Abstract
A well control discharge pipe line corollary device in the oil-gas well foam underbalance operation, namely a blowout sampling device includes a sampling pipe nipple 1, a sleeve pipe nipple 2, an elbow 3, a blowout pipe nipple 6, etc. The sleeve pipe nipple 2 is connected with the sampling pipe nipple 1 and a lower flange 5 is connected with the sleeve pipe nipple 2 through a flange pipe nipple 4. An upper flange 7 is connected with the blowout pipe nipple 6. The elbow 3 is connected with the blowout pipe nipple 6. The sleeve pipe nipple 2 is provided with a gas logging pipe nipple 10. The device can carry through rock debris sampling operation instantly, ensure the rock debris to be successfully led out with the foam discharge under a high flow speed and reduce the blowout pipeline length. The elbow design of a blowout nozzle does not only avoid the problem of annulus pressure increasing from the discharge pipeline connecting position to an wellhead, the blowout pipeline can also ensure to pump the wellhead during the period of making a connection to lead the foam to be discharged continuously. And during the period that the wellhead is opened, the device provides pumping on the fluid invaded in the wellhead and ensure the security of drill floor operating personnel. The sleeve pipe nipple on the device is provided with the gas logging pipe nipple and can be used for gasing logging service during a drilling process.
Description
The utility model relates to well control discharge pipe line corollary equipment in the operation of a kind of oil gas well foam underbalanced drilling, specifically, is a kind of open flow sampler.
At present, in the job execution of oil gas well foam underbalanced drilling, there be not special supporting open flow or sampler.The open flow operation often adopts three-port structure to link to each other with discharge pipe line, or in addition with adopting a cover pipeline open flow to the discharging pond, can increase the pressure of threeway junction discharge pipe line when adopting the former to make up a joint open flow to the well head annular space, be unfavorable for that foam discharges continuously, and during well head is opened, increase rig floor staff's production safety hidden danger because of pernicious gas effusion possible in the pit shaft; Adopt the latter can not avoid the problems referred to above, still there is the harm of pernicious gas effusion in the rig floor operating personnel during well head is opened, and far away because of the discharging pond, has also increased the length of pipeline greatly.The landwaste sampling also adopts three-port structure to pick out valve from discharge pipe line at first, but in fact the foam high flow rate produces negative pressure at valve export and makes landwaste to take out when creeping into, and, because of the timely froth breaking of foam in the discharging pond, go to discharge the pond fish for rock sample also very the difficulty, can't guarantee to fish for timely and accurately rock sample, the discharge pipe line ejiction opening is especially owing to foam drainage speed height, impact Fang Qiang, can't fish for landwaste at its end at all, directly influence sieve residue log, formation lithology is estimated in the geology man analysis caused very big difficulty.
The purpose of this utility model is to provide a kind of open flow operation that is applicable to when the landwaste in the oil gas well under balance pressure drilling process is taken a sample and made up a joint, can reduce the length of relief line, guarantee the open flow sampler that landwaste is derived under with the foam drainage high velocity stream smoothly.
The utility model is achieved in that and comprises sampling pipe nipple 1, casing nipple 2, elbow 3, flange spool 4, lower flange 5, open flow pipe nipple 6, upper flange 7, bolt 8, nut 9, gas survey pipe nipple 10, casing nipple 2 is connected with sampling pipe nipple 1, lower flange 5 is connected with casing nipple 2 by flange spool 4, upper flange 7 joins with open flow pipe nipple 6, elbow 3 is connected with open flow pipe nipple 6, has gas to survey pipe nipple 10 on the casing nipple 2.
The utility model also adopts following technical scheme:
Sampling pipe nipple 1 turns forward and stretches into the discharge flow path center and be welded on the casing nipple 2.
Sampling pipe nipple 1 is spent greater than 0 with the angle that casing nipple 2 tilts.
Lower flange 5 is welded on the casing nipple 2 by flange spool 4.
The bottom of elbow 3 and open flow pipe nipple 6 is with being threaded.
The emission direction of elbow 3 is consistent with emission direction.
Gas is surveyed pipe nipple 10 and is communicated with casing nipple 2 welding and with discharge flow path.
Advantage of the present utility model is: stretch into the interior sampling pipe nipple 1 of discharge flow path owing to adopt to turn forward, in oil gas well under balance pressure drilling process, can carry out landwaste sampling operation immediately, guarantee that landwaste derives under with the foam drainage high flow rate smoothly, this device is installed in the middle of the discharge pipe line, can reduce the length of relief line, the problem that the elbow design of open flow mouth has not only avoided the discharge pipe line junction to increase to the well head annular pressure, relief line also can guarantee during making up a joint well head to be formed suction, foam can be discharged continuously, and during well head is opened, provide invading the suction of fluid in the well, guarantee rig floor operating personnel safety, casing nipple on this device is provided with gas and surveys pipe nipple, can be used for gas detection logging service in the drilling process.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Mainly containing sampling and open flow two parts forms, sampling pipe nipple 1 certain angle that turns forward stretches to the discharge flow path center, be welded on the casing nipple 2 and constitute sampling part, sampling pipe nipple 1 outer end can connect valve and control the sampling operation, the open flow part is by open flow pipe nipple 6, lower flange 5, upper flange 7, bolt 8, nut 9, elbow 3, flange spool 4 is formed, lower flange 5 is welded on the casing nipple 2 by flange spool 4, upper flange 7 welds mutually with open flow pipe nipple 6, flange part adopts bolt 8 to be connected with nut 9, elbow 3 usefulness are threaded in the bottom of open flow pipe nipple 6, the emission direction of elbow 3 is consistent with emission direction, in addition, on casing nipple 2, also be welded with the gas that communicates with discharge flow path and survey pipe nipple 10, in the open flow sampler, sampling pipe nipple 1, casing nipple 2, flange spool 4 and open flow pipe nipple 6 all adopt the API sleeve pipe with foam operation discharge pipe line equality strength, oil pipe, or other suitable material of performance.
