MDT测井资料在南海东部油藏的应用
|
摘要
在非均质性强的砂岩地层中,常规测井资料无法解释的一些疑难问题(如常规测井资料无法确定储层纵横向上的连通性、气水界面判断不准、疑难层的流体性质判断不清等),可以通过电缆试地层测试资料的应用得以解决,并起到了较好的地质效果。MDT(模块式地层测试)测井新技术能够及时、快捷、准确地获取储层流体、压力资料,把许多需要在试油及勘探评价阶段才能解决的问题通过MDT测试就得以了解、认识,从而有效地减少试油工程的投入,也为油藏的储量计算提供了较准确的参数。
In highly heterogeneous sandstone formations, some difficult problems can't be interpreted by conventional logging data. For example, the inability of conventional logging data will determine the vertical and horizontal connectivity of reservoirs, including the inaccuracy of gas-water interface judgment, the unclear judgment of fluid properties of difficult formations, etc. These problems can be solved by MDT data.MDT(Modular Formation Testing) logging technology can acquire reservoir fluid and pressure data promptly, quickly and accurately. Many problems to be solved in the stage of oil testing and some exploration evaluation can be understood and acquainted through MDT testing. Thus, it will effectively reduce the investment of oil testing engineering to provide more accurate parameters for reservoir reserves calculation.
