为了满足海底ZD、3D多分量（4C）勘探采集地震记录的需求，SchlumbefgerGeco－Prakla公司最近增派了一艘4C地震勘探船到北海。这家公司证实全球4C勘探使石油公司迅速明白了4C资料的价值，尤其对含气成像及用常规海上拖缆数据无法探测到的低阻抗差地区成像寻找油气卓有成效。首?
To meet the seabed ZD, 3D multi-component (4C) exploration seismic acquisition needs, SchlumbegerGeco-Prakla recently added a 4C seismic vessel to the North Sea. The company confirms that global 4C exploration has enabled oil companies to quickly understand the value of 4C data and is particularly effective in gas and oil imaging looking for imaging in areas of low impedance that are not detectable with conventional ocean streamers. first?
