Equal oil gas block is widely applied, and year-on-year conventional drilling raises speed 3 times or more.The gas bearing interval of hardly possible boring property difference is bored using gas
Well speed-raising is more universal；However, (≤10000m when drilling strata goes out a small amount of natural gas3/ d), circulatory mediator is converted to lazy
Property gas nitrogen to avoid down-hole blasting accident generation, but usually because lack annular preventer, drilling tool size can not pass through greatly
The reasons such as swivel control head assembly, when making a trip, replacing the spacious well operations such as glue core, there are natural gases may overflow well head, band
Larger security risk is carried out.
When carrying out spacious well operations such as " make a trip, replace glue core " under the conditions of there is no solution stratum to go out a small amount of natural gas at this stage
Natural gas overflows the effective measures of this problem of well head, current mainly to dispel and overflow by opening the explosion-proof exhaust fan of rig floor or more
Natural gas out prevents its aggregation.There are many deficiencies for this processing method:

For junction to the natural gas that may be overflowed, there are larger security risks, especially carry out percussion operation；
3. because being unable to ensure field work safe, the (≤10000m when drilling strata goes out a small amount of natural gas3/ d), usually by
Compel to terminate gas drilling operation in advance, is unfavorable for the performance of speed-raising advantage.
In addition, in general, sediment outflow pipeline uses flanged joint in the well site of gas drilling, preferably straight to connect out well site
Outside.Since sediment outflow pipeline diameter is big, weight is big, when most, the docking between live sediment outflow pipeline is all highly difficult, is difficult
Accomplish once to dock in place.In general, can all have gap between two sediment outflow pipelines.In order to guarantee that connection is accomplished to fit together perfectly, need
The flange (or clip) of line end to be touched together, is then fastened using modes such as artificial lift, crowbar sleds.Due to
Sediment outflow pipeline weight is very big, causes pipeline to install inconvenient.This not only considerably increases the installation exercise time, increases
The workload and working strength of staff, also improves operating personnel's cost and crane cost of use, or even will cause brill
Machine etc. stops, and extends the serious consequence of drilling period.
