荔湾3-1气田开发数值模拟研究

对荔湾3-1气田气藏流体高压PVT实验数据进行拟合计算，确定了适合描述气藏流体相态行为的流体组分特征参数。利用地质资料及研究成果所得到的地层物性参数，结合构造形态和井点信息，建立了相应的三维地质模型，完成气藏地质储量拟合。从井网部署、初期采气速度、气层动用秩序、断层的连通敏感性及最小井底流压敏感性等多方面对气藏的开发指标进行了数值模拟对比研究，所得的研究结论有利于指导该气田实际开发生产。

RESEARCH ON THE DEVELOPING NUMERICAL SIMULATION OF LIWAN 3-1 GAS FIELD

The PVT experimental data of Liwan 3-1 Gas Field with high fluid pressure is matched and the fluid component characteristic parameters are determined.According to the physical parameters determined by geologic study，the well location and the structure shape，a three-dimensional geological model is built.After the match of gas reservoir geologic reserves，in order to study the performance of development，the numerical simulation research of the gas reservoir is completed from the aspects of well pattern，initial gas production rate，order of development，the sensitivity of fault connection and the sensitivity of minimum BHP.The study results provide a reliable foundation for the gas field development.
