塔河油田11区开发过程中采用地质、地球物理和油藏动态综合研究方法,划分出溶洞型碳酸盐岩油藏存在高产稳产井、低产稳产井、低效井和空井4种典型。分析各类井钻遇储集体的地球物理识别特征和具有的油藏动态特征,提出开发方案设计中优先部署高产稳产井、其次是低产稳产井、最大限度地避免低效井和杜绝空井。开发实践证实,提高钻井成功率和开发经济效益十分显著。

Four kinds of typical wells,namely paying,stripped,deficient,and barren wells are recognized in the Block 11 of Tahe oilfield through integrated research of geology,geophysics,and reservoir dynamics.A development plan,which gives first priority to paying wells followed by stripped wells,minimizes deficient wells and eliminates completely barren wells,was proposed based on an analysis of the specific geophysical features and performances of the reservoirs encountered by these wells.The practice shows that the plan is quite effective in improving drilling success ratio and economic returns.
