Description

煤矿井下钻孔的钻进、增透、修复与气驱置换综合方法 Coal mine drilling drilling, AR, repair and replacement of gas drive integrated approach

技术领域 FIELD

[0001] 本发明属于煤层气开采技术领域,特别涉及一种煤矿井下钻孔的钻进、增透、修复与气驱置换综合方法。 [0001] The present invention belongs to the technical field of coalbed methane extraction, more particularly to a coal mine borehole drilling, AR, repair and replacement synthesis gas flooding method.

背景技术 Background technique

[0002] 我国煤矿瓦斯灾害严重,严重制约着煤炭企业的安全生产。 [0002] China's coal mine gas disaster seriously, seriously restricting the safe production of coal enterprises. 瓦斯抽采是我国目前进行瓦斯治理的主要技术手段,但由于我国煤层松软、赋存复杂,钻进过程中存在卡钻、顶钻、掉钻、钻杆连接困难,排渣不及时难以拔钻等现象,制约着煤层钻孔钻进速度和质量;煤层透气性系数对瓦斯抽采效果起着决定性作用,而我国的大部分高瓦斯突出矿井都属于低透性煤层,决定了我国大部分矿井抽采困难,单孔抽采量低下、有效抽采时间短。 Gas drainage is the primary means of ongoing technical gas control, but because of soft coal, occurrence of complex, there is sticking drilling process, the top drilling, out drilling, drill pipe connection difficulties, not slagging promptly difficult corkscrew and other phenomena, which restricts the coal seam drilling drilling speed and quality; seam permeability coefficient of gas drainage effect plays a decisive role, while China's most high gas outburst are low permeability coal seam, determines most of our mine drainage difficulties, low extraction hole recoverable amount, effective drainage time is short. 另外,随着时间的推移,瓦斯抽采钻孔也存在塌孔、积水、增加瓦斯启动压力梯度的可能性,严重影响了煤层钻孔瓦斯抽采的质和量,使瓦斯抽采消突难以按期达标,甚至没有达标钻孔便已坍塌,只能以补打钻孔作为补充措施。 Further, over time, there is gas drainage drilling hole collapse, water, gas pressure gradient increases the likelihood of a serious impact on the quality and quantity of drilling drainage gas coal, so that gas drainage dissipation protrusion difficult schedule compliance, even standard no drilling had already collapsed, only to fill drilling as a supplementary measure to fight.

[0003] 针对以上情况,我国目前已有不少的大功率钻机相继研发并投入到生产应用中,但依然没有实现钻杆连续钻进,钻孔及时排渣等功能。 [0003] For the above, there are a lot of high-power drilling rigs have been developed and put into production applications, but still did not achieve continuous drilling drill pipe, drilling timely slag and other functions.

[0004] 我国煤层瓦斯治理关键在于煤层的增透,目前煤层增透主要以水力化措施为主,如水力压裂、水力冲孔、水力挤出、高压注水等,另外还有松动爆破、空气置换等,尽管取得了一定的成绩,但由于受技术应用的复杂性(裂缝开启不均匀、应力集中混乱等)及设备的难以操控性(设备体积庞大、操作复杂)等因素的影响,都没有大规模的推广应用。 [0004] of coal seam gas control key is AR coal, coal at present mainly in AR water-based measures, such as hydraulic fracturing, hydraulic punching, hydraulic extrusion, high pressure water injection, in addition to loose blasting air Effect of substitutions and the like, in spite of some achievements, but due to the complexity of the application of the technology is difficult to control (non-uniform open fracture, stress concentration confusion) and equipment (apparatus bulky, complicated operation) and other factors, are not large-scale application.

[0005] 由于受上覆岩层压力、采动应力、瓦斯压力、煤岩层裂隙水及煤体结构、强度等因素的影响,随着时间的推移,抽采钻孔会在不同程度上出现垮塌、积水等问题,导致抽采效率低下甚至作废,严重影响了矿井的消突计划及生产部署。 [0005] Due to the overburden pressure, mining pressure, gas pressure factors, coal-water and coal formation fracture structure, strength, etc., over time, will collapse the drilling drainage in varying degrees, water and other issues, resulting in poor drainage efficiency even set aside, seriously affecting the sudden elimination of the mine plan and production deployment. 为解决长时间抽采后钻孔塌孔、积水的问题,目前主要是靠在钻孔中压入高压风(矿井压风管供风,风压< 0.7MPa)进行排渣、透孔,针对孔长小于15m、倾角小于10°的俯角钻孔能够取得一定的效果,由于水压、风压压力值有限,对大孔长和大倾角钻孔却起不到排渣、透孔的目的。 In order to solve the long drainage bore hole collapse, water problems, the key is pressed against the borehole pressure air (supply air duct mine air pressure, air pressure <0.7MPa) for slag, the through hole, for the hole length is less than 15m, an inclination less than 10 ° depression angle of the borehole can be achieved certain results, water pressure, air pressure value of the pressure is limited, and large high inclined bore hole length slag was not achieve the purpose of through holes . 同时,也没有具有一定强度工具能够连续钻入已坍塌钻孔之内,因此,透孔效率低下,往往重新施工钻孔以作弥补。 There is also no tools having a certain intensity within a continuous drill the borehole has collapsed, and therefore, the through hole is low efficiency, often re-drilled to remedying the construction.

[0089] C、钻孔修复 [0089] C, drill repair

[0090] 对于已有的坍塌、积水钻孔,可利用矿用水力作业机压力大、排量大、连续性强的特点,使用高压水对钻孔进行清洗,使孔内坍塌煤渣排出孔外,除此之外,矿用水力作业机还可以在高压大流量水的作用之下,对钻孔进行割缝、扩孔,最大程度上达到透孔增透的目的,清洗钻孔后的水会残存在孔内,影响了瓦斯的抽采,此时,采用矿用压风将钻孔内残余水吹排出孔外。 [0090] For existing collapse, water drilling, mining can use water pressure force working machine, large displacement, strong continuity characteristics, the use of high-pressure water cleaning drilling the hole collapse slag discharge hole after the outside, in addition, mineral water power working machine may also be under the influence of high pressure and large flow of water, for slotted borehole, reaming, the purpose of antireflection of the through hole on the maximum extent, cleaning drilling water may remain in the hole, the influence of gas extraction, in which case, the use of air pressure within the mine borehole outer blow residual water discharge hole.

[0097] d、气驱增透 [0097] d, AR gas flooding

[0098] CH4 (瓦斯)和CO2与煤分子之间作用力的差异,导致煤对CH4和CO2吸附能力有所不同。 [0098] CH4 (methane) difference in force between molecules and CO2 and coal, for coal led to CH4 and CO2 adsorption capacity is different. 这种作用力与相同压力下CH4和CO2的沸点有关,沸点越高,被吸附的能力越强,CH4和CO2的沸点分别为-161°C和-78 °C,从而CO2在煤表面具有较强的吸附能力。 CH4 this action and the same pressure and having a boiling point of CO2, the higher the boiling point, the ability to be adsorbed, CH4 and CO2 are boiling point -161 ° C and -78 ° C, and thus has a more CO2 in the coal surface strong adsorption capacity. 同时,煤体对CH4和CO2的吸附试验已经证明了:煤对CO2的吸附能力大于煤CH4吸附能力。 Meanwhile, the assay coal for CH4 and CO2 have demonstrated: Coal CO2 adsorption capacity of greater than coal CH4 adsorption capacity. 这些研究都充分论证了在煤表面CO2具有很强的驱CH4能力,为CO2置换驱替CH4的实施提供了理论基础。 These studies have fully demonstrated a strong ability to drive CH4 CO2 coal surface, the replacement for the CO2 flooding provides a theoretical basis for the implementation of CH4.

[0099] I)选择瓦斯抽采效果差的钻孔作为实施孔,且排除塌孔或积水造成的抽采效果差的钻孔,打开抽采管,将矿用水力作业机的挠性钢管通过输管器下放至钻孔孔底,并对钻孔孔口用长度不小于Im的充气橡胶圈进行密封,将清水泵站内的介质换为气体,向挠性钢管内注气; [0099] I) poor choice of gas drainage drilling a hole embodiment, and excluding poor drainage bore holes or collapse caused by water, open the drainage pipe, the water force of the flexible steel mine working machine downpipe is lowered through the borehole to the hole bottom, the aperture and the bore is not less than the length of Im inflatable rubber seal ring, the water pump station exchange medium within the gas, gas injection into the flexible steel tube;

[0100] 2)计量实施孔周边钻孔的瓦斯抽采量,观测其在注气前、中、后的瓦斯抽采流量和浓度的变化情况; Gas [0100] 2) surrounding the bore hole embodiment of the metering extraction volume, which is observed before gas injection, the gas, after the extraction of changes in flow rate and concentration;

[0101] 3)开启清水泵站,高压气通过挠性钢管被送至孔底,由于孔口密封,钻孔内压力值不断上升,当孔内注入压力高于预计注入压力时,增大挠性钢管内的注入气量,注入压力增大,当注入压力增大至设计压力120%时,保持恒定注入气量; [0101] 3) water pumping station open, high pressure gas is supplied through a flexible steel bottom of the hole, as the aperture is sealed, pressure rise within the bore, the bore when the injection pressure is higher than expected injection pressure, increased scratch injection of gas within the steel tube, the injection pressure is increased, when the injection pressure is increased to 120% of design pressure, gas injection is kept constant;

[0102] 4)煤体中的瓦斯在注入高压气的驱动置换下,向实施孔的周边钻孔流动,以提高该区域瓦斯抽采效果; Gas [0102] 4) coal is injected at high pressure driving gas replacement, the flow of drilling holes to the periphery of the embodiment, in order to increase the effect of extraction of gas in the region;

[0103] 5)测量统计实施孔的周边钻孔的抽采流量变化情况,抽采流量与浓度增大的抽采钻孔中,与实施孔距离最远的间距为该注入气量下的气驱半径。 [0103] 5) measurement statistics embodiment drainage holes flow change situations surrounding the borehole, drainage flow and an increased concentration in the drainage bore, the pitch for the embodiment farthest hole injecting gas under gas flooding radius.

[0104] 除了使用CO2进行气驱增透之外,还可以使用空气进行气驱,但由于气驱过程中需要封堵钻孔口,并且在注气过程中,由于钻孔阻力作用,注入的空气或CO2难以以较高压力到达孔底,从容影响了气驱效果。 [0104] In addition to using CO2 gas drive for AR, but also air may be used for gas injection, but the gas flooding process requires blocking bore opening, and gas injection process, due to the drilling action of the resistance, the injected air or CO2 difficult at higher pressure reaches the hole bottom, calm affect the gas drive. 使用水力喷射装备,可以通过连续油管将气体注入到孔内的任何位置,并且对于长钻孔,也可以直接在其孔底进行气驱而不需要进行封孔。 Using water jet equipment, coiled tubing by injecting gas into the bore at any position, and for long drilling, gas injection may be performed directly thereon without the need for plugging the hole bottom.

[0105] 在本发明中,高压水射流是以水为工作介质,具有极高的能级密度,在煤层钻孔方面,高压水射流钻孔具有以下几方面的优点:高压水射流钻进时,通过水射流切割煤岩,喷嘴与煤体没有直接接触,不会出现机械钻头的发热、磨损、寿命短等缺陷,且成孔直径大、钻进速度快、能耗低,可有效避免机械钻孔时出现的卡钻、夹钻等现象,同时可以提高钻孔周围煤层的透气性;高压水射流钻进时,孔底处于淹没状态,温度低,没有火花产生,可用于具有自燃煤层中的钻孔;在连续挠性钢管作用下,可实现煤、岩层钻孔的连续钻进,不需要换接钻杆,使钻孔施工简便易行。 [0105] In the present invention, high pressure water jet is water as the working medium, with a high level of density, in terms of seam drilling, water jet drilling has the following advantages: the high pressure water jet drilling time , coal, coal nozzle and cut by a water jet is not in direct contact, heat will not be a mechanical drill bit wear, defects such as short life and large pore diameter, fast drilling speed, low energy consumption, which can effectively avoid mechanical card appears drilling drill, drilling phenomena clip, while improving permeability of the coal seam surrounding a borehole; high-pressure water jet drilling, a bottom hole is submerged, the temperature is low, no sparks can be used for seam pyrophoric drilling; action in the continuous flexible steel, coal can be achieved, continuous drilling rock drilling, for access do not need to drill the borehole simple construction.

[0106] 煤层增透是对煤层进行水力喷射压裂,达到定点、定向、均匀压裂的目的,主要可实现水力冲洗卸压、水力喷射压裂和水力吞吐压裂等工艺。 [0106] Antireflection seam coal seam is hydraulic fracturing jet, to point, orientation, uniform fracturing purpose, the main relief water washing can be realized, and hydraulic fracture stimulation hydraulic jet fracturing process.

[0107] 吞吐式水力冲洗卸压过程是煤体破坏剥落排出,应力状态改变,瓦斯大量释放的过程。 [0107] Throughput of formula hydraulic pressure relief coal washing process is discharged disrupting peeling stress state change, a large amount of gas released in the process. 首先利用高压水射流破碎煤体,在一定时间内由本孔冲出大量煤体,形成较大直径的孔洞,从而破坏煤体原应力平衡状态,孔洞周围煤体向孔洞方向发生大幅度位移,促使应力状态重新分布,集中应力带外移,有效应力降低;其次煤层中新裂缝的产生和应力的降低打破了瓦斯吸附与解吸的动态平衡,使部分吸附瓦斯转化成游离瓦斯,而游离瓦斯则通过裂隙运移得以排放,大幅度地释放了煤体及围岩中的弹性潜能和瓦斯膨胀能,煤层瓦斯透气性显著提高;最后,高压水润湿了煤体,降低煤体中残存瓦斯的解吸速率。 First, using a high pressure water jet breaking coal, in a given time out of a large amount of coal by the hole, the larger diameter hole is formed, thereby destroying the original coal stress equilibrium state, the holes around the coal occurs greatly displaced holes direction, prompting redistribution of stress state, with the relocation of stress concentration, reduce the effective stress; followed by the coal seam and reduce the stress generated new crack to break the homeostasis of gas adsorption and desorption of the adsorbed gas is converted into the free part of the gas, while the free gas through fracture migration is discharged, the potential of greatly released and the elastic expansion of gas in the surrounding rock and coal energy, coal seam gas permeability significantly improved; Finally, a high-pressure water wetted coal, coal to reduce the desorption of residual gas in the rate. 水力冲洗过程冲出了大量瓦斯和一定数量的煤,因此在煤体中形成一定的卸压、排放瓦斯区域,在这个安全区域内,破坏了突出发生的基础条件,起到了有效的防治突出效果。 Water washing process out of a lot of gas and a number of coal, and therefore a certain relief, methane emissions in the coal region, the security in this region, undermining the basic conditions outburst, played a prominent and effective prevention and treatment effect .

[0108] 对已施工完成钻孔,选择合适的水力喷射喷头喷嘴,开动水力喷射装备,不加入高压水,当连续油管伸入到孔底时,通过高压水泵向水力喷射器加入高压水,高压水经过连续油管,最后又喷嘴喷出,钻孔在喷嘴喷出的高压水作用之下,使附着在孔壁的煤、岩粉排除孔外。 [0108] The construction has been completed bore, select the appropriate hydraulic jet head nozzle, actuating the water jet equipment, without the addition of high pressure water, when the coiled tubing extending into the hole bottom, water was added to the high-pressure water jet through the high pressure pump and a high pressure water through coiled tubing, nozzles and finally, the drilling action of water under high pressure nozzle, so that the cell walls adhered to coal, rock dust exclusion outer aperture. 同时,由于高压水的射流冲蚀,使钻孔孔径扩大,局部形成空腔,加大了钻孔卸压空间,增大了煤层透气性系数,提高了抽采效率。 Meanwhile, since the high-pressure water jet erosion, so that the drilling diameter expansion, locally forming a cavity, increasing the drilling pressure relief space, increasing the permeability coefficient seam, improving the extraction efficiency.

[0109] 对未施工钻孔,可使用水射流装备钻进,钻进完成实施冲洗卸压,同已施工完成钻孔。 [0109] The construction of non-drilling, water jet drilling equipment, drilling flushing complete relief, the construction has been completed with the borehole.

[0110] 水力喷射压裂应用于井下硬煤主要有喷射和压裂两个作用。 [0110] Hydraulic fracturing is applied to the downhole injection of hard coal and fracturing two main injection effect. 由压裂泵增压后的流体,经毫米级直径的喷嘴后转化为高速射流,并迅速进入煤层。 After the fracturing fluid by a booster pump, after millimeter diameter nozzle into a high velocity jet, and quickly into the coal seam. 由于钻孔孔口体积有限及水的不可压缩性,钻孔内流体会挤压射流,致使其轴心速度迅速衰减,巨大动能转化为内能,并在孔内衰减,高压水的巨大动能又重新转化为压能,使得孔内滞止压力迅速升高,形成增压效应。 Due to the limited size and the orifice bore incompressibility of water, the drilling fluid will jet extrusion, resulting in the rapid decay of the axial velocity, great kinetic energy into internal energy, and the attenuation in the hole, and the great kinetic energy of high pressure water converted back to pressure energy, so that the hole stagnation pressure increased rapidly formed pressor effect. 当孔内增压值超过地层起裂压力时,钻孔末端煤层就会立即起裂。 When the hole boost pressure exceeds the formation fracture initiation, drilling will immediately end seam initiation. 由于喷嘴周围会形成低压区,所以环空流体会被卷吸进入裂缝。 Since the formation of low pressure region around the nozzle, the annulus fluid will be entrained into the cracks. 驱使裂缝向前延伸。 Extending forwardly driven fracture.

[0111] 水力喷射压裂应用于井下软煤主要有喷射和冲孔两个作用。 [0111] Hydraulic fracturing is applied to the downhole injection soft coal main injection and two punching action.

[0112] 第一为喷射对软煤的作用。 [0112] The first effect is a soft coal injection. 在已施工的钻孔中,利用水力喷射对钻孔煤层段孔壁进行打击、破碎煤体,并在一定时间内冲出大量煤体,形成较大直径的孔洞,从而破坏煤体原应力平衡状态,孔洞周围煤体向孔洞方向发生大幅度位移,促使应力状态重新分布,集中应力带前移,有效应力降低;其次煤层中的应力降低打破了瓦斯吸附与解吸的动态平衡,使部分吸附瓦斯转化成游离瓦斯,而游离瓦斯则通过裂隙运移得以排放,大幅度地释放了煤体及围岩中的弹性潜能和瓦斯膨胀能,煤层瓦斯透气性显著提高;最后,高压水润湿了煤体,可降低煤体中残存瓦斯的解吸速率,起到抑制瓦斯涌出作用。 Construction has been drilled, the use of a water jet bore hole wall seam section combat, crushed coal, and large coal out within a certain time, a larger diameter hole is formed, thereby destroying the original coal stress balance status, the occurrence of holes around the coal pores substantial displacement direction, causes redistribution of stress state, with a concentrated stress advance, reducing the effective stress; followed seam stress reducing gas adsorption and desorption breaks the dynamic balance, so that part of the gas adsorbed converted into the free gas, the gas is free to transport discharged through cracks, greatly releasing the elastic potential for gas expansion and surrounding rock and coal energy, coal seam gas permeability significantly improved; Finally, high-pressure water wetted coal body, can reduce the rate of desorption of residual gas in the coal, act to inhibit the action of gas emission.

[0113] 第二为水力冲孔对软煤的作用。 [0113] The second effect of soft coal for hydraulic flushing. 水力喷射过程中,软煤部分冲击到钻孔与喷射管环空处,由于喷射速度大于软煤喷出孔速度,环空处的软煤不断的填充、压实,起到了封孔的效果,本孔只有微量出水,起到了封孔压裂煤层的作用。 The water jet process, some of the impact to soft coal injection pipe and the borehole annulus, the soft coal since the ejection speed is greater than the speed of the ejection hole, annulus soft coal continuously at the filling, compaction, the sealing effect played, this hole only a trace of water, played a role in sealing the fracturing of the coal seam.

[0114] 可以通过两种作业方式使用矿用水力作业机实现水力喷射压裂: [0114] Hydraulic injection may be achieved using mineral water fracturing force working machine operating in two ways:

[0115] 方式一:当钻孔施工完成之后,水力喷射喷头及喷嘴此时接近孔底,可向孔外方向拉动水力喷射喷头及喷嘴,每隔一定距离(如1m)进行低强度较短时间的喷射(可通过高压水泵调节注入流量及压力),以不使连续油管难以拔出为好,通过水力喷射,在孔内内产生较为均匀的射流裂缝。 [0115] Method 1: After the completion of drilling operation, the water jet nozzle and the nozzle case close to the bottom of the hole, can pull the water jet nozzle and the nozzle hole toward the outer direction, low-intensity short time at predetermined distance intervals (e.g., 1m) injection (the injection can be adjusted by a high-pressure pump flow rate and pressure), so as not to pull out the coiled tubing is difficult as well, by a water jet, the jet produced more uniform cracks in the bore. 在接近孔口使,加大喷射的流量及压力,使孔内煤、岩粉由于流动速度没有射流返水速度快而堆积在孔口,封堵住连续油管与钻孔孔壁之间的空隙,此时,进行水力压裂可较为均匀的开启、延伸、沟通裂缝,在较大范围之内增大煤层的透气性系数,提高抽采效率。 Near the aperture so that, to increase the injection flow rate and pressure of the pores of coal, rock dust due to the flow speed is not fast return water jet speed between the deposited aperture closure blocked coiled tubing and drill hole wall clearance at this time, hydraulic fracturing can be performed more uniform opening, extends, communicate cracks, increased seam permeability coefficient in a wide range of improved drainage efficiency.

[0116] 方式二:当钻孔施工完成后,连续油管每向孔口移动一定距离,便进行一次高压大排量的水力喷射压裂,直至孔口。 [0116] Second way: After the completion of drilling operation, coiled tubing each orifice moves a certain distance, will be a high pressure hydraulic jet fracturing large displacement until the aperture.

[0117] 方式一和二均可以实现煤层钻孔的均匀、定点起裂,但由于方式二在实际操作过程中,每退向孔口一次进行压裂,则对其前端的裂缝又进行了一次压裂,这样尽管能够造成更大的裂缝,但由于损失了一定的水流量,在进行本段的水力喷射压裂时可能造缝效果与理想效果偏差较大。 [0117] an embodiment may be implemented uniformly and two seam drilling, crack initiation point, but the second approach the actual operation, each of the fracturing apertures back once the cleave front thereof has conducted a fracturing, although this can cause cracks greater, but due to the loss of a certain amount of water flow, during this period may cause the seam hydraulic fracturing effect ejection effect over large deviations.

[0118] 在硬煤中,水力吞吐压裂使钻孔有效地连通了割理、裂隙,并经过不断的注入压裂液,排除水煤渣,在钻孔周围形成洞穴,使煤储层所受的应力得到释放、应力场重新分布,作用在洞穴上的应力发生了改变,它被部分转移到洞穴的壁面以外,在煤层中形成了指向洞穴的单向负荷,引起煤体因缺乏支撑而向洞穴中移动。 [0118] In the hard coal, hydraulic fracturing in drilling throughput effectively communicate the cleats, cracks, and through continuous injection of a fracturing fluid, cinder exclude water, formed around the hole drilling, coal reservoirs suffered the stress is released, the redistribution of the stress field, the stress acting on the cave changed, it is transferred to a portion other than the cave wall, forming a one-way directed load cave in coal, coal by causing lack of support to the mobile cave. 这种影响向煤层内不断延续,可以扩展到洞穴周围一定范围内,有效的开启、延伸、沟通了裂隙,形成较大范围之内的体积改造。 This effect continue to extend into the coal seam surrounding the cave can be extended to a certain range, the effective opening, extends, communicate the fracture, the volume of the transformation is formed within a larger range. 吞吐压裂增透在形成钻孔洞穴的同时形成4类裂隙:径向引张裂隙、周缘引张裂隙、剪切裂隙和转向裂隙。 Fracturing stimulation through 4 fissure is formed simultaneously with the formation of the borehole cave: radial tensile fracture, tensile periphery of fissures, cracks and shear fracture steering.

[0119] 在软煤中,软煤自身的力学性质决定其不可压裂,通过吞吐压裂,可在软煤层中形成洞穴,起到卸压的作用。 [0119] In the soft coal, the mechanical properties of soft coal itself can not determine their fracturing, fracturing by throughput, caves may be formed in the soft coal seam, the pressure relief functions. 洞穴形成一定空间之后,不能够继续扩展,此时,洞穴内压裂流体压力逐渐增大,压实洞穴周边煤体,形成坚硬、低孔隙度、高应力的压实带,使瓦斯不能快速运移产出。 After a certain cave space, can not continue to expand, at this time, the cave of the fracturing fluid pressure increases, the peripheral caves coal compaction to form a hard, low porosity, compaction with high stress, so that the gas can not be quickly transported shift output. 当形成压实带之后,注入的压裂液难以在煤层中继续流动,出现挤胀与穿刺现象。 After the formation of compact strip, the injected fracturing fluid is difficult to continue to flow in the coal seam, and puncture phenomenon occurs bulge.

[0120] 通过使用水力喷射装备,变排量对钻孔长度内的任意位置实施吞吐压裂,使吞吐压裂钻孔空间范围增大,更有利于钻孔裂缝的均匀开启及卸压,同时,避免了以往吞吐压裂时复杂的封孔工艺,节约了封孔管,节省了时间,创造了效益。 [0120] By using a water jet equipment, implementation of the variable displacement anywhere within the length of the borehole fracturing throughput, so that throughput increases the spatial extent of fracturing the borehole, even more conducive to the relief bore and open cracks, while to avoid the complex process of sealing the past when handling fracturing, saving sealing tube, saving time and create efficiency.

[0121] 在钻孔钻进、增透、修复过程中,矿用水力作业机工作时所需的注入压力及流量的控制,主要是受以下因素的影响:地层压力大小、煤体结构和煤体抗压强度。 [0121] In drilling the borehole, AR, repair process, the injection control pressure and flow required for working mineral water power working machine, mainly influenced by the following factors: the size of the formation pressure, coal and coal structure compressive strength.

[0122] 地层压力大小 [0122] Formation of pressure

[0123] 在使用矿用水力化作业机进行钻进、增透时,由于是在井下进行作业,因此,其所需压力受到上覆地层压力影响,喷嘴出口压力可以由以下公式进行确定: [0123] In use of mineral water power working machine for drilling, when the AR, since the operation is performed downhole, and therefore, the required pressure by the overlying formation pressure influence, outlet pressure of the nozzle may be determined by the following equation:
