摘要:
为了解决海洋平台井喷事故发生后井口压力与井喷液柱高度的获取问题，基于观测船船体三自由度运动，提出1种井喷液柱高度测量方法。在考虑船体三自由度运动的前提下，将难以直接测量的井喷液柱高度转化为三倾角测量，再通过设计的配套液柱高度计算方法计算液柱高度；采用自设计新型角度测量装置测量角度；对角度测量信号进行卡尔曼滤波处理，消除甲板振动对测量的影响，并优化设计测点间距，进一步提高测量精度。研究结果表明：在考虑不同船体状态的情况下，测量值与实际值误差小于4.2%，该测量方法可行，整体设备简单、操作方便、稳定性高、适应能力强，计算结果准确，可以满足现场应用需求。
Abstract:
In order to solve the problem of obtaining the wellhead pressure and liquid column height of blowout after the occurrence of blowout accident on the offshore platform, a measurement method for the liquid column height of blowout was proposed based on the three degrees of freedom motion of the observation vessel. Under the premise of considering the three degrees of freedom motion of vessel, the liquid column height of blowout being difficult to measure directly was converted into the three dip angle measurement, then the liquid column height was calculated through the designed matching calculation method of liquid column height. The selfdesigned new angle measuring device was applied in the angle measurement. The Kalman filter processing was carried out on the angle measurement signals to eliminate the influence of deck vibration on the measurement, and the spacing of measurement points was optimally designed to further improve the measurement accuracy. The results showed that when considering different vessel conditions, the error between the measured value and the actual value was less than 4.2%, which proved the feasibility of the measurement method. The overall equipment was simple and easy to operate with a high stability and strong adaptability, and it could meet the requirements of field application.
