Introduction to Stuck Pipe | Drilling Course
Feb 26, 2016 · Poor hole cleaning can lead to drilled cuttings accumulation into the annulus causing stuck pipe. This problem can be more difficult when drilling deviated wells. The cutting beds can form on the low side of the well bore.How to distinguish the thread of oil pipeline?Because of this type easily lead to stress concentration, API has gradually replaced it. FH(Full-hole style connection) This type of joint screw connects inside and outside thickened drill pipe, forming the inner diameter of the drill pipe joint is equal to thickened end diameter and they are smaller than the inner diameter of the pipe.Some results are removed in response to a notice of local law requirement. For more information, please see here.Hole geometry - PetroWiki - Oil&GasThe drilling industrys experience has developed several commonly used hole-geometry programs. These programs are based on bit- and casing-size availability as well as the expected drilling conditions. Deep, high-pressure wells often require deviations from common geometries. Reasons include: 1. Prolific production rates requiring large tubing strings. 2. Drilling problems requiring the use of an intermediate string and one or more liners. 3. Tension design problems because thick-walled pipe mSee more on petrowiki.spe.org

They are typically a 31 foot long section of tubular pipe but may be anywhere from 18 to 45 feet in length. Heavy weight drill pipe (HWDP)is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to See more on equipoutlet api petroleum pipe Hole drilling

Because we manufacture the raw material of petroleum drilling products ,we have more price advantage and quality control ability than any other petroleum drilling equipments manufacturers.API | Advanced Drilling TechniquesHorizontal drilling starts with a vertical well that turns horizontal within the reservoir rock in order to expose more open hole to the oil. These horizontal "legs" can be over a mile long; the longer the exposure length, the more oil and natural gas is drained and the faster it can flow. More oil and natural gas can be produced with fewer wells and less surface disturbance. However, the technology only can be employed in certain locations.See more on api.org
