DELOG的研制及在薄互层油气勘探中的应用

THE DEVELOPMENT OF DELOG AND THE APPLICATION OF HYDROCARBON EXPLORATION IN THIN INTERBEDS

本文提出的方法是大庆石油管理局自行研制的新的人工合成声波测井技术,它的分辨能力不但高于经常规方法处理的地震剖面,也明显地高于经国外的Seislog和Velog处理的剖面。 Delog通过在大庆油田朝94井区等三个地区的应用,可以认为它在薄层砂体预测、划分沉积微相、检测低速异常以及进一步预测孔隙度、渗透率、压力梯度等参数做出了贡献,为合理圈定含油气面积,计算地质储量提供了依据。

The method introduced in this paper is a new synthetic acoustic log technique developed by Daqing Petroleum Administrative Bureau itself. The resolution of the method is not only higher than that of the seismic profile processed by conventional methods, but also obviously higher than those processed by the imported Seislog and the Velog methods. By using the Delog in Wells Chao 94 etc. three areas in Daing oilfied, it shows that it makes a contribution to predicating laminated sand bodyies, de-viding sedimentary mini facies, detecting low-velocity anomaly and further predicating porosity, permeability and pressure gradient factors.lt provides a basis for reasonably identifying hydrocarbon-bearing areas and to calculat OOIP.
