灵活二维观测系统是一种新的二维勘探方法。通过合理布设炮点和检波点位置, 达到线元可分的目的。与常规二维观测系统相比, 该方法具有施工投入少, 过障碍能力强的优点; 通过变线元处理可为资料解释提供多种不同覆盖次数的剖面, 适合于勘探程度低、地表复杂的地区应用。

D flexible layout is a newly developed layout in 2-D seismic exploration. With rational deployment of shots and receivers, the goal of bin division can be achieved. Comparing with conventional 2-D ones, this layout has advantages of lower operation cost and higher ability of crossing obstacles. The method can provide seismic sections of different folds for interpretation through bin division, which is helpful in areas with low degree exploration and complex surface conditions. The application effect was illustrated in the paper.
