摘　　要：针对我国深海油气田勘探开发的需求,设计并制造了深海桶形基础安装设备样机,在保证安装设备耐压、密封等前提下,要求设备尺寸及质量尽量小,并能良好工作。对设计的样机进行了15 MPa高压试验,高压试验中采用了与南海相类似的沙子来模拟实际应用环境。试验结果表明:桶形基础实现沉贯,下降位移为11.23 mm,位移精度为1 mm;下降过程桶形基础基本稳定,X轴最大倾角为-1.24°,Y轴最大倾角为0.91°,倾角精度为0.1°,满足技术指标要求。Combined with the needs of exploration and development of deep-sea oil and gas fields in China,deep-sea bucket foundation installation equipment prototype was premised and manufactured.In the premise of ensuring the pressure,sealing,the size and the mass of the prototype was required to be minimized,and the function of the prototype was ensured to be proper. By using the similar geological sand materials of the South China Sea,15 MPa high pressure test of prototype was finished to ensure that the equipment might work in the deep sea environment.Experimental data was recorded and summarized as follow：penetration function of the bucket foundation is realized with the displacement of 11.23 mm and the displacement accuracy is as 1 mm.The maximum inclination of X axis is as-1.24° and the maximun inclination of Y asis is as 0.91° and the inclination accuracy is as 0.1°.The experimental processes are stable and meet the technical requierments.
