| 摘 要： | 侏罗系三工河组是准噶尔盆地腹部重要的勘探目的层系,近年来取得了一系列重要的油气发现.利用钻井、测井以及地震资料对腹部地区117口钻井进行分层,在进行砂体厚度、含砂率统计的基础上,编制了三工河组一段、二段(包括一砂组和二砂组)、三段的砂体等厚图,并结合取心井的岩心观察,编制了相应层段的沉积相图.准噶尔盆地腹部,尤其是中石化区块,主要受来自于盆地西北缘及东部卡拉麦里物源的控制,三工河组二段是砂体最发育的时期,主要沉积相类型为三角洲,是主要的含油气层系.

| Abstract: | The Sangonghe formation of Jurassic is a very important exploration target and a series of significant achievements have been achieved. Take advantages of drilling, logging and seismic data, the Sangonghe formation of one hundred and seventeen wells were divided, on the basis of the thickness of sand bodies and sand percentage, isopach map and sedimentary facies map of J1s1, J1s21 , J1s22 and J1s3 were drawn. In the back-land of Junggar Basin, especially in the registered region of Sinopec, Sedimentary facies types and sandstone distribution were mainly affected by the North-Western and Eastern sediment sources. The 2nd sand segment of Sangonghe formation, oil and gas bearing zone, is the most developed part and the sedimentary facies is delta. |
