【摘要】：我國的海洋油氣勘探領(lǐng)域起步較晚,對(duì)于海洋石油裝備的開發(fā)能力較弱,近年來隨著海洋戰(zhàn)略的實(shí)施,我國海上油氣生產(chǎn)裝備進(jìn)入發(fā)展快車道[1]。水下生產(chǎn)系統(tǒng)是海上石油勘探的關(guān)鍵,而水下控制器則是整個(gè)水下生產(chǎn)系統(tǒng)的核心部分,它承擔(dān)著安全有效控制水下生產(chǎn)系統(tǒng)、保證海洋石油安全、可靠開發(fā)的重任。然而,國內(nèi)目前仍然沒有掌握關(guān)鍵技術(shù),更沒有成熟產(chǎn)品問世。因此,深海油氣田水下控制器的國產(chǎn)化研制,已經(jīng)迫在眉睫,成為我國發(fā)展水下生產(chǎn)系統(tǒng)進(jìn)程中必須盡快解決的重要課題。基于以上國內(nèi)現(xiàn)狀,本文對(duì)于水下控制器進(jìn)行了研究與開發(fā)。(1)本文對(duì)深海油氣田水下生產(chǎn)系統(tǒng)進(jìn)行了分析,對(duì)水下采油樹、水下控制器、臍帶纜等主要功能進(jìn)行了梳理。在對(duì)國內(nèi)外水下控制器研究現(xiàn)狀分析的基礎(chǔ)上,對(duì)深海油氣水下控制器進(jìn)行研究與開發(fā)。(2)本文首先對(duì)深海油氣田水下采油樹的工藝流程進(jìn)行研究,并對(duì)水下控制器的控制機(jī)理進(jìn)行分析。確定水下控制器的設(shè)計(jì)需求和控制功能。(3)本文對(duì)水下控制模塊(SCM)的硬件進(jìn)行設(shè)計(jì),并進(jìn)行輸入輸出點(diǎn)數(shù)統(tǒng)計(jì)、容量估算以及相關(guān)控制模塊的選擇。該水下控制器以PLC作為控制核心,通過電力載波技術(shù)實(shí)現(xiàn)基于電力線的通信功能,完成對(duì)采油樹各回路的邏輯控制、運(yùn)行監(jiān)視和故障報(bào)警等任務(wù)。(4)本文在最大限度滿足深海油氣田水下生產(chǎn)控制系統(tǒng)的生產(chǎn)要求的基礎(chǔ)上,進(jìn)行控制理論與控制方法研究,并完成控制器的軟件設(shè)計(jì),實(shí)現(xiàn)對(duì)于水下生產(chǎn)系統(tǒng)進(jìn)行穩(wěn)定、高效的遠(yuǎn)程自動(dòng)控制以及現(xiàn)場(chǎng)的手動(dòng)控制。SCM通過采集各類傳感器信息監(jiān)測(cè)系統(tǒng)的運(yùn)行狀態(tài),實(shí)現(xiàn)整個(gè)系統(tǒng)穩(wěn)定、安全、可靠、高效的運(yùn)行。(5)本文最后進(jìn)行基于King View的主控站人機(jī)界面的設(shè)計(jì),完成和水下控制器的對(duì)接,實(shí)現(xiàn)主控站對(duì)水下生產(chǎn)設(shè)備的監(jiān)控。該水下控制器已經(jīng)在美鉆能源科技(上海)有限公司投入運(yùn)行,運(yùn)行穩(wěn)定、可靠,具有良好的應(yīng)用前景。
[Abstract]:The field of offshore oil and gas exploration in China started late, and the development ability of offshore oil equipment is relatively weak. In recent years, with the implementation of marine strategy, China's offshore oil and gas production equipment has entered the fast track of development [1] .underwater production system is the key to offshore oil exploration, and underwater controller is the core part of the whole underwater production system, which is responsible for the safe and effective control of underwater production system. To ensure the safety and reliable development of offshore oil, however, there are still no key technologies or mature products in China. Therefore, the development of underwater controllers for deep-sea oil and gas fields is imminent. It has become an important subject that must be solved as soon as possible in the development of underwater production system in China. Based on the above domestic situation, the underwater controller is researched and developed in this paper. (1) the underwater production system of deep-sea oil and gas field is analyzed in this paper. The main functions of underwater oil recovery tree, underwater controller, cord cable and so on are summarized. Based on the analysis of the research status of underwater controller at home and abroad, Research and development of underwater controller for deep-sea oil and gas. (2) in this paper, the technological process of underwater oil production tree in deep-sea oil and gas field is studied. The control mechanism of underwater controller is analyzed. The design requirement and control function of underwater controller are determined. In this paper, the hardware of underwater control module (SCM) is designed, and the input and output points are counted. The underwater controller takes PLC as the control core, realizes the communication function based on the power line through the power carrier technology, and completes the logical control of each loop of the oil production tree. On the basis of meeting the production requirements of underwater production control system in deep-sea oil and gas fields to the maximum extent, the control theory and control method are studied, and the software design of the controller is completed. To realize the stability of underwater production system, efficient remote automatic control and manual control on the spot. SCM can realize the stability, safety and reliability of the whole system by collecting all kinds of sensor information monitoring system. In the end, we design the man-machine interface of the main control station based on King View, and finish the docking with the underwater controller. The underwater controller has been put into operation in the United States drilling Energy Technology (Shanghai) Co., Ltd., running stably and reliably, and has a good application prospect.
