温艳军,果二杨:三维地震在段六拔油田勘探和开发中的应用,《石油地球物理勘探》,23(2)1987:206～218 段六拔地区,在二维地震成果基础上钻了6口探井,除官66井获工业油气流外,其余5口井都未获得满意的结果。其原因是构造形态不清,油藏圈闭类型不清,岩性变化规律不清。后来在此区40.39km~2面积上作了三维地震。三维资料的信噪比有了明显的提高,断点清晰,小断层也准确可靠,目的层反射突出,连续性有了较大的改善,并提供了岩性分析资料。在对三维资料全面分析的基础上,又钻了4口井,其中有两口井见到工业油流。并对三维工区原来未见油的某些井进行重新试油,结果获得了新的含油层。三维地震不但加快了段六拔地区的勘探和开发,而且收到了较高的经济效益。
Wen Yanjun and Guo Eryang: Application of Three-Dimensional Earthquake in Exploration and Development of Duanlabuguang Oilfield, Petroleum Geophysical Prospecting, 23 (2) 1987: 206 ~ 218 Liulupu Area was drilled on the basis of two-dimensional seismic results Six exploration wells, in addition to the official wells 66 were industrial oil and gas flow, the remaining five wells did not get satisfactory results. The reason is that the structural shape is unclear, the types of reservoir traps are unclear, and the laws of lithology are not clear. Later in this area 40.39km ~ 2 area made a three-dimensional earthquake. The signal-to-noise ratio of three-dimensional data has been obviously improved, the breakpoint is clear, the small fault is also accurate and reliable, the reflection of the target layer is outstanding, the continuity is greatly improved, and the lithology analysis data are provided. On the basis of a comprehensive analysis of three-dimensional data, four more wells were drilled, of which two wells saw industrial oil flow. And re-tested some of the wells in the 3D work area where no oil was originally found. As a result, a new oil-bearing formation was obtained. Three-dimensional earthquakes not only accelerated exploration and development of the Duanliudu area, but also received higher economic benefits.
