【摘要】：水平井、定向井鉆井技術(shù)通過幾十年的發(fā)展已經(jīng)不斷成熟,隨著井深的增加,水平井深井鉆井技術(shù)已經(jīng)成為一個(gè)國(guó)家鉆井技術(shù)水平高低的標(biāo)志。井深的增加導(dǎo)致所鉆遇地層的硬度變大,常規(guī)的鉆井技術(shù)難以提高機(jī)械鉆速,唯有改變鉆井方式才是行之有效的方法。本文深入調(diào)研了國(guó)內(nèi)外鉆井提速的現(xiàn)狀,對(duì)現(xiàn)有的鉆井提速技術(shù)和提速工具的優(yōu)缺點(diǎn)和適應(yīng)性進(jìn)行了詳細(xì)的分析,在此基礎(chǔ)上,分析了影響水平井鉆速的因素并研究減摩降阻機(jī)理,最終確定了通過減摩降阻技術(shù)來提高水平井的機(jī)械鉆速,并以此為理論依據(jù)研制軸向振動(dòng)工具。詳細(xì)闡述了軸向振動(dòng)工具的結(jié)構(gòu)和各部件的研制,通過室內(nèi)試驗(yàn)、地面試驗(yàn)和現(xiàn)場(chǎng)試驗(yàn),驗(yàn)證了該工具的作用機(jī)理的正確性。認(rèn)為該工具主要應(yīng)用于水平井鉆井,能夠減小井下的摩阻和扭矩,減小粘卡的發(fā)生,提高機(jī)械鉆速。
[Abstract]:Horizontal well, directional well drilling technology through decades of development has been mature, with the increase of well depth. Deep well drilling technology in horizontal wells has become a symbol of the level of drilling technology in a country. With the increase of drilling depth, the hardness of the formation drilled becomes larger, and the conventional drilling technology is difficult to improve the drilling speed. Only by changing the drilling method is the effective method. This paper deeply investigates the current situation of drilling speed raising at home and abroad, and analyzes the advantages, disadvantages and adaptability of the existing drilling speed raising technology and tools in detail. On this basis, the factors that affect the drilling speed of horizontal wells are analyzed and the mechanism of reducing friction and drag is studied. Finally, the mechanical drilling speed of horizontal wells is improved by reducing friction and reducing resistance. The structure of the axial vibration tool and the development of each component are described in detail, through indoor test, ground test and field test. It is considered that the tool is mainly used in horizontal well drilling, which can reduce the friction and torque, reduce the occurrence of sticking cards, and improve the drilling speed.
