Background technology
At present, along with the development of technology, the cluster well development technique is low because of investing, floor space is little, management point is few etc., and many advantages are popularized in an all-round way in oilfield construction.Cluster well is promptly built several mouthfuls of oil wells in 1 well site, is generally 3～5 mouthfuls, and well group output is high.It is through to multiple modes such as oil well perforation, tubing flow displacement, induced flow that the well site formation testing is gone into operation, and makes the fluid in the stratum get into pit shaft, flows out ground.And in this process, obtain the data such as pressure variation in the character of formation fluid, various fluid-withdrawal rate, strata pressure and the process fluid flow; And through the analysis of these data and the various physical parameters on processing acquisition stratum; The stratum is estimated, and prepared for oil well crude oil gets into surface technology flow process input ordinary production state.
Before the oil well access process, it is 20～30m that liquid measure is discharged in well site formation testing operation operation
3Cluster well field formation testing is at present gone into operation and is adopted open flow process; The liquid that the operation formation testing produces directly enters interim contaminated-oil basin or horizontal fuel tank; Associated gas directly discharges the entering atmosphere; There was certain disaster hidden-trouble in the generation jet fluid when particularly at present the pumping discharge opeing was with the discharge opeing of operation open flow in the activities.
The utility model content
The purpose of the utility model is: a kind of cluster well field device that airtight formation testing is gone into operation is provided; Eliminated cluster well field, oil field before not being connected into flow process; The disaster hidden-trouble of produced fluid improves oil-gas closed rate when pumping discharge opeing and the discharge opeing of operation open flow, to reach the reduction security risk.
The technical scheme that the utility model adopts is: the device that the airtight formation testing in cluster well field is gone into operation comprises that each well recovery tree 1, the wellhead assembly 2, first in the cluster well group has lining fire hose 3, sledge to adorn airtight eliminator 4 and fuel reserve tank 5; It is characterized in that: the outlet of well recovery tree 1 connects the throttling of wellhead assembly 2 by atmospheric valve 7, and throttling is by the tube tooth interface 6 of the other end connection wellhead assembly 2 of atmospheric valve 7, and tube tooth interface 6 connects first has lining fire hose 3; First has the other end of lining fire hose 3 to connect the inlet that sledge is adorned airtight eliminator 4; Eliminator blow-down pipe 9 is arranged at the top that sledge is adorned airtight eliminator 4; The bottom that sledge is adorned airtight eliminator 4 is connected with eliminator blowdown pipeline 8 and backwash pipeline 10; The oil export that sledge is adorned airtight eliminator 4 is connected with second has lining fire hose 14, the second to have the other end of lining fire hose 14 to connect the inlet of fuel reserve tank 5; Fuel reserve tank 5 is connected with fuel reserve tank blow-down pipe 11, fuel reserve tank entrucking pipeline 12 and fuel reserve tank blowdown pipeline 13.
The course of work of the device that the airtight formation testing in summary cluster well field is gone into operation.Consult Fig. 1.When formation testing or operation; The gas mixture that each well recovery is set 1 extraction gets into wellhead assembly 2; Have lining fire hose 3 to get into sledges through first fast and adorn airtight eliminator 4, have lining fire hose 14 to get into fuel reserve tanks 5 through separating back crude oil through second, sledge is adorned airtight eliminator 4 isolated associated gases and is drained into through blow-down pipe 9 and release flare; Sledge is adorned airtight eliminator 4 also can carry out backwash through backwash pipeline 10; Sewage drains into the well site sewage reservoir through blowdown pipeline 8, and fuel reserve tank 5, drains into gas through fuel reserve tank blow-down pipe 11 and to release flare the oil article vehicle outward transport through fuel reserve tank entrucking pipeline 12; Through fuel reserve tank blowdown pipeline 13 sewage in the fuel reserve tank 5 is drained into the well site sewage reservoir.
The beneficial effect of the utility model: the device that the airtight formation testing in the utility model cluster well field is gone into operation; Can realize oily buffering, gas-liquid separating function, backwashing function; Can realize that oil gas totally-enclosed collection is defeated, the disaster hidden-trouble of output jet fluid when having reduced pumping discharge opeing and the discharge opeing of operation open flow in the formation testing operation process.
