Embodiment:
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
The unpowered oil rig of a kind of plunger type, be installed on pumping unit walking beam 1 below, there is connecting rod 2 to be hinged with pumping unit walking beam 1, connecting rod 2 belows and pump housing plunger 3 are hinged, five seal rings 20, seal ring 21, seal ring 22 are arranged between the plunger 3 of the pump housing and the pump barrel 19, and the bottom of pump barrel 19 is equipped with safety valve 18; Two transport pipe 4 that pump barrel 19 belows are communicated with, wherein oil-feed transport pipe 4 is equipped with import one-way valve 17, gate valve 16 and well head gate valve 12 successively from pump barrel 19 to well head 11, between well head gate valve 12 and gate valve 16, there is threeway to be connected, ball valve 14 and pressure gauge 15 are installed successively, there is threeway to be connected between well head gate valve 12 and the oily main line gate valve 10, ball valve 13 is installed, and oily main line gate valve 10 communicates with oily main line 9; Fuel-displaced transport pipe 4 is equipped with outlet one-way valve 5 and gate valve 8 successively from pump barrel 19 to oily main line 9, has a threeway to be connected between outlet one-way valve 5 and the gate valve 8, and ball valve 7 and pressure gauge 6 are installed.
The seal ring 20 of the top is the J type, and middle three seal rings 21 be the height lip, and the seal ring 22 below is an O shape, and the safety valve 18 of pump barrel 19 bottoms is connected with well head 11.
At first close oil pipeline gate valve 10 before the start, open well head gate valve 12 and gate valve 16 and gate valve 8, first-class pressure gauge 6 and pressure gauge 15 are closed Sampling ball valve 13, then starting up's pump work.When pumping unit is up, carry on pumping unit walking beam 1 drivening rod 2, the fluid in the well head is inhaled in the pump housing through well head gate valve 12, gate valve 16, import one-way valve 17, at this moment wellhead back pressure very little (0.1-0.2Mpa), during the up arrival of pumping unit dead point, oil-absorbing process is finished.When pumping unit is descending, pumping unit walking beam 1 drivening rod 2 presses down, liquid in the plunger 3 compression pump housings, import one-way valve 17 is closed, and outlet one-way valve 5 is opened, fluid is through outlet one-way valve 5, gate valve 8, be pressed in the oily main line 9 in the pump housing, to-and-fro motion like this reduces the leakage that wellhead back pressure causes, thereby increase liquid synergy, improve crude output.
