塔里木盆地塔北隆起YKD区块高精度三维地震采集实践
|
Abstract:
为了寻找有利接替区块，实现快速增储上产，围绕断裂及其控制的储层发育区在塔里木盆地塔北隆起YKD区块部署了三维地震采集。针对落实断裂组合、搞清缝洞储层的技术要求，结合工区的自身特点，从获取高信噪比、高分辨率地震资料的目标出发，YKD区块的高精度采集实践通过采用精细观测系统设计、优化激发接收条件以及加强干扰调查分析与控制等措施，获得了高品质的地震资料，为圈闭、井位研究和上产增储奠定了基础。
In order to find favorable replacement blocks and realize rapid reserve increase and production increase, 3D seismic acquisition was deployed in the YBD block of Tabei uplift in Tarim Basin around the fault and its controlled reservoir development area. In response to the technical requirements for implementing fault combinations and clarifying fracture and cave reservoirs, combined with the characteristics of the work area, and with the goal of obtaining high signal-to-noise ratio and high-resolution seismic data, the high-precision acquisition practice of YKD block has obtained high-quality seismic data through measures such as using precise observation system design, optimizing excitation and reception conditions, and strengthening interference investigation, analysis, and control. This has laid the foundation for trap, well location research, and production and storage increase.
