- 摘要:
- 深水高压气田开发面临的主要挑战之一，是如何应对高关井压力带来的超压工况下低压生产设施的安全保护问题。HIPPS作为一种高完整性的压力保护系统，具有反应快、安全性高、项目整体投资低的特点，已逐步应用于我国深水高压气田开发领域。在具体分析HIPPS基本配置、功能要求、水下和依托平台安装方案优缺点的基础上，采用HYSYS工艺模拟软件，对装有HIPPS的南海深水气田群项目番禺35-1段塞流捕集器，在超压工况下容器内部压力上升过程进行动态模拟。研究表明：对于深水高压气田，合理使用HIPPS可有效地提高生产安全性，降低项目整体投资；应在操作维修可行性、安全性、成本等方面对HIPPS的安装位置进行综合评估；HIPPS双关断阀SDV的压力高高值PSHH设定值建议比紧急关断阀ESDV压力高高设定值高3％，比低压系统安全阀PSV设定值低2%。
One of main challenges in deepwater high pressure gas filed development is safety protection for deepwater low pressure production facilities and tie-in platform facilities under overpressure working conditions caused by high shut-in pressure. As a kind of high integrity pressure protection system, HIPPS has such characteristics as rapid response, high security and low investment and has been gradually used in domestic deepwater high pressure gas filed development. Analyzed are basic configuration and function requirements of HIPPS and its advantages and disadvantages in the case of underwater installation and platform installation and applied is HYSYS process software to dynamically simulate internal pressure rise process of Panyu 35-1 slug catcher equipped with HIPPS under overpressure working conditions in south China sea deepwater gas field group project. Research results show that for deepwater high pressure gas field, rational application of HIPPS can effectively improve the safety of production and reduce overall investment.
