海拉尔贝16井压裂合采原油分层产能的贡献

探井分层测试原油产能多数采用MFE技术等机械测量方法，但由于某些探井在分层测试与合采时使用了不同的求产方法，MFE技术等无法获得合采时的分层产能贡献，而搞清不同求产方法的分层产能状况，对于认识区域地层特征、增加产能等具有重要意义。海拉尔贝16探井压裂合采原油，采用烃指纹毛细管气相色谱检测技术、原油配比实验和数学模拟计算，测定了贝16井压裂合采所获得125t／d工业油流的3个分层贡献，为探井试油合采分层求产和原油开发动态监测分层产能状况、合理增产开辟了地球化学新方法。

Contribution of separate layer productivity of fractured commingled crude oil in Bei No.16 Well of Hailar Basin

Separate zone testing crude oil productivity in exploration wells mostly adopts some mechanical measuring techniques,such as,MFE technique.But,during the separate zone testing and commingle production,different production test is used in some exploration wells, because of MFE technique and other methods could not get the contribution of the separate zone productivity in commingle production.To know clearly about the separate layer productivity by using different production test plays a very important role in identifying regional geological characteristics,increasing productivity.Hydrocarbon fingerprint capillary gas chromatography detection technique,crude oil matching experiment and mathematical simulation calculation are used in fracturing commingle crude oil layers of Bei 16 Exploration Well in Hailar Basin.125t/d oil production from fractured commingled layer is determined in Bei 16 Well and the commercial oil flow is contributed from 3 subzones.A new geochemical method for exploration well production test,separate zone production test and the separate zone productivity detection in crude oil development dynamic monitoring and reasonable stimulating is set up.
