依据断层生长指数、断层上下盘岩矿特征、油气性质对比分析等明确了断层的垂向输导性能,通过砂体物性条件、荧光定量评价特征等刻画了砂体横向输导性。结果表明:车排子地区断层垂向输导指数大于1时,具有垂向输导作用;当砂体输导指数大于2时,油气具有横向输导能力;在实际地质条件下,油气只有同时满足断层、砂体有效输导条件才能进行长距离运移;建立了断层、砂体输导数学模型,结合油气分布提出了断层和砂体的有效输导下限。
Based on the fault growth index, the features of upper and lower rocks and rocks, the comparative analysis of oil and gas properties and so on, the vertical conductivity of faults is confirmed. The lateral conductivity of sand body is characterized by physical properties of sand body and quantitative evaluation of fluorescence. The results show that: when the vertical conductivity index of fault in Chepaizi area is greater than 1, it has the vertical conductivity; when the permeability index of sand body is more than 2, the oil and gas have lateral conductivity; under the actual geological conditions, The faults and sand bodies can meet the requirements of long-distance transportation. The mathematical models of fault and sand body transport are established, and the effective lower limit of faults and sand bodies are proposed based on the distribution of oil and gas.
