Abstract
The invention discloses a bridge type separate mining device suitable for multilayer separate mining, which is designed for separate mining without being limited by yield and realizing separate mining of two or more oil layers. The lower part of the upper joint of the bridge type separate mining device is connected with a lower joint sealed by an axial sealing ring; the outer wall of the middle part of the lower joint is connected with a filtering sleeve provided with a flow passing hole, the upper part of the lower joint is provided with a central single-flow channel communicated with the flow passing hole of the filtering sleeve, and a bridging hole which is not communicated with the central single-flow channel is uniformly distributed in the cylinder wall of the lower joint; the top end of the central single-flow channel is connected with a ball seat main body, a ball seat sealed by a sealing ring is arranged on the inner step of the ball seat main body, a steel ball centralizer and a steel ball are arranged above the ball seat, and the top end of the ball seat main body is connected with a steel ball shield. The bridge type separate mining device is matched with the packer to perform separate mining of two or more oil layers without being limited by yield.
Description
Technical field
The present invention relates to a kind of bridge-type being applicable to multilayer separate zone production to divide and adopt device, belong to multiple zone production technique field.
Background technology
At present, oil field at home layering oil production technology is mainly based on separate extracting pump oil production by layer, its general principle is with packer sealing oil jacket annular space, separates upper and lower payzone, draws up layer with pump on separate extracting pump, Xia Bengchou lower floor, LAYER FLUID enters in pump through respective passage respectively, then discharges pump barrel, and two cover oil pumping systems are to oil reservoir pumping lifting respectively, can interlayer interference be avoided, improve oil well output.
But this oil production by layer mode can by the restriction in separate extracting pump pump footpath.Although current most small pump diameter is the pump footpath that Φ 38/32(discharge capacity is equivalent to Φ 38), for stripper field, pump footpath is still bigger than normal, causes pump efficiency lower.In addition, this oil production method is only applicable to two-layer separate zone production, cannot realize two-layer above separate zone production.
Summary of the invention
The object of the present invention is to provide a kind of bridge-type being applicable to multilayer separate zone production to divide and adopt device, to make point to adopt by production restriction, realize adopting dividing of two-layer or two-layer above oil reservoir.
Concrete technology contents of the present invention is as follows:
This bridge-type divides the top connection bottom connection of adopting device to seal lower contact by axial sealing ring; In the middle part of lower contact, outer wall is connected with the overanxious cover of flowing hole, and lower contact top is provided with the center single flow channel being communicated with overanxious cover flowing hole, is evenly equipped with the bridge opening excessively not being communicated with center single flow channel in lower contact barrel; Single flow channel top, center connects ball seat main body, and in ball seat main body, step is provided with the ball seat sealed by sealing ring, is provided with steel ball stabilizer and steel ball above ball seat, and ball seat main body top connects steel ball guard shield.
This bridge-type is divided and is adopted device and packer mating reaction, can not be subject to production restriction, complete the separate zone production of two-layer or two-layer above oil reservoir.
Accompanying drawing explanation
Fig. 1 is that the bridge-type being applicable to multilayer separate zone production is divided and adopted device structural representation.
Detailed description of the invention
Embodiment:
With reference to Fig. 1, embodiments of the invention are further illustrated:
This bridge-type is divided and is adopted device and mainly comprise top connection 1, steel ball guard shield 2, ball seat main body 3, steel ball stabilizer 4, steel ball 5, ball seat sealing ring 6, ball seat 7, axial sealing ring 9, overanxious cover 10 and lower contact 11;
The connection of top connection 1 lower internal thread seals lower contact 11 by axial sealing ring 9.In the middle part of lower contact 11, outer wall is connected with the overanxious cover 10 of flowing hole, and lower contact 11 top is provided with the center single flow channel 12 being communicated with overanxious cover 10 flowing hole, is evenly equipped with the bridge opening 8 not excessively being communicated with center single flow channel 12 in lower contact 11 barrel.Center single flow channel 12 top is threaded ball seat main body 3, and in ball seat main body 3, step is provided with the ball seat 7 sealed by sealing ring 6, is provided with steel ball stabilizer 4 and steel ball 5 above ball seat 7, and ball seat main body 3 top internal thread connects steel ball guard shield 2.
Before onsite application, selecting oil well pump according to oil well liquid measure, determining that one's duty adopts device quantity according to point adopting the number of plies, the corresponding bridge-type of one deck is divided and is adopted device and a packer, then, bridge-type is divided the upper and lower joint adopting device connected pipes respectively, lower to precalculated position by design.During work, this bridge-type is divided and is adopted device and coordinate packer effect, and lower floor's fluid enters oil pipe through bridge opening 8, and top fluid enters oil pipe through center single flow channel 12, and LAYER FLUID does not interfere with each other.Steel ball 5 forms ball-and-seat, can prevent inter-layer fluid from pouring in down a chimney.
