摘要
五维规则化技术是目前室内处理常用的空间采样不均消除手段。但是,对于浅层致密气这类岩性储层,傅里叶变换造成的混波现象导致五维规则化技术不能满足其高保真处理的要求。以川中地区沙溪庙组资料为例,对五维规则化流程进行优化,提出了一种高保真规则化技术。研究结果表明,在针对浅层致密气勘探的资料处理中,高保真规则化技术能在提高信噪比的同时,更好地达到保真的要求,有利于浅层陆相致密气解释工作的开展。
5D regularization technology is commonly used in eliminaton of the unevenness of spatial sampling.However,as a result of the mixing signal phenomenon caused by Fourier transform,5D regularization technology can not meet the requirements of high fidelity processing of lithologic reservoirs such as shallow tight gas.Taking the data of Shaximiao Formation in central Sichuan as an example,the 5D regularized process is optimized and then a high fidelity and regularization technology is proposed.The results show that in the data processing of lithologic prospecting of shallow tight gas,the high fidelity and regularization technology can better meet the high-fidelity requirements while improving the signal-to-noise ratio,and is more conducive to the interpretation of shallow tight gas.
