玻璃钢套管井在羊三木油田稠油油藏开发监测中的应用

The application of fiber glass cased well in the development of heavy oil reservoir.

方法在目的层下入玻璃钢套管，代替常规钢套管。目的避免因磁性干扰而产生监测误差大的现象，利用玻璃钢套管导电性差的原理，应用感应测井、介电测井、声波测井及放射性测井等，达到周期性定量评价水淹程度和剩余油饱和度的目的。结果对大港油区羊三木油田三断块馆二上油组常规稠油油藏两口玻璃钢套管井进行监测，经取心和测井资料分析，对主流线水淹层及分流线的剩余油进行定量评价，并研究了剩余油分布特征，指出了潜力方向。结论用玻璃钢套管代替常规钢套管，进行系列测井，主要测试结果与密闭取心分析结果具有较好的一致性，说明利用该技术能准确监测油层动用状况；充分利用高频电测和电阻率系列综合测井。

Method\ Fiber glass casing is run to objective formation instead of conventional one. Purpose\ To avoid monitoring error caused by magnetic interference. Taking the advantage of poor electrical conductivity of fiber glass casing, evaluate seriousness of water-out and residue oil saturation periodically by using induction logging, dielectric logging, acoustic logging, radioactive logging, and etc. Result\ Two fiber glass cased wells, which are producing conventional heavy oil in Guan 2 upper oil formation of Yang 3 Mu 3 fault block of Dagang oil province have been monitored and observed. After coring, analyzing logging data, quantitatively evaluating residue oil in divisional watershed line and water-out formation of main watershed line, the potential development orientation is pointed out. Conclusion\ Main test results of serial logging with fiber glass casing are well concerted with analyzing results from sealing core drilling. It illustrates that this technique can accurately monitor oil bearing formation development degree. Fully utilizing high frequency E-logging and comprehensive resistance logging can fulfil periodically quantitative evaluation of water-out conditions and residue oil saturation of oil bearing formation. \;
