Description
Technical field
The present invention relates to oilfield pumping well production technique fields, and in particular to a kind of oil pumping machine well head oil collecting system and makes
Use method.
Background technique
At present oil field often with pumping unit exploit well head during there are many deficiencies, being operated first employee cannot intuitively sentence
Disconnected oil well liquid output situation, need to be built the pressure judgement by switch gate, and the operating time is long, and sample time is long, and regular sampling need to take three times
It is good, it at least needs to switch back-pressure gate and sampling gate three times, if oil pipe gas is big or winter oil is thick, sampling number is more, until
5-10 minutes are needed less, and sampling, emptying generation dead oil are more.Each well generates half barrel or so, takes Polywoven Bag to recycle, mistake
There is certain environmentally friendly risk in journey.Common Well head flow path development builds the pressure, samples that there are risk of leakage.Because regular development takes
Sample, build the pressure operation, and switch back-pressure gate is frequent, and gate airtight and watertight padding is be easy to cause to damage, and causes to pierce danger of leaking out, while also increasing
Replace the production cost of gate.Oil well leakage can generate reverse irrigation and cause production loss, and the leakage of down-hole pump valve is serious, in system its
His produced liquid in oil well amount can flow backward to leakage pit shaft, and website yield is caused to be mutated and cannot find to dispose in time.Polished rod fracture or
Wellhead packing box thorn leakage is serious, and entire oil collecting system liquid measure returns to packing box, causes blowout that cannot control in time.Therefore it is directed to
During above-mentioned existing pumping unit exploitation well head there are the problem of, first propose a kind of oil pumping machine well head oil collecting system and use
Method.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, a kind of oil pumping machine well head oil collecting system and application method are provided, it is main
Solve following problems:

8. a kind of oil pumping machine well head oil collecting system according to claim 1, it is characterized in that: first trip nonyl (6)
Internal diameter is that DN50mm swims nonyl, and the internal diameter of production gate (3) is DN50mm gate, and the internal diameter of the sampling gate (4) is DN15mm
Gate.
9. a kind of application method of oil pumping machine well head oil collecting system includes a kind of pumping unit of any one described in claim 1-9
Well head oil collecting system, it is characterized in that: the following steps are included:
Step 1: it opens pumpingh well and carries out oil pumping exhaust, petroleum enters delivery pipeline (15) by oil pumping machine well head (2), then
Enter oil gathering station by flow line, natural gas carries out outlet by natural gas exhaust line (16)；
Step 2: opening production gate (3) on the basis of step 1, and petroleum enters delivery pipeline from oil pumping machine well head (2)
(15) in, then petroleum passes sequentially through first pressure gauge (5), the first trip nonyl (6) and single flow check valve (7) into flow line,
When needing to measure the discharge capacity of single well, the back pressure mixing valve (10) in mixing delivery pipeline (19) is closed, opens single amount row
Back pressure list amount valve (11) on oil pipeline (18) allows petroleum to enter oil gathering station by single measure delivery pipeline (18), works as multiple wells
It is fuel-displaced simultaneously to oil gathering station when, close the back pressure list amount valve (11) on single amount delivery pipeline (18), open mixing delivery pipeline
(19) the back pressure mixing valve (10) on makes well extraction petroleum blending by mixing delivery pipeline (19) and other oil wells
Oil pipeline parallel connection enters oil gathering station.
Step 3: sampling lock when needing to carry out petroleum sampling on the basis of step 2, directly in opening sampling line (20)
Door (4) is sampled, and is directly closed after sampling sampling gate (4), and by single flow check valve (7) entrance front-end pipeline
The first pressure gauge (5) of connection and single flow check valve (7) export the pressure judgement of the second pressure gauge (8) connected on the pipeline of rear end
Oil well liquid output situation.
Step 4: on the basis of step 3 when needing pipeline failure to check, closing production gate (3), back pressure list amount valve
(11) and back pressure mixing valve (10) the emptying gate (9) on blow-down pipe (17), is then opened, entire delivery pipeline (15) are made
Interior petroleum empties, then in the malfunction elimination for carrying out entire pipeline.
