Description
Technical field
The utility model relates to Techniques for super heavy oil recovery field, in particular to a kind of well head tapping equipment and SAGD dual horizontal well of SAGD producing well.
Background technology
In oil exploitation technology, a large amount of natural gases be dissolved under HTHP in stratigraphic oil pool are called solution gas.In crude oil production, along with fluid enters producing well, pressure reduces gradually, when crude oil pressure is lower than saturation pressure, solution gas is just separated into free gas gradually from crude oil, and slowly expands, until depart from crude oil to enter oil casing annular space, this part gas is exactly casing gas.If sheath gas pressure is too high, producing fluid level will be made to decline, producing pressure differential reduces, and affects pump efficiency, also can occur " gas lock " time serious, oil well pump cannot normally be worked.
In crude oil production, press through height to prevent producing well inner sleeve and cause the too low phenomenon with there is oil well pump " gas lock " of submergence, the method generally adopted is casing gas discharging.Also there is this problem after terminating to proceed to machine pumping product in Xinjiang Oilfield super-viscous oil SAGD producing well cyclic preheat: in down-hole along with the expansion of vapor chamber, reservoir temperature raises, and hydrogen sulfide gas is separated.Hydrogen sulfide gas is assembled in oil well casing, and a large amount of stink damp is known from experience and accelerated down-hole facility corrosion, also likely causes down-hole string hydrogen embrittlement to break the generation of de-phenomenon.Guarantee that SAGD producing well is normally produced, necessary regularly relief sleeve gas, reduces sulfureted hydrogen gas concentration in sleeve pipe.
