Abstract

A non-cable near-distance method for measuring the dynamic parameters of oil well features that a memory-type multi-parameter measurer with audio signal transceiver is arranged under the packer and is turned on by an audio signal transceiver over the packer in remote control mode. The measured data is transmitted upward and then recorded by the recorder.

Description

Non-cable near-distance dynamic parameters logging method for oil well

The present invention relates to oil well and the dynamic parameter collection of well down-hole in the Petroleum Production, a kind of more precisely method that in oil well, adopts no cable transmission technology that the following payzone dynamic parameter of packer is measured.

Dynamic parameter in the oil well all is to adopt annular space or cross the oil pipe measurement at present, but because the needs of oil production technology, descended packer between the payzone that has in the oil well, so just can't monitor the current intelligence of the payzone below the packer in the oil well, caused very big blindness and energy waste to production.

The purpose of this invention is to provide a kind of measuring method of monitoring the current intelligence of the following payzone of packer.

Technical scheme of the present invention:

1, the following mounting strap of packer has the memory-type measuring multiple parameters instrument of acoustic signals transceiver in payzone, and memory-type measuring multiple parameters instrument stores the various parameters in down-hole that collect in the memory into;

2, the collector that will have the acoustic signals transceiver is transferred to above the packer with cable, by the acoustic signals transceiver in the acoustic signals transceiver remote control start-up parameter measuring apparatus in the collector, the data of memory-type measuring multiple parameters instrument storage are delivered in the collector, noted by the control register instrument again.

This measuring method had both realized that wireless telemetering was gathered the following payzone dynamic parameter purpose of Wel packing at random, solved owing to can't monitor the current intelligence of the payzone below the packer in the oil well, thereby cause the problem of blindness and energy waste to production, simultaneously make the power consumption that transmits and receives device be reduced to as far as possible little degree again, thereby the time of downhole stored formula measuring multiple parameters instrument work is prolonged as much as possible.

Description of drawings:

Fig. 1 is the schematic diagram of this measuring method.

Embodiment:

As shown in the figure, the following mounting strap of packer has the memory-type measuring multiple parameters instrument 5 of acoustic signals transceiver in payzone, and memory-type measuring apparatus 5 is by monolithic processor controlled intelligent memory-type multi-parameter logger; 5 various parameters in down-hole that collect of memory-type measuring multiple parameters instrument such as pressure, temperature, flow etc. store in the memory; The Ground Control register instrument 1 that can enroll data at random with have the recline collector 2 of device 3 and acoustic signals emission recipient 4 of electromagnetism and be connected by cable; The recline work of device 3 of the transmission of a Single-chip Controlling order and data and electromagnetism is arranged in the collector 2.When needs admissions and down during data by transferring to collector 2 on the packer 8 along annular space with cable in ground, electromagnet 9 is installed on the oil pipe 7, Ground Control register instrument 1 sends order then, at first start the electromagnetism device 3 that reclines, magneto-dependent sensor in it is sought the orientation of oil pipe, it is attached on the oil pipe 7 automatically, restart the downhole stored formula measuring apparatus 5 emission acquisition of transceiver 4 below packer 8 in the collector 2, after single-chip microcomputer in the downhole stored formula measuring apparatus 5 is received acquisition by receiver 6, the data that write down in the memory are delivered in the collector 2 by transceiver 6, by cable it is delivered to the Ground Control register instrument again and note, realized that the signal of packer about in the of 8 do not have the cable transmission.
