準噶爾盆地地層符號使用規(guī)范

準噶爾盆地地層名稱及符號使用規(guī)范新疆油田公司2006年7月準噶爾盆地地質分層及代號說明1、巖石地層單元群、組沿用以往方案，相應地質符號以《西北區(qū)域地層表新疆維吾爾自治區(qū)分冊》為標準，但二疊系采用三分原則，石炭系采用二分原則。2、亞組仍沿用本區(qū)以往命名習慣，地質符號自下而上排序，序號為下標。如克拉瑪依組下亞組（T2k1）、克拉瑪依組上亞組（T2k2）；佳木河組下亞組（P1j1）、佳木河組中亞組（P1j2）、佳木河組上亞組（P1j3）。3、地層單元分段自下而上排序，序號為下標。如八道灣組一段（J1b1）、八道灣組二段（J1b2）、八道灣組三段（J1b3）。4、砂組是比段次一級的地層（或沉積）單元，砂層則是比砂組更次一級的地層（或沉積）單元，兩者劃分皆自上而下排序，序號均為上標，砂組序號與砂層序號之間用“-”連接。如三工河組二段一砂組（J1s21）、三工河組二段二砂組（J1s22）；呼圖壁河組一段一砂組一砂層（K1h11-1）、呼圖壁河組一段一砂組二砂層（K1h11-2）。5、尚未細分的地層單元今后若需細分，須嚴格參照上述規(guī)范執(zhí)行。6、除在表格和圖件中為了簡便可使用地層單元代號外，在各類報告和設計中的其他部分（包括表和圖的題名）均應采用地層單元名稱。7、地層單元命名須按地層分區(qū)圖進行，地層代號參照附表1~4。8、本標準自發(fā)布之日起執(zhí)行。新疆油田公司2006年7月31日準噶爾盆地地層分區(qū)準噶爾盆地地層分區(qū)ⅠⅡⅢⅠ：西北緣—腹部地層小區(qū)Ⅱ：準南地層小區(qū)Ⅲ：準東地層小區(qū)附表1準噶爾盆地西北緣地層表及地質符號界系統(tǒng)群組原方案現方案段(亞組)砂層組段(亞組)砂層組新生界新近系上新統(tǒng)獨山子組N2d中新統(tǒng)塔西河組N1t沙灣組N1s古近系漸新—始新統(tǒng)烏倫古河組E2-3w古新統(tǒng)中生界白堊系上統(tǒng)紅礫山組K2d艾里克湖組K2下統(tǒng)吐谷魯群K1tg連木沁組K1勝金口組K1s呼圖壁河組K1h清水河組K1q侏羅系上統(tǒng)齊古組J3q中統(tǒng)頭屯河組J2t水西溝群J1-2sh西山窯組J2x下統(tǒng)三工河組J1sJ1s1S1J1s3J1s2S21或J1s21J1s2J1s21S22或J1s22J1s22J1s3S31或J1s31J1s1J1s11S32或J1s32J1s12S33或J1s33J1s13八道灣組J1bJ1b1B11或J1b11J1b3J1b31B12或J1b12J1b32B13或J1b13J1b33J1b2B2J1b2J1b3B31或J1b31J1b1J1b11B32或J1b32J1b12B33或J1b33J1b13B34或J1b34J1b14三疊系上統(tǒng)白堿灘組T3b中統(tǒng)克拉瑪依組T2k上亞組T2k2S1上亞組T2k2T2k21S2T2k22S3T2k23S4T2k24S5T2k25下亞組T2k1S6下亞組T2k1T2k11S7T2k12S8T2k13下統(tǒng)百口泉組T1bS9古生界二疊系上統(tǒng)上烏爾禾組P3w中統(tǒng)下烏爾禾組P2w夏子街組P2xP2x1P2x3P2x2P2x2P2x3P2x1下統(tǒng)風城組P1P1fP1fP1fP1fP1fP1fP1fP1f佳木河組P1jP1j1P1j3P1j2P1j2P1j3P1j1石炭系附表2準噶爾盆地腹部地層表及地質符號界系統(tǒng)群組原方案現方案段砂層組段砂層組新生界第四系下更新統(tǒng)西域組Q1x新近系上新統(tǒng)獨山子組N2d中新統(tǒng)塔西河組N1t沙灣組N1s古近系漸新—始新統(tǒng)安集海河組E2-3古新統(tǒng)紫泥泉子組E1-2z中生界白堊系上統(tǒng)紅礫山組K2h艾里克湖組K2下統(tǒng)吐谷魯群K1tg連木沁組K1勝金口組K1s呼圖壁河組K1hK1h2h21K1h2K1h21h22K1h22K1h1h11K1h1K1h11h12K1h12清水河組K1qK1q2K1q2K1q1K1q1侏羅系中統(tǒng)頭屯河組J2tJ2t1J2t3J2t2J2t2J2t3J2t1水西溝群J1-2sh西山窯組J2xJ2x1X1J2x4J2x2X2J2x3J2x3X3J2x2J2x4X4J2x1下統(tǒng)三工河組J1sJ1s1S1J1s3J1s2S21或J1s21J1s2J1s21S22或J1s22J1s22J1s3S31或J1s31J1s1J1s11S32或J1s32J1s12S33或J1s33J1s13八道灣組J1bJ1b1B11或J1b11J1b3J1b31B12或J1b12J1b32B13或J1b13J1b33J1b2B2J1b2J1b3B31或J1b31J1b1J1b11B32或J1b32J1b12B33或J1b33J1b13B34或J1b34J1b14三疊系上統(tǒng)小泉溝群T2-3xq白堿灘組T3b中統(tǒng)克拉瑪依組T2k上亞組T2k2上亞組T2k2下亞組T2k1下亞組T2k1下統(tǒng)百口泉組T1b古生界二疊系上統(tǒng)上烏爾組P3w中統(tǒng)下烏爾組P2w夏子街組P2x下統(tǒng)風城組P1佳木河組P1j石炭系附表3準噶爾盆地南緣地層表及地質符號界系統(tǒng)群組原方案現方案段砂層組段砂層組新生界第四系下更新統(tǒng)西域組Q1x新近系上新統(tǒng)獨山子組N2d中新統(tǒng)塔西河組N1t沙灣組N1s古近系漸新—始新統(tǒng)安集海河組E2-3E2-3aE2-3aE2-3aE2-3aE2-3aE2-3a古新統(tǒng)紫泥泉子組E1-2zE1-2z3E1-2z3E1-2z2E1-2z2E1-2z1E1-2z1中生界白堊系上統(tǒng)東溝組K2d下統(tǒng)吐谷魯群K1tg連木沁組K1勝金口組K1s呼圖壁河組K1h清水河組K1q侏羅系上統(tǒng)喀拉扎組J3kJ3k2J3k2J3k1J3k1齊古組J3qJ3q3J3q3J3q2J3q2J3q1J3q1中統(tǒng)頭屯河組J2tJ2t3J2t3J2t2J2t2J2t1J2t1水西溝群J1-2sh西山窯組J2x下統(tǒng)三工河組J1sJ1s3J1s2J1s21J1s22J1s1J1s11J1s12J1s13八道灣組J1bJ1b3J1b2J1b1三疊系上統(tǒng)小泉溝群T2-3xq郝家溝組T3hj黃山街組T3h中統(tǒng)克拉瑪依組T2k下統(tǒng)上倉房溝群T1chb燒房溝組T1s韭菜園組T1j古生界二疊系上統(tǒng)下倉房溝群P3cha梧桐溝組P3w泉子街組P3q中統(tǒng)上芨芨槽群P2jjb紅雁池組P2h蘆草溝組P2井井子溝組P2j烏拉泊組P2w下統(tǒng)下芨芨槽群P1jja塔什庫拉組P1t石人子溝組P1s石炭系上統(tǒng)奧爾吐組C2祁家溝組C2q柳樹溝組C2附表4準噶爾盆地東部地層表及地質符號界系統(tǒng)群組原方案現方案段砂層組段砂層組新生界第四系新近系古近系中生界白堊系上統(tǒng)紅礫山組K2h下統(tǒng)吐谷魯群K1tg連木沁組K1勝金口組K1s呼圖壁河組K1hK1h2h21K1h2K1h21h22K1h22K1h1h11K1h1K1h11h12K1h12清水河組K1q侏羅系上統(tǒng)石樹溝群J2-3sh喀拉扎組J3kJ3k2J3k2J3k1J3k1齊古組J3qJ3q3J3q3J3q2J3q2J3q1J3q1中統(tǒng)頭屯河組J2tJ2t3J2t3J2t2J2t2J2t1J2t1水西溝群J1-2sh西山窯組J2xJ2x1J2x4J2x2J2x3J2x3J2x2J2x4J2x1下統(tǒng)三工河組J1sJ1s1S1J1s3J1s2S21J1s2J1s21S22J1s22J1s3S31J1s1J1s11S32J1s12S33J1s13八道灣組J1bJ1b2B11J1b3J1b31B12J1b32B13J1b33J1b1B2J1b2B31J1b1J1b11B33J1b12B32J1b13三疊系上統(tǒng)小泉溝群T2-3xq郝家溝組T3hj黃山街組T3h中統(tǒng)克拉瑪依組T2k下統(tǒng)上倉房溝群T1chb燒房溝組T1s韭菜園組T1jT1j1T1j2T1j2T1j1古生界二
