该文以克拉玛依油田下克拉玛依组为目的层,采用“层次分析”与“模式拟合”的研究思路,对冲积扇储层内部构型进行深入解剖。以现代沉积和野外露头为原型模型,通过对水平井、密井网及小井距的解剖,系统总结了不同相带、不同旋回内部砂砾岩体及隔夹层的展布特征,分析了不同井距条件下单一砂体的控制程度,并建立了研究区的沉积模型。 Based on the Karamay Formation in the Karamay Oilfield, this paper uses the research ideas of “level analysis” and “pattern fitting” to deeply dissect the internal configuration of alluvial fan reservoirs. Based on the modern sedimentary and outdoor outcrops as prototype models, the distribution characteristics of sandstone bodies and intercalations in different facies belts and different cycles are summed up through the dissection of horizontal wells, close well networks and small well spacing. The different well spacing Under the conditions of a single sand body control, and established the deposition model of the study area.
