Description
Technical field
A kind of drilling equipment field is the utility model is related to, more particularly to a kind of high security water conservancy drilling equipment.
Background technology
The work that stratum is drilled to eyelet using plant equipment or manpower from ground is referred to as drilling well.It is often referred to explore or develops
The liquid such as oil, natural gas and gaseous state mineral products and Drilling well and the engineering of major diameter water supply well.Drilling well is in the development of the national economy
In application it is extremely wide.Oily (gas) field in China widely uses rotating disk and bores drilling well at present.Capital equipment have derrick, operating platform,
Diesel engine, rig, drilling tool, slush pump, generator and test equipment and fuel oil drum, boiler etc..Drilling well diameter and depth are big
It is small, depending on drilling well purposes and mineral products buried depth etc..Drill for oil, the drilling well diameter of natural gas and underground water it is all larger.
Mainly function is：Obtain underground geological material, i.e., taken from drilling well core drilling obtain rock core, the ore deposit heart, landwaste, liquid
Sample, gaseous state sample etc..As geophysical log passage, the data of the acquisition various geophysical fields of rock ore bed.As artificial channel
Observe water table hydrogeology current intelligence.As visiting, adopting combination, tap ground water resources, the drilling well of oil gas, underground heat etc..Drilling well
Generally it is divided into geologic prospecting or exploration drilling, hydrogeology drilling, well or engineering geology drilling well, geothermal drilling, stone by purposes
Oily drilling well, coal driling, ore field drilling well, building ground drilling well etc..A bite well need to carry out following three mainly from spudding in completion
Work：1. broken bottom rock；2. by fragmented rock (i.e. landwaste) migration to ground；3. consolidate the borehole wall (referred to as cementing the well).
Bore, also known as impact drill.Cable tool bit is sent to shaft bottom with steel wire rope, by power drive walking beam mechanism, walking beam one end is transported up and down
It is dynamic, and drive steel wire rope and drill bit to produce percussion up and down, make catalase.Percussion drill drilling speed is slow, and efficiency is low, it is impossible to adapts to day
The drilling requirements of the increased well depth of benefit and bad ground, are gradually replaced by rotary drilling.But it has equipment simple, and cost is low, not dirty
The advantages that contaminating oil reservoir, the low pressure Oil/gas Well shallow available for some, absorption well etc..Using cutting caused by bit or grind
Act on fractured rock.It is current most general boring method.It is faster than percussion drill drilling speed, and it is easily handled the complicated feelings such as well slough, blowout
Condition.By power delivery mode, rotary drilling can be divided into rotating disk and bore and two kinds of underground power drilling again：Rotating disk is drilled at the well head of rig floor and filled
Rotating disk is put, there is square hole center of turntable part, and the kelly bar of drill string upper end passes through the square hole, drill string and drill bit are connect under kelly bar, moves
Drill string and drill bit is driven to rotate together during power driving rotating disk, fractured rock.Underground power drilling is driven using mud motor
Drill bit fractured rock, drill string does not rotate during drilling, and abrasion is small, particularly suitable for digging a directional well.Well dynamic is drilled with turbine brill, screw rod
Brill and electric drill etc..It is exactly water in ground, oil maximum during drilling well the problem of and gas is unconfined pours into drilling well and set
It is standby internal, danger is caused, existing technology is difficult to solve problem above.
