摘 要
鉆探用泵是鉆探設(shè)備的重要組成部分之一。鉆探用泵主要是洗孔用泵，在我國地礦部的部頒標(biāo)準(zhǔn)定為泥漿泵，泵的形式定為往復(fù)式泵。在鉆探施工中，泥漿泵擔(dān)負(fù)著向孔內(nèi)輸送清洗液，并能使其在孔內(nèi)循環(huán)的作用。在某些特種工序中還用泥漿泵向孔內(nèi)灌注水泥漿等物質(zhì)。
泥漿泵是石油礦場鉆井作業(yè)中的關(guān)鍵設(shè)備之一，它的性能、結(jié)構(gòu)、可靠性、適應(yīng)性、經(jīng)濟(jì)性以及使用壽命，直接影響著鉆井質(zhì)量的好壞。泥漿泵是往復(fù)泵的一種。本人所設(shè)計(jì)的泥漿泵是臥式三缸單作用往復(fù)式活塞泵，它是通過活塞部件的往復(fù)運(yùn)動(dòng)，引起密閉的工作腔室容積變化，從而形成腔室內(nèi)外壓力差變化，以吸入和排出液流實(shí)現(xiàn)能量轉(zhuǎn)換的。該臥式三缸單作用泵在生產(chǎn)實(shí)踐中得到了廣泛的應(yīng)用。
關(guān)鍵詞： 泥漿泵 ，往復(fù)泵，鉆井
ABSTRACT
The drilling pump is one important part of drilling equipment. The drilling pumps are mainly used to wash hole, in our country geology and mining depart- ment proclaimed the standard decides as the mud pump, the form of the pumps designed as the reciprocating pump. In the drilling construction, the mud pump is used to transport the cleaning liquid to the hole, and make it at the hole continual recycling. Also using the mud pump in certain special working procedures to pour matter and cement mortar to the hole.
A mud pump is one of the critical equipments for petroleum drilling operations, the performance, structure, reliability, suitability, cost and service life of a mud pump will directly affect the drilling operations. The mud pump is a kind of the reciprocating pump. The pump designed myself is three plunger reciprocating pump, it is through the piston part reciprocal motion, causes the airtight work cavity room volume change, thus forms the pressure of the cavity room in side and outside different, and discharges the energy by the inspiration. The successful development of the pump produces a good profit for our factory, and plays an important active role in oil field development and full use of the resources.
