Quite a few specialists and scholars have studied the damage mechanism and protective technologies, but it is all relatively scattered.
不少专家、学者对射孔损害机理和保护技术也进行了研究,但都比较零散,比较系统地总结了他们的研究结果。This would be valuable as a direction for the drilling operation and the perforation program at the untapped peripheral areas.
这对外围油田未开发区块的钻井运行及射孔方案编制具有一定的指导价值。Applied results show that the scheme is one of correct perforation-completion methods for developing such low permeable gas field.
应用效果证明该方案是对低渗透气田开发的一种正确的射孔完井方法。The upper and bottom sound filters may limit propagation direction of pressure surge, forcing it concentrated on the perforated interval.
上下滤声器可以限制压力波动的传播方向,使其集中在射孔段处。It diagnoses channeling out of casing and perforates holes expecting to perforate intervals when gas exists in the reservoir.
在储层含气时,用于判断套管外是否窜槽、射孔井段是否已正确射孔。The characteristics and placement of the communication paths (perforations) can have significant influence on the productivity of the well.
连通通道(射孔孔眼)的特性和位置会对井的产能产生重大影响。Containing several shaped explosive charges, perforating guns are available in a range of sizes and configurations.
射孔枪包含几个聚能射孔弹,并有各种直径和结构。Formulation of the perforating acid depends on the characteristics of the formation and the downhole equipment used.
射孔酸的组成取决于地层特性和所用的井下设备。Squeeze cementing operations may be performed to repair poor primary cement jobs, isolate perforations or repair damaged casing or liner.
挤水泥作业可用于修补初次注水泥作业留下的缺陷、隔离射孔孔眼或修理损坏的套管或衬管。
