Abstract
Disclosed by the utility model is a kind of small casing pipe well Drilling rod for well-drilling that petroleum industry workover treatment uses, and has enough tension and torsional strength and good anti-fatigue performance.This Drilling rod for well-drilling includes drilling rod ontology, the both ends of drilling rod ontology are female adapter end and male connection end respectively, the outer diameter of drilling rod ontology is set between 59mm -62mm, and the outer diameter at female adapter end and male connection end is set between 71mm -76mm.The utility model do not reduce go into the well drilling rod tubing string bonding strength under the premise of, increase the gap between drilling rod outer diameter and casing inner diameter, facilitate and carry out all kinds of construction operations, disclosure satisfy that the overhaul of downhole oil well, operation sidetracking, salvaged the requirements such as drilling rod and the exploration of geology well.
Description
Technical field
The utility model relates to a kind of workover treatment tool of petroleum industry, especially a kind of small casing pipe well well workover
Drilling rod has enough tension and torsional strength and good anti-fatigue performance.
Technical background
Small casing production technique is the new technology that petroleum industry promotes and applies in recent years, and it is inadequate to still have process matched therewith at present
Ripe perfect problem, general API standard drilling rod is difficult to meet mating well workover requirement, in existing mating drilling rod, standard
23/8" tool joint outer diameter 85.7mm cannot be satisfied the requirement in tripping in Φ 95mm sidetracked casings.
Invention content
The purpose of this utility model is to provide a kind of small casing pipe well Drilling rod for well-drilling, facilitates construction in tripping in small casing, solution
The problem of certainly small casing pipe well Drilling rod for well-drilling matches, improves macaroni process matched therewith.
The technical solution of the utility model is：A kind of small casing pipe well Drilling rod for well-drilling includes drilling rod ontology, drilling rod sheet
The both ends of body are female adapter end and male connection end respectively, the outer diameter of drilling rod ontology be set in 59mm -62mm it
Between, the outer diameter at female adapter end and male connection end is set between 71mm -76mm.
The utility model has the beneficial effects that：The utility model is in the premise for not reducing drilling rod tubing string bonding strength of going into the well
Under, optimize the outer diameter of drilling rod ontology and both ends female adapter end and male connection end, increase drilling rod outer diameter with
Gap between casing inner diameter facilitates and carries out all kinds of construction operations.It is proved by Physicochemical test, the utility model has enough
Tension and torsional strength and good anti-fatigue performance, disclosure satisfy that the overhaul of downhole oil well, operation sidetracking, salvage drilling rod and
The requirements such as geology well exploration, can adapt to the requirement of workover process in small casing pipe well, and guarantee is provided for well workover construction, perfect
Macaroni process matched therewith.
