Description
Technical Field
The utility model belongs to the technical field of instrument in the pit, in particular to an intelligent water injection mandrel for meticulous layering water injection in oil field.
Background
After the oil field is exploited to the middle or later period, the crude oil yield is generally ensured by injecting water or polymer into the stratum for oil displacement. The injection well layered survey and adjustment process is popularized and implemented in oil fields for many years, and plays a significant role in improving the economic benefit of the oil fields.
The water injection well generally divides into a plurality of horizons, and accurate control each layer water injection volume is the key of guaranteeing the output. At present, the oil field is mainly put into a well by adopting a direct-reading type seal device to seal each layer, and is put into the well by adopting a direct-reading type water quantity adjusting device to adjust the water injection quantity of each layer; the flow, temperature, water injection pressure, formation pressure and the like are measured by a direct-reading instrument. The seal checking and testing needs the well testing vehicle to go back and forth the well site for many times, the instrument is put into the well for many times, and the injection allocation requirement can be met only by repeatedly adjusting all the layers during testing and testing. The seal checking, the measurement and the adjustment consume a large amount of manpower and material resources, the efficiency is low, the labor intensity is high, and the risk that the shaft of the instrument is blocked and the like exists. The cable testing and adjusting can not carry out long-time real-time monitoring and control, and only can monitor the instantaneous injection amount; the water absorption change of each layer cannot be reflected in real time; when the water injection pressure or the stratum pressure changes to cause the change of the water injection quantity, the regulation can not be carried out in time when the water injection is unqualified. The method based on manual logging and adjustment has the defects of low measuring and adjusting efficiency, large influence of natural environment on field operation, high labor cost and the like.
At present, intelligent layered water injection is developed in oil fields, and the layered testing and debugging process of an injection well is upgraded to unmanned and full-automatic intelligent testing and debugging, so that the process becomes the development trend of the current industry. The intelligent water distributor is the key, and the main problems of the underground intelligent water distributor are that the diameter phi 42 of a central flow passage needs to be reserved, and flow measurement and regulation, pressure and temperature monitoring and the like are realized in a limited structural space.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a intelligent water distributor is provided, it can guarantee that the center overflows the passageway diameter and uses water distributor central channel size the same with current, can realize flow measure and regulate and temperature pressure monitoring simultaneously.
In order to solve the technical problem, the utility model discloses the technical solution who adopts is:
the utility model provides an intelligence water injection mandrel, its characterized in that, it includes: the device comprises a cable joint, a water distributor joint, a connecting threaded sleeve, a flow testing unit, a water distributor body, a circuit board assembly, an O-shaped sealing ring and a guide pipe; the water distributor joint is connected with the water distributor body through a connecting threaded sleeve, the water distributor joint is coaxial with an eccentric hole of the water distributor body, the water distributor joint is aligned and screwed with the left end and the right end of the water distributor body, a central channel of the intelligent water distributor is sealed through an eccentric step shaft hole, an O-shaped sealing ring ensures sealing performance, and a guide pipe is used for guiding during assembly; a sealing space formed between the central eccentric sealing shaft and the connecting threaded sleeve is used for installing a flow testing unit and a circuit board assembly; the cable joint is mounted on the water distributor joint.
The utility model discloses an intelligence water injection mandrel has following characteristics: 1. the intelligent water distributor body is integrally designed, the structure is simpler, the strength is high, the pressure-resistant requirement is met, the reliability is high after long-term use, and the forward and reverse threaded connection of the movable blade meets the eccentric assembly requirement. 2. The device is compatible with the structure of the original water distributor, the structure of the tubular column is not changed, and the use of other logging and well testing instruments is not influenced.

Detailed Description
The present invention will be described in further detail with reference to specific embodiments, but these examples are only illustrative and do not limit the scope of the present invention.
An intelligent water distributor, comprising: the device comprises a cable joint (1), a water distributor joint (2), a connecting threaded sleeve (3), a flow testing unit (4), a water distributor body (5), a circuit board assembly (6), an O-shaped sealing ring (7) and a guide pipe (8).
The diameter of the central channel of the intelligent water distributor is 46mm, the size of the central channel of the intelligent water distributor is the same as that of the central channel of the currently used water distributor, and the central channel of the intelligent water distributor is used as a flow passage and other well logging and testing instruments, so that compatibility is guaranteed. The central channel, which has a diameter of 46mm, is arranged eccentrically, due to the structural installation space requirements. The water distributor connector (2) is connected with the water distributor body (5) through the connecting threaded sleeve (3), the connecting threaded sleeve (3) is positive and negative threads, the positive and negative threads are connected in a loose-blade nut mode, two eccentric holes of the two parts are coaxial when the two parts are screwed, the two ends of the water distributor connector (2) and the water distributor body (5) are aligned and screwed, and internal connecting wires are not twisted. The central passage of the intelligent water distributor is sealed through an eccentric step shaft hole, the sealing performance is ensured by the O-shaped sealing ring (7), and the guide pipe (8) is convenient to assemble and increase for guiding when being used for assembling.
