塔河油田酸压净压力监测技术及应用

Tech of Net Pressure Monitoring for Acid and Fracture and Its Application in Tahe Oilfield.

酸压是塔河奥陶系强非均质碳酸盐岩油藏储层改造的主要手段,酸压过程中井下净压力值连续监测技术为该区酸压效果、工作液管程摩阻、井口泵注压力分析提供了可靠依据。该项技术是通过在酸压管柱中下入DPT井下压力计,进行井底压力和温度实时监测,将该项资料与井口监测压力组合分析,可实现不同工作液摩阻参数、酸压效果的系统评价。

Acid and fracture is the main manner to reform heavy heterogeneity carbonate reservoir of Ordovician system in Tahe oilfield. During this period, tech of continuous net pressure monitoring for acid and fracture provides an analyzed basis for fractured result, monitor friction resistance of working fluid, pumping pressure at well head. By inputting DPT down hole electronic gauge in acid and fractured string to measure pressure and temperature on real time and assembly analyzed this data with monitoring pressure at well head, systemic interpretation with different friction parameter of working fluid and acid and fracture result can be reached.
