Description
Technical field
The utility model belongs to field of petroleum exploitation, relates generally to a kind of orientation and decides the firing angle perforating gun, relates in particular to the firing mount of the perforating bullet the adjusted firing angle that a kind of perforating gun uses.
Background technology
When drilling oil, gas-bearing formation, the permeability of oil, gas-bearing formation is not to be isotropic around the borehole axis: downbeam is maximum stress direction when the fractuer direction of carbonate formation, sedimentary rock ground bedded joint direction, glutenite stratum deposition, also claim principal direction of stress, its permeability is much better than other direction.If can allow perforating bullet towards the both direction perforation of good penetrability during perforation, the production capacity of oil, gas-bearing formation will obviously increase.
The straight well oriented perforation is with oil pipe perforating gun to be carried to go into the well, calibrate the degree of depth earlier, adjust tubing string, again with gyroscope from the oil pipe down to the orientation joint at perforating gun top, the orientation is consistent with the sliding embedding connection of its orientation key for the guide that makes the gyroscope lower end, go out the orientation angles of orientation key then with gyroscope survey, because the directive that the orientation rifle in the top is shot is consistent with the direction of orientation key, press the poor of main stress bar orientation, perforation layer position and institute's interception angle, employing is in the way of well head rotation perforation tubing string, allow the orientation key aim at perforation layer position principal direction of stress and carry out perforation, Here it is straight well oriented perforation.Each oil field all adopts this perforating technology to carry out perforating job at present.
As everyone knows, underground oil, gas-bearing formation majority are not levels, and two parameters in its available incline direction and angle of inclination are explained, and are called for short ' tendency ' and ' inclination angle '.In addition, ' tendency ' on the principal direction of stress on stratum and stratum also majority is oblique, thereby an angle is also arranged between stratum main stress bar and borehole axis, may be defined as ' main to ' and ' leading role ' (see figure 1).Yet in existing perforating gun, the directive of perforating bullet is all vertical with rifle, so present oriented perforation has been a directive ' main to ' projecting direction on horizontal plane, the centre is differing from an angle, and this angle is exactly ' leading role '.This tangible inadequately reason place of just present oriented perforation effect of increasing production.
The utility model content
The technical problems to be solved in the utility model is, for the oriented perforation rifle provides a kind of angle modulation firing mount that can adjust the firing angle of perforating bullet.
For solving the problems of the technologies described above, the accent firing angle firing mount that the utility model provides comprises the firing mount pipe, the bullet cover, bushing member and jackscrew, have the hole group identical on the firing mount pipe tube wall vertically with perforating bullet quantity, each Kong Zuzhong contains two square holes, two angle modulation holes and two tapping holes, first square hole is greater than second square hole, the line of centres of two square holes, the axis of the line of centres in two angle modulation holes and firing mount pipe is vertical mutually and crossing, two tapping holes are corresponding respectively between two the angle modulation holes and second square hole, and first square hole of adjacent two Kong Zuzhong differs 180 ° on the orientation; Described bullet cover middle part is provided with the cylindrical protrusion of two radial symmetric; The upper surface of described bushing member is to be provided with central shaft hole between arc surface and the upper and lower end face, and the diameter of central shaft hole and the diameter of described cylindrical protrusion are complementary, and the quantity of bushing member is the twice of perforating bullet quantity; Perforating bullet is placed in the described bullet cover, two cylindrical protrusion of bullet cover are respectively overlapped a described bushing member, every pair of bushing member and described firing mount pipe are connected, the arc surface of bushing member contact with the firing mount inside pipe wall and two central shaft holes and two angle modulation holes one by one over against, the perforation of described perforating bullet is rectified described first square hole, and projectile tail is rectified described second square hole; When assembling during perforating gun, rotate after cylindrical protrusion that bullet puts makes the axis of perforating bullet adjust to the firing angle direction with the angle modulation instrument, described jackscrew is screwed in the described tapping hole and with described bullet overlap dieback.
According to the utility model, the opening of described first square hole satisfies perforating bullet and rotates 40 ° of jets that do not block perforating bullet by horizontal level around central shaft hole.
According to the utility model, described bullet cover and described bushing member all adopt the polyethylene material of anti-150 ℃～200 ℃ of high temperature or nylon material to make.
The utility model is provided with two cylindrical protrusion by the radial symmetric that puts at each bullet, be equipped with the bushing member that is connected with the firing mount pipe and the angle modulation hole on the firing mount pipe again, like this, when assembling oriented perforation rifle, can be by corresponding instrument from angle modulation hole rotary cylinder projection, thereby perforating bullet is rotated, relative to the firing mount pipe until the axis of perforating bullet being adjusted to the firing angle direction and bullet being overlapped dieback with jackscrew.Adopted perforating gun of the present utility model, the perforation direction of its perforating bullet is consistent with the principal direction of stress of gas-bearing formation, therefore, not only penetration depth is big for the perforating bullet that penetrates by this direction, and can link up nearly borehole axis area optimum oil circulation road and reach the good result of volume increase.
