摘　　要：精细试油是油气藏勘探中准确评价储层的一项重要手段,但在同一管柱内完成分层射孔、分层独立试油还难以实现。在陆上探井和海洋完井项目中,尤为重视针对不同井况采用不同策略进行一次性射孔测试联作完井,这项技术可缩短试采周期并节约作业成本。介绍了一种新型射孔测试联作技术,在不动管柱、不循环压井的条件下,利用一趟管柱实现了不同层位间的独立精细试油,试油周期短、成本低,测试信息准确,为油气田勘探精细评价提供了新思路。Fine production testing is an important means to accurately evaluate reservoirs in oil and gas exploration,but it is difficult to complete separate layer perforation and production testing in one trip string.In the onshore exploration well and offshore completion project,it is particularly important to adopt different strategies for one-time perforation combined well testing and completion according to different well conditions.This technology can shorten the production testing cycle and save operation cost.This paper introduces a new perforating testing combined technology.Under the condition of no moving string and no circulating well killing,the independent fine production testing between different layers is realized by using one trip string.The testing period is short,the cost is low,and the testing information is accurate.It provides a new idea for the fine evaluation of oil and gas field exploration.
