Abstract
The utility model relates to a drainage device at an operation wellhead; a right seal body and a left seal body are connected through a loose leaf and are a hollow cylinder when being folded; a drainage port is arranged at the middle part of the left seal body, the lower end of a fixing rod is fixed on a big cross joint at the wellhead to keep the fixing rod near the wellhead; when an oil pipe with oil is lifted to the wellhead, the left seal body and the right seal body are buckled on the oil pipe, a tubing coupling is arranged at a large diameter section of the cylinder at the middle part to buckle a locking catch, so that the left seal body and the right seal body are combined to form the cylinder, the oil pipe above the tubing coupling is sealed by small inner diameter sections at the two ends of the cylinder; the oil pipe is reversely rotated and is then slightly lifted after a connecting screw thread is dismantled; and the oil in the oil pipe above the tubing coupling is drained from the dismantling part to a sleeve tube through a liquid outlet on the right seal body. When an oil well stops operation, an underground oil drainage device can not drain oil, and the drainage device is arranged at the wellhead, so that the oil in the oil pipe can be drained to the well at the wellhead and can not spray on the workers, and brings no pollution to the environment.
Description
Technical field
The utility model belongs to the equipment that the oil well operation field is used, and is a kind of operation well head drain pump.
Background technology
Bleeder kind in the pumping pipe string of oil field is a lot, but all is mounted on the downhole pump.Open the draining hole when effect of bleeder is operation, oil pipe on the pump is communicated with sleeve pipe, make profit current drainage in the oil pipe on the pump in sleeve pipe.Malfunctioning and the situation that can't draining of work all appearred in various down-holes bleeder, and when the malfunctioning not draining of bleeder, the profit on the oil well pump in the oil pipe will be ejected into ground, causes environment pollution.
Summary of the invention
The purpose of this utility model is a kind of operation well head drain pump of design, when the down-hole bleeder is malfunctioning, uses this operation well head drain pump to avoid profit to be ejected into ground and to cause environment pollution with the profit in the oil pipe in well head current drainage Hui Jing.
The purpose of this utility model is achieved in that and comprises right seal, left seal, operation handlebar, snap close, fixed bar, leakage fluid dram, right seal, left seal are connected by loose-leaf, right seal, left seal close up the back and are hollow cylinder, the two ends internal diameter is little, the middle part internal diameter is big, at left seal middle part leakage fluid dram is installed, fixing snap close on right seal, the left seal, be symmetrically welded operation handlebar on right seal, the left seal, fixed bar is fixed on the left seal.
The beneficial effects of the utility model are: when oil well stopping production operation, the down-hole bleeder can not draining, and this operation well head drain pump is installed in well head, just can make profit in the oil pipe in well head current drainage Hui Jing, does not spray on one's body the operating worker, and is free from environmental pollution.
Description of drawings
Fig. 1 is an assembling front elevation drawing of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1 embodiment of the present utility model is described.
Embodiment of the present utility model comprises right seal 1, left seal 2, operation handlebar 3, snap close 4, fixed bar 5, leakage fluid dram 6, right seal 1, left seal 2 are connected by loose-leaf, right seal 1, left seal 2 close up the back and are hollow cylinder, the two ends internal diameter is little, the middle part internal diameter is big, and leakage fluid dram 6 is installed at left seal 2 middle parts, fixing snap close 4 on right seal 1, the left seal 2, be symmetrically welded operation handlebar 3 on right seal 1, the left seal 2, fixed bar 5 is fixed on the left seal 2.
Fixed bar 5 lower ends are through on the well head big four during use, be fixed on the well head big four by two nuts, it is near the well head, after the oil pipe that has profit rises to well head, spur the operation handlebar on the right seal 1, make right seal 1, on two oil pipes under left side seal 2 is buckled on the tubing coupling, tubing coupling is in right seal 1, left side seal 2 middle part enlarged diameter sections, fasten snap close 4, make right seal 1, left side seal 2 synthetic cylinders, internal diameter section small in ends seals up the oil pipe of criticizing on the tubing coupling, an oil pipe on the counter-rotating tubing coupling, carry oil pipe on slightly after connecting thread dismantled, the profit in that root oil pipe on the tubing coupling flow in the sleeve pipe from dismantling the liquid outlet 6 of current drainage on right seal 1.
