摘要
在充分考虑海洋钻井平台特点、行业标准和用户要求的基础上,设计了DSJ300-1海洋钻井平台节流压井管汇。管汇布置采用倒L形结构,降低了阀门高度,方便操作、维修和维护;阀门采用比系统更高一级额定工作压力,为平台在不同海域、不同方位和不同水深作业时系统升级提供便利;阀门与四通、管线采用螺栓连接,提高设备的互换性;阀门与钢质垫环的密封槽采用堆焊不锈钢工艺,使设备具有抗H2S腐蚀的能力;采用双节流、双压井的冗余式结构,可利用高压钻井系统和固井系统的水泥浆进行压井作业,完成部分试井和试油工作。现场试验结果表明,该节流压井管汇具有可靠的井控功能,可保障平台作业人员和设备的安全。
On the basis of fully considering the features of offshore drilling platform, industrial standard and user demand, the throttling kill manifold of the DSJ300 - 1 offshore drilling platform was designed. The manifold layout adopts the inverted-L structure, reducing valve height. It is convenient in operation, repair and maintenance. The rated working pressure of the valve adopted is higher than that of the system, providing the convenience for sys- tem upgrading in different oceans, directions and water depths. The valve, cross tee and pipeline are connected by bolts, improving the interchangeability of equipment. The seal groove of valve and backing ring adopts surfacing stainless steel technology, enabling the equipment to resist against the HzS corrosion. The redundant structure of double throttling and double killing is adopted. The cement slurry of high pressure drilling system and cementing system can be used to conduct killing. The well testing and formation testing have been completed partially. The field test findings show that the manifold has the reliable well control function and it can guarantee the safety of plat- form operators and equipment.
