按照同层原油指纹最大相似性和 异层原油指纹最大差异性原则，运用高精度再现全油色谱指纹分析技术和随机差异色谱指纹 筛选法以及最小二乘法拟合软件，确定了文昌13\|1油田4口混采油井产能分配方案。采用现场测试与实验室计算“背靠背”方法分别对4口井进行产能分配，然后通过对比各自的分配 结果来评价两种方法的可行性和可信度。结果表明两层混采油井各单层出油量绝对误差约5% ，三层混采油井各单层出油量绝对误差介于5%～10%之间。

The outp ut proporation of fo ur multi-oil zone co-recovery wells in Wenchang 13-1 oilfield has been  calculated based on highly accurate and repeated technology of Gas Chromatograp hy (GC) for quantitative analysis on fingerprinting crude oil, random GC fingerp rint differentia selection, the most similarity of GC fingerprint in the same oi l zone, the most differentia of GC fingerprint among the different oil zones, an d numeric simulation program of least square method. Through the method of “bac k to back”, namely on-site testing and laboratory calculation going on respect ively, the results of on-site testing and laboratory calculation have been comp ared, and having evaluated the creditability of the method. The absolute differe nce of two oil zone co-recovery well is about 5%, while that of three oil  zone co-recovery well between 5%~10%.
