地震勘探技术在焉耆盆地勘探开发中的应用
|
摘要
地震勘探技术可以分为以二维地震为主的地震勘探初期阶段、以地震地层学为主的地震勘探中期阶段、以三维地震为主的地震勘探高级阶段、以地震储层研究为主的开发地震初级阶段和以四维地震为主的开发地震高级阶段。针对不同阶段的地质条件和不同的地质任务 ,选择合理的地震勘探技术可有效提高勘探开发效益。焉耆盆地的勘探开发体现了以地震勘探为主的思路 ,在勘探开发过程中重视了针对不同勘探开发阶段和不同的地质目标选择合理的地震技术 ,因此 ,在早期勘探开发中取得了很好的经济效益。
Petroleum exploration and production can be roughly divided into five stages. Stage one is the early stage of seismic exploration, in which 2D seismic techniques are the main means of exploration. In stage two, seismic stratigraphy becomes the main means of exploration. Stage three is the advanced stage of seismic exploration, characterized by wide use of 3D seismic. Stage four is the primary phase of production seismics, in which reservoirs enjoys priority in investigation. Stage five is the advanced phase of production seismics, characterized by wide application of time-lapse seismic. Seismic techniques adopted should be in accordance with various geologic settings and missions of different stages to reach desired results of exploration and production. In the exploration and production of Yanqi Basin, proper seismic techniques were used according to different stages and targets. Remarkable economic results therefore have been reached in the early stage of exploration and production.
