Particle jet flowing state is optimized by combining 40-degree and 13-degree dual-stage contracting sections and a phi 3mm straight cylinder section according to the previous hybrid particle jet nozzle wear mechanism studies and drilling hydromechanics knowledge, thus improving the particle acceleration capacity; 35CrMo material is selected to process the nozzle through quenching treatment; the wear-resisting capacity of the nozzle is improved and the service life of the nozzle is prolonged; moreover, basis is provided for developing particle impact drill hammer suitable for deep well and hard formation drilling.
Description
Technical field
The utility model relates to a kind of particle impacting drilling experiment nozzle, especially can improve the anti-wear performance of nozzle in the particle impacting drilling simulation experimentation, prolongs the nozzle particle impacting drilling experiment nozzle in service life.
Background technology
In recent years, along with the continuous exhaustion of China's Shallow Oil-Gas resource, under deep hard formation and complex geological condition, seek oil gas and find it is the important process of present land exploration and development.But there are difficult problems such as speed is slow, drilling period length, drilling cost height in deep-well and the ultradeep well hard formation drilling process at present, directly restricting the overall efficiency of deep-well and ultradeep well bit speed and exploration and development.Therefore, the new method of research efficient drilling well in the deep-well hard formation is imperative.
The particle impacting drilling technology is a kind of special efficient drilling technology at the deep hard formation that grew up in recent years, it is at the high-voltage tube place between slush pump and drill string spherical steel grit to be sneaked in the drilling fluid, drilling fluid carries particle and enters standpipe and be delivered to downhole drill bit, particle is with ejection at a high speed, impact grinding is broken rock, is that the high speed hydraulic drilling is that the broken rock of master, mechanical tooth is a kind of brand-new efficient well drilling and rock crushing method of assisting.It will break the rock mode and by traditional high-pressure water jet potential core the hydrostatic pressure of bottom rock be changed into erosion and the ablation of high-velocity particles stream to bottom rock, improved energy utilization ratio greatly, its bit speed is 2～4 times of conventional drilling, has broad application prospects and develops value.(ParticleDrilling Technology, Inc.) company proposes and develops this technology to the PDTI of the U.S. the earliest, has now entered the business exercise stage.The greatest difficulty that the particle impacting well system runs at present is that the particle impacting bit life is shorter, the lower and serious wear of nozzle performance.The researcher attempts to test by chamber particle impact cutting rock always and develops a kind of high-efficiency abrasion-proof nozzle, but does not make a breakthrough at present, and this just impels us to develop long particle impacting drilling experiment nozzle of a kind of high-efficiency abrasion-proof, life-span.
Summary of the invention
The deficiency that particle impacting drilling bit nozzle performance is low in order to overcome, the life-span is short, the utility model provides a kind of particle impacting drilling experiment nozzle, laboratory experiment confirms, this nozzle not only can improve the particle acceleration, and can effectively improve the nozzle wearability, prolong nozzle life, assurance particle impacting drillng operation is stable effectively to carry out.
The technical scheme that the invention for solving the technical problem adopted is: as Fig. 1, the particle impacting drilling experiment belongs to a kind of two-stage contracting noz(zle) with nozzle, form by nozzle one-level contraction section (a), nozzle secondary contraction section (b) and nozzle right cylinder section (c) three parts, 40 ° of one-level contraction section cone angles, length 10mm, 13 ° of secondary contraction section cone angles, length 7.81mm, right cylinder section diameter 3mm, length 9.19mm.Find by preceding stuff and other stuff jet nozzle Study on Wear Mechanism, two-stage contracting noz(zle) performance is better than the single-stage contracting noz(zle), the two-stage contracting noz(zle) wearability of 40 ° and 13 ° combinations is stronger, utilizes similarity principle and bit pressuredrop formula to calculate nozzle diameter and is 3mm.In the particle impacting drilling experiment process, nozzle is connected on the liquid jet instrument of confined pressure experiment frame inside, (diameter 0.2mm～0.8mm) enters high pressure line between plunger displacement pump and the confined pressure experiment frame by abrasive can to the steel particle, after drilling fluid fully mixes, arrive in the confined pressure simulation wellbore hole by high pressure line and liquid jet instrument, after in tube, passing through the acceleration of two-stage contracting noz(zle), speed can reach more than 95% of liquid velocity, (150m/s～250m/s) leaves behind the nozzle moment bump rock surface to high-velocity particles, when particle clashes into rock suddenly, can be at the stress wave of generation somewhere of rock, after this stress wave can be propagated to crash direction with certain speed, diffusion around rum point simultaneously makes rock on every side be subjected in various degree impact, can produce tension and shear stress around impacting the border, contact zone.Because the tensile strength of rock only is 1/80～1/16 of its compression strength, shearing strength only is 1/15～1/8 of a compression strength, when tension and shear stress have surpassed the ultimate strength of the tension of rock and shearing resistance respectively, in rock, will form crack, compression " awl ", dominance crackle and recessive micro-crack, produce broken landwaste simultaneously.
The beneficial effects of the utility model are, improve the service life of nozzle in the particle impacting well drilling and rock crushing experimentation effectively, for the exploitation of highly effective particle drill hammer in the deep-well hard formation provides technical support.
