大庆油田A区块油气水层解释标准研究

Study on explanation standard of oil's gas and water layers of A block in Daqing Oilfield

利用A区块部分探井、评价井及开发井的试油、取心及测井资料,分析统计储层岩性、物性、含油性及电性这"四性"之间的关系,建立油气水层的电性解释标准。主要是利用旋转式井壁取心及钻井取心资料,分析统计储层的岩性、物性特征;利用取心井及试油井资料分析统计储层的油水层发育状况。利用图表法,得出岩性、物性及含油性之间的相关性。并把油气水层对应于不同的测井曲线值上,优选出符合率最高的曲线组合作为最终的解释标准,指导区块射孔方案的编制。

By using testing, coring and logging data of part exploratory well, evaluation well and development well in A block, we analyzed and counted the relation of ＂four characters ＂,that is lithology, physical character, oil-bearing and resistivity , and established the explanation standard of oil, gas and water layers. Mainly using data of rotatory sidewall coring and drilling well coring, we analyzed and counted reservoir lithology characters and physical properties ; by using coring wells and testing oil wells, we analyzed and counted the growth condition of oil and water layers. By using data of charts method, we got the correlation of lithology, physical character and oilbearing. Oil, gas and water layers were corresponding to different logging curve values and the curve with the highest coincidence rate was chosen as final explanation standard to direct the block perforation program.
