莫里青敏感性低渗透油藏压裂工艺技术

Moliqing Sensitivity of Low Permeability Reservoir Fracturing Technology

莫里青油田储层具有埋藏深、温度高、低孔低渗、水敏性强、岩石成熟度低的特征。为了提高压裂效果,主要从压裂过程中的储层保护和优化压裂设计两个方面进行研究。应用柴油和原油两套低伤害乳化压裂液体系、提高压裂液效率、合理的压后返排程序、优化射孔段、整体优化压裂设计等手段,获得理想的矿场施工效果,推动敏感性低渗透油藏压裂工艺技术的发展。

In Moliqing reservoir is buried deep, high temperature, low porosity and low permeability, strong water sensitivity, low maturity characteristics of rock. In order to improve the effect of fracturing, mainly from the fractured reservoir protection in the process and the optimization of fracturing design in two aspects of research. Application of diesel, two sets of low damage oil emulsified fracturing fluid system, improve efficiency of fracturing fluid, reasonable postfrac flowback procedures, optimizing perforation section, the overall optimization of fracturing design and other means, to obtain the desired field construction, promote the sensitivity of low permeability reservoir fracturing technology development.
