关于油气勘探科技创新的思考

Consideration on scientific and technological innovation of the oil and gas exploration

论述了油气勘探新技术与创新成果的辩证关系。认为近年来油气储量的增长主要得益于勘探技术的进步,但其形成的生产力还与以往大量的基础性工作有关。就目前的创新成果而言,对技术含量的过分追求导致基础性研究滞后,从而使成果的含金量渐显不足。文章引用一批现代典型范例,解译了科技创新内涵,旨在引起大家对油气勘探创新研究的思考,并由此创造扎实浓厚的科技创新氛围。

The high frequency information in VSP data can be used to enhance the resolution of 3D surface seismic data. A new method -wavelet replacement is presented in this study. The wavelet of surface seismic data is permuted by wavelet from VSP of zero offset. It is realized by wavelet replacement deconvolution in data processing. The efficiency of this method is proved by theoretical wavelet computation and slanting layers modeling. The correlation of wavelet can be derived from seismic records in real data processing. Result of processing of real seismic section shows the advantage of method that while the main frequency and high-cut frequency of reflection increases effectively and the low frequency ingredient is protected properly. The width of frequency band of surface seismic data is extended and resolution is enhanced.
