摘要
大港油田港西四区非均质性严重，水窜现象明显，聚合物驱油利用率仍需提高。根据这些特点，应用先进的交联聚合物防窜驱油渗流理论，考虑实验区地质、开发现状，建立选择防窜井的原则和方法，提出优化的交联聚合物防窜驱油方案，确定了各种因素对防窜效果的影响。理论研究与实施效果表明，交联聚合物防窜驱油模拟器在油田经营过程中起着重要的决策性作用，交联聚合物防窜驱油比单纯聚合物驱油的效果更好。交联聚合物防窜具有主动控制的特点。
In oil reservoirs there edest heterogeneity, obvious water channeling or polymer channeling in oil displacement by polarer inoil field development. How to improve water flooding or polymer flooding with cross-linking polymer is very important. Inthis paper, the authors use the porous now theory of cross-linking polymer flooding. Based on the geology and developmentcondition in Gangal No. 4 area, the principle and method of selecting well for cross-linking polymer to control channeling areestablished. The optimized injection scheme in test area is given. The various effect factors on the cross-linking polymerflooding to control channeling are defined. The study results show: ① The cross-linking polymer flooding compositionalsimulator for channeling control can act on an important policy decision in oil field management. ② The recovery efficiency ofcross-linking Polymer flooding for channeling control is higher than the polymner flooding. ③ By using the cross-linkingpolymer flooding to control channeling, polymer utilization efficiency is increased. ④ The cross-linking polymer floodingtechnique is an effective control technique.
