由于缺乏较为完善的多波解释软件,使得多波解释工作难以顺利开展。因此研制具有自主知识产权的多波解释软件为三分量地震资料解释提供实用工具,为多波技术提供研究平台,填补国内多波软件空白十分必要。在参照引进的商业软件系统和自身探索多波解释方法、技术的基础上,研究了多波合成记录、层位标定、层位联合对比与匹配,基于PP波和PS波反射系数近似公式的AVO线性联合反演等关键技术,以及满足山地地震资料逆断层解释需要的交互方法。以此为基础,开发了一套二维三分量解释软件,能完成二维三分量地震资料解释和多波联合反演。应用该软件完成了四川盆广安地区二维三分量地震资料解释,并进行了目标气层的多波联合反演,解释了含气范围,取得明显的效果。
Due to the lack of a more complete multi-wave interpretation software, it is difficult to carry out multiwave interpretation smoothly. Therefore, the development of multi-wave interpretation software with independent intellectual property rights provides a practical tool for three-component seismic data interpretation, providing a research platform for multi-wave technology and filling the gap of multi-wave software in China. Based on the introduction of the commercial software system and its own exploration of multi-wave interpretation methods and techniques, multi-wave synthesis recording, horizon calibration, layer combination and matching are studied. Based on the approximate formulas of PP wave and PS wave reflection coefficient, AVO Linear joint inversion and other key technologies, as well as interactive methods to meet the needs of reverse seismic interpretation of mountain seismic data. Based on this, a set of two-dimensional three-component interpretation software was developed, which can accomplish two-dimensional three-component seismic data interpretation and multi-wave joint inversion. The software was used to complete the interpretation of 2D three - component seismic data in Guang’an area of Sichuan Province. Multi - wave joint inversion of target gas layer was carried out, the gas content was explained, and the obvious effect was achieved.
