Description
Technical field
The invention belongs to oil field cleaning workover treatment technical field more particularly to a kind of workover treatment oil pipe and sucker rods
Closed on-line cleaning method.
Background technique
Oil well repairing operation acts the oil pipe, sucker rod surface adhesion has crude oil, wax stone, is generally steamed using boiler car high temperature
Vapour ground cleaning, it is time-consuming and laborious, and pollute environment.
In recent years, Some Domestic oil field utilizes cleaning equipment, and by installing cleaning device in well head, it is logical to establish hot wash circulation
Road carries out oil pipe bar washing and cleaning operation, but live bad adaptability." a kind of workover treatment as disclosed in patent No. CN105114035A
Oil pipe, sucker rod on-line cleaning technique " mainly using steam source device provide hot water, by wellhead cleaning device, screen casing or
The tools such as bushing pipe establish circulation in pit shaft, realize to oil pipe bar on-line cleaning operation.But the process scavenging period is long, nothing
Method cleaning tubing inner wall, while wax melting cannot be recycled effectively, fall into pit shaft pollution stratum, effect of field application is poor.
Summary of the invention
The present invention provides the closed on-line cleaning method of a kind of workover treatment oil pipe and sucker rod, the first purpose is to mention
For a kind of on-line cleaning method for realizing the closed cleaning of oil pipe bar inside and outside wall;The second purpose is to provide a kind of sump oil wax melting can be real
Shi Huishou reaches the on-line cleaning method of cleaning well workover.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of closed on-line cleaning method of workover treatment oil pipe and sucker rod, includes the following steps
Step 1: installation sucker rod cleaning apparatus
Production tree is dismantled first, acts polished rod, then sucker rod cleaning apparatus and sucker rod are successively installed in tubing hanger
Preventer, then closed cleaning vehicle is connect with sucker rod cleaning apparatus;
Step 2: cleaning sucker rod and Recycling of waste liquid
After the completion of step 1, shackle promotes sucker rod, starts the thorn in closed cleaning vehicle and washes pump, with closed cleaning vehicle
In cleansing medium thorn wash sucker rod, while the real-time Recycling of waste liquid of negative pressure recovery system or exhaust gas in closed cleaning vehicle;
Step 3: act sucker rod
After the completion of step 2, acts sucker rod and be emitted on the sucker rod is acted on beam hanger bridge, it is close to complete sucker rod
Close washing and cleaning operation;
Step 4: installation oil pipe cleaning device
After the completion of step 2, tubing hanger of dismantling successively installs ram preventer, oil pipe cleaning device and splashproof and receives oil
Box;Closed cleaning vehicle is connected with oil pipe cleaning device;
Step 5: cleaning tubing outer wall and Recycling of waste liquid
Oil pipe is promoted, starts the thorn in closed cleaning vehicle and washes pump, pierces washing oil pipe outer wall, while closed cleaning with cleansing medium
The real-time Recycling of waste liquid of negative pressure of vacuum recovery system or exhaust gas in vehicle;
Step 6: cleaning tubing inner wall and Recycling of waste liquid
After the completion of step 5, flowline and shackle are played, oil box is received with splashproof and embraces at tubing coupling, above mentions oil pipe to de-
Button, but do not propose that splashproof receives oil box, with the cleansing medium cleaning tubing inner wall in closed cleaning vehicle, while in closed cleaning vehicle
The real-time Recycling of waste liquid of negative pressure of vacuum recovery system or exhaust gas;
Step 7: flowline is played
After the completion of step 6, plays flowline and the oil pipe discharging will be acted on oil pipe bridge, the cleaning for completing oil pipe is made
Industry.
Cleansing medium in the step two, step 5 and step 6 is steam-hot aqueous medium.
Closed cleaning vehicle is connect by the step one with sucker rod cleaning apparatus, is by the high temperature and pressure of closed cleaning vehicle
Thorn wash system and negative pressure of vacuum recovery system respectively with sucker rod cleaning apparatus inlet and sucker rod cleaning apparatus recovery port phase
Connection, establishes wellhead cleaning channel.
The step is second is that controlling cleansing medium under conditions of temperature is 100~120 DEG C, pressure is 6~10MPa
The thorn for carrying out sucker rod is washed.
Closed cleaning vehicle is connected with oil pipe cleaning device in the step four, is to pierce the high temperature and pressure of closed cleaning vehicle
The first inlet for washing system is connected with oil pipe cleaning device inlet, and the high temperature and pressure thorn of closed cleaning vehicle washes the second of system
Inlet quickly connect injection head with oil pipe and is connected, recovery port and the oil pipe cleaning device recovery port phase of negative pressure of vacuum recovery system
Connection, oil pipe cleaning device recovery port and splashproof receive oil box;Oil pipe is quickly connected to injection head to be mounted in tubing coupling.
It is to control cleansing medium under conditions of temperature is 90~120 DEG C, pressure is 5~9MPa in the step five
Carry out the cleaning of oil-pipe external wall.
It is to control cleansing medium in the condition that temperature is 95~125 DEG C, pressure is 6~10MPa in the step six
The lower cleaning for carrying out tube inner wall.
The utility model has the advantages that
The present invention passes through installation sucker rod cleaning apparatus, cleaning sucker rod and Recycling of waste liquid, plays sucker rod, installation oil pipe out
Cleaning device, cleaning tubing outer wall and Recycling of waste liquid, cleaning tubing inner wall and Recycling of waste liquid and seven steps of flowline, use
High temperature and high pressure steam-hot aqueous medium is washed with the double action of high temperature wax melting using high pressure thorn to oil pipe bar surfaces externally and internally crude oil, knot
The closed cleaning of wax, the activity duration is short, and cleaning is more thorough, has realized sucker rod, oil pipe on-line synchronous operation.It is steamed using ground
Vapour, mating injection head combination, solve the problems, such as that the prior art can not clean tube inner wall.Utilize negative pressure of vacuum
Recovery system has prevented oil pipe bar operation wellhead splash.To operation process generate waste liquid all recycle, to stratum, ground without
Injury, is truly realized cleaning operation.The present invention is widely used, can meet screw pump, etc. drip-frees well cleaning workover treatment.
