METHOD OF WELLS OPERATION WITH POSSIBILITY OF GAS OVERPRESSURE BYPASS, WELL LIQUID DISCONNECTION AND GAS SHUTDOWN BYPASS VALVE FOR ITS IMPLEMENTATION |
摘要 |
FIELD: oil and gas industry.SUBSTANCE: gas shutdown bypass valve comprises body, bush, float valve and casing secured by nuts. In body holes are made to connect the annulus with tubing internal cavity. In the casing holes are made for gas bypass. In bush through holes are made. In the body valve pairs are installed, they comprise seat and ball. In top part of the float valve the sealing bevels are made. The float valve seat has counter sealing bevels.EFFECT: increased efficiency of automatic disconnection of the oil-gas-liquid well fluid entering from annulus in gas shutdown bypass valve.2 cl, 1 dwg |
