文昌13-1油田部分混采油井产能分配计算

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 CALCULATION OF THE OUTPUT PROPORATION OF MULTI-OIL ZONE CO-RECOVERY WELLS IN WENCHANG 13-1 OILFIELD

The output proporation of four multi-oil zone co-recovery wells in Wenchang 13-1 oilfield has been calculated based on highly accurate and repeated technology of Gas Chromatography (GC) for quantitative analysis on fingerprinting crude oil, random GC fingerprint differentia selection, the most similarity of GC fingerprint in the same oil zone, the most differentia of GC fingerprint among the different oil zones, and numeric simulation program of least square method. Through the method of "back to back", namely on-site testing and laboratory calculation going on respectively, the results of on-site testing and laboratory calculation have been compared, and having evaluated the creditability of the method. The absolute difference of two oil zone co-recovery well is about 5%, while that of three oil zone co-recovery well between 5%~10%.
