Description
Technical field
The utility model relates to the drilling tool of a kind of petroleum industry, particularly a kind of well workover sidetracking drilling rod, there is enough tensions and torsional strength and good anti-fatigue performance.
Background technology
Along with Exploration Domain constantly expands, deep-well, ultradeep well are on the increase, and the geological form of down-hole becomes increasingly complex, and engineering requires more and more higher, and borehole condition is more and more harsher, slim-hole, High angle, and horizontal well is increasing.And the hydraulic parameter of drilling well is more and more prominent, along the contradiction that journey pressure consumption is the most too small with bit HHP in drilling rod.This just requires that drilling rod needs enough tensions and torsional strength, has good fatigue resistance, has longer service life.Tool joint meet tension and antitorque on the basis of, external diameter is the least, and hydrophthalmia is big as far as possible, to solve the difficult problem that pump pressure is high, discharge capacity is little.The drilling rod of normal conventional can not meet current drilling well needs, it is necessary to determined the parameter of drill pipe body, joint and the hydrophthalmia of optimum by elevation computation and tension torsional strength etc..Reaching mechanical strength and hydraulic parameters is optimum, to adapt to various unconventional drilling well and the enforcement of Special Drilling Operation technique, safety and speed-raising for drilling well put forward effect and provide safeguard.
Summary of the invention
The purpose of this utility model is to provide a kind of well workover sidetracking drilling rod, and by parameter determination drilling rod body, female adapter end and the parameters of male connection end such as elevation computation and tension torsional strengths, safety and speed-raising for drilling well provide safeguard.
Technical solution of the present utility model is: a kind of well workover sidetracking drilling rod includes drilling rod body, the two ends of drilling rod body are female adapter end and male connection end respectively, the outside dimension of drilling rod body is set between 76mm-80mm, and the outside dimension of female adapter end and male connection end is set between 103.8mm-105.8mm；The internal diameter size of drilling rod body is set between 57mm-61mm, and the internal diameter size of female adapter end and male connection end is set between 57mm-59mm.
Compared with existing drilling rod, remarkable result of the present utility model is: by this utility model of the parameter determinations such as elevation computation and tension torsional strength, male connection end and female adapter end meet tension and antitorque on the basis of, external diameter is the least, its internal diameter is big as far as possible, and the mechanical strength being dimensioned such that drilling rod of drilling rod body, female adapter end and male connection end and hydraulic parameters are optimum.According to job requirements, this utility model bores construction inside slim-hole pit shaft, can replace API standard φ 73mm drilling rod, this drilling rod is compared with API standard φ 73mm drilling rod, because its internal diameter is big, discharge capacity is big, frictional resistance is little, and when can reduce sidetracking, the discharge capacity loss of drilling fluid in drilling rod, reduces frictional resistance, promote drilling speed, shorten drilling period.Being proved by field experimentation, this utility model has enough tensions and torsional strength, has good fatigue resistance, has longer service life.Can adapt to various unconventional drilling well and the requirement of Special Drilling Operation technique, safety and speed-raising for drilling well put forward effect and provide guarantee.
