【摘要】：由于油氣資源的消耗逐日遞增,且常規(guī)油氣田的發(fā)現(xiàn)在逐漸減少以及傳統(tǒng)油氣產(chǎn)區(qū)的開采難度加大,從海洋中開發(fā)新的油氣資源成為一項非常重要的部署。因此提高海洋鉆井設(shè)備配置,提高鉆井效率尤為重要。目前大多數(shù)海洋鉆井平臺配備頂驅(qū)系統(tǒng),實現(xiàn)立根鉆井從而減少接卸鉆桿時間以提高鉆井效率。但是由于井架內(nèi)部狹窄空間的限制,很難配備相應(yīng)的鉆桿排放裝置和單根接立根裝置。因此探索一種能夠增加平臺鉆井空間的方案、設(shè)計適應(yīng)于已安裝頂驅(qū)的鉆井平臺接立根裝置是相當(dāng)重要的。本文在調(diào)研海洋平臺結(jié)構(gòu)、鉆修機及離線接單根作業(yè)現(xiàn)狀的基礎(chǔ)上,結(jié)合海洋鉆修機井架類型,設(shè)計出了一種可用于K型井架的離線接單根裝置,同時根據(jù)鉆臺結(jié)構(gòu)和裝置分布,提出通過外接外掛平臺來增加鉆臺面面積的方法。在完成外掛平臺安裝可行性分析的基礎(chǔ)上,完成了外掛平臺及離線接單根裝置安裝位置選取、功能分析以及方案選型等工作,設(shè)計了離線單根接立根工藝流程,并完成了外掛平臺、管柱移運裝置結(jié)構(gòu)設(shè)計以及二層臺等設(shè)備的改造。對外掛平臺、管柱移運裝置以及改造后二層臺利用有限元分析其靜態(tài)特性和管柱移運裝置的固有頻率,同時分析移運橫梁和移運小車在管柱移運裝置上行駛時,管柱移運裝置的靜態(tài)特性變化規(guī)律。防止因結(jié)構(gòu)不合理、材料強度不足以及共振現(xiàn)象導(dǎo)致裝置損壞。建立原井架梁單元模型和安裝管柱移運裝置后井架整體梁單元模型,得到井架及管柱移運裝置在相應(yīng)載荷下的變形和應(yīng)力分布云圖,提取相應(yīng)節(jié)點數(shù)據(jù),分析管柱移運裝置的安裝對井架的影響。
[Abstract]:As the consumption of oil and gas resources increases day by day, the discovery of conventional oil and gas fields is gradually decreasing and the exploitation of traditional oil and gas producing areas is becoming more difficult. Developing new oil and gas resources from the ocean has become a very important deployment. Therefore, it is very important to improve the configuration of offshore drilling equipment and improve drilling efficiency. At present, most offshore drilling platforms are equipped with top drive systems. To achieve vertical root drilling, thus reducing the time to connect and unload the drill pipe to improve drilling efficiency. However, due to the narrow space within the Derrick, It is difficult to equip with a corresponding drill pipe discharge device and a single connecting root device. Therefore, explore a solution that can increase the drilling space of the platform, It is very important to design the root-connecting device of drilling platform which has been installed with top drive. Based on the investigation of offshore platform structure, drilling machine and off-line single root connection, this paper combines the Derrick type of offshore drilling and repairing machine. An off-line single device for K Derrick is designed. According to the structure and distribution of drilling platform, a method of increasing the surface area of drilling table is put forward according to the structure and device distribution of the rig. On the basis of the feasibility analysis of installation of the external platform, The installation position selection, function analysis and scheme selection of external platform and off-line single root device are completed, and the process flow of off-line single root connection is designed, and the external storage platform is completed. The structural design of the pipe string moving device and the modification of the second floor equipment. The static characteristics and the natural frequency of the pipe string moving device are analyzed by using finite element method for the external platform, the pipe string moving device and the two-story platform after the transformation. At the same time, the change law of static characteristics of the pipe string moving device is analyzed when the moving beam and the moving car are travelling on the pipe string moving device, so as to prevent the unreasonable structure, The failure of material strength and resonance caused the damage of the device. The model of the original Derrick beam element and the integral beam model of the Derrick after the installation of the pipe string moving device were established, and the deformation and stress distribution of the Derrick and the pipe string moving device under the corresponding load were obtained. The influence of installation of pipe string moving device on Derrick is analyzed by extracting relevant node data.
