Abstract
The utility model relates to a well mouth testing connector, which comprises a cone joint, a joint, a pressing rod, a separating sleeve, a pressing cap and a protective cap. The joint and the pressing rod are located on the inner side of the cone joint. The cone joint, the joint and the pressing rod are sequentially in screwed connection from outside to inside. The separating sleeve and the protective cap are located at the lower portion of the outer side of the cone joint. The cone joint, the separating sleeve and the protective cap are sequentially in screwed connection from top to bottom. The pressing cap is located between the separating sleeve and the protective cap. A line containing cavity is formed among the pressing rod, the separating sleeve and the pressing cap. During testing process, a floor signal receiving device can be directly connected to the other end of the well mouth testing connector to penetrate through the connector and cables connected to a testing device placed deep in the mine. Dynamic parameters of the mine can be directly read or recorded through the floor signal receiving device. The whole testing process is simple in operation, testing work efficiency is high, and the well mouth testing connector is suitable for low cost development strategy of oil fields. In addition, when testing operation is finished, users only need to disconnect the floor signal receiving device and the cables and do not have to lift out the testing device in the mine.
Description
Technical field
The utility model relates to the wellhead connector of oil well mouth test usefulness, specifically is a kind of well head test connector.
Background technology
At present, when oilfield test well surveying examination process, the tester at first needs to transfer tester toward testing well in, after testing, the tester of transferring is tripped out just can finish test assignment again, and this test mode exists complicated operation, problem that workload is big.If when the situation that card in test process, occurs meeting, then need to rotate oil well pipe and carry out unfreezing, if the instrument that twines is inextricable, can only carry out bailing, at this moment be not only the workload that has strengthened the tester, the more important thing is to have prolonged the testing time, influenced ordinary production, caused more economic loss.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of well head test connector at the problems referred to above, is used to simplify the test operation flow process, reduces tester's workload.
The utility model is achieved through the following technical solutions: the well head test connector comprises tapered joint head, joint, depression bar, spacer, pressure cap, helmet, wherein, joint, depression bar are positioned at tapered joint head inboard, tapered joint head, joint, the screwed connection successively of depression bar ecto-entad, spacer, helmet are positioned at the outer side-lower of tapered joint head, tapered joint head, spacer, helmet be screwed connection successively from top to bottom, and pressure cap is between spacer and helmet; Form between described depression bar, spacer, the pressure cap and hold the line chamber.
Adopt the good effect of technique scheme: the utility model is connected with well head by the tapered joint head, after the connection, reached the purpose that cable one end is placed this well head test connector outside, so just can the time directly ground signal be received instrument in test is connected to the other end and passes the cable that this connector is connected with the tester of transferring to the down-hole, receive instrument by ground signal and directly read or write down the dynamic parameter of down-hole, whole test process is simple to operate, also reduced simultaneously the workload of test, improved the operating efficiency of test, increased economic benefit, even do not need the tester or the test troop of specialty can finish test jobs yet, be fit to oil field low cost development strategy; In addition, after test jobs is finished, only ground signal need be received the disconnection of instrument and cable and get final product, need not again the tester under the bailing well.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 tapered joint head, 2 joints, 3 depression bars, 4 spacers, 5 pressure caps, 6 helmets, 7 hold the line chamber.
Five, the specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model, and as shown in the figure, the well head test connector comprises tapered joint head 1, joint 2, depression bar 3, spacer 4, pressure cap 5, helmet 6.This connector integral body is cylindrical, and wherein tapered joint head 1 upper outside is provided with screw thread, is used to connect well head.Joint 2, depression bar 3 are positioned at tapered joint head 1 inboard, tapered joint head 1, joint 2, the screwed connection successively of depression bar 3 ecto-entads; Spacer 4, helmet 6 are positioned at tapered joint head 1 outer side-lower, and the screwed connection successively from top to bottom of tapered joint head 1, spacer 4, helmet 6 forms lacuna between spacer 4, the helmet 6, in the lacuna that pressure cap 5 forms between spacer 4 and helmet 6; Form between depression bar 3, spacer 4, the pressure cap 5 and hold line chamber 7, wherein depression bar 3 is used for hermetically-sealed cable, and pressure cap 5 has the effect that compresses the location, and helmet 6 has the effect of sealing, protection, holds line chamber 7 and has the effect of holding cable.
Before the test, at first cable one end is placed this well head test connector outside, the other end passes this connector and is connected with tester, and tester connects transfers to the down-hole, this well head test connector is connected with well head again; During test, directly ground signal being received instrument is connected with the cable that places this well head test connector outside, just can read or write down out the dynamic parameter of down-hole, in whole test process, operating process is simple, and tester that need not be professional or test troop also can finish test jobs, owing to simplified operating process, also greatly reduce tester's workload, improved operating efficiency, increased economic benefit.
