Abstract

The present invention relates to oil extraction in oil field field of engineering technology, belong to a kind of drive suitable for pressure and use intelligent fracturing sliding bush.The present invention solves in fracturing string, and well temperature, flow, sand amount and pressure can only be confined to ground survey, the low problem of accuracy rate.The present invention is made of central tube (1), sand control bushing (2), spring (3), integrated sensor (4), pressure gauge (5), adjusting ring (6), anti-rotation pin (7), big spring (8), valve (9), valve seat (10), sliding sleeve (11), cutting pin (12) and lower contact (13)；Wherein sand control bushing (2), spring (3), integrated sensor (4) and pressure gauge (5) are fixed in central tube (1), and adjusting ring (6), big spring (8), valve (9), valve seat (10), lower contact (13) are sequentially sleeved in central tube (1) outside.The advantages that present invention has the pressure drive time short, and tubing string is stablized, at low cost, realizes effective exploitation.

Description

One kind being suitable for pressure and drives with intelligent fracturing sliding bush
Technical field
The present invention relates to oil extraction in oil field field of engineering technology, the one kind for belonging to the intelligent pressing crack construction for oil gas water well is suitable It drives for pressing with intelligent fracturing sliding bush.
Background technique
In the fracturing string applied at present, well temperature, flow, sand amount and pressure can only be confined to ground survey, quasi- True rate is low, thus pressing crack construction low efficiency, success rate is low, has developed pressure thus and drives with intelligent fracturing sliding bush.
Summary of the invention
The purpose of the present invention is realize tubing string can directly measure the one of well temperature, flow, sand amount and pressure in well Kind is suitable for pressure and drives with intelligence fracturing sliding bush.
The present invention it is main it by central tube, sand control bushing, spring, integrated sensor, pressure gauge, adjust ring, anti-rotation pin, Big spring, valve seat, sliding sleeve, cuts pin and lower contact composition at valve；Wherein sand control bushing, spring, integrated sensor and pressure Power meter is fixed in central tube, adjusts ring, big spring, valve, valve seat, lower contact are sequentially sleeved in outside central tube, adjust ring with Central tube is fixedly connected by anti-rotation pin, and lower contact and central tube screwed connection slide over and pass through break pin inside central tube Nail is connect with central tube.
Valve seat and integrated sensor and pressure gauge integrated design.
Valve, valve seat design have the function of anti-backwash
Compared with the prior art the present invention has the advantages that
The configuration of the present invention is simple is reasonable, by valve seat and integrated sensor and pressure gauge integrated design, in pressing crack construction can and When detection subsurface temperature, pressure break, the overall situation of operational discharge capacity and sand feeding amount, instruct subsequent pressing crack construction, and during adding sand The design of valve, valve seat tool has the function of anti-backwash, and integrated sensor and pressure gauge is protected not to be denuded,
Detailed description of the invention: Fig. 1 is the structural diagram of the invention.
Specific embodiment: the invention will be further described with reference to the accompanying drawing: it by central tube 1, sand control bushing 2, Spring 3, pressure gauge 5, adjusts ring 6, anti-rotation pin 7, big spring 8, valve 9, valve seat 10, sliding sleeve 11, cuts integrated sensor 4 Disconnected pin 12 and lower contact 13 form；Wherein sand control bushing 2, spring 3, integrated sensor 4 and pressure gauge 5 are fixed on central tube 1 Interior, adjusting ring 6, big spring 8, valve 9, valve seat 10, lower contact 13 are sequentially sleeved in outside central tube 1, adjust ring 6 and central tube 1 It is fixedly connected by anti-rotation pin 7, lower contact 13 and 1 screwed connection of central tube, sliding sleeve 11 pass through break pin inside central tube 1 Nail 12 is connect with central tube 1.
Valve seat 10 and 5 integrated design of integrated sensor 4 and pressure gauge.
Valve 9, the design of valve seat 10 have the function of anti-backwash.
Scene is in use, 1 top of central tube and 13 lower part of lower contact of the present invention are separately connected packer.By integrated sensor 4, pressure gauge 5 is fixed in central tube 1.It in fracturing process, is suppressed in oil pipe, after liquid enters from hole 14, hole 15, integrates and pass Sensor 4, pressure gauge 5 can measure temperature and overpressure respectively, after liquid enters from hole 16, hole 17, integrated sensor 4, pressure Power meter 5 can measure flow, sand amount and the outer annular pressure of pipe respectively.After reaching certain pressure, pin 12 will be cut and cut, sliding sleeve 11 move down, 18 feed liquor of sand jet outlet, and compression big spring 8 carries out sandblasting.Tubing string is proposed into well head after pressure, take out integrated sensor 4 and Pressure gauge 5 carries out playback and reads the construction datas such as temperature, flow, sand amount and pressure, realizes that pressure drives well intelligence construction.
