Description
Technical field
The utility model relates to the equipment of a kind of oil, natural gas exploration and mining operations, relates in particular to the perforating bullet of a kind of oil gas well with the close deep penetration perforator in high hole.
Background technology
In oil, natural gas exploration and mining operations, usually finish the process from the drilling well to the perforation completion in the following order: drilling well on the oil-containing block → sleeve pipe is put into well → with the annular space between concrete spouting sleeve pipe and the well (fixed sleeving) → perforating bullet is contained under the perforating gun to the oil-gas Layer position → jet that perforating bullet → perforating bullet of the calibration degree of depth → ignition perforating gun is exported penetrates sleeve pipe and layer of concrete successively, enter in the oil-gas Layer, between pit shaft and oil-gas Layer, form gas channel → oil gas and enter pit shaft by these passages.
At the initial stage of adopting perforating bullet perforation completion, Kong Mi is generally 16 hole/rice, afterwards along with the progress of oil exploitation technology, people recognize that close and penetration depth in perforation hole and piercing aperture play an important role to oil-gas mining, people also have higher requirement to oil exploitation efficient simultaneously, people's more perforator of Gao Kongmi that just begins one's study is progress from 16 hole/rice to 20 hole/rice so, has improved oil, gas extraction rate effectively.Yet from 20 hole/rice to 40 hole/rice, but passed through very long process, because, along with the close increase in perforator hole, perforating bullet is in the moment of blast perforating, the shock wave that one launch hole bullet of elder generation's blast is produced can impact the second launch hole bullet of after-explosion, and this influence is referred to as to disturb between bullet.Interference can cause the perforation of perforating bullet on gun barrel and sleeve pipe to become ellipse between bullet, and wears deeply and can reduce, and along with the increase of annoyance level between bullet, the piercing aperture of perforating bullet and penetration depth can descend by straight line, when serious, can't normally form jet.
For example, domestic existing 178 type perforators, have only a kind of by Kong Mifen: 40 holes/rice perforating bullet are divided into three kinds by punching quality: pure large aperture perforating bullet, deep penetrating charge, big diameter and deep penetrating perforating bumb.The piercing aperture of pure large aperture perforating bullet can reach Ф 25mm, but penetration depth has only about 150mm, and penetration depth is more shallow, and the single-shot pore volume is 0.0245cm3; The deep penetrating charge penetration depth can reach 800mm, but piercing aperture has only about Ф 9mm, and piercing aperture is less, and the single-shot pore volume is 0.0169cm3; The big diameter and deep penetrating perforating bumb has been taken into account the aperture and has been worn deeply, and piercing aperture can reach Ф 20.0mm, and penetration depth can reach 500mm, but Kong Mi is lower, and the single-shot pore volume is 0.0523cm3.Above-mentioned three kind of 178 type perforator all has its limitation, influenced the raising of oil gas well capacity.Generally promptly, the penetration depth of perforating bullet is dark more, and piercing aperture is just more little; Otherwise piercing aperture is big more, and penetration depth is just shallow more.Therefore, the piercing aperture of deep penetrating charge both domestic and external is all less, and wearing of large aperture perforating bullet is deeply all more shallow.
In recent years, along with oil exploitation enters the middle and later periods, the oil and gas reserves on a lot of stratum is few, and formation pressure is low, oil ratio is thicker, the exploitation difficulty is bigger, and the formation sand production that has simultaneously is serious, therefore considers the resources effective exploitation, proposed water flooding recovery again and (beaten a bite well on the next door of oil-gas mining well, by water filling in well, increase strata pressure, thereby the oil-gas mining well on next door can be exploited smoothly) and the new perforating technology requirement of sand control perforation.New perforating technology is also more and more higher to the requirement of perforating bullet, and existing perforating bullet disturbs owing to existing between bigger bullet, thereby can not satisfy instructions for use.
