Description
Technical field
This utility model relates to field of oil drilling, particularly to a kind of drilling fluid leakage position measuring instrument.
Background technology
During oil gas drilling, wellbore stability is the problem being widely present.Its harm is huge, it will usually cause
The challenge of down-hole.Plugging operation it is critical only that leakage occur after, accurately determine the position of lost-circulation zone as early as possible, in order to and
Time take effective leaking-stopping measure, it is ensured that drilling well is normally carried out.But up to the present, the determination of leak position also the most more essence
True method, or there is limitation in some, is not suitable for carrying out the judgement of leak position in the case of complexity is missed.China is 20
Century 70 starts to develop drop ply measuring instrument, and these instruments are by mean of what fluid dynamic principle was developed mostly, it
When leakage being occurred, fluid flow-transfer becomes the displacement of diaphragm to measure, or using for reference turbine flowmeter measuring principle enters
Row flow measurement.The most just occurring in that the technology using multiple method complementary measurement leak position, accuracy has had and has carried more greatly
High.As the patent of Publication No. 102383784A discloses a kind of storage-type leaking layer position integrated measuring instrument, this instrument uses well
The comprehensive measuring methods such as temperature, noise and sound wave, measure to use downhole stored mode, utilize drilling rod to advance or cable is transferred,
Improve accuracy to a certain extent.The patent of Publication No. 101446194A discloses a kind of electromagnetic type leak-checking apparatus, uses
Drilling fluid flow velocity measured by ultrasonic sensor, uses electromagnetic method to measure formation characteristics simultaneously, and certainty of measurement is high, easy to operate.But
These methods still suffer from some problems, and the mode as used cable or drilling rod to advance after leakage measures, and exists certain
Risk, as cave-in easily causes lock of tool drilling, construction is got up the most more complicated；The most most of instruments need leaking
After mistake, carry out trip-out operation, enter instrument down and measure.Which not only adds the risk of well control, and cause and execute
The complexity of work and loaded down with trivial details.
Utility model content
The purpose of this utility model is the problem existed for prior art, it is provided that a kind of self-floating drilling fluid leakage location
Instrument, can be used for sentencing and knows the accurate location that leakage occurs.This utility model use self-floating measure pipe nipple to the pressure of absorption well section,
Flow and temperature measure and comprehensively analyze, and accurately draw loss horizon.This instrument can put in drilling rod after leakage occurs,
Measure after Gu Ding, then after being measured, float to well head and reclaim, can effectively avoid well control risk.
Principle of the present utility model is: after leakage occurs, and is put in drilling rod by measuring instrument pipe nipple, utilizes drilling fluid to promote,
It is connected with fixing pipe nipple, after fixing, absorption well section is measured, and data are stored, after being measured, recycle drilling fluid
Promoting measuring instrument pipe nipple to separate with fixing pipe nipple, measuring instrument pipe nipple floats to well head under floating drum effect, after taking out measuring instrument pipe nipple
Storage data can be read out, determine the accurate location of leakage.
The technical solution of the utility model is achieved in that
Self-floating drilling fluid leakage direction finder, including flow measuring sensor 5, pressure temperature measuring sensor 6 and data
Memorizer 7, wherein: flow measuring sensor 5, pressure temperature measuring sensor 6 and data storage 7 are sequentially connected with as overall group
After part, centralizer 4 and lower centralizer 8 on its two ends connect respectively, and upper centralizer 4 end connect float component 3, under hold up
The positive upper Self-locking joint 9 of device 8 end connection, is combined with fixing pipe nipple in upper Self-locking joint 9 end grafting, by propping up in fixing pipe nipple
Strut 10 is fixed with lower Self-locking joint 11, and lower Self-locking joint 11 constitutes grafting self-locking with upper Self-locking joint 9 and coordinates.
Such scheme also includes: in float component 3, and end is also associated with amortisseur 2 and anti-rams 1.
This utility model has the advantage that
1. use self-floating measuring instrument pipe nipple, drilling tool all need not be taken out well head, just can complete the survey to downhole parameters
Amount, it is possible to effectively reduce the risk of well control.
2. during wellbore construction, in drilling tool, there is no measuring instrument, it is possible to ensure the annular space of drilling tool, implementing blocking construction
Time, beneficially being smoothed out of bulky grain loss circulation material.Meanwhile, when decreasing wellbore construction, bit vibration is to surveying what instrument caused
Injury.
Accompanying drawing explanation
Fig. 1 is measuring instrument pipe nipple structural representation.Fig. 2 is fixing pipe nipple structural representation.
Detailed description of the invention
In conjunction with Fig. 1, Fig. 2 to judging that implementation process illustrates.Self-floating drilling fluid leakage direction finder by measuring instrument pipe nipple,
Fixing pipe nipple two parts composition.The composition of measuring instrument pipe nipple: anti-raming 1 is connected with amortisseur 2, amortisseur 2 and float component 3 phase
Even, float component 3 is connected with upper centralizer 4 assembly, and upper centralizer 4 is connected with flow measuring sensor 5, flow measuring sensor
5 are connected with pressure temperature measuring sensor 6, and pressure temperature measuring sensor 6 is connected with data storage 7, data storage 7 with
Lower centralizer 8 is connected, and lower centralizer 8 is connected with upper Self-locking joint 9.The fixing built-in fixing support bar 10 of pipe nipple and lower self-locking
Joint 11, both are connected.
The mode that float component uses many floating drum docking to be connected assembles, and can effectively ensure different drilling fluid density
Under, the buoyancy of floating drum meets requirement.Data storage comprises battery, after connecting battery, start measurement data is carried out storage and
Timing, is powered whole instrument simultaneously.Pressure temperature measuring sensor comprises pressure transducer and temperature sensor.Flow
Measure sensor and use acoustic wave flow meter.Centralizer all uses rubber centralizer up and down, is used for improving centralizer at high speed vibration
Under the conditions of life-span, ensure the docking of upper and lower self-locking joint simultaneously.
When self-floating drilling fluid leakage direction finder uses, first fixing pipe nipple is installed on nearly bit location, with drill set
Close under lower going-into-well.After leakage occurs, measuring instrument pipe nipple is put in drilling rod, connects turn on pump after kelly bar, utilize rushing of drilling fluid
Measuring instrument pipe nipple is docked by power in the fixing pipe nipple of nearly bit location, then anticipation absorption well section is carried out flow, temperature,
The measurement of pressure parameter also stores data.After being measured, then turn on pump, measuring instrument pipe nipple is unlocked with fixing pipe nipple and separates, survey
Amount instrument pipe nipple, under the effect of floating drum, floats to well head, then dismantles kelly bar, takes out measuring instrument pipe nipple, utilizes computer on ground
The software data to obtaining carry out integrated treatment, it is judged that the accurate location that leakage occurs.
