“三低”油藏硼中子寿命测井水淹层解释方法

Water-out Reservoir Interpretation with BNLL in Low Porosity , Low Permeability and Low Salinity Reservoirs

硼中子寿命测井(BNLL)是吐哈油田目前套管井中“三低”(低孔、低渗、低矿化度)油藏水淹层解释一种非常重要的方法,它能直观显示油层的水淹程度及流体性质。通过定量解释方法研究与实例,显示出BNLL测井技术在寻找剩余油方面的独特作用。

BNLL is one of the important methods of water-out reservoir interpretation of low porosity, low permeability and low salinity reservoirs in casing wells of Tuha Oilfield, by which the water-out degree and fluid properties are displayed visually, the special action of BNLL logging technique in finding out residual oil is demonstrated through quantitative interpretation and examples.
