Detection of leakage characteristics of natural gas under sea floor based on deposition method

为深入研究海底天然气渗漏活动特征,目前使用的检测方法主要是天然气水合物渗漏预警法,但该检测方法成本较高,且精度较低。针对此问题,设计基于沉积法的海底天然气渗漏活动特征检测方法。投放小型移动式观测平台,确定海底天然气渗漏位置。使用沉积法,测定天然气水合产物化学成分。分析沉积物物理特征,确定天然气渗漏活动特征。通过实验,证实基于沉积法的海底天然气渗漏活动特征检测方法更具经济性,检测精度更高。

In order to deeply study the characteristics of submarine natural gas leakage,the most commonly used detection methods are mainly the early warning method of natural gas hydrate leakage,which needs to measure high cost and low accuracy.To solve this problem,a detection method of submarine natural gas leakage activity characteristics based on sedimentation method is designed.Launch a small mobile observation platform to determine the location of submarine natural gas leakage,the chemical composition of natural gas hydration products was determined by deposition method.To analyze the physical characteristics of sediments and determine the characteristics of natural gas leakage activity,through experiments,it is proved that the detection method of submarine natural gas leakage activity characteristics based on deposition method is more economical and has higher detection accuracy.
