Abstract
A kind of oil exploitation level pressure blowout hookup, it is related with oil exploitation, one lower cavity is set, valve ball is set in lower cavity, on valve ball top, pressure spring is set, in lower cavity bottom, connector is set, connector outer end is tightly connected by screw thread and wellhead casing pipe, in lower cavity top, several through-holes are set, a cylindrical inner cavity is vertically arranged on several through-holes, it is less than the floating ball of oil density in interior intracavitary one density of setting, on the inner cavity top, one exhaust outlet is set, and a cylindrical exocoel is set in inner cavity peripheral hardware, in intracavity sidewall, if dry side stomata is arranged in lower position, when exhaust: floating ball is located at the lower part of inner cavity, gas, which enters lower cavity through connector and opens valve ball warp several through-holes, enters inner cavity, enter exocoel using the side stomata below floating ball, again from the side stomata above floating ball Into inner cavity, then it is discharged from exhaust outlet, when there is crude oil in gas, floating ball floats, and withstands exhaust outlet, and crude oil will not be ejected.
Description
Technical field
The utility model is related with oil exploitation, specifically a kind of oil exploitation level pressure blowout hookup.
Background technique
In oil field development, especially some higher wells of gassiness, after entering gas in deep well pump, oil not can enter
Pump keeps pumping not fuel-displaced next, under serious situation, is easy to appear gas lock, has very big negative effect to the production of oil well.At present
Most common method is to open wellhead casing pipe air lock door, is periodically deflated, and thus needs people station to put certain time in well head and closes again
Fall, virtually increase many human costs in this way, or wellhead casing pipe gate is normally opened, but accompanying problem is that, one
Denier pump goes wrong, and is easy to appear set spray phenomenon, pollutes environment.
Summary of the invention
A kind of oil exploitation level pressure blowout hookup is vertically arranged a cylindrical lower cavity, is arranged in lower cavity
Pressure spring is arranged on valve ball top in valve ball, connector is arranged in lower cavity bottom, connector outer end passes through screw thread and well head set
Seal of tube connection, is arranged several through-holes in lower cavity top, it is characterized in that: being vertically arranged a cylinder on several through-holes
The inner cavity of shape, at this, interior intracavitary one diameter of setting is less than intracavity diameter, density is less than the floating ball of oil density, and makes the floating ball
This it is interior it is intracavitary move freely above and below, on the inner cavity top, one exhaust outlet is set, and inner cavity peripheral hardware set one it is cylindrical
Exocoel, if in intracavity sidewall, lower position dry side stomata is set, when exhaust: floating ball is located at the lower part of inner cavity, and gas is through company
Interface, which enters lower cavity and opens valve ball warp several through-holes, enters inner cavity, enters using the side stomata below floating ball outer
Chamber, then enter inner cavity from the side stomata above floating ball, it is then discharged from exhaust outlet, when there is crude oil in gas, floating ball floats, top
Firmly exhaust outlet, crude oil will not be ejected.The floating ball is plastic material, and valve ball is steel.
Detailed description of the invention
Fig. 1 be in the utility model in wellhead casing pipe without air pressure when state diagram.
Fig. 2 is state diagram when having gas in the utility model in wellhead casing pipe.
Fig. 3 is state diagram when having gas in the utility model in wellhead casing pipe and having crude oil.
In figure: 1, lower cavity, 2, valve ball, 3, pressure spring, 4, connector, 5, through-hole, 6, inner cavity, 7, floating ball, 8, exhaust outlet,
9, exocoel, 10, side stomata.
Specific embodiment
In Fig. 1, Fig. 2, Fig. 3: it is vertically arranged a cylindrical lower cavity 1, valve ball 2 is set in lower cavity 1,
Pressure spring 3 is set on 2 top of valve ball, connector 4 is set in lower 1 bottom of cavity, 4 outer end of connector passes through screw thread and wellhead casing pipe
It is tightly connected, several through-holes 5 is set at the top of lower cavity 1, it is characterized in that: being vertically arranged a circle on several through-holes 5
Cylindrical inner cavity 6 is arranged a diameter less than intracavity diameter, density in the inner cavity 6 and is less than the floating ball 7 of oil density, and makes
The floating ball 7 moves freely above and below in the inner cavity 6, an exhaust outlet 8 is arranged on 6 top of inner cavity, and be arranged outside inner cavity 6
One cylindrical exocoel 9, if in 6 side wall of inner cavity, lower position dry side stomata 10 is set, when exhaust: floating ball 7 is located at interior
The lower part of chamber 6, gas, which enters lower cavity 1 through connector 4 and opens valve ball 2, enters inner cavity 6 through several through-holes 5, using
The side stomata 10 of 7 lower section of floating ball enters exocoel 9, then enters inner cavity 6 from the side stomata 10 above floating ball 7, then from exhaust outlet 8
Discharge, when there is crude oil in gas, floating ball 7 floats, and withstands exhaust outlet 8, and crude oil will not be ejected.The floating ball 7 is plastics
Material, valve ball are steel.
The pressure spring 3 of 2 upper end of valve ball of steel, for controlling the pressure opened, due to gravity and pressure spring active force, usually
State valve ball 2 is to block lower section connector 4 in bottom.When gas pressure reaches certain big in wellhead casing pipe, can open
Valve ball 2, gas passes through several through-holes 5 and enters inner cavity 6, then enters exocoel 9 by the side stomata 10 of lower position, and gas is again
Enter inner cavity 6 from the side stomata 10 of higher position around floating ball 7, is then discharged from exhaust outlet 8.After crude oil entrance, due to
7 density of floating ball is less than crude oil and blocks exhaust outlet 8 by crude oil top to the top, and this prevents sets to spray phenomenon.
