【摘要】：近年来,水下生产系统已经逐渐成为深海石油勘探开发的关键设备。我国在海洋水下井口及采油装备的技术研究方面起步较晚,在整个水下生产系统的设计、制造以及维修等方面,还处在空白状态。随着中海油开发南海深海和各油田边际石油资源,作为水下生产系统最重要的组成部分,水下采油树及其相关设备越来越广泛的应用于海洋石油生产,其维修保养和安全运行的工作将越来越重要。因此,本文选定“水下采油树系统地面测试单元研究”作为研究课题,具有重要的理论意义和工程应用价值。本文围绕该课题开展了深入的理论与试验研究工作,并取得了如下的研究成果:(1)提出了一种水下采油树系统测试方法。通过查阅国内外相关资料和文献,研究了国内外水下采油树的结构及工作原理,重点分析了流花11-1油田水下卧式采油树,并在此基础上,通过参考国内外相关标准、文献以及水下采油树FAT(Factory Acceptance Test)、SIT(System Integration Test)等测试资料,针对流花11-1油田水下卧式采油树提出了水下采油树系统测试方法,该测试方法具有很好的扩展性,可适用于其他类型的水下采油树。(2)研制了一套水下采油树系统地面测试单元样机,包括液压控制系统和电控系统。液压控制系统包括油箱、高压泵回路、水泵回路、蓄能器组、调压回路、回油回路以及接口回路等。电控系统以西门子S7-300系列PLC作为下位机,以WinCC组态软件作为上位机进行了开发。(3)开展了水下采油树系统地面测试单元测试以及应用验证工作。测试的目的是了解整机的性能是否满足设计要求,包括关键部件动作状况检测、测量仪器检测以及液压管线压力试验。应用验证的目的是验证地面测试单元是否能够完成水下采油树系统的测试,包括液控阀测试、采油树连接器测试以及采油树液压管线测试。结果表明使用本测试单元能够准确判断水下采油树系统的各种情况,完成水下采油树系统的测试,应用效果良好。
[Abstract]:In recent years, underwater production system has gradually become the key equipment for deep-sea oil exploration and development. Our country started late in the technical research of offshore underwater wellhead and oil recovery equipment, and is still in a blank state in the design, manufacture and maintenance of the whole underwater production system. As CNOOC exploits the marginal oil resources in the deep sea and various oilfields in the South China Sea, as the most important component of the underwater production system, the underwater oil production tree and its related equipment are more and more widely used in offshore oil production. Its maintenance and safe operation work will become more and more important. Therefore, this paper chooses "study of ground Test Unit of underwater Oil recovery Tree system" as the research subject, which has important theoretical significance and engineering application value. In this paper, a deep theoretical and experimental study is carried out around this subject, and the following research results are obtained: (1) A test method for underwater oil recovery tree system is proposed. The structure and working principle of underwater production tree at home and abroad are studied by consulting relevant information and literature at home and abroad, and the underwater horizontal oil recovery tree of Liuhua 11-1 oilfield is analyzed emphatically, and on this basis, by referring to the relevant standards at home and abroad, Based on the literature and test data of Factory Acceptance Test (fat) / sit (system Integration Test), a test method of underwater oil recovery tree system in Liuhua 11-1 oilfield is proposed, which has good expansibility. It can be applied to other types of underwater oil production tree. (2) A prototype of ground test unit for underwater oil extraction tree system is developed, including hydraulic control system and electric control system. The hydraulic control system includes oil tank, high pressure pump circuit, accumulator group, regulating circuit, return oil circuit and interface circuit. The electric control system is developed with Siemens S7-300 series PLC as lower computer and WinCC configuration software as upper computer. (3) ground test unit test and application verification of underwater oil production tree system are carried out. The purpose of the test is to find out whether the performance of the whole machine meets the design requirements, including the detection of the movement status of the key components, the measurement of measuring instruments and the hydraulic pipeline pressure test. The purpose of application verification is to verify whether the ground test unit can complete the test of underwater oil production tree system, including hydraulic valve test, oil tree connector test and oil tree hydraulic pipeline test. The results show that the test unit can accurately judge the various conditions of the underwater oil recovery tree system, and complete the test of the underwater oil production tree system, and the application effect is good.
