In controlled pressure drilling work progress, site engineer finds, during pressure control choke manifold controlled pressure drilling, often blocks, and causes controlled pressure drilling time-out, conversion process flow process, affects controlled pressure drilling construction effect.
Choke manifold plugging reason is as follows by analysis: 1, defective glue core falls block blocking; 2, bulky grain sealing agent blocking; 3, block blocking is fallen in cave-in.
When there is blocking, often need choke valve or square four-way to take apart, manually will block object and take out, if volume is comparatively large, need to remove by the heavy-duty machineries such as fork truck are auxiliary.After cleaning blocking object, reconnect installation choke manifold, pressure testing again must be carried out to manifold on request, guarantee that the flange energy pressure-bearing of taking apart is qualified.Therefore, site operation cleaning blocking is not only required great effort but also time-consuming.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of block-resistant type pressure control choke manifold, the arrangement achieves and can filter foreign material, effectively prevent choke manifold from blocking, the foreign material of accumulation can be cleared up simply and easily, without the need to taking choke valve or square four-way apart, alleviate the labour intensity of personnel, time saving and energy saving, shorten the controlled pressure drilling production time.Overcome existing choke manifold easily to block, cleaning blocking object need take choke valve or square four-way apart, the deficiency wasted time and energy.
Technical solution adopted in the utility model is: a kind of block-resistant type pressure control choke manifold, comprises flap type I, square four-way I and flap type II, square four-way I left end connects flap type I, square four-way I right-hand member connects flap type II, four-way blind plate I is installed in square four-way I lower end, square four-way I upper end connects choke valve by connecting short section, choke valve right-hand member connects flap type III, flap type III right-hand member is connected with square four-way II left end, square four-way II lower end is connected with square four-way III upper end by connecting short section, square four-way III lower end is by four-way blind plate II shutoff, square four-way III left end is connected with flap type II by connecting short section, filter screen pipe nipple comprises cylindric filter screen body, filter screen body upper and lower side is uncovered, side sidewall is evenly provided with multiple filter screen hole milling in the middle part of filter screen body, the aperture area of filter screen hole milling is 1/3rd of choke valve minimum-value aperture area, the another side filter screen body sidewall that filter screen hole milling is corresponding has scalloped channels, filter screen body lower end is provided with lug edge, it is inner that filter screen pipe nipple is placed in square four-way I, lug is along being fixed in square four-way I right-hand member body vias inner walls by fixed screw, filter screen body with the side sidewall of filter screen hole milling just to square four-way I upper end body passage, filter screen body upper end body passage is connected with square four-way I left end body passage, scalloped channels on filter screen body sidewall is just to four-way blind plate I.
The beneficial effects of the utility model are: the utility model can filter foreign material, effectively prevent choke manifold from blocking, the foreign material of accumulation can be cleared up simply and easily, without the need to taking choke valve or square four-way apart, alleviate the labour intensity of personnel, time saving and energy saving, shorten the non-controlled pressure drilling production time.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of filter screen pipe nipple.

Detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of block-resistant type pressure control choke manifold, comprises flap type I 6, square four-way I 8 and flap type II 10, square four-way I 8 left end connects flap type I 6, square four-way I 8 right-hand member connects flap type II 10, four-way blind plate I 7 is installed in square four-way I 8 lower end, square four-way I 8 upper end connects choke valve 11 by connecting short section 5, choke valve 11 right-hand member connects flap type III 12, flap type III 12 right-hand member is connected with square four-way II 13 left end, square four-way II 13 lower end is connected with square four-way III 15 upper end by connecting short section 5, square four-way III 15 lower end is by four-way blind plate II 14 shutoff, square four-way III 15 left end is connected with flap type II 10 by connecting short section 5, filter screen pipe nipple 9 comprises cylindric filter screen body 1, filter screen body 1 upper and lower side is uncovered, side sidewall is evenly provided with multiple filter screen hole milling 2 in the middle part of filter screen body 1, the aperture area of filter screen hole milling 2 is 1/3rd of choke valve 11 minimum-value aperture area, another side filter screen body 1 sidewall of filter screen hole milling 2 correspondence has scalloped channels, filter screen body 1 lower end is provided with lug along 4, it is inner that filter screen pipe nipple 9 is placed in square four-way I 8, lug is fixed in square four-way I 8 right-hand member body vias inner walls along 4 by fixed screw 3, filter screen body 1 with the side sidewall of filter screen hole milling 2 just to square four-way I 8 upper end body passage, filter screen body 1 upper end body passage is connected with square four-way I 8 left end body passage, scalloped channels on filter screen body 1 sidewall is just to four-way blind plate I 7.
During controlled pressure drilling, open flap type I 6 and flap type III 12, close flap type II 10, drilling fluid is by choke valve 11, carry out throttling pressure control, drilling fluid is before entering choke valve 11, filtered by the filter screen pipe nipple 9 of square four-way I 8 inside, pile up when the foreign material in filter screen pipe nipple 9 and acquire a certain degree, when finding that choke valve 11 upstream pressure (casing pressure) rises to limit value, open flap type II 10, close flap type III 12, drilling fluid is directly by flap type I 6 and flap type II 10, and foreign material are washed away by instantaneous flushing filtering net pipe nipple 9.Now, from well head high-pressure hose to choke manifold, outlet is straight-through pipeline, without any the obstacle that turns round, therefore the foreign material piled up in filter screen pipe nipple 9 are directly taken away by drilling fluid, reach the object of flushing filtering net pipe nipple 9.If comparatively during Severe blockage, flap type I 6 is closed in termination of pumping, opens four-way blind plate I 7, directly observes stopping state, clean out obstruction immediately from filter screen pipe nipple 9 scalloped channels.If there is the situation of Severe blockage, can directly change filter screen pipe nipple 9, speed.If when running into conventional drilling, drilling fluid directly can walk put-through channel, avoids the blocking of choke valve 11.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
