摘要
本文对国外发表的若干计算流体物性参数的相关式进行了考察,以验证这些相关式在大庆油田的适用性。采用138个PVT实验数据,对常用的计算R_a、P_b、p_0、Z、B_u信的相关式作了精度预测,并根据AAPD和SD最小值给出了最佳相关特性。最后,应用最佳相关式实际处理了生产测井资料,并取得了较好效果。
This paper examines some correlation formulae published in foreign literature,which are used to calculate fluid physical parameters so as to determine their applicability in Daqing Oil Field. Correlation formulae commonly employed to calculate R_s,P_b,po,Z,B_o are estimated with 138 PVT test results. The optimal correlation is given in accordance with the minimum value of AAPD and SD. Examples are given for the application of the optimal correlation technique in data processing of production logs.
