The working principle of hydraulic drilling equipment

图片
Generally, a   hydraulic drilling machine   spread has a smaller footprint than a conventional drilling rig. This is, in part, because hydraulic drilling usually involves smaller hole sizes requiring smaller drill string diameters, smaller OD and lighter BHAs, and smaller mud systems and pumps that require only the circulation rates necessary to clean the hole. All of this means less areal space is required on the wellsite for the equipment spread.   Less equipment, lower pump rates, and smaller horsepower requirements also mean less fuel consumption and fewer air emissions. There is less equipment on the location, so exposure risk to leaks or spills is reduced. Smaller hole sizes also mean that a smaller cuttings volume must be handled, and the risk of a cuttings spill is also reduced.   The snub drilling spread may be required to drill the same size holes as the conventional drilling rig. It does not have a substructure and mast, however, and most of the other equi...

Dig Your Own Water Well

图片
Drilling a well by hand is a lot of work, but it can be done with the right equipment. Whether you ’ re looking to drill a shallow or deep well, this skill is perfect for those seeking self-reliance.   Dig Your Own Water Well Wells are normally drilled on private land where city or rural water isn ’ t available. It ’ s possible to hire a licensed professional to provide this service but you can expect to spend several thousand dollars. If you want to save money, you can do it yourself, but prior to getting started, you need to research local regulations.   Each state or county will have its own list of requirements and regulations. These can be found online or at your county courthouse. When asking about these regulations, make sure you explain that you will be drilling the well yourself and on your own land.   Once you receive a green light to move forward, it ’ s time to learn more about your land. Go to the county agriculture extension office to find out what soil type...

Choosing the right drilling rig

图片
  You could need a drilling rig for a multitude of applications, for example to drill a well to access a natural resource (water, oil, geothermal energy, etc.), to build foundations, to make blasting holes in a mine, to take samples from the ground, etc.   It is necessary to determine what the drilling rig will be used for, as well as what kind of terrain it will mainly be operating on. Depending on the terrain, you can choose between different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammer), etc.   In order to make the best choice, it is important to determine whether the drilling rig will be used for your core business or for occasional operations, and in particular whether you want to take advantage of the latest innovations or whether a machine that has proven its worth over several decades might be suitable for you.   Safety, reliability and ease of use are also impo...

Five Most Common Drilling Methods Used in Oil and Gas Exploration

图片
Oil and ga s exploration makes use of several types of drilling methods and platforms based on the type of formations, geographic location, soil type and the like. Here are five of the most common drilling methods used in extracting oil and gas from beneath the earth:   Percussion or Cable Drilling Rotary Drilling Dual-Wall Reverse-Circulation Drilling Electro-Drilling Directional Drilling   Percussion or Cable Drilling Percussion drilling is an oft-used manual drilling technique in which a hammering bit is attached to a long cable that is then lowered into a wide open hole. The technique is also known as cable drilling, wherein the driller uses a tripod to support the tools. By going back and forth with the bit, the action loosens the soil in the borehole, which is then extracted with the help of a bailer. At intervals, the bit is removed while the cuttings are suspended in water, which is then removed by pumping to the surface. A steel casing helps prevent the hole from coll...

How to Choose Drill Bits In Borehole Drilling Machine Construction?

  1. The main function of   Advanced Crawler Mounted DTH Drilling Rig  is to dig holes on the surface. Due to the different depths of the pile holes to be constructed, various terrain structures will be encountered during drilling. It can be roughly divided into the following categories: (1) Clay: Use a rotary drilling bucket with a single bottom. If the diameter is small, use a two-part bucket or a bucket with a soil unloading plate. (2) Silt, low-cohesive soil layer, sandy soil, and poorly cemented pebble layer with a small particle size can be equipped with a double-bottom drilling bucket. (3) Hard clay: Use a rotary drilling bucket with a single inlet (single and double bottoms), or a bucket tooth straight screw. (4) Frozen soil layer: Bucket-tooth straight spiral drill bucket and rotary drilling bucket with low ice content can be used, and cone spiral drill bit with high ice content can be used. It should be noted that spiral drill bits are used for soil layers (exce...

How to Pay Attention to the Maintenance of Each System of Crawler Drilling Rig?

  How to pay attention to the maintenance of various systems of   hydraulic drill rigs ? The following   hydraulic DTH Drilling Rig Supplier  will explain the maintenance of each system of crawler drilling rigs. Cooling system: Regularly check the working condition of the engine cooling system to ensure that the cooling system has complete parts and good performance. In particular, check the performance of the cooling pump, the tightness of the fan tape, whether the vents and vents of the radiator cover are unblocked, and whether the coolant is Adequacy, whether the thermostat and fan clutch are in a good performance, etc. Clean the dust and sludge on the air-cooled engine cylinder liner radiator and radiator in time, and clean the scale and impurities in the water radiator of the water-cooled engine in time. Electrical system: Regularly check whether the terminal is loose, whether the wire ends and contacts are oxidized or ablated. It is necessary to adjust the gene...

Bearing Use of Crawler Down-the-Hole Drill

图片
  Bearings are familiar to everyone and are closely related to our lives and work. From bicycles to automobiles or construction machinery, there are bearings, and Drilling Rig is inseparable from them. The bearings of the   Advanced Crawler Mounted DTH Drilling Rig   are precision parts, and they must be maintained in daily work to make it more effective. Pay attention to the following points when using bearings. When installing the bearing, do not press hard, do not use a hammer or other hard objects to strike, and do not transmit pressure through the rolling elements; use professional tools when installing, do not brute force; usually keep the rotary excavator bearing clean, Even a trace of dust may cause bearing wear; the bearings of rotary excavators should be treated with rust prevention. The bearing is a precision part of the crawler drilling rig. The damage of one small thing will cause the failure of the entire crawler drilling rig. Therefore, we must pay att...
