Abstract
The utility model provides a lost circulation detection device, including cable, cable joint, flow measurement nipple joint and ressure measurement nipple joint. The cable links to each other with cable joint, and cable joint links to each other with the flow measurement nipple joint, and the flow measurement nipple joint links to each other with the ressure measurement nipple joint, two drilling fluid business turn over porees around the flow measurement nipple joint has, the ressure measurement nipple joint has the slot. The device adopts power supply through cable and transmitting data, utilizes high accuracy pressure sensor and flowmeter to confirm missing the level. Have simple easily operation, the reliability is high, it is safe relatively in the pit, do not exist and collapse when taking place with the small -size leakage of well control risk, the measurement of missing the position that can be fine.
Description
Technical field
The utility model relates to a kind of dropout detection device, particularly a kind of oil drilling drilling fluid leakage checkout gear.
Background technology
Leakage is the major engineering problems of the domestic and international oil exploration of puzzlement, exploitation always, fails so far to solve completely.The key of process leakage is to determine drop ply position, therefore, accurately judges that drop ply position is the technical barrier that first will solve in leakage stopping technology.Abroad as far back as the fifties in last century with regard to start to use hydrodynamics method and by the method for instrument test to study drop ply character.Many employing instrument test method determination drop ply positions at present, as sonic test instrument, well temperature testing instrument, eddy current tester, radioactive tracer, Noise Method, sensor measurement method etc.At present, external extensive use be temperature and Noise Method, also other some drop ply measuring techniques of positive develop actively, comprising: hot line well logging, the well logging of pressure frequency converter, automatically side leakage technology etc.These technology are not perfect, and all these are measured all needs a considerable amount of drilling fluid to pump in well and stratum of bleeding, sometimes also very difficult to the explanation of measurement result.
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.But part Instrument Design is too complicated, and operation sequence is loaded down with trivial details, poor reliability, and data redundancy is poor.Comparatively safe for down-hole, there is not the small-sized leakage of caving in well control risk, be applicable to adopting some to be simply easy to operation, the instrument that reliability is high is measured.
Summary of the invention
The purpose of this utility model is that the Instrument Design existed for prior art is complicated, operation sequence is loaded down with trivial details, the problem of reliability and data redundancy difference, provides a kind of leakage checkout gear being simply easy to operate, reliability is high.
For the attainment of one's purpose, the technical solution of the utility model is achieved in that
A kind of leakage checkout gear comprises cable, cable connector, flow measurement pipe nipple and pressure measxurement pipe nipple.Cable is connected with cable connector, and cable connector is connected with flow measurement pipe nipple, and flow measurement pipe nipple is connected with pressure measxurement pipe nipple, and flow measurement pipe nipple has former and later two drilling fluids to pass in and out duct; Pressure measxurement pipe nipple is with groove.
In order to improve leakage checkout gear smooth and easy enter well, pressure measxurement pipe nipple outer end connect seeker.
A when leakage checkout gear uses, the mode adopting cable to transfer puts into down-hole instrument, carries lowering operation on carrying out for barefoot interval, repeatedly measure, and according to the data analysis comparison that cable is uploaded, determine that position occurs in leakage, then, extract instrument.
The utility model adopts cable power supply and transmission data, and utilize high-precision pressure sensor and flow meter to determine loss horizon, tool has the following advantages:
1. comparatively safe for down-hole, there is not the small-sized leakage of caving in well control risk, this device has simple to operate, that reliability is high advantage.
2. adopt pressure and flow two kinds of modes to carry out analyses and comparison data, certainty of measurement is higher.
3. instrument adopt cable transmission data and under put and carry, structure is simple, is easy to maintenance, advantage of lower cost.
Accompanying drawing explanation
Fig. 1 is leakage structure of the detecting device schematic diagram.
Detailed description of the invention
Composition graphs 1 pair of measurement mechanism implementation process is described.Cable 1 is connected with cable connector 2, and cable connector 2 is connected with flow measurement pipe nipple 3, and flow measurement pipe nipple 3 is connected with pressure measxurement pipe nipple 4, and pressure measxurement pipe nipple 4 is connected with seeker 5.
Leakage occurs wait, stube cable and instrument, utilize cable that instrument is put into down-hole, carries lowering operation, repeatedly measure for barefoot interval on carrying out, and according to the data analysis comparison that cable is uploaded, determine that position occurs in leakage, extract instrument then.
