Embodiment
In order to make those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings to the present invention
It is further described.
As shown in Figure 1, a kind of offshore oil and gas field high efficiency composition completion method of the present invention, its perforation tubular column used
Include successively from bottom to top：Gun breech 1, perforating gun 2, igniter head 3, shock absorption oil pipe 4, damper 5, negative pressure boring device 6, RTTS envelopes
Every device 7, pressure-transmitting joint 8, safety joint 9, bumper jar 10, RD circulating valves 11, heavy weight drill pipe 12, isotope connector 13 and it is sent into brill
Tool 14.Wherein, the negative pressure boring device 6 does not install shear pin, and the RD circulating valves 11 carry ball valve.
Each self-structure of component of perforation tubular column and the connection structure between miscellaneous part are the prior art, therefore are not made
Detailed description.The perforation tubular column used in the present invention is the improvement made on traditional tubing string, wherein main improvement
It is as follows.
（1）The negative pressure boring device 6 does not install shear pin, in this way, negative pressure boring device 6 can during the well entry process
Automatically open up, realize automatic grouting, tubing string realizes overbalanced perforation by applied pressure by annulus afterwards in place.
（2）The RD circulating valves 11 carry ball valve, in this way, applied pressure by annulus opens RD circulating valves after perforation open flow
11, while the lower ball valve of RD circulating valves 11 is closed, and avoids RD circulating valves from opening impact of the instantaneous pressure to lower part bore hole, at the same time
Ensure well control safety.
