【摘要】：油管懸掛器作為水下采油樹系統(tǒng)的核心設(shè)備,其能否安全可靠的工作關(guān)系到深水石油開發(fā)的成敗。本文根據(jù)海洋深水石油開發(fā)的作業(yè)要求,開展油管懸掛器的設(shè)計研究,早日突破關(guān)鍵技術(shù)阻礙,實現(xiàn)水下采油樹系統(tǒng)的國產(chǎn)化。依據(jù)API相關(guān)規(guī)范,在對比國外產(chǎn)品特點的基礎(chǔ)上,提出一套總體研究方案,詳細闡述了深水下放安裝作業(yè)流程,對油管懸掛器主體結(jié)構(gòu)、鎖緊結(jié)構(gòu)、密封結(jié)構(gòu)、電液通道布局進行了詳細設(shè)計,完成了主體結(jié)構(gòu)的校核和鎖緊環(huán)的受力分析,并對油管懸掛器下放工具進行了概念設(shè)計,運用SOLIDWORKS建立油管懸掛器及其下放工具的三維模型。完成了核心部件材料的選取,運用有限元軟件ABAQUS對主體結(jié)構(gòu)座放臺肩、鎖緊結(jié)構(gòu)、卡簧、下放工具鎖緊環(huán)進行了強度分析。密封技術(shù)是水下石油裝備的關(guān)鍵技術(shù),因此本文著重對油管懸掛器密封技術(shù)和密封性能進行了研究。分析了國外石油裝備公司的的密封技術(shù),對國外不同公司產(chǎn)品的技術(shù)特點進行了總結(jié),并對其各項性能指標進行比較。通過對密封關(guān)鍵技術(shù)的分析,指出高溫、高壓、強腐蝕環(huán)境下油管懸掛器密封的發(fā)展方向是新材料和新型密封結(jié)構(gòu)。以金屬密封結(jié)構(gòu)為研究對象,建立了油管懸掛器密封的力學(xué)分析模型和材料模型,對兩種不同接觸面形式圓弧形接觸面(密封Ⅰ)和傾斜接觸面(密封Ⅱ)的密封性能進行分析,在ABAQUS軟件中建立的有限元模型,通過改變密封的過盈量、壓力載荷、溫度載荷、彈性模量四個變量來分析金屬密封圈最大Mises應(yīng)力、最大接觸壓力及接觸壓力在接觸面上的變化情況,從而對密封在不同工況下的性能進行分析。對彈性體密封在不同壓縮率下的Mises應(yīng)力和接觸壓力進行了有限元仿真,完成了密封結(jié)構(gòu)的性能分析。最后對全文進行了總結(jié),并展望了立式油管懸掛器下一步的研究工作。
[Abstract]:As the core equipment of the underwater oil production tree system, the oil pipe hanger is the key equipment of the underwater oil production tree system. It is related to the success or failure of the deepwater oil development. In this paper, according to the requirements of the offshore oil development, the design and research of the oil pipe hanger are carried out, the key technical obstacles are breakthroughs and the localization of the underwater oil recovery tree system is realized. According to the API phase On the basis of comparing the characteristics of foreign products, a set of overall research scheme is put forward, and the installation process is elaborated in detail. The main structure of the hanger, the locking structure, the seal structure and the distribution of the electrohydraulic channel are detailed. The checking of the main structure and the force analysis of the locking ring are completed, and the suspension of the oil pipe is suspended. The concept design of the hanger tool is carried out. The three-dimensional model of the oil pipe hanger and its lower instrument is set up by SOLIDWORKS. The selection of the core components is completed. The strength analysis is carried out by using the finite element software ABAQUS to carry out the strength analysis of the main structure seat, the locking structure, the lock spring and the lower tool lock ring. In this paper, the sealing technology and sealing performance of the oil pipe hanger are studied in this paper. The sealing technology of foreign oil equipment company is analyzed. The technical characteristics of the foreign products are summarized and the performance indexes are compared. Through the analysis of the key seal technology, the high temperature and high temperature are pointed out. Under pressure and strong corrosion environment, the development direction of the seal of oil pipe hanger is new material and new seal structure. The mechanical analysis model and material model of the sealing structure of the tubing hanger are established. The sealing properties of the circular arc contact surface (seal I) and the inclined contact surface (seal II) of two different contact surfaces are established. The finite element model established in the ABAQUS software is analyzed. The maximum Mises stress, the maximum contact pressure and the contact pressure on the contact surface are analyzed by changing the interference amount of the seal, the pressure load, the temperature load and the modulus of elasticity, and the performance of the seal under the different working conditions is analyzed. The finite element simulation of the Mises stress and contact pressure of the elastomer under different compression rates is carried out. The performance analysis of the sealing structure is completed. Finally, the full text is summarized and the research work on the next step of the vertical tubing hanger is prospected.
