Abstract
The utility model discloses an underground wireless data exchange set, which mainly comprises an underground data measuring apparatus and an underground data read-back apparatus which are connected into a whole in a wireless coupling way through an antenna of the underground data measuring apparatus and the antenna of the underground data read-back apparatus. When applied, the underground data measuring apparatus and the underground data read-back apparatus exchange the measuring data in the wireless coupling way, and the data is sent back to the ground by a cable after completing the data exchange. The utility model can work in a narrow ring space of an oil jacket for a long time under the status without affecting the normal production of an oil well. The utility model can realize the data exchange and obtain the underground dynamic measuring data of the oil well under the high-temperature, high-pressure and high-salinity environment.
Description
Affiliated technical field
The present invention relates to a kind of device that is used for oil-water well down-hole dynamic test transfer of data, especially can be by the be coupled downhole data wireless exchange device of dynamic data under the testing well of antenna.
Background technology
At present, the oil reservoir technique of dynamic measurement has been with rapid changepl. never-ending changes and improvements.Yet oil-water well down-hole dynamic test data communication but is puzzlement oil reservoir logging technician's a a great problem always.
Current domestic and international oil-water well down-hole dynamic test data communication mainly contains: 1, cable transmission.Its shortcoming is a complex process, the cost height.2, downhole data storage, the ground playback.Its shortcoming is a poor in timeliness, has needed lower tubular column.3, downhole data by low-frequency sound wave along tubing transmission.Its shortcoming is that transmission range is short, and the data communication amount is little.
The patent No. of also have using is that 00100553.7 underground communication device with coil coupling withotu iron core adopts the mode of coil coupling to realize exchanges data, and by the oil pipe G.I.H, realize that the required space of exchanges data is bigger, and be not suitable for long-term work under the high salinity environment, therefore, The field is subjected to certain restriction.
Summary of the invention
In order to overcome the deficiency that the prior art The field exists, it is bigger to solve the required space of existing underground communication device with coil coupling withotu iron core exchanges data, be not suitable for the problem of long-term work under the high salinity environment, the utility model provides a kind of downhole wireless DEU data exchange unit.This device adopts antenna coupling system, can realize exchanges data in narrow oil sets annular space, and can long-term work under high temperature, high pressure, high salinity environment.
The utility model is achieved in that
The downhole data wireless exchange device is made of by underground data measuring instrument antenna and downhole data retaking of a year or grade instrument antenna coupling one underground data measuring instrument and downhole data retaking of a year or grade instrument.
The underground data measuring instrument is designed to an instrument pipe nipple, is connected with oil pipe by tubing coupling, is connected and is constituted by underground data measuring instrument antenna, pressure gauge, circuit, battery, protection tube, circuit tube, underground data measuring instrument starting taper.But long-term work is carried out dynamic monitoring in the down-hole to oil well.
Downhole data retaking of a year or grade instrument is designed to the downhole instrument of minor diameter, is linked in sequence and is constituted by cable head, collar locator, telemetry cartridge, temperature and pressure sensor, antenna circuit tube, downhole data retaking of a year or grade instrument antenna, downhole data retaking of a year or grade instrument starting taper.
During use, the underground data measuring instrument is connected with oil pipe by tubing coupling and is lowered in the oil well, connect power supply, underground data measuring instrument operation work, measure the oil well dynamic data, when measurement finishes, in the time of need reading data, downhole data retaking of a year or grade instrument just is lowered in oil pipe and the sleeve pipe annular space by cable, by the collar locator on the downhole data retaking of a year or grade instrument downhole data retaking of a year or grade instrument is positioned near the underground data measuring instrument, exchange survey data by underground data measuring instrument antenna and the coupling of downhole data retaking of a year or grade instrument antenna between two instruments, after exchanges data is finished, by cable data are sent to ground again, thereby finish the transmission work of oil-water well dynamic test data.At this moment, downhole data retaking of a year or grade instrument resets and waits for the next group exchanges data.
The beneficial effects of the utility model are, can be under the situations that does not influence the oil well ordinary production, and long-term work and under the high temperature, high pressure, high salinity environment, realizes exchanges data in narrow oil sets annular space, obtain oil-water well down-hole dynamic test data.
