Abstract
The utility model relates to a novel hydraulic jetter for oil industry which can achieve hydraulic perforation and also can realize hydraulic fracturing , including a main body (1), a cap (2), and a nozzle (3). The nozzle (3) is fixed to the main body (1) through the cap (2), the aperture of the nozzle is Phi5-Phi8mm, which satisfies the request of hydraulic perforation and also ensures the designed flow of hydraulic fracturing; for vertical wells, horizontal wells, and slant wells or casing pipes of Phi139.70mm, Phi177.80mm, open hole completion well, perforation and hydraulic fracturing construction can both be carried out in one reservoir or several reservoirs. By replacing and blocking of the nozzles distributed on the novel hydraulic jetter, the requests for diversified perforation size and quantity, hydraulic fracturing construction ejecting quantity, formation-parting pressure for different well.
Description
Technical field
The utility model relates to that petroleum industry uses not only can finish hydraulic perforation but also can realize the novel hydropower ejector of fracturing, is applicable to perforating oil gas well, the fracturing reform technology of multiple completion mode.
Background technology
Hydraulic perforation is at interval of interest, by containing the sand high pressure liquid stream, pierces through sleeve pipe and stratum, forms than deep holes, presses off the breach of oil-gas Layer when becoming pressure break.For realizing that the hydraulic ejector that hydraulic perforation designs has varied, spiral spray device, sliding sleeve ejector, monoplane ejector, extension type hydraulic ejector etc. are arranged, these hydraulic ejectors carry out hydraulic perforation only, can not further implement fracturing, it is φ 3～φ 5mm that its nozzle generally designs the aperture, and function of use is single.After adopting these hydraulic ejectors that perforating oil gas well is finished, must trip out tubing string, be lowered to fracturing down-hole assorted column jacket again, implement fracturing.When carrying out perforation and pressure break, need repeatedly play lower tubular column, long construction period, less economical.
Summary of the invention
The purpose of this utility model is to provide a kind of novel hydropower ejector, can be and realize perforation, fracturing integrated, both satisfied the requirement of hydraulic perforation, guaranteed the fracturing design again, perforation and pressure break only need remove one-trip string, simplify working procedure, reduced the oil-gas field development cost.
The utility model is achieved in that and comprises main body 1, pressure cap 2, nozzle 3, and nozzle 3 is fixed on the main body 1 by pressure cap 2.
The utility model also adopts following technical scheme:
Nozzle 3 apertures are φ 5～φ 8mm.
Advantage of the present utility model is: 1, the nozzle bore of novel hydropower ejector is φ 5～φ 8mm, has both satisfied the requirement of hydraulic perforation, has guaranteed fracturing design discharge capacity again; 2, novel hydropower ejector, for the well of straight well, horizontal well, inclined shaft or φ 139.70mm, φ 177.80mm size sleeve pipe, barefoot completion, single or multiple lift all can carry out perforation, pressing crack construction; 3, by the nozzle that distributes on the novel hydropower ejector is changed, shutoff, can satisfy different wells to perforation diameter and quantity, pressing crack construction discharge capacity, formation fracture pressure requirement.
Description of drawings
Fig. 1 is a novel hydropower emitter construction schematic diagram;
Fig. 2 is hydraulic perforation and fracturing integrated process pipe string schematic diagram based on the novel hydropower ejector.
The specific embodiment
As shown in Figure 1: the novel hydropower ejector mainly is made up of main body (1), pressure cap (2), nozzle (3), and main body 1 two ends are tubing thread, can be connected with oil pipe, the novel hydropower ejector is lowered to perforation, the pressure break degree of depth of oil gas well design by oil pipe; Pressure cap 2 is that nozzle 3 is fixed on the main body 1; Nozzle 3 is vital parts of novel hydropower ejector, its design of structural size is to realize the main factor of the success or failure of hydraulic perforation, pressure break, the jet size one of jetting will satisfy the rate request of hydraulic perforation, will satisfy the circulation requirement of load fluid in the pressing crack construction simultaneously.Though less nozzle bore can satisfy the technical requirements of quick perforation, for hydraulic perforation and fracturing integrated technology, the time of perforation is relatively short, and the circulation requirement of load fluid in the later stage pressing crack construction is mainly considered in the aperture of nozzle.Under the situation that satisfies the perforation requirement, the factor of discharge capacity and sand ratio prevents situations such as overhigh pumping pressure, sand plug in more will considering to construct during designs of nozzles, so, general bigger than normal being advisable of nozzle bore, it is φ 5～φ 8mm that its nozzle generally designs the aperture.
As shown in Figure 2: hydraulic perforation and fracturing integrated process pipe string (from top to bottom) based on the novel hydropower ejector mainly are made up of oil pipe 4, universal joint 5, eccentric locater 6, novel hydropower ejector 7, ball-and-seat 8, screen casing 9, plug 10.Oil pipe 4, universal joint 5, eccentric locater 6, novel hydropower ejector 7, ball-and-seat 8, screen casing 9, plug 10 connect successively, and wherein universal joint 5 and plug 10 effects are that process pipe string is entered in horizontal well, the inclined shaft easily; The direction of eccentric locater 6 adjustable renewing type hydraulic ejectors 7; Ball-and-seat 8 effects are that fracturing fluid enters the reservoir that needs fracturing reform when guaranteeing perforation, pressure break with certain pressure, direction.
The utility model presses off reservoir by two steps.The first step: hydraulic ejector is carried out jetting over against oil gas well design perforated interval, form one (or a plurality of) in oil-gas Layer and spray the duct; Second step: after the duct forms, fracturing fluid is injected duct by injector nozzle with very high speed through oil pipe, the oil jacket annular space also injects certain liquid to improve bottom pressure by designing simultaneously, make the stratum produce the crack and begin and extend towards the depths, thereby realization is to effective transformation of oil gas well.
When being lowered to above-mentioned process pipe string, this novel hydropower ejector is down to needs perforation position.After tubing string puts in place, at first adopt flushing fluid float amount well-flushing, to importing and exporting the water quality unanimity.Inject perforating fluid from oil pipe, implement the hydraulic perforation operation, discharge capacity and well head pressure are determined by nozzle quantity, aperture and nozzle and the sleeve pipe distance of hydraulic ejector.During perforation, perforating fluid injects from oil pipe, is returned out by oil, cover annular space.Then, by the discharge capacity of designing requirement, inject fracturing fluid from oil pipe, simultaneously, inject original gelatin from the oil jacket annular space and carry out pressing crack construction, in order to satisfy required discharge capacity of pressure break and the requirement of reservoir fracture pressure, it is 1/3～1/2 of oil pipe injection discharge capacity that the oil jacket annular space injects discharge capacity.After the bottom pressure break is finished, anti-circulation kill-job, if confirm that injector performance is intact, behind the upper lifting pipe post, can continue hydraulic perforation and pressure break top interval by above-mentioned operation, after whole interval pressure break is finished, trip out hydraulic perforation and fracturing integrated process pipe string, be lowered to completion tubular column, product is asked in discharge opeing.
