Abstract
The utility model provides a kind of pressure testing device, comprising: supervisor, pressure testing rifle; Described supervisor is hollow structure, and described supervisor both sides inwall is respectively arranged with internal thread; Described pressure testing rifle gun barrel is provided with external screw thread, and described supervisor and pressure testing rifle are threaded connection; Described pressure testing rifle is arranged and is connected with a high pressure line; The described high pressure line other end arranges and is provided with crossover sub.The utility model provide a kind of can the pressure testing device of on-site voltage-measuring, by the variable buckle effect of changeover plug, can conveniently internally jet-preventing tool carry out pressure testing, and save resource, improve well control safety.
Description
Technical field
The utility model belongs to field of petroleum machinery, relates in particular to a kind of pressure testing device.
Background technology
Very high to the requirement of well control in drilling process; Well control safety is one of on-the-spot most important action.Wherein, interior jet-preventing tool is a class well control instrument of on-the-spot extensive use, and the safety of interior jet-preventing tool has very important effect to full well well control safety.Under normal circumstances, situ of drilling well requires that interior jet-preventing tool every three months wants pressure testing once, to guarantee safety.
But current most of drilling team does not have special pressure testing device, pressure testing cannot be carried out at the scene.Each pressure testing all needs that interior jet-preventing tool is delivered to well control workshop, base from scene and carries out pressure testing, delivers to aboveground after having tried again.Do like this and waste time and energy, pressure testing can not be carried out by internal jet-preventing tool in time, and the technology status of the internal jet-preventing tool of Field Force is felt unsure of, and jeopardizes well control safety most probably.According to this situation, we combine on-the-spot actual, have manufactured this pressure testing device.
Utility model content
In order to overcome above-mentioned shortcoming of the prior art, the utility model provides a kind of pressure testing device, comprising: supervisor, pressure testing rifle;
Described supervisor is hollow structure, and described supervisor both sides inwall is respectively arranged with internal thread;
Described pressure testing rifle gun barrel is provided with external screw thread, and described supervisor and pressure testing rifle are threaded connection;
Described pressure testing rifle is arranged and is connected with a high pressure line;
The described high pressure line other end arranges and is provided with crossover sub.
Described supervisor's inwall is provided with an O type seal groove.
The specification of described crossover sub is two or more.
The utility model has the advantages that: provide a kind of can the pressure testing device of on-site voltage-measuring, by the variable buckle effect of changeover plug, can conveniently internally jet-preventing tool carry out pressure testing, and save resource, improve well control safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
1, be responsible for; 2, pressure testing rifle; 3, changeover plug; 4, seal groove; 5, external screw thread; 6, high pressure line; 7, internal thread.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of pressure testing device, comprising: supervisor 1, pressure testing rifle 2;
Described supervisor 1 is hollow structure, and described supervisor 1 both sides inwall is respectively arranged with internal thread 7;
Described pressure testing rifle 2 gun barrel is provided with external screw thread 5, and described supervisor 1 is threaded connection with pressure testing rifle 2;
Described pressure testing rifle 2 is arranged and is connected with a high pressure line 6;
Described high pressure line 6 other end arranges and is provided with crossover sub 3.
Specifically, in practical operation, according to field condition, each well is all equipped with casing head pressure testing rifle, what its action pressure-testing joint was conventional have Z 1 ", Z 11/8 ", Z 1/2 " three kinds of specifications.And conventional interior jet-preventing tool has 5 " square sucker rod down cock, 5 " drop-in check valve, 5 " arrow type back pressure valve (being 411*410 to buckle), 3 " square sucker rod down cock, 3 " drop-in check valve, 3 " arrow type back pressure valve (being 311*310 to buckle), 5 " upper kelly cock (630 anti-* 631 left-hand threads), 3 " upper kelly cock (630 anti-* 631 left-hand threads) etc. several.
As the preferred implementation of one of the present utility model, the specification of described crossover sub 3 is two or more.
Specifically, utilize the crossover sub of different size, the pressure testing gun joint button-type concrete according to each drilling team, 12 7/8 " external upset tubing pin thread * Z 1 " (or Z1 1/8 ", Z " processed by every mouthful of well, determine according to pressure testing gun joint button-type) button variable buckle joint, reprocess 1 41,0*2 7/8 " outer heat-bodied oil pipe box variable buckle joint, 1 31,0*2 7/8 " outer heat-bodied oil pipe box variable buckle joint, 1 630 anti-* 2 7/8 " outer heat-bodied oil pipe box variable buckle joint.According to on-site voltage-measuring needs, this pressure testing device needing jet-preventing tool and the utility model in pressure testing to provide is realized variable buckle by crossover sub and is connected, pressure testing can be carried out easily.
Described supervisor 1 inwall is provided with an O type seal groove 4.
Specifically, conveniently joint connection in site and sealing, " O " type seal groove together with can processing on the box sealing station terrace connected with interior jet-preventing tool in process, add " O " RunddichtringO together when connecting at the scene and be used for sealing, directly seal by " O " sealing ring to realize pressure testing device and interior jet-preventing tool, thus facilitate on the chain wrench of scene and detain.
In addition, carry out in pressure testing process at this pressure testing device using the utility model to provide, jet-preventing tool must be in closed condition, as far as possible first in interior jet-preventing tool, fills test medium (clear water or diesel oil); And then carry out suppressing operation.
