1991年5月1日，特立尼达岛东部海域的派立肯（Pelican）平台发生了地下井喷，经过16天的紧张工作，终于压住了井喷。由于两口井的间距太近，A－7井的钻井作业钻头钻透了A－4X井的套管和油管，造成了地下井喷。为了压住井喷。从美国迅速运来了压井的强行下钻设备。对井喷进行模拟，根据模拟模型制定计划。同时，把A－4X井立即投入生产，以减少地下自喷量。避免形成喷火口。进行压力、温度等为数据分析，确定地下井喷的油气位置，制定出切实可行的压井计超。经过强行下钻等压井作业，终于压住了井喷。避免了生命财产的重大损失。
On May 1, 1991, an underground blowout took place on the Pelican platform in the eastern part of Trinidad Island. After 16 days of intense work, it finally suppressed the blowout. As the spacing between the two wells was too close, the A-7 well bit was drilled through the casing and tubing of the A-4X well, resulting in an underground blowout. In order to suppress the blowout. Rapidly drilled kill rigs from the United States. Blowout simulation, according to the simulation model to develop plans. At the same time, wells A-4X were immediately put into production to reduce underground spray volume. Avoid forming a spout. Pressure, temperature, etc. for the data analysis to determine the location of underground blowout oil and gas to develop a viable surge meter super. After forced drilling and other kill operations, finally suppressed blowout. Avoid significant loss of life and property.
