【摘要】：目前,國內(nèi)現(xiàn)有鉆機與國外同類型鉆機相比,普遍存在移運不方便、搬遷安裝時間長、拆裝工作量大和運輸車次多等問題,鉆井效率低,已經(jīng)不能滿足市場的要求,特別是鉆深為4000m、5000m的中深井鉆機。為此,開發(fā)出一套既能適合油田中深井開采,又能節(jié)約鉆井成本、縮短鉆井周期的模塊化鉆機,已成為市場迫切的需要。本文主要設(shè)計了一種ZJ50DB模塊化鉆機井架,首先根據(jù)模塊化鉆機的特點確定了鉆機的總體方案,重點針對井架的設(shè)計思路和結(jié)構(gòu)形式進(jìn)行了說明;其次,對井架的總體尺寸、各段結(jié)構(gòu)形式和連接方式,井架的起升方式及其附件進(jìn)行了設(shè)計,井架背橫梁采用了能夠翻轉(zhuǎn)的折疊形式,段與段之間采用了新型的快速連接方式,井架和底座采用一副液缸梁起升,并利用Autodesk Inventor軟件建立了井架的三維造型,生成了工程圖;最后利用SAFI軟件建立了井架有限元模型,對其靜強度和模態(tài)進(jìn)行了分析,同時利用ANSYS軟件對井架支座、段連接耳板和起升液缸梁進(jìn)行了強度校核計算,所設(shè)計井架結(jié)構(gòu)合理,安全可靠。
[Abstract]:At present, compared with the same type of drilling rigs abroad, the existing domestic drilling rigs generally have the problems of inconvenient transportation, long relocation and installation time, large workload of disassembly and assembly and many times of transport vehicles, etc., and the drilling efficiency is low. It has been unable to meet the requirements of the market, especially the medium-deep drilling rig with a depth of 4000mm-5000m. For this reason, a set of drilling rig can be developed which can not only be suitable for the production of medium-deep wells in oil fields, but also save the drilling cost. The modular drilling rig which shortens the drilling cycle has become an urgent need of the market. This paper mainly designed a ZJ50DB modular drilling rig Derrick, first according to the characteristics of the modular drilling rig to determine the overall scheme of drilling rig. The design idea and structure form of Derrick are explained in detail. Secondly, the overall size of the Derrick, the structural form of each section and the connection mode, the hoisting mode of the Derrick and its accessories are designed. The back beam of the Derrick adopts the folding form that can be turned over. A new type of quick connection method was adopted between the sections. The Derrick and the base were lifted up by a pair of liquid cylinder beams, and the 3D modeling of the Derrick was established by using Autodesk Inventor software. The engineering drawing is generated; Finally, the finite element model of Derrick is established by using SAFI software, and its static strength and mode are analyzed. At the same time, the Derrick support is analyzed by ANSYS software. The strength of the connecting ear plate and the lifting cylinder beam is calculated and the structure of the Derrick is reasonable and safe and reliable.
