qū)埋深大于1 500 m的碎屑巖儲層經(jīng)歷了早成巖B期、中成巖A期和中成巖B期等成巖階段(圖6)。
當砂巖埋深為1 500~2 400 m時,巖石進入早成巖B期,Ro值為035%~050%。該階段主要發(fā)生碳酸鹽膠結(jié)、高嶺石膠結(jié)以及碳酸鹽膠結(jié)物的溶蝕作用。長石顆粒以及碳酸鹽膠結(jié)物的溶蝕作用出現(xiàn)以原生孔隙為主的原生次生混合型孔隙。隨著長石溶蝕作用弱→強→弱的變化趨勢,高嶺石的膠結(jié)作用也呈現(xiàn)對應(yīng)變化趨勢;碳酸鹽膠結(jié)作用主要以方解石膠結(jié)作用為主,方解石膠結(jié)物含量可達到25%左右,白云石為5%左右;隨著方解石膠結(jié)作用減弱,白云石膠結(jié)作用逐漸增強;石英次生加大、伊利石膠結(jié)作用都比較弱(圖6)。
圖中寬窄的差異是指成巖作用相對強度的不同
圖6車66井區(qū)儲層成巖演化模式
Fig.6Sandstone Diagenetic Evolution of the Third Member of Shahejie Formation in Well Che66 Area
當砂巖埋深為2 400~3 100 m時,巖石處于中成巖A期。Ro值為050%~130%,黏土礦物混層比迅速降低,該階段主要發(fā)生長石溶蝕、高嶺土膠結(jié)、碳酸鹽膠結(jié)以及石英次生加大作用。碳酸鹽膠結(jié)作用以白云石、鐵白云石膠結(jié)作用為主,含量可達到15%,方解石、鐵方解石膠結(jié)作用相對弱,含量為10%左右;高嶺石膠結(jié)作用逐漸增強,黏土礦物相對含量可達到80%;伊利石的膠結(jié)作用呈現(xiàn)出先逐漸增強、后逐漸減弱的變化趨勢;石英次生加大有增強的趨勢。長石顆粒和碳酸鹽膠結(jié)物溶蝕較為明顯,因此形成了大量次生孔隙(圖6)。
儲層埋深大于3 100 m時,砂巖進入中成巖B期。Ro值為130%~200%,該階段主要發(fā)生黏土膠結(jié)、碳酸鹽膠結(jié)以及石英次生加大作用,孔隙仍以次生孔隙為主。溶蝕作用、晚期鐵方解石和鐵白云石膠結(jié)作用、高嶺石膠結(jié)作用相對減弱,含量約5%;石英次生加大、伊利石膠結(jié)作用相對增強,伊利石膠結(jié)物的相對含量可達到40%左右(圖6)。
5儲層孔隙類型與次生孔隙發(fā)育特征
5.1儲層孔隙類型
鑄體薄片分析表明,車鎮(zhèn)凹陷車西地區(qū)車66井區(qū)沙三段砂巖儲層中存在2種類型孔隙,即原生孔隙和次生孔隙。原生孔隙可細分為壓實剩余的原生粒間孔隙、膠結(jié)剩余粒間孔隙和雜基中的微孔隙。次生孔隙以長石、巖屑顆粒溶蝕形成的粒內(nèi)溶孔和膠結(jié)物溶蝕形成的粒間溶孔為主,鑄???、超大孔和構(gòu)造作用形成的裂縫較少(圖7)。
儲層孔隙經(jīng)歷了由原生到次生的演化過程。當沙三段砂巖埋深淺于2 400 m時,儲層處于早成巖B期,以原生孔隙為主,發(fā)育少量次生孔隙,屬于原生次生孔隙混合發(fā)育帶;當沙三段砂巖埋深大于2 400 m時,儲層已進入中成巖期,次生孔隙發(fā)育,保留少量殘余的原生孔隙(圖6、7)。
5.2次生孔隙發(fā)育深度
圖7表明車鎮(zhèn)凹陷車66井區(qū)儲層次生孔隙發(fā)育在2 300~3 100 m井段。在對應(yīng)的次生孔隙發(fā)育帶(儲層“甜點”),車鎮(zhèn)凹陷陡坡帶車66、車660井在近岸水下扇扇體中獲得日產(chǎn)百噸以上的高產(chǎn)油氣流也證明了該觀點。在2 300 m井段次生孔隙發(fā)育帶內(nèi),平均孔隙度約18%,最大孔隙度可達29%,平均滲透率為93×10-3 μm2,最大滲透率可達690×10-3 μm2;在3 100 m井段次生孔隙發(fā)育帶內(nèi),平均孔隙度為15%,最大孔隙度約25%,平均滲透率為19×10-3 μm2,最大滲透率只有200×10-3 μm2左右。

Fig.7Relationships of Porosity and Carbonate Cement to Depth of the Third Member of
Shahejie Formation in Well Che66 Area
5.3次生孔隙成因
鏡下觀察表明:次生孔隙的形成以長石溶蝕為主,碳酸鹽膠結(jié)物溶蝕次之;隨著埋藏深度的增加,碳酸鹽膠結(jié)物(方解石)溶蝕的程度逐漸增強。依據(jù)碳酸鹽膠結(jié)物在縱向上的分布可以發(fā)現(xiàn),當埋深大于3 100 m時,碳酸鹽膠結(jié)物含量具有較為明顯的降低趨勢,碳酸鹽膠結(jié)物含量約10%,說明在該深度存在碳酸鹽溶蝕(圖7)。高嶺石縱向分布特征也反映出其與長石溶蝕深度的關(guān)系,在2 300 m井段次生孔隙發(fā)育帶附近,高嶺石相對含量可達到50%,在3 100 m井段附近,高嶺石含量異常高,相對含量可達60%~90%,而超過3 300 m深度的井段,高嶺石含量很快下降,平均含量只有10%左右。
6結(jié)語
(1)渤海灣盆地車鎮(zhèn)凹陷北部陡坡帶沙河街組沙三段近岸水下扇砂體儲層質(zhì)量明顯受沉積條件和成巖作用影響。近岸水下扇砂體主要由長石質(zhì)巖屑砂巖組成。在埋藏成巖演化過程中,儲層經(jīng)歷了壓實、膠結(jié)、溶解和交代等成巖過程,多種成巖作用明顯影響了儲層質(zhì)量,總體形成了低孔低滲儲層。
(2)車鎮(zhèn)凹陷北部陡坡帶沙三段近岸水下扇砂體儲層埋深2 000~3 800 m,儲層處于中成巖階段。在成巖演化過程中,溶蝕作用對于改善儲層質(zhì)量起到了重要作用,也就是說,儲層質(zhì)量的改善明顯與溶蝕作用及其形成的次生孔隙發(fā)育深度有關(guān)。車鎮(zhèn)凹陷沙河街組沙三段有利儲層主要發(fā)育在2 300~3 100 m井段,形成的粒間和粒內(nèi)孔隙不僅增加了儲層孔隙度,而且提高了儲層滲透率,改善了儲層質(zhì)量,形成了儲層“甜點”(孔隙度可達25%,滲透率達50×10-3 μm2)。顯然,近岸水下扇有利儲層主要發(fā)育在有機酸溶蝕長石形成的次生孔隙發(fā)育深度段(2 300、3 100 m井段左右)。
(3)發(fā)現(xiàn)溶蝕作用及其形成的次生孔隙發(fā)育深度帶是一項綜合研究工作,應(yīng)該在沉積砂體成因和分布規(guī)律研究的基礎(chǔ)上,開展流巖相互作用和巖石物理相研究,采用定量巖石物理相研究方法,科學(xué)預(yù)測有利儲層空間分布。
