Description
Technical field
The present invention relates to the untraditional reservoir Well Completion Engineering of Oil Reservoirs such as oil, natural gas field, especially a kind of underground fracture is used
The intelligent bridging plug of pumping makees completion method with perforation connection.
Background technology
Exploitation and the continuous exhaustion of the energy with oil gas field, unconventionaloil pool is by as the following petroleum gas energy
Important reliever relay.Statistics shows that the unconventional gas resource total amount such as China's compact sandstone gas, shale gas, coal bed gas is
The several times of conventional gas stock number, Unconventional gas exploration-development potential is unlimited.Unconventionaloil pool reservoir is respectively provided with reservoir
Fine and close, low hole, the feature of hyposmosis.At this stage, for the exploitation of this kind of untraditional reservoir, pumping bridging plug joins what is made with perforation
Completion technique has the advantages that the cycle is short because of it, performance it is good be the reservoir fracturing important method.But the method is existed simultaneously
Following deficiency：1. bridging plug can not be reused, it is both needed to consume a bridging plug using each layer of bridging plug pressure break, increase is constructed into
This；2. needing to bore after the completion of pressure break except bridging plug setting in pit shaft, extend the activity duration, increase operating risk.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of intelligent bridging plug of pumping and make completion method with perforation connection, solve
Certainly existing pumping bridging plug, which has bridging plug, can not reuse, need to bore except complex jobs such as bridging plugs, realize bridging plug in fracturing process
Recycling, pit shaft full-bore is kept after the completion of pressure break, exempts the purpose for boring plug program.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：The intelligent bridging plug of one kind pumping joins with perforation
Make completion method, comprise the following steps：
(1) in bunch tube preset short sleeve to mark each fractured interval position, tripping in cable, magnetic orientator,
Perforation casing string, the preset sleeve pipe position of the first interval is detected by magnetic orientator, starts perforating gun perforation, acts cable tube
String, completes the pressure break of the first interval；
(2) tripping in cable, magnetic orientator, perforating gun, intelligent bridging plug pipe string after the completion of first paragraph pressure break, true by magnetic orientator
Fixed second fractured layer position, starts perforating gun perforation, and setting bridging plug carries out unsealing bridging plug after the completion of pressure break, pressure break, rises
Cable fracturing string, perforation shotgun is filled up, tripping in cable, magnetic orientator, perforating gun, intelligent bridging plug pipe string, by magnetic orientation
Instrument determines the 3rd fractured layer position, starts perforating gun perforation, and setting bridging plug carries out unsealing bridging plug after the completion of pressure break, pressure break；
(3) above step is repeated, full wellbore fracture is completed.
The beneficial effects of the invention are as follows：
1st, intelligent bridging plug can be reused, and without reserving a bridging plug for each interval, greatly save instrument application
Cost；
2nd, pit shaft keeps full-bore after the completion of pressure break, remove from it is conventional bore plug program, reduce task difficulty, save operation into
This, improves operating efficiency, facility is provided for subsequent job.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description：
The intelligent bridging plug of the pumping of the present invention makees completion method with perforation connection, comprises the following steps：
(1) in bunch tube preset short sleeve to mark each fractured interval position, tripping in cable, magnetic orientator,
Perforation casing string, the preset sleeve pipe position of the first interval is detected by magnetic orientator, starts perforating gun perforation, acts cable tube
String, completes the pressure break of the first interval；
(2) tripping in cable, magnetic orientator, perforating gun, intelligent bridging plug pipe string after the completion of first paragraph pressure break, true by magnetic orientator
Fixed second fractured layer position, starts perforating gun perforation, and setting bridging plug carries out unsealing bridging plug after the completion of pressure break, pressure break, rises
Cable fracturing string, perforation shotgun is filled up, tripping in cable, magnetic orientator, perforating gun, intelligent bridging plug pipe string, by magnetic orientation
Instrument determines the 3rd fractured layer position, starts perforating gun perforation, and setting bridging plug carries out unsealing bridging plug after the completion of pressure break, pressure break；
(3) above step is repeated, full wellbore fracture is completed.
Below in conjunction with the accompanying drawings, the present invention is described in further details.
As shown in figure 1, first, according to design fractured interval position, each design fractured interval is preset short in bunch tube
Sleeve pipe 1, coiled tubing 2, mechanical positioners 3, the coiled tubing pipe string tripping in pit shaft of perforating gun 4 are examined using mechanical positioners 3
The position of the first fractured interval short sleeve 1 is surveyed, determines that start coiled tubing behind the position of the first fractured interval is carried out with perforating gun 4
Coiled tubing perforation pipe string is played out after the completion of perforation, perforation, pressurization pressure break is carried out, first paragraph pressure break is completed, 5 be preforation tunnel.
As shown in Fig. 2 secondly, after the completion of first paragraph pressure break, pumping tripping in cable 6, magnetic orientator 7, perforating gun 8, intelligence
The pipe string of bridging plug 9, when magnetic orientator detects the second fractured interval short sleeve position, opens perforating gun perforation, after the completion of perforation
Setting learning bridge unseals intelligent bridging plug after the completion of filling in row the second fractured interval pressure break, second segment pressure break, acts cable pressure break pipe
String, loads the follow-up continuous tripping in cable fracturing string of perforation shotgun, when magnetic orientator detects the 3rd fractured interval short sleeve position
When putting, setting learning bridge fills in the fractured interval pressure break of row the 3rd after the completion of opening perforating gun perforation, perforation, and the 3rd section of pressure break is completed
Intelligent bridging plug is unsealed afterwards, acts cable fracturing string, and more than the 3rd section can be carried out not by repeating second and third interval fracturing process above
Fractured interval operation.
As shown in figure 3, it is last, after the completion of the equal pressure break of all intervals, act fracturing string, the pressure break for completing full pit shaft is applied
Work, 10 stitch for pressure break.
In summary, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can
Can propose other embodiments easily within the technological guidance's thought of the present invention, but this embodiment is included in this hair
Within the scope of bright.
