The damage degrees of different closure pressure, embedment or not of the proppant and the fracturing fluid with different dosage and concentration to the flow capacity of the proppant - packed fractures were investigated.

结合胜利油区低渗透油藏的特征,运用FCES-100裂缝导流仪,进行了支撑剂充填裂缝长期导流能力实验,考察了不同闭合压力、支撑剂嵌入与否、不同浓度和用量的压裂液对支撑剂充填裂缝导流能力的伤害程度,分析了各种因素对导流能力的伤害机理。

The efficiencies of closure pressure and fracturing fluid in the reservoir are accurately obtained by using the new method, with which the main fracture design is made, proper proppant volume and total fracturing fluid volume are designed with successful field application.

利用新方法可以准确求取储层的闭合压力和压裂液效率 ,据此进行的主压裂设计 ,设计合理的支撑剂体积与总压裂液体积 ,现场施工取得了成

However, without voltage blocking for the bus protection, it leads to weak anti-interference capability in 3/2 circuit breakers connection.

500千伏系统的母线保护可靠性很重要,但是一个半断路器主接线方式的母线保护不实施电压闭锁,造成了抗干扰能力差。

The feasibility and universality of the voltage blocking release approach is explained,which uses the AND logic of protection active and breaker current existence.

分析了失灵保护在实际运行中存在的如保护动作启动失灵保护的继电器不能快速返回、电压闭锁不能可靠开放及电流判别元件灵敏度不足等一些问题,阐述了“保护动作”和断路器“有流”的“与”逻辑解除电压闭锁方案的可行性和通用性,提出了失灵电流判别元件的定值及逻辑应采用“无流鉴别”元件的原则。
