Leakage is a urgent need to solve the problem in drilling well.Its danger and disaster is very large, but deals with very complicated, the technical scheme needing a large amount of human and material resources and be applicable to.Although leakage stopping technology is one of focus of numerous technician research always, constantly there is new techniques and methods to occur, for now, in Slot Handling process, still there is certain problem, make plugging effect unsatisfactory.The key of plugging operation determines the position of lost-circulation zone after being that leakage occurs as early as possible exactly, to take effective leaking-stopping measure in time, ensures that drilling well is normally carried out.But up to the present, the determination also comparatively not accurate method of leak position, or there is limitation in some, is not suitable for the judgement carrying out leak position in complexity leakage situation.China starts to develop drop ply measuring apparatus at 20 century 70s, these instruments are developed by means of fluid dynamic principle mostly, it otherwise when leakage being occurred, fluid flow-transfer becomes the displacement of diaphragm to measure, or using for reference turbine flowmeter measuring principle carries out flow measurement.
Occurred the technology of employing multiple method complementary measurement leak position in recent years, accuracy is greatly improved.As publication number be 102383784A patent discloses a kind of storage-type leaking layer position integrated measuring instrument, this instrument adopts the comprehensive measuring methods such as well temperature, noise and sound wave, measure to adopt downhole stored mode, utilize drilling rod propelling or cable to transfer, improve accuracy to a certain extent.Publication number be 101446194A patent discloses a kind of electromagnetic type leak-checking apparatus, adopt ultrasonic sensor to measure drilling fluid flow velocity, adopt electromagnetic method to measure formation characteristics, certainty of measurement is high, easy to operate simultaneously.But still there is following problem in these methods:
1, the poor accuracy determined of drop ply position, affects leak stopping success rate; And most of drop ply metering system simply can only provide the general location of drop ply, the information such as feature, type knowing leakage can not be sentenced, cause certain difficulty to next step blocking construction.
There is certain risk in the mode 2, adopting drilling rod to advance after leakage, as cave-in easily causes lock of tool drilling, and also more complicated of constructing;
3, most of appliance requires is after missing, and carries out trip-out operation, then enters instrument down and measures.Which not only adds the risk of well control, and cause the complexity of construction and loaded down with trivial details.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of drilling fluid leakage position-measurement device can sentencing type, feature and the particular location known leakage and occur in time.
The technical solution of the utility model is achieved in that

In such scheme: mozzle assembly is made up of mozzle and electromagnetic flowmeter; Pressure temperature measuring assembly is made up of down-hole pressure sensor and temperature pick up; Observing and controlling electronic building brick comprises DSP electronic control system, storage system and battery.
Upper and lower centralizer is rubber centralizer.
Principle of the present utility model is: the utility model device is installed on nearly bit location with the form of pipe nipple, before entering anticipation drop ply, with under drilling assembly lower going-into-well, resting state is in process is drilled in down-hole, after missing, carry out trip-out operation, can start when meeting and impose a condition in trip-out process, scanning survey is carried out to full well section, gathers pressure, flow and temperature data.Then on ground, data are carried out playback and explanation, and the position that synthetic determination leakage occurs.
The utility model tool has the following advantages:
1. adopt pressure, temperature, flow Three models to detect leakage and drop ply, be conducive to exclusive PCR factor, improve the accuracy of leak position judgement and the precision of drop ply measurement.
2. device is installed on nearly bit location with the form of pipe nipple, after missing, first need not trip out drilling tool and enter down measuring apparatus measurement again, but directly carry out trip-out operation, measure in trip-out process.Enter down the generation of the down hole problem that apparatus measures causes after avoiding trip-out again, saved simultaneously pull out of hole for one time and under enter time of instrument, decrease the well control risk in trip-out process.
3. pipe nipple is built with bypass valve, can the pressure of balance measuring device and well and flow, significantly can improve the certainty of measurement of borehole pressure and changes in flow rate.
