摘要:

为了制定陇东环县油区M井区长8储集层合理的单井生产方案、确保M井区产能最优化,将岩性、物性和含油性等储集层静态地质特征与渗流规律、生产状况等动态特征研究相结合,基于M井区的地质资料、岩心资料、相渗分析资料和测井资料等开展了储集层特征、剩余油分布规律及单井产能预测,预测了M井区合理的单井产量。研究表明:M井区长8储集层具备典型的超低渗透储集层特征,测井响应特征较为显著,储集层呈现对油水的双重润湿性;M井区油藏为构造岩性油藏,油水分布受到岩性控制作用,沿着河道方向,物性好、含油性好、在构造相对高部位含油性好;M井区产量主要来自于M井区中-东南部,目前剩余油在平面上主要分布在M井区北部、中南部局部区域;物性参数法、试油资料折算法和试采法适合于M井区的单井产能预测。M井区长8储层合理的单井产量为3.5~4.0 t/d。研究成果为M井区长8储集层进一步开发奠定了重要的资料基础。

Abstract:

For the purpose of making rational single-well production programs for Chang 8 reservoir of M wellblock in Huanxian oil district area,Longdong and optimizing productivity of M wellblock,we performed a comprehensive study through integrating static geologic features of the reservoir such as lithologies,physical properties,oil-bearing properties with dynamic features like seepage flow patternss and production performance.Based on the geological data,core data,logging data and phase permeability data of the M wellblock,we carried out the research on reservoir characteristics,residual oil distribution and single-well productivity,and predicted the reasonable single-well production of this area.Chang 8 reservoir of M wellblock shows typical ultra-low permeability,significant logging response features and double wettability to oil and water.The reservoirs in M wellblock are structural-lithological reservoirs and the oil-water distribution is controlled by lithology.Oil-bearing properties are good in reservoirs with good poroperm characteristics along the main channel and in reservoirs on relative structural highs.Current production of M wellblock is mainly from southeastern-central part of M wellblock,with residual oil mainly occurring in the northern part and local southern-central part.The physical parameter method,test data conversion method and production test method are suitable for the prediction of single-well production in the study area.The rational single-well production is 3.5~4.0 t/d.These results provide important data-base for the further development of Chang 8 reservoir.
