Description
Technical field
The utility model belongs to flow switch technical field, and in particular to a kind of novel flow rate for small size pulser
Switch.
Background technique
It is known as directed drilling along the boring method that the well track being pre-designed is bored up to target zone.Wireless drilling well logging system
It unites abbreviation MWD (MeasureWhileDrilling), is the accurate master tool of petroleum drilling and mining directed drilling operation, underground orientation
Precision, the reliability of detection are that the technology of well logging guarantees.MWD instrument string generally by mud pulse generator, battery component,
Inserting tube three parts composition.MWD instrument string generally can be with integral installation inside non-magnetic drilling tool, can also be integrally out of non-magnetic drilling tool
Extraction.For oil drilling with the intensification of drilling depth, wellbore is smaller and smaller, and down-hole equipment size includes internal diameter (slurry channel)
Also smaller and smaller.Common well-drilling borehole size has 17.5 inches, 13.125 inches, 8.5 inches, 6 inches of several, non-magnetic drilling tools
Outer diameter generally has 8.5 inches, 6.75 inches, 4.75 inches.Present document relates to extra small wellbore refer to 4.125~4.5 inches super
Slim-hole, non-magnetic drilling tool outer diameter at this time only have 3.125~3.5 inches.Under normal conditions, slurry pulsator generator is to sit
It is put into inside non-magnetic drilling tool, easily can install and remove at the scene, but in the construction of this extra small wellbore, due to space office
Limit, the head portion of mud pulse generator and hangs drilling tool without magnetcisuspension and is made as integrated, this has resulted in mud-pulse generation
Device easily can not be installed and be removed at the scene.It is surveyed so as to cause the percussion that can not carry out impulse generator flow switch at the scene
Examination (this when of flow switch is hung inside drilling tool in no magnetcisuspension, can not be contacted and be tapped), can not also download pulse generation
The data of device.
Utility model content
The purpose of this utility model is that: a kind of novel flow rate switch for small size pulser is provided, it is existing to solve
Some flow switches can not carry out the problem of ground taps test at the scene.
To achieve the goals above, the technical solution adopted in the utility model are as follows: provide a kind of for small size pulse hair
The novel flow rate switch of raw device, including control circuit board, pressure sensor, upper connector and lower connector, control circuit board point
It is not connect with pressure sensor and lower connector, upper connector is connected with lower connector.
Further, the model FLOWSTATPCBPN60617-010-HT of control circuit board, the model of pressure sensor
PIEZOPN60505, the model UPCON22PN81109 of upper connector, the model DOWNCONPN81108 of lower connector.
Further, 1 pin of control circuit board is connect with 21 pins of the lower connector, 2 pins of control circuit board
It is connect with 9 pins of the lower connector, 3 pins of control circuit board and 22 pins of lower connector connect, control circuit board
4 pins and 10 pins of lower connector connect, 2 pins of 5 pins of control circuit board and lower connector connect, control circuit
6 pins of plate are connect with pressure sensor, and 7 pins of control circuit board are connect with pressure sensor.
Further, 1 pin of upper connector, 2 pins, 3 pins, 4 pins, 5 pins, 6 pins, 7 pins, 8 pins, 21 pipes
1 pin of foot and 22 pins and lower connector, 2 pins, 3 pins, 4 pins, 5 pins, 6 pins, 7 pins, 8 pins, 21 pins
It connects one to one with 22 pins.
Further, the Aviation Connector at the utility model both ends is upper end pin end and lower end female connector.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
1. solving the problems, such as that small size impulse generator can not do functional test at the scene.
2. solving the problems, such as that small size impulse generator can not replace flow switch at the scene.
3. solving the problems, such as that small size impulse generator can not downloading data at the scene.
