摘　　要：高温高压井作业一直是石油行业公认的作业难点之一,由于其苛刻的温压环境,使得常规井作业中的工具难以适应,常常由于工具失效而引发一系列工程事故。测试作业更是高温高压井作业中一个高风险部分,之前海上高温高压测试工艺存在插入密封下插困难、环空温度、压力变化影响工具正常操作等问题,作业条件受限。在"安全第一"的作业理念下,随着技术的进步,作业经验的不断积累,通过RD旁通试压阀和选择性测试阀的配合使用使得现行工艺越来越完善,解决了目前高温高压井测试工艺中存在的局限,有利于更好地达到测试的地质目的。于是一种新的高温高压测试工艺在实践中形成。The normal tool is hard to adapt the HPHT well operation and cause a series of accidents frequently. Testing is a high- risk part in the HPHT well operation,the previous testing technology has restricted by many aspects,for example the difficulty of inserting to the seal bore of eternal packer and influence of testing tool operation by the raising of temperature and annular pressure. Under the 'safety first'philosophy,along with advances in technology and operational experience gained,using RD bypass valve and selectivity testing valve makes the current testing technology more perfect. The improvement solved the restriction of the current testing technique and achieved the geology testing requirement in HPHT well.
