How long is a borehole pipe?
The push-on coupling pipes are available in 6m and 3m lengths.
How is drill pipe length measured?
The sensor is mounted in a collar at the top and continually measures the distance to the platform until the process is complete. Laser sensors measure the real time length of each pipe as it is drilled into the ground. The length measurement of the pipe is used to measure the total depth the pipes are into the ground.
What size is drill stem pipe?
2 3/8”, 2 7/8” and 3 1/2” Drill Pipe for Common Use. In API 5DP specifciations, the common use OD are 2 3/8”, 2 7/8” and 3 1/2” drill pipes, these usually required in large amount of quantities in drilling activities.
How long is oil well pipe?
Drill pipe is manufactured normally under specifications of the American Petroleum Institute (API). The lengths of the “joints” are specified in these specs, and are commonly approximately 30 to 31 feet in length.
What is the length of the drilling pipe?
27 to 32 feet
Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2).
How much does borehole drilling cost in South Africa?
The Borehole Water Association of South Africa says the average drill cost is around 600 a meter, but this can be as much as R900 per meter depending on the company. “Yield testing will set you back somewhere between R2,000 and R5, 000 while the equipment might cost between R20, 000 and R40, 000.
How long is a length of drill pipe?
It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
How long is Range 2 drill pipe?
Drill pipe tubes are furnished in the following API length ranges: Range 1: 18-22 ft; • Range 2: 27-30 ft; • Range 3: 38-45 ft.
How many Metres is a drilling pipe?
A length of pipe, usually referring to drillpipe, casing or tubing. While there are different standard lengths, the most common drillpipe joint length is around 30 ft [9 m].
What is the most common range of drill pipe?
Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
What is the ideal depth of a borehole?
The depth to be drilled should be at least 40 metres and at least six (6) meters below the main aquifer to provide proper installation of a hand pump and to provide a sand trap of 3 meters.
How long does it take to drill a borehole?
1 to 2 days
The length of time required to drill a borehole depends on the required depth of the borehole as well as the underlying geology of the site. A general guideline is 1 to 2 days for the completion of the drilling process.
What is the minimum diameter of a borehole?
It is prudent to drill the borehole somewhat larger than the minimum diameter as a precautionary measure. Therefore, for the design shown as Figure 1, the recommended borehole diameter is 34 inches.
What is involved in the borehole drilling process?
1. Siting the borehole location – It’s basically locating the best spot to drill a borehole that will have the best performance and water quality at the lowest cost possible. 2. Mobilisation and Demobilisation – Machinery, equipment and materials need to get to the site to be set up.
How long does it take to test a borehole?
In the case of boreholes with indicative yields of between 500 and 1500 liters per hour, the borehole will be tested at a constant discharge rate of 1000 liters per hour for a minimum period of three (3) hours or until the water level stabilizes
How do you increase the yield of a domestic water borehole?
Maximum yield is achieved by increasing the abstraction rate, ensuring optimum drawdown of water in the borehole. The kind of pumping system and piping installed in your new domestic water borehole will largely depend on the intended use of the borehole water.
