Abstract
The utility model relates to the drill stem washout testing and analysis system that wellbore construction prevents drilling tool accident.In wellbore construction, drilling tool accident can cause unit in charge of construction's heavy losses, brings loss even inestimable, in current oil drilling to unit in charge of construction's property and personal security, drill stem washout is generally only by artificial micro-judgment, inaccurate, not in time, easily cause drilling failure.The utility model proposes the drill stem washout testing and analysis system that wellbore construction prevents drilling tool accident, determination and analysis and balanced gas are integrated by this system, and accuracy of judgement is quick, error free.Comprise drilling tool, the special gas detector be connected with drilling tool, special gas detector connects drill stem washout analyzer, wherein, described drill stem washout analyzer is also connected with drilling circulation pump and special gas injector, described special gas injector one end is connected to drilling well by pipeline, and pipeline of leading up to is connected to drilling circulation pump.
Description
Technical field
The utility model is well drilling tool detection system technical field, particularly relates to the drill stem washout testing and analysis system that wellbore construction prevents drilling tool accident.
Background technology
In wellbore construction, drilling tool accident can cause unit in charge of construction's heavy losses, brings loss even inestimable, in current oil drilling to unit in charge of construction's property and personal security, drill stem washout is generally only by artificial micro-judgment, inaccurate, not in time, easily cause drilling failure.
Utility model content
For solving the deficiencies in the prior art, the utility model proposes the drill stem washout testing and analysis system that wellbore construction prevents drilling tool accident, determination and analysis and balanced gas are integrated by this system, and accuracy of judgement is quick, error free.
Be specially, wellbore construction prevents the drill stem washout testing and analysis system of drilling tool accident, comprise drilling tool, the special gas detector be connected with drilling tool, special gas detector connects drill stem washout analyzer, and wherein, described drill stem washout analyzer is also connected with drilling circulation pump and special gas injector, described special gas injector one end is connected to drilling well by pipeline, and pipeline of leading up to is connected to drilling circulation pump.
Preferably, described special gas injector both sides are respectively arranged with valve;
Accompanying drawing explanation
Fig. 1 is system annexation figure of the present utility model;
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, wellbore construction prevents the drill stem washout testing and analysis system of drilling tool accident, comprise drilling tool 10, the special gas detector 3 be connected with drilling tool 10, special gas detector 3 connects drill stem washout analyzer 2, wherein, described drill stem washout analyzer 2 is also connected with drilling circulation pump 1 and special gas injector 4, described special gas injector 4 one end is connected to drilling well 9 by pipeline 7, pipeline 7 of leading up to is connected to drilling circulation pump 1, and described special gas injector 4 both sides are respectively arranged with valve 5,6.
Its operating principle is, in wellbore construction, when normally working, by drilling equipment circulation of drilling fluid pump circulating mud, from drilling tool to shaft bottom, completes a circulation by being recycled to ground, if this circulation is a threshold range of setting-up time, then thinks that drilling tool is normal.
When ground installation works well, decline if run into drilling circulation pump 1 pump pressure, Open valve 5 and 6, starts special gas injector 4 and in ground pipeline 7, injects special gas to drilling well 9, participate in circulation.If there is thorn leakage can from drilling tool midway counter go out, the special gas arriving ground is poor if having time compared with normal time in the time of special gas detector 3, this information can be passed to drill stem washout analyzer 2 by special gas detector 3, obtain stinging leak source by drill stem washout analyzer 2, reach and accurately and timely prevent accident.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
