Description
Technical field
The invention belongs to oil servicing unit field, especially relates to the inner slot of a kind of petroleum casing pipeDevice.
Background technology
In the drilling operation of oil, cutting seam sieve tube is important equipment, is usually used in completion or oil recovery in advanceSand control. Cutting seam sieve tube with its good rigidly, anti-scratch mill, gap is even, recovery ratio is high and more anti-than other modesThe advantages such as sand is effective are widely used.
Cutting seam sieve tube is generally on steel alloy petroleum casing pipe, to cut out 7,000 to more than 10,000 to breakInterrupted continuous and for the narrow slit of filter sand.
And the traditional section seam type of cutting seam sieve tube is divided into rectangular slits and trapezoidal seam.
Rectangular slits (claiming again vertical masonry joint) is that the inside and outside wall gap of pipe is equally wide, and the tube wall strength after processing is high,But oil is being mingled with fine sand easily to be stopped up from time in the inflow pipe of gap, and oil recovery efficiency is low, stop up seriousTime can cause the accidents such as well of collapsing.
Trapezoidal seam section is narrow and wide at interior wall opening at tube outer wall opening, and shape is isosceles trapezoid. TrapezoidalSewer has stronger " self-cleaning " effect, and gravel enters behind seam chamber, is easy to be washed away by fluid, is difficult for shapeBecome sand plug, so the inside and outside pressure drop of pipe is little, tar productivity is high, and sand controlling result is good.
There are two kinds but process at present cutting seam sieve tube both at home and abroad: Laser Processing, milling cutter processing, these two kinds of sidesMethod is from petroleum casing pipe outside and processes, thereby can cause a lot of realistic problems.
The shortcoming of Laser Processing is: laser belongs to hot-working, and after processing, the surface roughness value of seam is high, tableFace quality is poorer than machined, easily causes liquid flowing resistance; Affect the many factors of suface processing quality, holdEasily cause body surface blast hole, burn the defects such as seam, cross sectional shape irregularity, inner dross; Due to laserThe restriction of bundle focal position, is easy to occur that body out-seam width dimensions is larger than inseam, when use, easily makesBecome sand plug. And the shortcoming of milling cutter processing is: cutting axis is cantilevered axle, and when cutting, circular runout easily causesBreaks down, blade life is short, and working (machining) efficiency is low; The rotation of blade can not meet and exceed pipeInner wall surface, so joint-cutting out-seam is longer than inseam, leave arc steps, when screen casing uses, easily form sandStifled.
