Description

一种涡轮压裂半挂车Turbine fracturing semi-trailer 技术领域Technical field
本发明涉及油气田作业领域，具体涉及一种涡轮压裂半挂车。The invention relates to the field of oil and gas field operations, in particular to a turbine fracturing semi-trailer.
背景技术Background technique
在全球的油气田压裂作业现场，压裂设备的驱动方式主要有两种：In the global oil and gas field fracturing operation sites, there are two main driving methods for fracturing equipment:
第一种驱动方式柴油发动机驱动，具体的方案是柴油发动机连接变速箱经传动轴驱动压裂柱塞泵工作。也就是说，动力源是柴油发动机，传动装置是变速箱和传动轴，执行元件是压裂柱塞泵。.The first driving mode is diesel engine driving. The specific scheme is that the diesel engine is connected to the gearbox and drives the fracturing plunger pump through the drive shaft. In other words, the power source is a diesel engine, the transmission device is a gearbox and a drive shaft, and the actuator is a fracturing plunger pump. .
该配置模式存在以下缺点：The configuration mode has the following disadvantages:
(1)、体积大重量大：柴油机驱动变速箱经传动轴驱动压裂柱塞泵，体积大，重量大，运输受限，功率密度小。(1) Large size and weight: The diesel engine drives the gearbox via the drive shaft to drive the fracturing plunger pump, which is large in size, heavy in weight, limited in transportation, and low in power density.
(2)、不环保：柴油发动机驱动的压裂设备在井场运行过程中，会产生发动机废气污染和噪音污染，噪音超过105dBA，严重影响周围居民的正常生活。(2) Not environmentally friendly: Diesel engine-driven fracturing equipment will produce engine exhaust gas pollution and noise pollution during the operation of the well site. The noise exceeds 105dBA, which seriously affects the normal life of surrounding residents.
(3)、不经济：柴油发动机驱动的压裂设备，设备初期的采购成本比较高，设备运行时单位功率燃料消耗费用高，发动机和变速箱的日常维护保养费用也很高。(3) Uneconomical: For fracturing equipment driven by diesel engines, the initial purchase cost of the equipment is relatively high, the cost of fuel consumption per unit power during the operation of the equipment is high, and the daily maintenance costs of the engine and gearbox are also high.
第二种驱动方式是电驱压裂，具体的方案是电动机连接传动轴或者联轴器驱动压裂柱塞泵工作。也就是说，动力源是电动机，传动装置是传动轴或者联轴器，执行元件是压裂柱塞泵。The second driving method is electric fracturing. The specific scheme is to connect a motor to a drive shaft or a coupling to drive the fracturing plunger pump. In other words, the power source is an electric motor, the transmission device is a drive shaft or coupling, and the actuator is a fracturing plunger pump.
电驱压裂本身虽然有很多优点，但是压裂井场的供电是电驱压裂实施 的先决条件。通常情况下，压裂井场的供电问题并不好解决。要么井场的电网容量太小，带不动整个压裂机组；要么就是井场根本没有电网。所以常见的电驱压裂现场通常会使用发电机发电，最经济的发电燃料是采用天然气，但采用天然气需要用户租用或者购买燃气发电机组。对于一个没有电网的压裂井场来说，燃气发电机组的功率至少需要达到30MW，这对客户来说，购进如此大功率的燃气发电机组是笔不少的投资。更重要的是实际施工过程中因为燃气发电机组故障停机，则整个电驱压裂机组都会瘫痪，严重影响作业质量甚至还可能会导致作业事故。Although electric fracturing itself has many advantages, the power supply of the fracturing well site is a prerequisite for the implementation of electric fracturing. Under normal circumstances, the power supply problem of the fracturing well site is not easy to solve. Either the grid capacity at the wellsite is too small to drive the entire fracturing unit; or there is no grid at the wellsite. Therefore, common electric drive fracturing sites usually use generators to generate electricity. The most economical power generation fuel is natural gas, but the use of natural gas requires users to rent or purchase gas-fired generator sets. For a fracturing well site without a power grid, the power of the gas generator set needs to reach at least 30MW. For customers, purchasing such a high-power gas generator set is a lot of investment. More importantly, during the actual construction process, due to the failure of the gas generator set, the entire electric drive fracturing unit will be paralyzed, which will seriously affect the quality of the operation and may even cause an operation accident.
为此亟待一种新的压裂设备，解决上述现有柴油发动机驱动压裂和电驱压裂的缺点，可以更好的满足全球油气田压裂市场的需求。Therefore, a new type of fracturing equipment is urgently needed to solve the above-mentioned shortcomings of the existing diesel engine driven fracturing and electric drive fracturing, which can better meet the needs of the global oil and gas field fracturing market.
发明内容Summary of the invention
本发明的目的克服现有技术的不足，提供一种涡轮压裂半挂车，通过涡轮发动机，减速箱，传动机构和柱塞泵沿着动力传动方向上的直线连接，可避免过多的传动损耗，保证高效的传动性能。涡轮发动机本身具有体积小、重量轻、功率密度大的优势，同样的外形尺寸和重量，涡轮压裂设备的单机功率是常规柴油机压裂设备的2倍以上。涡轮发动机可以直接100％以天然气为燃料，相对于柴油驱动中的柴油消耗，以及电驱压裂设备中的燃气发电机组投资，大大降低了使用成本。同时，涡轮压裂设备通常是与柱塞泵一对一驱动工作，不像电驱压裂设备中由单台大功率燃气发电机组驱动多个柱塞泵，即采用涡轮压裂设备可以把单台大功率燃气发电机的故障风险均摊到每台涡轮压裂设备上。避免了单台燃气发电设备故障导致全套压裂车组瘫痪的风险。The purpose of the present invention overcomes the shortcomings of the prior art and provides a turbo fracturing semi-trailer, which can avoid excessive transmission loss by connecting the turbo engine, the reduction box, the transmission mechanism and the plunger pump along the power transmission direction in a straight line. , To ensure efficient transmission performance.

The turbine engine 7 is a whole The power source of the vehicle power transmission system, the turbine engine 7, the reduction box 8, the transmission mechanism and the plunger pump 10 are arranged on the semi-trailer body 3, and the semi-trailer body 3 can also be arranged with battery cables, fuel tanks, and lubricating oil tanks. , Hydraulic oil tank and other components, provide oil and support for the turbo engine 7, reduction box 8, plunger pump 10 and other top-mounted components. The output end of the turbine engine 7 is connected to the reduction box 8, and the reduction box 8 and the plunger pump 10 pass through The transmission mechanism is connected in transmission. The reduction box 8 is used to reduce the speed and increase the power output of the turbine engine 7 and then drive the plunger pump 10 through a transmission mechanism to work.
所述涡轮发动机7在连接减速箱8的相对侧设有排气系统，所述排气系统包括排气消音器4和排气管道5，所述排气消音器4通过排气管道5与涡轮发动机7的排气口连通。排气管道5用于将涡轮发动机7排气引导至排气消音器4内，排气消音器4可降低排气噪音。The turbine engine 7 is provided with an exhaust system on the opposite side connected to the reduction box 8. The exhaust system includes an exhaust muffler 4 and an exhaust duct 5. The exhaust muffler 4 is connected to the turbine through the exhaust duct 5 The exhaust port of the engine 7 communicates. The exhaust duct 5 is used to guide the exhaust of the turbine engine 7 into the exhaust muffler 4, and the exhaust muffler 4 can reduce exhaust noise.
所述排气系统、涡轮发动机7、减速箱8，传动机构和柱塞泵10沿着动力传动的方向设在同一条直线上。通过涡轮发动机7，减速箱8，传动机构和柱塞泵10沿着动力传动方向上的直线连接，可避免过多的传动损耗，保证高效的传动性能，并且这样的排布安装可降低半挂车体上设备的重心高度，方便运输。涡轮发动机7本身具有体积小、重量轻、功率密度大的优势，同样的外形尺寸和重量，涡轮压裂设备的单机功率是常规柴油机压裂设备的2倍以上。涡轮发动机7可以直接100％以天然气为燃料，相对于柴油驱动中的柴油消耗，以及电驱压裂设备中的燃气发电机组投资，大大降低了使用成本。当然涡轮发动机7也可以100％以燃油为燃料，优选为天然气，可以比燃油更降低燃料成本。同时，涡轮压裂设备通常是与柱塞泵10一对一驱动工作，不像电驱压裂设备中由单台大功率燃气发电机组驱动多个柱塞泵10，即采用涡轮压裂设备可以把单台大功率燃气发电机的故障风险均摊到每台涡轮压裂设备上。避免了单台燃气发电设备故障导致全套压裂车组瘫痪的风险。The exhaust system, the turbine engine 7, the reduction box 8, the transmission mechanism and the plunger pump 10 are arranged on the same straight line along the direction of power transmission. The turbine engine 7, the reduction box 8, the transmission mechanism and the plunger pump 10 are connected in a straight line in the power transmission direction, which can avoid excessive transmission loss, ensure efficient transmission performance, and such arrangement and installation can reduce the semi-trailer The height of the center of gravity of the equipment on the body is convenient for transportation. The turbine engine 7 itself has the advantages of small size, light weight, and high power density. With the same external dimensions and weight, the single engine power of the turbine fracturing equipment is more than twice that of the conventional diesel fracturing equipment. The turbine engine 7 can directly use 100% natural gas as fuel, which greatly reduces the use cost compared with the diesel consumption in diesel driving and the investment of gas generator set in electric drive fracturing equipment. Of course, the turbine engine 7 can also be 100% fueled by oil, preferably natural gas, which can lower fuel costs than fuel. At the same time, the turbo fracturing equipment is usually driven one-to-one with the plunger pump 10, unlike the electric drive fracturing equipment, which is driven by a single high-power gas generator set to drive multiple plunger pumps 10, that is, the turbo fracturing equipment can be used to drive multiple plunger pumps 10 The failure risk of a single high-power gas generator is equally distributed to each turbine fracturing equipment. The risk of the failure of a single gas-fired power generation equipment causing a complete set of fracturing vehicles to be paralyzed is avoided.
