Abstract
An oriented perforating device used in oil field comprises a rotary joint 2, an upper leaning-type device 4, a direction adjusting joint 5, an oriented perforating gun 6 and a lower leaning-type device 8, wherein, an oil pipe 1 is connected with the rotary joint 2 and a piezo ignition head 3 in turn; the upper part of the direction adjusting joint 5 is provided with the upper leaning-type device 4, while the lower part is provided with the lower leaning-type device 8; the middle part of the oriented perforating gun 6 is provided with a middle joint 7. As for inclined shaft, gyroscope is not necessary to detect the direction and only a rotary joint and two leaning-type devices are enough to make perforating gun accord with the inclined direction of shaft body. During use, by means of given shaft body orientation data and stratum perforating direction, loading direction can be adjusted before entering into shaft and ignition and perforation can be realized just after depth check in underground. The utility model can reduce cost of oriented perforation and simplifies on-site operating procedure to reduce uphole time.
Description
Relate to the field
The utility model relates to the perforating system that use in a kind of oil field, specifically, is the oriented perforating device.
Background technology
When drilling oil, gas-bearing formation, the permeability of oil, gas-bearing formation is not to be isotropic around the borehole axis: the fracture development direction of carbonate formation, sedimentary rock stratum joints development direction, minimum its permeability of stress direction (downbeam during deposition) in glutenite stratum are better than other direction far away.If can allow perforating bullet only penetrate towards the best direction of permeability during perforation, the production capacity of oil, gas-bearing formation will be multiplied.
Oriented perforating is to utilize gyroscope to measure the orientation of perforating gun head in sleeve pipe, adjusts the directive of bullet then.
Can access crack, joints development direction or the minimum stress direction of each oil, gas perforated zone and the angle between the magnetic north pole direction from the well log interpretation data, orientation with the rifle head is magnetic north pole direction (0 °), by the transmit direction of above-mentioned angle assembling perforating bullet.First school is dark after going into the well, and uses the direction of gyroscope survey rifle head again, and oil pipe carries oriented perforating to need make rifle head aligned magnetic direction to the north pole at the well head rotation pipeline, calibrates the perforation of can lighting a fire repeatedly with gyroscope.Cable carries oriented perforating to go into the well for the first time with gyroscope survey rifle head direction, proposes the directive that well head is adjusted bullet, removes the gyroscope secondary perforation of can lighting a fire of going into the well.
The straight well oriented perforating can utilize the direction of the gyroscope survey perforating gun head that " directional well " operation uses, need join the directed linkage of a spiral above the rifle head, go into the well operation procedure and plain tubing perforation is basic identical, only need after the calibration degree of depth, with cable gyroscope is lowered to oil pipe and above the rifle head, is connected with the directed linkage of spiral.Go out the direction of rifle head with gyroscope survey, make the orientation of rifle head consistent at the well head rotation pipeline with magnetic north pole.Proposing gyroscope then can caber or pressurization igniting perforation.
Gyroscope is quite accurate logger, the sharp pounding when being unable to undergo perforation, and on-the-spot to take the well site time when measuring longer, and because of the instrument service fee height that costs an arm and a leg, strengthened the cost of oriented perforating.
Technology contents
The purpose of this utility model is to provide a kind of perforating gun and well bore of making oblique consistent, make full use of the required directive of known well bore bearing data and stratum, mix up before going into the well and shoot direction, the school perforation of can lighting a fire after dark of going into the well, can reduce the cost of oriented perforating and simplify the execute-in-place program again, reduce the oriented perforating device that takies uphole time.
The utility model is achieved in that and comprises oil pipe 1, swivel joint 2, pressure spot duration and degree of heating 3, upward inclined to one side to device 4, tuning joint 5, oriented perforating rifle 6, transition joint 7, following device 8, the gun breech 9 of leaning on partially, oil pipe 1 is connected successively with swivel joint 2, pressure spot duration and degree of heating 3, be provided with partially by device 4 on the top of tuning joint 5, be provided with down partially by device 8 in the bottom of tuning joint 5, there is transition joint 7 centre of oriented perforating rifle 6,, tail rifle 9 is arranged in the bottom of device.
The utility model also adopts following technical scheme:
Go up partially by device 4, down partially by device 8 by body 10, block 11, slideway 12, lever pin 13, latch plate 14, brake pad 15, screw 16, set upright plug 17, back-up ring 18 is formed, plug 17, back-up ring 18 and block 11 are set upright in the two ends of body 10, slideway 12 runs through body 10, and latch plate 14 two ends are fixing with lever pin 13.
Be to seal oiling between the swivel joint 2 upper and lower movable heads.
Advantage of the present utility model is: for inclined shaft, can survey direction without gyroscope, adopt a swivel joint just can make perforating gun and well bore oblique consistent by device partially with two.The required directive of well bore bearing data and stratum that utilizes oneself to know mixes up before going into the well and shoots direction, the perforation of can lighting a fire after the school of going into the well is dark.Can reduce the cost of oriented perforating and simplify the execute-in-place program again, reduce taking uphole time.
