摘要
在对柴达木盆地红柳泉地区下干柴沟组下段砂层组细分层对比中,共划分出4个砂层组。运用小层对比技术,将I砂层组划分为12个小层,并建立了井间对比模式。通过将该砂层组骨干剖面展开并对其进行了全面的小层对比,科学地指导了研究区细分层的精细对比和对砂体展布的正确认识。
Sand is divided into four members in the lower member of Lower Ganchaigou Formation in the Hongliuquan area of the Qaidam basin. We carry out the control in grades from parasequence to sublayer vertically. On the basis of sublayer correlation, Sand Membe I is divided into twelve sublayers, and the mode of interwell correlation is also established. By spreading backbone profile, the sand members in the lower member of Lower Ganchaigou Formation are correlated comprehensively. It provides scientific guidance for the research of fine correlation of layer subdivision and distribution of sand body.
