Abstract

Abstract: The stress field prediction software for refractured oil wells was developed,considering the existence of initial hydraulic fractures and impact of oil production and water injection on initial stress field.This software was applied to seven wells in Xinzhan Oilfield,and the four ones of them were selected to be refractured.In the treatment of these wells,micro-seismic and tilter meter were used to monitor the fracture spreading.After refracturing,the production histories of oil wells were matched with numerical simulation.The results showed that the reorientation of fractures occurred in the refractured wells,which confirmed the validation of the prediction software.

Key words: refractured well, fracture spreading, stress field, history matching, prediction software

摘要： 综合考虑初次裂缝的存在以及油气井的生产对原应力场的影响,研制了重复压裂前地应力场的预测软件。运用该软件考察了新站油田7口井重复压裂前的地应力场,对其中4口可能发生重复压裂裂缝转向的井实施了转向重复压裂。在现场施工中,用地面测斜仪监测了裂缝的形成和扩展过程,压裂后用数值模拟方法拟合的各井生产历史动态表明,试验井发生了重复压裂裂缝转向,证实了地应力场预测软件的有效性。
