【摘要】：隨著石油鉆井技術(shù)的不斷發(fā)展,鉆井井深不斷加大,常規(guī)旋轉(zhuǎn)鉆井速度慢、效率低成為了制約鉆井技術(shù)發(fā)展的因素之一,而超高壓水射流輔助鉆井技術(shù)可顯著提高鉆井速度。目前國內(nèi)已研制出各種不同原理的井下增壓器,但現(xiàn)有增壓器還存在不足,主要是結(jié)構(gòu)比較復(fù)雜、不易加工、使用壽命短。因此,為了提高鉆井速度,設(shè)計(jì)了一種新的螺桿換向式井下增壓器。螺桿換向式井下增壓器通過使用螺桿馬達(dá)帶動轉(zhuǎn)動閥轉(zhuǎn)動,通過轉(zhuǎn)動閥開啟關(guān)閉與彈簧壓縮復(fù)位配合,使柱塞作直線往復(fù)運(yùn)動,產(chǎn)生高壓脈動射流。本文首先確定了增壓器的整體方案,并建立了增壓器的三維模型,詳細(xì)設(shè)計(jì)了上閥盤和組合運(yùn)動件等零件,對重要零件進(jìn)行了校核;然后,對柱塞缸內(nèi)關(guān)鍵零件進(jìn)行了詳細(xì)設(shè)計(jì)和校核,設(shè)計(jì)了柱塞高壓密封結(jié)構(gòu)和材料,計(jì)算了柱塞密封泄露量和單向閥的泄露量,根據(jù)設(shè)計(jì)壓力和流量確定了超高壓噴嘴的直徑;最后,根據(jù)設(shè)計(jì)參數(shù)對增壓器液壓系統(tǒng)進(jìn)行了建模仿真,仿真結(jié)果與計(jì)算結(jié)果相符。經(jīng)過對增壓器的詳細(xì)設(shè)計(jì)和建模仿真,驗(yàn)證了方案的可行性。螺桿換向式增壓器的設(shè)計(jì)完成,也必定會為今后提高鉆井速度的研究起到非常重要的指導(dǎo)意義。
[Abstract]:With the continuous development of petroleum drilling technology, the drilling depth is increasing, the conventional rotary drilling speed is slow and the low efficiency has become one of the factors restricting the development of drilling technology, while the ultra-high pressure water jet assisted drilling technology can significantly improve the drilling speed. At present, a variety of downhole turbochargers of different principles have been developed in our country, but the existing superchargers still have some shortcomings, such as complicated structure, difficult to process and short service life. Therefore, in order to improve drilling speed, a new screw commutative downhole supercharger is designed. The screw commutative downhole supercharger uses the screw motor to drive the rotation of the rotary valve, and through the opening and closing of the rotary valve to cooperate with the spring compression reset, the plunger moves in a straight line and produces a high pressure pulsating jet. In this paper, the whole scheme of the supercharger is first determined, and the three-dimensional model of the supercharger is established, and the parts such as the upper valve disc and the combined moving parts are designed in detail, and the important parts are checked. The key parts in the plunger cylinder are designed and checked in detail, the structure and material of the plunger high pressure seal are designed, the leakage quantity of the plunger seal and the leakage quantity of the one-way valve are calculated, and the diameter of the ultra-high pressure nozzle is determined according to the design pressure and flow rate. Finally, the hydraulic system of the supercharger is modeled and simulated according to the design parameters, and the simulation results are in agreement with the calculated results. The feasibility of the scheme is verified by the detailed design and modeling simulation of the supercharger. The design of screw commutator supercharger will certainly play a very important guiding role in the research of improving drilling speed in the future.
