射孔压裂测试系统的管柱
摘要：
本发明公开了一种射孔压裂测试系统的管柱，其中，该管柱包括油管(9)以及依次设置在所述油管(9)上的射孔枪(1)、封隔器(3)、LPR-N阀(5)和RD安全循环阀(6)，所述射孔枪(1)、封隔器(3)、LPR-N阀(5)和RD安全循环阀(6)通过所述油管(9)彼此连通。该管柱进行一次下井作业就可完成整个射孔压裂测试过程，作业效率较高并且风险较低，操作简单方便，成本较低。
摘要（英）：

The invention discloses a tubular column of a perforation fracturing test system. The tubular column of the perforation fracturing test system comprises an oil pipe (9), a perforation gun (1), a packer (3), an LPR-N valve (5) and an RD safety circulating valve (6), wherein the perforation gun (1), the packer (3), the LPR-N valve (5) and the RD safety circulating valve (6) are sequentially placed on the oil pipe (9). The perforation gun (1), the packer (3), the LPR-N valve (5) and the RD safety circulating valve (6) are communicated with each other through the oil pipe (9). The tubular column of the perforation fracturing test system can finish the whole perforation fracturing test process by conducing down-well operation once, is high in working efficiency, low in risk, simple and convenient to operate and low in cost.
