东濮复杂地表区高精度采集质量控制方法与实践

Methods and Practice of High-precision Acquisition Quality Control of Complex Surface Areas in Dongpu Sag

针对东濮凹陷中央隆起带复杂地表区(表层结构复杂多变、地表障碍密布)的特点,细化设计指标,对环节目标管理的过程进行探讨,对单线设计、总结的内容、点位布设的方法、要求和工序环节管理目标、办法进行阐述。用CDP偏移距分布目标控制过障设计,实现最小面元覆盖次数均匀,点位正确性的细化要求,精确的表层调查方案,小药量补偿方案等,这些指标、措施、办法的落实确保了复杂地表区高精度采集资料质量。

In view of the features(complicated and changeable superficial structures,closely set obstructions on earth surface) of central uplift belts in Dong sag,the design target is refined,the process of links target administration is discussed,the single line design,conclusions,the means and requirements of point layout and the administration target of procedure links are elaborated in this paper.CDP offset distribution target may be used to control the evading obstructions design,so as to make the minimum binning fold more uniform,meet the delicate requirements of point exactitude,obtain accurate surface investigation scheme and little explosive compensation plan.All these indexes,treatments and measures may ensure the quality of high-precision acquisition in complex surface area.
