中国石油网消息：8月19日，从东方物探公司获悉，在塔里木盆地阳霞三维工区，该公司自研的GeoEast-FASTomo软件成功突破18000米超大偏移距近地表建模难关，刷新了国产物探软件在该领域的纪录。

China Oil News: On August 19th, it was learned from Dongfang Geophysical Company that in the Yangxia 3D work area of the Tarim Basin, the GeoEast-FASTomo software independently developed by the company successfully overcame the challenge of modeling near the surface with extremely large offset distances of 18,000 meters. This has broken the record of domestic geophysical software in this field.

超大偏移距一般指炮检距≥8000 米的超长观测数据，是复杂地区油气突破的基础前置技术。今年4月，东方物探研究院与物探技术研究中心充分发挥公司一体化技术优势，持续强化软件研发技术合作，共同推动FASTomo技术攻关与应用。

The ultra-large offset distance generally refers to the extremely long observation data with the survey distance of the seismic equipment being ≥ 8000 meters. It is the fundamental preparatory technology for oil and gas breakthrough in complex areas. In April this year, the Eastern Geophysical Research Institute and the Geophysical Technology Research Center fully leveraged the company's integrated technical advantages, continuously strengthened software research and development technical cooperation, and jointly promoted the research and application of the FASTomo technology.

在阳霞三维工区，项目总炮数达12万炮，单炮接收道达6万道。针对现有集群算力适配不足等问题，联合攻关组技术人员下沉生产机房，联合开展问题定位、参数调整和方案验证。双方结合本地集群特点，实施多节点内存共享、二叉队列并行优化，破解了算力与运行稳定性瓶颈，实现了20小时连续平稳运算，顺利建成合格速度模型，数据体量超过常规工区的4倍。

In Yangxia 3D work area, the total number of project shells reached 120,000, and the number of receiving channels per shell reached 60,000. In response to the insufficient adaptability of the existing cluster computing power and other issues, the technical personnel of the joint research team went down to the production computer room and jointly carried out problem location, parameter adjustment and scheme verification. Both parties combined the local cluster characteristics and implemented multi-node memory sharing and binary queue parallel optimization, breaking through the bottleneck of computing power and operational stability, achieving 20 hours of continuous and stable operation, successfully building a qualified speed model, and the data volume exceeded four times that of a regular work area.

截至目前，该技术已在土北401、丽探1井、阳霞三维等重点工区落地应用，稳定性、适配性和生产支撑能力显著提升，处理效率达到同类商业软件10倍以上，为复杂区、超深层油气勘探提供了有力技术支撑。

Up to now, this technology has been applied in key work areas such as Tuobei 401, Li Teng 1 well, Yangxia 3D, etc. Its stability, adaptability and production support capabilities have been significantly enhanced. The processing efficiency has reached more than 10 times that of similar commercial software, providing strong technical support for complex areas and ultra-deep oil and gas exploration.
