深水测试管柱力学行为研究进展及发展方向

深水测试管柱的力学行为对深水测试的成功有着重要的影响。以陆地管柱力学研究为基础，对深水测试管柱
的结构、工况、载荷以及研究现状进行了分析阐述。分析认为，国外深水测试技术成熟，深水测试管柱力学行为研究完
善；而国内则主要依靠国外技术服务公司进行深水油气田的测试工作。同时，针对中国深水测试的应用现状，对深水
测试管柱的力学行为研究进行了系统分析，指出应该建立考虑平台升沉和漂移、隔水管影响、产层高压流体、射孔冲击
载荷、温度耦合作用等因素的深水测试管柱动力学模型，分析整个管柱的力学行为，实现对深水测试管柱的优化设计，
提高深水测试管柱施工作业的安全可靠性。

The Status and Development in Mechanical Behavior of Deepwater Well-testing Strings

The mechanical behavior of deep water testing string has an important influence on the success of the deep water
test. Based on the study of the ground pipe string mechanical，the structure，working condition，load and the research status of
the deep water testing string are analyzed and expounded. According to the result of the analysis，the test technology overseas
is mature and the study of mechanical behavior of the deep water testing string is consummate. However，the test work of deep
water field is mainly carried out by foreign technology service company. Aiming at the application status of deep water test in
China，the mechanical behavior of the deep water testing string is analyzed systematically. The conclusion shows that a dynamics
model of deep water testing string could be built，considering the heaving and drifting of platform，the high pressure fluid of
pay formation，the impact of perforation，the temperature coupling effect and other factors. For the purpose of optimization
design of deep water testing strings，and improvement of safety reliability of construction work of deep water testing string，
the mechanical behavior of the whole string should be analyzed.
