摘要
本課題研究內(nèi)容屬于修井井口作業(yè)自動化系統(tǒng)中動力卡瓦的結(jié)構(gòu)設(shè)計。課題主要目的就是用動力卡瓦實現(xiàn)對管柱的提升,卡緊及懸掛。設(shè)計中,利用液壓缸施加作用力,經(jīng)連桿機構(gòu)的傳遞,推動卡瓦楔體沿卡瓦座體內(nèi)錐面上下運動,上行時,卡瓦牙板內(nèi)徑不斷增大,使管柱通過;下行時,卡瓦牙板收攏,內(nèi)徑變小,從而卡緊管柱。
對于管柱的卡緊與懸掛,在井口作業(yè)中是一個重要的組成部分。動力卡瓦是卡住并懸掛下井的油管、鉆桿、鉆鋌等管柱的必要工具,但是每一種結(jié)構(gòu)的卡瓦都有它的優(yōu)點和缺點。本課題主要是對動力卡瓦進行結(jié)構(gòu)設(shè)計以及對動力卡瓦承載零件的受力分析和強度校核。
關(guān)鍵詞:卡瓦;結(jié)構(gòu);強度;懸掛能力
Abstract
The content of this research are workover operations wellhead automation system dynamics of the structural design of Slips. The main purpose of the subject is to use power to achieve string slips upgrading cards and hanging tight. Design, use of force to exert hydraulic cylinder, the transmission linkage, and promote slips kava wedge blocks along the upper and lower body movement cone, on the line, slips increasing diameter of dental lamina, so that through the string; downlink, the slips drawing in dental lamina, smaller diameter, thereby card string tight.
For the string tight and the suspension of the card, operating in well-head is an important component. Driving force for slips is jammed and flying to go down the pipeline, drill pipe, drill collar, such as an essential tool string, but the structure of each slip has its own advantages and disadvantages. The main issue is the driving force for the structural design of Slips and Slips bearing parts of the power and strength check of force analysis.
Key words: slips; Structure; Strength; Hoisting capacity
