GeoMountain多波解释软件研发与应用
|
摘要
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。
Multi-wave interpretation is hard to be done smoothly for lack of relatively perfect multi-wave interpretation software.Therefore,to develop multi-wave interpretation software with independent intellectual property right is of great importance in providing a practical tool for three component seismic data analysis as well as a research platform for multi-wave technique and in filling gaps of domestic multi-wave software.Based on the reference of the introduced commercial softwares and our own accumulated techniques on multi-wave interpretation,this paper not only carries out research into such key techniques as multi-wave synthetic seismograph,horizon calibration,horizon joint correlation as well as matching and AVO linear joint inversion based on approximate formula of PP wave and PS wave's reflection coefficient but also gets an interactive method meeting the requirement for the interpretation of reverse fault in mountain areas.On this basis,a set of 2D three component interpretation software was developed which can finish 2D three component seismic data interpretation as well as multi-wave joint inversion.As a result,the 2D three component seismic data in Guang'an region of Sichuan basin has been interpreted,multi-wave joint inversion of the target gas-bearing layer has been done and a gas-bearing range has neen interpreted by use of this software.
