一、多检波器与多炮井面积组合联合试验主要采用了如下因素:(1)检波器面积组合图形一般采用矩形,沿测线每排7—13个检波器,最多用五排共65个,组合点距7.5米或10米,排距20米(见图1.1-1)。(2)炮井组合也是矩形,井距大部分为20—30米,排距20米,沿测线每排3—5口井,最多用五排,共25口井。井深10—15米,有些地段用20—25米,每口井炸药 First, the combination of multi-detector and multi-gun well area joint test mainly uses the following factors: (1) detector area combination of graphics generally rectangular, along the line 7-13 detectors per row, up to five rows of a total of 65 , A combination of 7.5 meters or 10 meters pitch, row spacing of 20 meters (see Figure 1.1-1). (2) The well combination is also a rectangle with a well spacing of mostly 20-30 meters and a row spacing of 20 meters. There are 3-5 wells in each row along the survey line, with a maximum of five rows of 25 wells. Well 10-15 meters deep, some sections with 20-25 meters, each well explosives
