Detailed description of the invention
Following content is the further very thin explanation done the present invention in conjunction with concrete preferred embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For the those of ordinary skill of technical field of the present invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, said structure all should belong to protection scope of the present invention.
The overall structure of hydraulic power pulse device provided by the present invention as shown in Figure 1, at least comprise head and afterbody, wherein head at least comprises housing 1, flange 2 and short tube 3, described housing 1 is provided with through hole A4, through hole A4 place is provided with resilient sleeve 5, and described resilient sleeve 5 is arranged on by clip 6 on the outer wall of housing 1, and flange 2 is positioned at the bottom of housing 1, described flange 2 contacts with the inwall of housing 1, and the position that flange 2 contacts with housing 1 inwall is provided with seal 19.The bottom of described housing 1 is provided with nut 17 and pad 18, flange 2 and housing 1 is fixed by nut 17 and pad 18.
Short tube 3 is installed on the inside of housing 1, and forms chamber A7 between short tube 3 and housing 1, and through hole A4 is communicated with chamber A7; The bottom of short tube 3 is connected with flange 2, and housing 1 and flange 2 are equipped with through hole B8, and the internal chamber of short tube 3 is in communication with the outside by through hole B8.
Described afterbody at least comprises outer cover 9 and connector 10, wherein outer cover 9 cylindrically, connector 10 is fixed on the top of outer cover 9, interior pipe 11 is provided with in outer cover 9 and connector 10, outer cover 9 and connector 10 are enclosed within interior pipe 11 and also can slide on interior pipe 11, and connector 10 contacts with interior pipe 11, and the position that connector 10 contacts with interior pipe 11 is provided with sealing ring 12, define a chamber B13 between the outer wall of interior pipe 11 and outer cover 9, chamber B13 is communicated with chamber A7.
The bottom of described interior pipe 11 and the top of short tube 3 are fixedly connected, and are interconnected between the two, are connected between interior pipe 11 and short tube 3 by key 20, and the tube wall of interior pipe 11 is provided with through hole C14, and the position that key 20 connects is positioned at the below of through hole C14.Described through hole C14 is communicated with chamber B13, and the inside of described interior pipe 11 is provided with pipe box 21, and described pipe box 21 is positioned at the top of key 20, and is positioned at through hole C14 place, is closed by through hole C14, and described pipe box 21 is provided with ball valve orifice, for placing ball valve 22.The top cover of interior pipe 11 has spring 15, and the bottom of spring 15 withstands on connector 10, and the top of spring 15 is blocked on the locating snap ring 16 that interior pipe 11 outer wall is provided with.
Hydraulic power pulse device provided by the present invention utilizes reason position, drill string lower going-into-well bottom.When needs are to shaft bottom supply working media, cast ball valve, because ball valve has stopped the flowing of liquid, therefore the pressure that pipe box is subject to constantly increases, and when increasing to a certain degree, is cut off by key, then working media is by there being the drill string of flushing liquor, along interior pipe and short tube, finally sprayed by through hole B, form hydraulic blow.Meanwhile, another strand of working media enters chamber B and chamber A through the through hole C of interior pipe.Because working media is at the end of one's rope after entering chamber A, so the pressure in chamber A starts to increase.Now, resilient sleeve starts to expand.When pressure continues to be increased to spring given pressure, it is a little that its pressure forces afterbody to retreat by outer cover and connector Compress Spring, now outer cover and housing are separated, and the working media being arranged in chamber A and chamber B is tried hard to the flowing of the pipe external space, and now resilient sleeve tries hard to reposition.Make chamber A and chamber B pressure sharply land because working media freely flows out, afterbody almost returns in impact type under the action of the spring, with body contact, causes chamber A and chamber B to form sealing.The a little displacement of now head and the afterbody associating in resilient sleeve, makes to produce hydraulic blow in the working portion of head.In the chamber A that hydraulic blow produces, the increase of pressure, forces resilient sleeve sharply to expand by through hole A, reopens resilient sleeve and presses to the borehole wall, thus make working media enter working position.Head and afterbody are after resilient sleeve top offset, and then reposition, head is parked in flange bottom rapidly.Circulate according to this, thus produce hydraulic blow and waterpower pulse in shaft bottom, filtration tubing string and producing zone are had an effect.Inorganic agent can reduce to be arranged in and filters tubing string and reduce the bonding strength silted up of tar productivity, and the waterpower pulse that this device produces can destroy this and silts up, creates advantage for improving well recovery rate.So, like this oil productivity that alternating pressure can improve oil-gas Layer is produced to oil reservoir.
For automatic oscillating characteristics such as the impulsive forces that pulse frequency and generation are vibrated, belong to the scope of pulse evaluation.This is carried out to the feasibility of simple computation and susceptible of proof project organization.
The frequency of elastic oscillation is the function of elastic component (spring) characteristic and oscillating member quality.Length is the afterbody (together with being full of the cavity of working media interior) of about 200mm, and its quality is about 0.2kg.Facilitate to work and facilitate in order to this device starts, the reasonable pressure of flushing liquor reduces to 5 ~ 10dN/cm
2left and right.So consider the cross sectional area of afterbody, cut the area of pipe feed fluid, the power needed for tail springs is 100 ~ 200dN.
So the frequency calculated according to known formula is: W=√ K/m ≈ 20 ~ 30Hz.
