Abstract
The utility model provides a throttling and well killing integrated circulating manifold. The problems that in drilling equipment in petroleum and natural gas industries, the frequently-used circulating manifold in a pressure circulating system only has the effect of throttling, so that when blowout happens, another well killing manifold is required to replace the manifold, time is wasted, and danger is increased are solved. The throttling and well killing integrated circulating manifold comprises two four-fork pipes, wherein two three-fork pipes and a connecting pipe are connected between the two four-fork pipes; the four-fork pipes and one three-fork pipe I form a well killing pipe; an outlet II is formed in the well killing pipe; the four-fork pipes and the other three-fork pipe II form a boosting pipe; an outlet III is formed in the boosting pipe; and the four-fork pipes and the connecting pipe form a normal working pipe; a gate valve I is arranged on one four-fork pipe, and an outlet I and an outlet IV are formed in each four-fork pipe. The throttling and well killing integrated circulating manifold serves as the manifold which integrates the functions of throttling and well killing.
Description
Technical field:
The utility model relates to a kind of throttling, kill-job integrated circular manifold, belongs to drilling equipment technical field in the industrial gas oil.
Background technology:
The circulation manifold of commonly using in the pressure circulation system in the drilling equipment in the industrial gas oil can only be done throttling usefulness, and the kill manifold that need to change the outfit in addition when blowout occurs wastes time, and has increased risk.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of throttling, kill-job integrated circular manifold, can play simultaneously the effect of throttling, compression, reliable operation.
Above-mentioned purpose realizes by following technical scheme:
Throttling, kill-job integrated circular manifold, comprise two four breeches pipes, connect two Y-pipes and a tube connector between described two four breeches pipes, described four breeches pipes and a Y-pipe wherein form the kill-job pipeline, has outlet two on the described kill-job pipeline, described four breeches pipes and an other Y-pipe two form pressure piping, has outlet three on the described pressure piping, form the normal operation pipeline between described four breeches pipes and the described tube connector, be provided with gate valve one on one of them described four breeches pipe, have respectively outlet one and outlet four on described four breeches pipes.
Described throttling, kill-job integrated circular manifold are provided with flap valve and gate valve two on the described kill-job pipeline, described flap valve and described gate valve two lay respectively at the both sides of described Y-pipe.
Described throttling, kill-job integrated circular manifold are provided with gate valve three and gate valve four on the described pressure piping, described gate valve three and gate valve four lay respectively at the both sides of described Y-pipe.
Described throttling, kill-job integrated circular manifold are provided with gate valve five and gate valve six on the described normal operation pipeline.
Beneficial effect:
The utility model is realized the function of throttling, kill-job simultaneously, does not need to change kill manifold when blowout occurs, and saves time reliable operation.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, four breeches pipes; 2, tube connector; 3, Y-pipe one; 4, outlet two; 5, Y-pipe two; 6, outlet three;

The specific embodiment:
Embodiment 1:
As shown in Figure 1: throttling of the present utility model, kill-job integrated circular manifold, comprise two four breeches pipes 1, connect two Y-pipes and a tube connector 2 between described two four breeches pipes, described four breeches pipes and a Y-pipe wherein 1 form the kill-job pipeline, has outlet 24 on the described kill-job pipeline, described four breeches pipes and an other Y-pipe 25 form pressure piping, has outlet 36 on the described pressure piping, form the normal operation pipeline between described four breeches pipes and the described tube connector, be provided with gate valve 1 on one of them described four breeches pipe, have respectively outlet 1 and outlet 49 on described four breeches pipes.
Embodiment 2:
Embodiment 1 described throttling, kill-job integrated circular manifold are provided with flap valve 10 and gate valve 2 11 on the described kill-job pipeline, described flap valve and described gate valve two lay respectively at the both sides of described Y-pipe.
Embodiment 3:
Embodiment 1 described throttling, kill-job integrated circular manifold are provided with gate valve 3 12 and gate valve 4 13 on the described pressure piping, described gate valve three and gate valve four lay respectively at the both sides of described Y-pipe.
Embodiment 4:
Embodiment 1 described throttling, kill-job integrated circular manifold are provided with gate valve 5 14 and gate valve 6 15 on the described normal operation pipeline.
The course of work:
During normal operation, all the other pipe valves are closed except the normal operation pipeline.The drilling well circulation fluid enters manifold from exporting one, flows out to outlet four through the normal operation pipeline.Play normal choke manifold effect;
When requiring to increase the drilling well circulating fluid flow rate, open gate valve three and gate valve four on the pressure piping, the drilling well circulation fluid respectively from export three and the outlet four outflows;
When abnormal conditions occurring and need kill-job, close normal operation pipeline and pressure piping, close on the kill-job pipeline gate valve two, inject well killing fluid two from exporting, well killing fluid is pressed into the shaft bottom through flap valve.Prevent simultaneously the well killing fluid regurgitate.Play the effect of normal kill manifold;
When needs further increase the kill-job amount, open the gate valve two on the kill-job pipeline, squeeze into well killing fluid from exporting four.Recover fast bottom pressure.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-described embodiment, also comprises by above technical characterictic being equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model belongs to those skilled in the art's common practise.
