Abstract
A vacuum negative pressure perforation device belongs to the technical field of oil field oil-gas well perforation and is characterized in that negative pressure difference is rapidly formed between a shaft and a stratum, and the flow conductivity of a perforation channel is improved. The vacuum negative pressure perforation device aims to solve the technical problem that the negative pressure difference can not be rapidly formed in an existing perforation technology. According to the technical scheme which solves the technical problem, in the whole device, a vacuum pump is used for absorbing vacuum of a vacuum perforation gun through the tail of a dynamic negative pressure perforation vacuum gun, reading vacuum degree representation numbers and judging whether the vacuum perforation gun is vacuumized. When the pressure in the vacuum perforation gun reaches a preset number, a sealing connector is moved downwards to seal the tail of the dynamic negative pressure perforation vacuum gun, so that a vacuum state is maintained in the vacuum perforation gun. The vacuum negative pressure perforation device has the advantages of being capable of effectively flushing the perforation channel, improving the flow conductivity of the perforation channel, effectively relieving perforation pollution, lowering the skin factor and improving single well productivity.
Description
Technical field
The utility model belongs to oil and gas wells in oil fields perforating technology field, specifically a kind of negative pressure of vacuum perforating system.
Background technology
At present, known oil gas well is in the perforation process, can not form Negative Pressure Difference fast at pit shaft and ground interlayer during the routine underbalance perforating, liquid is produced fast to flow, thereby the clean-up performance to the perforation tunnel is difficult to get a desired effect, and then can not well wash the perforation tunnel, influence the flow conductivity of perforation tunnel.
Summary of the invention
Can't make pit shaft and ground interlayer form Negative Pressure Difference fast in order to overcome existing perforating technology, liquid be produced fast flow, the utility model provides a kind of negative pressure of vacuum perforating system, has effectively washed the perforation tunnel, has strengthened the flow conductivity of perforation tunnel.The technical scheme in the invention for solving the technical problem is: a kind of negative pressure of vacuum perforating system is connected with comprising that vacuum pump is held one by one with plastic flexible pipe, the two ends of special threeway are connected with plastic flexible pipe two with plastic flexible pipe one respectively, connect vacuum meter in the middle of the special threeway, emptying joint one end is connected with plastic flexible pipe two, one end is connected with dynamic negative-pressure perforation vacuum gun breech thread seal with emptying joint sealing cushion rubber, described dynamic negative-pressure perforation vacuum gun breech, dynamic negative-pressure perforation vacuum gun breech O-ring seal is connected with vacuum perforating gun thread seal, after being evacuated, the seal nipple that moves about moves down, seal up dynamic negative-pressure vacuum perforation gun breech with the big O-ring seal of the seal nipple that moves about and the little O-ring seal of seal nipple that moves about, keep vacuum in the vacuum perforating gun thereby make.
The beneficial effects of the utility model are: this device can effectively wash the perforation tunnel, strengthens the flow conductivity of perforation tunnel, has effectively removed the perforation pollution, reduces skin factor, improves single well productivity.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
