Background technology
Need carry out the throttle well killing operation to the high pressure high gas rate well in the oil recovery well workover.Because the throttling casing pressure is high, the gas overflow amount is big, the phenomenon that choke manifold damages is more serious.Simultaneously, because the well head burst resistance can not bear high throttling casing pressure, often adopt anti-circulation throttling kill job, and the burden that has alternately more increased the weight of choke manifold repeatedly of positive and negative circulation kill job badly influences well control safety.Conventional kill manifold only possesses auxiliary open flow, the function of anti-circulation kill-job inlet is provided, and does not give full play to significant role, need improve.
The utility model content
The purpose of the utility model is: a kind of multi-functional kill manifold linkage is provided; Be based on existing well control equipment condition, bring into play the kill manifold function, rationally share the heavy burden of choke manifold; Effectively reducing the throttle well killing operating risk, is to improve the well control equipment to resist the well control risk ability.
The technical scheme that the utility model adopts is: multi-functional kill manifold linkage comprises open flow manifold, kill manifold, wellhead blowout preventor group, cementing head, the anti-kill line that circulates, backshuttle line, feed flow interface, choke manifold, fracturing unit truck group, feed flow pipeline and the anti-kill-job suction line that circulates.It is characterized in that: the top at well head is fixed with four-way, and the top of four-way also is fixed with the wellhead blowout preventor group in the bottom of rig floor; The cementing head on wellhead blowout preventor group top connects anti-circulation kill line; On the top of well head and on the four-way of wellhead blowout preventor group bottom, be connected with two pipelines, wherein connect kill manifold on a pipeline; The top of kill manifold connects backshuttle line; Two arrival ends of kill manifold are connected with anti-circulation kill-job suction line with the feed flow pipeline respectively through the feed flow interface; The feed flow pipeline is connected the fracturing unit truck group with the other end of anti-circulation kill-job suction line; The port of export of kill manifold connects the open flow manifold through pipeline; Another pipeline that four-way connects connects choke manifold.Open flow manifold, kill manifold, wellhead blowout preventor group, cementing head, choke manifold and fracturing unit truck group are existing equipments, and city's field energy is purchased.
Adopt module combinations and structural optimization method; Realized the function expansion: serial connection one cover open flow manifold behind kill manifold, not only for the throttle well killing operation provides an alternate channel, in case choke manifold damages; Can launch the open flow manifold immediately, guarantee the continuity of kill job; Also for anti-circulation throttling kill job a standing passage is provided, Each performs its own functions with choke manifold, helps replacing repeatedly of positive and negative circulation kill job.On kill manifold, increase by one group of anti-kill-job feed flow gate valve that circulates, be connected to anti-circulation kill-job fracturing unit truck group feed flow, avoided the incidental pipe explosion accident of flexible pipe feed flow, guarantee kill job safety through pipeline.Through being connected of anti-circulation kill line and open flow manifold, can realize anti-circulation kill job.Be connected with the pipeline of fracturing unit truck group through anti-circulation kill-job feed flow gate valve, realize anti-circulation kill-job feed flow.
Sketch the course of work of multi-functional kill manifold linkage.Consult Fig. 1.
1, getting into kill manifold 2 by slush pump pumping drilling fluid warp let-off backshuttle line 7, is fracturing unit truck group 10 feed flows through feed flow interface 8, feed flow pipeline 11 again;
2, under the closing well condition, get into kill manifold 2 by fracturing unit truck group 10 pumping drilling fluids through anti-circulation kill-job suction line 12, get into mineshaft annulus then;
3, the drilling fluid that goes out from the drilling tool internal return gets into open flow manifold 1 through cementing head 5, the anti-kill line 6 that circulates;
4, through regulating the throttle valve control casing pressure on the open flow manifold 1, carry out throttle well killing.
The beneficial effect of the utility model: the multi-functional kill manifold linkage of the utility model, 1, make full use of existing well control equipment condition, realized the function expansion.2,,,, improved the well control equipment and resisted the blowout risk ability for anti-circulation kill-job fracturing unit truck group provides safe liquid feeding channel for anti-circulation throttling kill job provides a standing passage for the throttle well killing operation provides an alternate channel.3, configuration is reasonable, and easy for installation, applicability is strong.
