摘　　要：针对元坝探区高压气井射孔酸压测试三联作施工中存在封隔器串通失效、压井液气浸、管柱埋卡等问题进行分析研究,通过改进封隔器结构、控制施工压差、改变压井方式、优化测试管柱和施工工艺,减少了施工过程中井下复杂情况的发生,提高了测试成功率和施工安全。现场应用31口井49井次,测试成功率达98%,取得了良好效果。According to problems of packer collusion failure,gas influx of killing fluid,stuck and buried of testing string existing at three combination operation of perforation,acid fracture and DST in the high pressure gas well of Yuanba area,analysis and study has been conducted. Through improving the packer structure,controlling the testing pressure difference,changing the manner of killing well,optimizing testing string and operation process,the down hole complicated conditions occurs in the operation process are reduced to improve the test success rate and safety. Field applied in 49 well times of 31 wells,success rate is 98%,and good results are achieved.
