Abstract
The invention discloses a multi-section sliding sleeve type sand jet perforating and fracturing tool. The multi-section sliding sleeve type sand jet perforating and fracturing tool comprises one or more fracturing tool sections connected with an oil pipe, wherein each fracturing tool section comprises a gun body; the upper end and the lower end of the gun body are respectively connected with an upper connector and a sliding sleeve work barrel; a nozzle is formed in the gun body; a sliding sleeve which is fixed in the gun body through a shear pin and blocks the nozzle is arranged at a part of the gun body, which is provided with the nozzle; a ball body which pushes the sliding sleeve by an external force and closes an inner hole of the sliding sleeve is arranged at the rear end of the sliding sleeve; a lock ring is arranged on the periphery of the sliding sleeve; and a step structure which is matched with the lock ring and blocks the sliding sleeve to slide out is arranged on the inner wall of the sliding sleeve work barrel. The multi-section sliding sleeve type sand jet perforating and fracturing tool is reasonable in structure, is a novel well stimulation integrating perforating, fracturing and isolating, is wide in range of application, is particularly suitable for later stimulation and medium and low penetration layers of a large displacement well, a long horizontal well and an old well, and is simple in operation, low in risk and low in cost.
Description
Technical field
The present invention relates to a kind of abrasive perforating fracturing tool.
Background technology
The most frequently used sleeve pipe or tail pipe perforation completion mode is both at home and abroad at present: pressure break behind the first perforation, but to extended reach well, long horizontal well, the especially raising the output in oil gas well later stage; In, the less permeable layer fracturing reform has tangible limitation; Difficulty of construction is big, and risk is high, and construction cost is also high.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the simple multistage sleeve type of construction technology abrasive perforating fracturing tool.
Technical solution of the present invention is:
A kind of multistage sleeve type abrasive perforating fracturing tool is characterized in that: one ~ a plurality of fracturing tool sections that are connected with oil pipe are arranged; Each fracturing tool section comprises the rifle body; The upper and lower side of rifle body is connected with top connection, sliding sleeve seating nipple respectively, on the rifle body, is provided with nozzle, is provided with the position of nozzle at the rifle body; The sliding sleeve that setting is fixed in the rifle body through shear pin and nozzle is stopped; The rear end of sliding sleeve is provided with and relies on outer force urges sliding sleeve, with the spheroid of bore closure in the sliding sleeve, in the sliding sleeve periphery lock ring is set, on sliding sleeve seating nipple inwall, be provided with the ledge structure that cooperates, stops sliding sleeve to deviate from said lock ring.
Nozzle is contained in the sheath.
Sliding sleeve upper end inwall is ramped shaped ball seat form.
Nozzle radially evenly distributes along the rifle body diameter.
Sliding sleeve aperture in each fracturing tool section and the diameter of spheroid are different, and the sphere diameter of fracturing tool section that is arranged in the bottom is less than the aperture of the fracturing tool section sliding sleeve of adjacent upper.
The present invention is rational in infrastructure, is beam hole, pressure break, the incorporate novel well stimulation of isolation, utilizes the injection of a band nozzle to penetrate sleeve pipe, rock according to producing high-velocity fluid; And in the stratum, form hole; The duct promotes annular pressure when forming supercharging under the high-pressure water jet effect, and moment presses off the stratum when the hole internal pressure surpasses formation fracture pressure, realizes the jetting pressure break; High-velocity fluid subsequently directly acts on the hole bottom; Generation is higher than the pressure of formation fracture pressure, in the stratum, produces a rule crack, forms gas channel.Wide adaptability of the present invention, the later stage that is particularly useful for extended reach well, long horizontal well, old well is increased production and middle less permeable layer, and operation is simple, risk is low, and cost is also low.
The present invention can be used for the well cementation, do not cement the well and open hole well in; Can be connected with fixed tubular column or continuous tubing string; By the pressure break arts demand can with realize multistage fracturing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
A kind of multistage sleeve type abrasive perforating fracturing tool has one ~ a plurality of fracturing tool sections that are connected with oil pipe; Each fracturing tool section comprises rifle body 8; The upper and lower side of rifle body is connected with top connection 1, sliding sleeve seating nipple 9 respectively, on the rifle body, is provided with nozzle 3, is provided with the position of nozzle at the rifle body; The sliding sleeve 5 that setting is fixed in the rifle body through shear pin 6 and nozzle is stopped; The rear end of sliding sleeve is provided with and relies on outer force urges sliding sleeve, with the spheroid 2 of bore closure in the sliding sleeve, in the sliding sleeve periphery lock ring is set, on sliding sleeve seating nipple inwall, be provided with the ledge structure that cooperates, stops sliding sleeve to deviate from said lock ring 7.Nozzle is contained in the sheath 4.Sliding sleeve upper end inwall is ramped shaped ball seat form.Nozzle radially evenly distributes along the rifle body diameter.
Sliding sleeve aperture in each fracturing tool section and the diameter of spheroid are different, and the sphere diameter of fracturing tool section that is arranged in the bottom is less than the aperture of the fracturing tool section sliding sleeve of adjacent upper.
During construction operation, sliding sleeve 5 is closed nozzle 3, keeps tubing string unobstructed, can carry out operations such as mud perfusion; During spraying operation, drop into ball 2 earlier, ball 2 drops on the ball seat of sliding sleeve 5, closes the sliding sleeve endoporus, promptly closes the tubing string passage, and under the fluid power effect, sliding sleeve 5 is cut off shear pin 6, promotes ball 2 simultaneously, and sliding sleeve 5 together moves down with lock ring 7; At this moment, assurance nozzle 3 passages are opened fully, under the fluid power effect, form and spray, and injection is carried out pressure break after accomplishing, thereby completion is sprayed, fracturing work.Nozzle 3 carries out the high pressure sealing formula with the rifle body and is connected.
