李厚义,张志安,宋长伟,李刚.油层水电阻率的研究及应用效果.测井技术,1998,22(4):299~302陆相油藏形成过程中,油层在微孔隙中保留了其成岩时的原生水,即束缚水,水层则在渗流孔隙中含自由水。油层中的束缚水与水层中的自由水可能具有不同的矿化度。对陆相沉积油藏而言,只有用束缚水电阻率求解油层的含水饱和度才是正确的。为此导出了束缚水电阻率模型及含水饱和度方程,说明各油田只要具备基本的地质分析资料都可以求得适合本油田地质特点的饱和度方程,进而求取油和水的相对渗透率、产水率、残余油饱和度方程。给出了该方法在二连某油田的应用效果。
Li Houyi, Zhang Zhi’an, Song Changwei, Li Gang. Study and application effect of reservoir water resistivity. Logging Technology, 1998,22 (4): 299 ~ 302 During the formation of continental facies reservoirs, the reservoirs retain the primary water during its diagenesis, ie, bound water, while the water layer contains free water in the seepage pores . Bound water in the reservoir may have a different degree of salinity than free water in the aquifer. For terrestrial sedimentary reservoirs, it is only right to use the bound water resistivity to solve the reservoir water saturation. For this reason, the bound water resistivity model and the water saturation equation were derived, which indicated that the saturation equations suitable for the geologic characteristics of the oilfield can be obtained by using the basic geological analysis data of each oilfield, then the relative permeability of oil and water could be obtained, Water production rate, residual oil saturation equation. The application effect of this method in Erlian Oilfield is given.
