泌304区整体压裂裂缝参数优化研究

Optimization of Overall Fracturing Fracture Parameters in Well Block B304

根据泌阳凹陷泌304区油藏地质特征及开发要求,以泌304区整个油藏作为研究对象,采用油藏数值模拟方法,结合正交试验设计与模糊综合优化决策方法,优化出泌304区最佳水力裂缝缝长60～75m,最佳导流能力0.45～0.50μm2.m。现场应用取得了较好的开发效果,为泌304区整体高效开发提供了技术保证。

According to oil reservoir geology features and development requirements of Well Block B304 in Baying Depression,the overall reservoir in Well Block B304 was deployed as the object of study,based on numerical simulation calculations,orthogonal experiment and fuzzy optimized decision were used to optimize the best length of hydraulically created fracture as 60~75 m,and best flow conductivity 0.45~0.50μm2·m. Good effect is achieved in field application and it provides technical support to a high efficient development in Well Block B304.
