Description
Technical field
The present invention relates to technical field of petroleum extraction, more particularly to a kind of processing method of fine and close Oil/gas Well gas lock.
Background technology
The fine and close oil gas found in Ji in the Dark grey mud stone of beam deer depression SHAHEJIE FORMATION, oil shale, cream mud stone.Marl
Cranny development, bearing capacity is low, and oil gas is active, leakage easily occurs in work progress, after causing pressing crack construction, fracturing fluid can not return
Row, gaslift tubing flow displacement success rate are low.Need tubing pump of the tripping in gas anchor in well to carry out discharge opeing, recover the oil (gas), but often result in
Tubing pump gas lock.
Sun Shuan is published in the 10th phase in 2010《Petroleum machinery》On magazine " long plunger ring-sealing gas-tight sand-proof oil pump is ground
The deficiency of vapour lock, gas lock and sand card phenomenon is produced when the text of system " one for solving common oil-well pump at present, have developed a kind of new
The long plunger ring-sealing gas-tight sand-proof oil pump of type.The pump uses long-plunger short pump barrel structure, and its upper end is designed to that mechanical strong open and close is prevented
The fuel-displaced valve assembly of gas, seal section use and scrape sand ring, compensation becket and the spaced form sand control of nonmetallic ring.Daqing oil
The field test in field shows that the pump can work to high efficient and reliable in the oil well of various oil-gas ratioes, compared with common oil well pump,
Average pump efficiency improves 15%~20%, and average individual well pump detection period extends more than 90d.
Zhai Xiao east et al. is published in the 7th phase in 2011《Western mineral exploration engineering》On magazine " long-plunger gas prevention pump is in ancient city
The application and effect analysis in an oil field " text analyzes the gases affect problem of oil well pump with long plunger piston and adopted currently for the problem
The weak point of several measures taken, it is proposed that anti-gas lock cone valve type oil well pump, and describe design and the scene of the oil well pump
Test situation.Experiment shows that anti-gas lock cone valve type oil well pump can entirely prevent oil well pump gas lock, improves pumping efficiency of oil pump.If
It is used cooperatively with underground free gas separator and wellhead casing pipe valve discharging gas under certain pressure, more preferable effect will be obtained.
Zhang Chundong et al. is published in the 9th phase in 2005《Inner Mongol petrochemical industry》" the gas-tight in oil field development on magazine
The text of technology " one is directed to the oil reservoir development present situation of the gassiness blocks such as the administrative purifying in Shengli Oil Field Chun Liang oil recovery factories, great Lu lakes, Gaoqing,
Using oil well outlet gas lock mechanism as theoretical foundation, deploy the investigation to current oilfield gas-tight technology, with reference to pure
The reality and present situation of beam oil recovery factory gassiness block, the downhole tool with good gas-tight gas separation effect is preferably promoted, it is not only rich
Rich oil reservoir gas-tight technology, and the Efficient Development of the high and stable yields to improving our factory gassiness block has positive tribute
Offer.Using all kinds of 7 kinds of gas-tight instruments, implement 438 wells, as foundation, to be improved with the data that can be contrasted using gas-tight technology
Oil well individual well pump efficiency 23.6%, add up to increase 8760 tons of oil, achieve significant oil increasing effect.
These prevent the technology of gas lock in being exploited for conventional gas and oil, after the application of fine and close Oil/gas Well, the term of validity is short, fine and close
After Oil/gas Well gas lock, without effective solution.
The content of the invention
The purpose of the present invention is：The solution method of fine and close Oil/gas Well gas lock is provided, technical staff or operator are in well head
Just can solve the problems, such as gas lock, meet the normal production of fine and close Oil/gas Well, rate improves more than 50% when effective.The technical side
Case is as follows：
The embodiments of the invention provide a kind of processing method of fine and close Oil/gas Well gas lock, methods described includes：
The judgement of gas lock, when well head observes oil pressure gauge 9, back pressure meter 10 in oil pumper up-down stroke, the change feelings of pressure
Condition, if oil pressure gauge 9, the pointer of back pressure meter 10 do not change in oil pumper up-down stroke, there occurs gas lock for underground tubing pump；
After it is determined that gas lock occurs, the first step：Small with well head four-way 1 and gathering line 8 is closed by shaven head 12 to be connected
The 250 model production tree special valve 4 connect, in the case that oil pumper runs well, the change of the pressure of oil pressure gauge 9 is observed, works as oil pressure
When the pressure of table 9 is more than 10 pressure 0.5MPa~0.6MPa of back pressure meter, open with the small four-way 1 of well head and gathering line 8 by and
The still first 12 250 model production tree special valves 4 being connected；
