Abstract
The utility model discloses an automatic drill rod washing device which comprises a cylindrical body (1). A sprayer (2) is arranged on the wall of the body (1), the water outlet end of the sprayer (2) faces the interior of the body (1), and the water inlet end of the sprayer (2) is connected to a water pump through a water inlet pipe (4). When the automatic drill rod washing device is used, the automatic drill rod washing device is arranged on a mouse hole, the water inlet pipe is connected to the water pump to pump seawater, the seawater is sprayed out of the sprayer, automatic drill rod washing can be achieved, and therefore the operation time of a driller is saved, and operation efficiency is improved.
Description
Technical field
The utility model belongs to the technical field of oilfield drilling, while specifically referring to a kind of trip-out, drilling rod is got rid of into rat hole, automatically cleans the device of drilling rod.
Background technology
At present, when drillng operation, the situation of mud cake thickening often appears.Therefore during trip-out, will be stained with a large amount of mud cakes on drilling rod, need driller to spray water these mud cakes are washed out, but in order not change the performance of drilling fluid, scene often directly not aimed at well head and rinsed, but drill string is splitted into drilling rod, be placed on rig floor and clean.But this cleaning process needs driller to carry out manual operation, and sometimes a drilling rod need to rinse 10 ~ 20min, and the washing time of a trip-out can surpass 12 hours, have a strong impact on the operation timeliness.
Above-mentioned discussion content purpose is to introduce to the reader various aspects of technology that may be relevant to the various aspects of the present utility model that below will be described and/or advocate, believe that this discussion content helps to provide background information for the reader, to be conducive to understanding better various aspects of the present utility model, therefore, should be appreciated that it is to read these discussions with this angle, rather than admit prior art.
The utility model content
The purpose of this utility model is to avoid deficiency of the prior art and a kind of auto-flushing boring rod set is provided, to solve in field operation the problem that needs driller's manual flushing drilling rod and affect the operation timeliness.
The purpose of this utility model is achieved through the following technical solutions:
A kind of auto-flushing boring rod set is provided, comprises the body of tubular, be provided with shower nozzle on the wall of described body, the water side of described shower nozzle is towards the inside of body, and the water inlet end of shower nozzle is connected to water pump through water inlet pipe.
Wherein, described shower nozzle is four, with the axis of body, is 60 ° of angles.
Wherein, described four shower nozzles are arranged along the even interval of the axis direction of body, and are uniformly distributed on the plane of projection perpendicular to axis.
Wherein, described body two ends are provided with the righting circle, and the internal diameter of described righting circle is less than the internal diameter of described body.
Wherein, the external diameter of described body is 254mm, and internal diameter is 241.3mm, and length is 1.0m, and the internal diameter of described righting circle is 177.8mm.
Wherein, the spacing of described adjacent two shower nozzles on the axis direction of body is 10cm.
Owing to having adopted above-mentioned structure, the utility model is positioned on rat hole while using, and water inlet pipe is connected water pump suction seawater, and seawater sprays from shower nozzle, just can realize the auto-flushing drilling rod, thereby saves driller's operating time, improves the operation timeliness.
The beneficial effects of the utility model:
1, simple in structure, cost of investment is low;
2, the operation timeliness is improved, thereby has reduced operating cost;
3, simple to operation, oil gas field extensive use at sea.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model,, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain according to the following drawings other accompanying drawing.
