摘要:
大庆长垣背斜SZ油田G油层油水同层段具有一定的储量规模且开发程度低,随着油田剩余储量精细挖潜需求及产量压力的日益增加,需针对油水同层段开展测井解释评价研究,在测井精细量化解释基础上进一步补孔挖潜对油田稳产具有重要的意义。针对G油层储层薄、泥质含量高、含钙等特点,在“四性”关系研究基础上,明确测井响应主要影响因素,提出各项校正方法,突出储层流体信息特征。采用并联导电模型和电阻率基线比值法对泥质和钙质进行校正,基于实验室分析资料建立薄层校正方法,结合试油和两相流渗流规律,基于可动水和束缚水饱和度建立油水同层产水率分段预测解释标准。该方法在实际应用中见到良好效果,为油水同层补孔挖潜提供了有力技术支撑。
Abstract:
G reservoir in Daqing placanticline SZ oilfield the same oil-water interval has a certain reserve scale and low development degree. With the increasing demand for fine potential tapping of remaining reserves in oilfield and production pressure, it is necessary to carry out the research on quantitative interpretation standard of well logging for the same oil-water interval. It is of great significance to further supplement perforation and tap potential on the basis of fine quantitative log interpretation for stable production of the oilfield. According to the characteristics of G reservoir, such as high shale content, common calcium content and thin thickness, based on the study of “four properties” relationship, the main influencing factors of logging response are identified, and the correction method is proposed to highlight the reservoir fluid information characteristics. The parallel conductivity model and resistivity baseline ratio method are used to correct the mud and calcium. The thin layer calibration method is established based on laboratory analysis data. Combined with the principle of oil testing and relative permeability curve, based on the saturation of movable water and irreducible water, the quantitative prediction and interpretation standard of water production in the same oil-water layer is established, which has achieved good results in practical application and provided strong technical support for the same oil-water interval perforation adding and tapping potential.
