Abstract
The utility model discloses a well shut-in device with an internal thread well shut-in pipe nipple and relates to a well shut-in technology for oil and gas wells in oil and gas fields. The defects of a welding manner are overcome by the well shut-in device with the internal thread well shut-in pipe nipple. The well shut-in device is formed by connecting the well shut-in pipe nipple, a clamp -type gate valve and a pressure gage bushing and casing core. The pressure gage bushing and casing core and the clamp-type gate valve are in threaded connection; the clamp-type gate valve and the well shut-in pipe nipple are connected by a clamp; the well shut-in pipe nipple is provided with internal threads; and the well shut-in pipe nipple is connected with a downhole casing pipe by adopting 5.5'' long circular threads at a taper of 1:16. The well shut-in device with the internal thread well shut-in pipe nipple disclosed by the utility model has the meaning that the well shut-in device is connected with the downhole casing pipe by adopting screw threads, and thus, the pressure of an oil well can be displayed in real time. The well shut-in device is simple in structure, is fast to install and is convenient to operate.
Description
Technical field: the utility model relates to oil, gas field oil, gas well shut-in well technology, especially a kind of shut-in well device that has internal thread shut-in well pipe nipple.
Background technology: oil gas field crude oil/gas production deficiency, take the intermittently starting measure, need oil, the gas well of interim sealing or the oil of sealing up for safekeeping for a long time, gas well; The 2nd, the oil that new well and operation completion can not in time be exploited, the interim sealing of gas well; The 3rd, need the interim sealing of the water injection well of intermittent water filling.When sealing for above oil gas well, mostly adopt welding, steel plate and Socket welding are connected together, seal, such technology complicated operation, dangerous, waste time and energy.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, easy to operate a kind of shut-in well device that has internal thread shut-in well pipe nipple, it has overcome the shortcoming of welding manner, the purpose of this utility model is to realize like this, it is to be mended core and be formed by connecting by shut-in well pipe nipple, clamping hoop type slide valve, pressure meter cover, the pressure meter cover is mended core and is threaded with the clamping hoop type slide valve, and clamping hoop type slide valve and shut-in well pipe nipple are by clamp connection.On the shut-in well pipe nipple internal thread is arranged." oval screw thread, tapering 1:16 are connected with down-hole casing in shut-in well pipe nipple employing 5.
Meaning of the present utility model is, takes screwed connection with down-hole casing, can show oil well pressure in real time.This apparatus structure is simple, and is quick for installation, easy to operate.
The scope of application of utility model: the one, crude oil/gas production deficiency is taked the intermittently starting measure, needs oil, the gas well of interim sealing or the oil of sealing up for safekeeping for a long time, gas well.The 2nd, the oil that new well and operation completion can not in time be exploited, the interim sealing of gas well.The 3rd, need the interim sealing of the water injection well of intermittent water filling.
Description of drawings: Fig. 1 is a kind of structural representation of novel shut-in well device, among the figure 1, shut-in well pipe nipple 2, clamping hoop type slide valve 3, pressure meter cover mend core
The specific embodiment: embodiment 1, the utility model are to be mended core 3 and be formed by connecting by the pipe nipple 1 of shunting in a well, clamping hoop type slide valve 2, pressure meter cover, and the pressure meter cover is mended core 3 and is threaded with clamping hoop type slide valve 2, and clamping hoop type slide valve 2 and shut-in well pipe nipple 1 are by clamp connection.
On embodiment 2, the shut-in well pipe nipple 1 internal thread is arranged.
Embodiment 3, shut-in well pipe nipple 1 adopt 5, and " oval screw thread, tapering 1:16 are connected with down-hole casing.
