在任何勘探地区,要避免钻井计划中浪费时间及费用过高的差错出现,精确的深度转换是很关键的。不论是在陆上勘探还是海上勘探,勘探家精细的钻井预测对钻井工程师制定经济而安全的钻井计划是很重要的。此外,深度转换用于计算确定地热史所需要的埋藏深度,为精确的地质控制提供深度模型,并为流体流动模拟提供保证。本文研究工作站环境中解释员推导和证明地震解释深度转换的必要步骤。地球物理解释从识别区域地震标准层、盆地不整合面和层序边界开始,以得出盆地的总体构造骨架。基本骨架一旦建立,就开始识别由地震表示的地质分层工作。要使地层顶部和地震
In any exploration area, to avoid the waste of time and costly errors in the drilling program, accurate depth conversion is critical. Whether onshore or offshore exploration, careful drill predictions by surveyors are important to the drilling engineer in developing an economical and safe drilling program. In addition, depth conversion is used to calculate the depth of burial needed to determine geothermal history, provide a deep model for accurate geological control, and provide a guarantee for fluid flow modeling. This paper studies the necessary steps for interpreters in workstation environments to derive and prove the depth conversion of seismic interpretation. Geophysical interpretation begins with the identification of regional seismic standards, basin unconformities, and sequence boundaries to arrive at the overall structural skeleton of the basin. Once established, the basic skeleton begins to identify the geologic stratification represented by the earthquake. To make top of strata and earthquakes
