Description
Technical field
The present invention relates to a kind of drilling pump and boosting method thereof that is provided with T-shaped pump head.
Background technique
The application of reciprocating pump in petroleum industry is very extensive, often need the under high pressure liquid of transfer of highly viscous, large proportion and high sediment concentration on oilfield, and flow is relatively little, shows from the work characteristics contrast of various pumps, and reciprocating pump relatively is applicable to this situation.Reciprocating pump is used as circulating mud and injects cementing concrete when drilling well.When recovering the oil, as Crude Oil Transportation, well-flushing, water filling and formation breakdown.Deep-well pump in pumping unit is also a kind of reciprocating pump of special construction.So, reciprocating pump be oil general with one of equipment key.
According to the difference of pump structure features and action, can be divided into the three basic type.(1) positive displacement pump: rely on to contain the variation of the seal operation space periodicity of liquid, energy cycle pass to liquid, the pressure of liquid is increased to liquid is discharged by force.(2) impeller pump: rely on the impeller of rotation to the dynamic action of liquid, energy is passed to liquid continuously, the speed energy of liquid and the energy of pressure energy are increased, by delivery chamber, most of speed can be converted to pressure energy subsequently.(3) other types pump.
Along with the increase of the drilling degree of depth, require more and more higher to rig and the miscellaneous equipment that matches with it.At present both at home and abroad the drilling pump structure can be divided into three kinds by the position of high pressure suction valve and expulsion valve: the one, and suction valve and expulsion valve all are arranged in clack box, and two valves are on same axis, and be vertical with the axis of cylinder sleeve.This type of clack box is on the I type.Two is that a valve is arranged in clack box, and a valve is arranged on outside clack box, and two valves are vertical with the axis of cylinder sleeve.This type of clack box is L-type.The 3rd, suction valve is mutually vertical with the axis of expulsion valve mounting point, and suction valve and cylinder sleeve be on same axis, consists of T font liquid chunnel.
Utilize the drilling pump drilling well history of existing more than 100 year.Drilling pump is updated development in these more than 100 years.The dark oil well that commercial value is arranged of the 336m that the developing history of drilling pump gets out take the Spindletop of Texas, USA in 1901 is as starting point.This is also the starting point of Oil/gas Well rotary drilling in modern age history.At that time, the drilling pump that drilling well is used was double cylinder double acting piston steam pump, and pump pressure is 17.3 * 105Pa.This pump is not specially for slurry pump designs, but general raw water service pump.
The steam pump of producing in 1917 has been custom-designed drilling pump.The pump head of this pump is namely the embryo of double cylinder double acting drilling pump fluid end today.The point of its main difference is pump valve or flap type at that time.This pump uses the thirties always.
The steam that the power of steam pump produces from boiler.But at mining site, the using and transport all inconvenient of boiler.Therefore, the steam drilling pump is replaced by oil-engine driven motor pump gradually.Maximum double cylinder double acting motor pump is to produce nineteen twenty-six in nineteen thirties.Its piston diameter is 170mm, and stroke is 457mm, and power is 110-147Kw, and Maeximum pump pressure can reach (100-125) * 105Pa.The design of this pump and present duplex double action pump are quite approaching.Its fluid end has used mitre velve, and reduction gear, eccentric shaft, connecting rod and the crosshead of helical teeth arranged in driving end, has adopted airtight splash lubrication, and the fluid end discharge tube is equipped with the air bag.But connecting rod tip is also used sliding bearing.
To the mid-1930s, because the load of pump is increasing, drilling pump has just adopted full bearing design.But there is no at that time large diameter rolling bearing, so main shaft adopts cantilever type crank shaft scheme more, the rolling bearing inner ring of connecting rod tip fixes on crank cotter pin.
Along with the increase of drilling well well depth and increasing of casing program, more and more high requirement has been proposed for drilling well pump delivery and pump pressure.After World War II, mud property improves to some extent, and has carried out simultaneously the research and development work of jet drilling technology.At this moment drilling operator's major requirement improves pump pressure.From the end of the forties to the mid-50, the research and practice of jet drilling has proposed the pump pressure requirement of 150-210 * 105Pa.The end of the forties drilling pump power, reached 600Kw.Simultaneously, most of company rolls back 457mm (18in) to the maximum stroke length of pump.
The fifties, twin cylinder pump was along with the sharply increasing of pump power, and the weight of pump and boundary dimension also increase thereupon.Heavy for alleviating pump, larger improvement was for iron with to reduce pump wide with steel in the design of twin cylinder pump at that time.Be the pump case of using Plate Welding with steel for iron, and use some parts instead the high duty alloy manufacturing; Reducing pump wide is to use the large diameter axis of rolling to make the connecting rod tip supporting, the scheme of the cantilever crank shaft of giving up and adopt the eccentric shaft design of two ends freely-supported.Like this, two cylinder centre distance are obviously dwindled.
The beginning of the sixties, be badly in need of a kind of pump pressure of Design and manufacture and can adapt to the jet drilling technological requirement, volume is little, lightweight simultaneously, can satisfy the drilling pump of the installation and transportation condition of ocean, desert drill at that time.Each company has all done a large amount of research work.What wherein target was relatively concentrated is to be modified as drilling pump for the three-cylinder plunger pump of well cementation pressure break, because it just in time can satisfy above-mentioned requirements.In the incipient stage of development, problem still occur in mechanical energy be converted to fluid pressure can on interface---the life-span of plunger and plunger seal is too low in mud medium.The design of at this moment, one group " single action piston-uncovered cylinder sleeve-spraying water " has play a part crucial.It makes New Times of drilling pump history representing---the birth of three cylinder single-acting piston type drilling pumps.Compare with duplex double action pump, triplex single action pump has that volume is little, lightweight, efficient is high, flow is even, pressure surge is little and dismounting is easy to maintenance; Due to triplex single action pump, crank is mutually 120 °, and power end is stressed evenly.Coefficient of discharge is 0.141, and less than twin-tub and four cylinder single-acting pumps, discharge capacity is even, and advantages of simple structure and simple is arranged.Demonstrating good economic benefit in using widely, at home and abroad deep-well replaces duplex double action pump in creeping into gradually.
Through the development of the decades thirties to the eighties, the drilling pump of domestic production be all horizontal three cylinder single-action reciprocating reciprocating pumps abroad, basic parameter and structure are close with American National Instrument Oilwell company.The product line of pump is 500HP, 800HP, 1000HP, 1300HP, 1600HP, 2000HP, and wherein the 1600HP drilling pump is prominent a kind of pump type in present domestic drilling pump.Main manufacturer has blue stone national oil well rig Co., Ltd (hereinafter to be referred as " Lan Shi "), Baoji Petroleum Machinery Co., Ltd.'s (hereinafter to be referred as " jewel "), petrolem machinery factory, Yidu etc.Overall technology level and the American National Instrument Oilwell company of domestic blue stone and jewel production nineties drilling pump are very approaching, but powerful 2200HP drilling pump is still blank at present at home.All there are pluses and minuses separately in domestic pump at aspects such as structure and technical parameter, workmanships.Wherein, the advantage of the F series pump that jewel factory produces is that structure and technical parameter are more advanced rationally, and close with U.S. Emsco company, manufacturing process is advanced, and quality is better.The advantage of blue stone pump is that the hydraulic end sealed reliability is higher, and the life-span is longer, and using effect is better in the oil field; Shortcoming is that the power end structure is complicated.The research of the early 21st century China drilling pump makes great progress, and has now developed the F-2200HL drilling pump, and product is found a good sale in the states such as Canada.Still there are the low problems of easily damaged parts life-span such as drilling pump valve body, piston at present in China generally, also needs to add the great development dynamics for the hydraulic drill well pump.
The layout of existing pump head has three kinds usually, and I type straight-through type arrangement is conducive to the suction of fluid cylinder.But for the high speed triplex pump, suction is full of problem, and is more outstanding, and is inconvenient to keep in repair.The L-type arrangement can make liquid flowing ratio more steady, reduces vibration and pressure surge.And suction valve can be dismantled separately, is convenient to maintenance.T-shaped arrangement, structural advantages is as follows: (1) pump head structure is compact, has cancelled suction chamber, and its volume and quality all reduce 25%-30%; (2) be easy to manufacturing, be convenient to flaw detection and check, can guarantee the quality of pump head product; (3) level sucks mud, and pump head fluid cylinder inside clearance volume is less, has improved suction efficiency and the volumetric efficiency of drilling pump; (4) the liquid levelling is steady, has reduced fluctuation and the vibration of pressure, reduces the drilling pump impulsive load; (5) the replacing suction valve is very convenient, saves time, and the workload of disassembling, assembling and replacing is less.
