| 摘 要： | 刘桥矿区布设13个钻孔,其中11-6和3-2钻孔发现6煤层有岩浆侵入,在常规地震剖面上难以确定其侵入范围,为此采用地震井约束波阻抗反演技术,即利用钻孔测井数据高纵向分辨率的特点,对井旁地震资料进行井约束反演,在此基础上对井间地震资料进行反演,推断岩浆岩在空间上的变化情况。井下实际揭露的岩性资料表明,波阻抗反演预测的刘桥矿区II62采区岩浆岩分布范围,与实际揭露资料非常一致,其侵入范围主要集中在工作区的西南部。

| Abstract: | There are 13 boreholes laid out in the Liuqiao mine area,in which,6 coal seams have found magmatic intrusions in Nos.11-6 and 3-2 boreholes,but it is very hard to determine intrusive extent.Thus,seismic well constrained wave impedance inversion technique is used,to use logging data high longitudinal resolution characteristics carry out well side seismic data well constrained inversion.On this basis,inversion has carried out for cross-borehole seismic data to deduce spatial variation of magmatic rocks.Lithol... |
