摘要:
苏北盆地A油田的中低孔渗储层,由于受不同成岩作用的影响,孔隙结构复杂,且储层段存在不同流体时的电性关系复杂,基于电法测井的解释图版难于识别储层含油性,测井储层参数的计算精度也偏低。在现有研究成果的基础上,引入综合物性指数C分类选取毛管压力曲线的进汞压力初始点,分类构造相应每一个进汞饱和度下的进汞压力与孔隙度和渗透率之间的对应函数关系,再逐点构造新的毛管压力曲线。通过与实测毛管压力曲线对比可知,该方法所构造的毛管压力曲线可较好地适用于中低孔渗储层。采用该方法计算的含水饱和度与核磁共振计算的束缚水饱和度综合,建立了储层流体的识别图版,在苏北盆地A油田的中低孔渗砂泥岩储层评价中取得了较好效果。
Abstract:
Because of the impact of different diagenesis,the medium to low porosity and permeability reservoirs of A oilfield in Subei basin have complex pore structures and electrical properties of reservoir sections under the condition of different fluids.It is difficult to identify the oil bearing property of reservoirs by the interpretation chart based on electrical logging.And the accuracy of reservoir logging parameters is also low.On the basis of existing researches,a comprehensive physical index C was introduced to select initial points of mercury injection pressures of capillary pressure curves,and construct corresponding functional relationship between the mercury injection pressures corresponding to mercury injection saturations,and porosity and permeability.And then the new capillary pressure curves were established.In comparison with the measured capillary pressure curves,the method was better suited for low porosity and permeability reservoirs.A reservoir fluid identification plate was set up by combining water saturation,calculated by the method,with irreducible water saturation,calculated by NMR.The good effect was achieved in the reservoir evaluation of A oilfield in Subei basin.
