白音查干油田油藏埋深浅,温度低。储层具有含油条带窄、油层单一、单层厚度小、小断层发育、断块小、油水界面不统一等特点。压裂改造存在压裂液破胶难、液体返排率低、效果差等难点。对此开展了低温压裂液体系、压裂设计优化及施工参数优化等研究工作,形成了适合白音查干浅油层的系列低温压裂液体系及压裂设计优化技术,经现场应用取得了显著的增产效果。
Baiyinchagan oilfield buried shallow depth, low temperature. The reservoirs have the characteristics of narrow oil-bearing strata, single oil layer, small single-layer thickness, small faults, small fault blocks and nonuniform oil-water interface. Fracturing fluid fracturing fluid fracturing difficult, liquid flow rate is low, the effect is poor and other difficulties. A series of researches on low temperature fracturing fluid system, optimization of fracturing design and optimization of construction parameters were carried out, and a series of low temperature fracturing fluid systems and fracturing design optimization techniques suitable for Baiyincha dry oil reservoir were developed. Significant stimulation effect.
