Abstract
A method for passing electric cable through oil tube in oil well features that an electric cable repeater is installed between oil tubes under oil-well pump but packer and the electric cable is connected with the instrument in well via the high-pressure sealing plug of said repeater, so the electric cable can by-pass through the packer to monitor the dynamic parameters of oil-bearing stratum under packer.
Description
The present invention relates to the method that oil well inner cable in the process of oil production passes through obstacle transmission of electric signals such as downhole oil tube wall and power supply, more properly is exactly a kind ofly to adopt the high pressure sealing technology to make cable pass through tubing wall in oil well to walk around the method that packer is realized signal of telecommunication transmission.
The dynamic parameter of 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 in rod-pumped well, has, like this because cable can't pass through packer, therefore conventional annular space log be can not carry out, thereby very big blindness and energy waste caused to production.
The objective of the invention is to propose the method that cable passes through oil pipe in a kind of oil well, existing to solve with dynamic parameter in annular space or the oil pipe measurement oil well, owing to descended packer between the payzone that in rod-pumped well, has, cable can't pass through packer, and the problem that can not carry out conventional annular space log that causes.
Technical scheme of the present invention is, be installed under the oil well pump being used for the oil pipe cable adapter that cable passes through oil pipe, between the oil pipe on the packer, high pressure sealing plug when cable is transferred to the oil pipe cable adapter along annular space on the oil pipe cable adapter passes oil pipe and links to each other with downhole instrument, thereby make cable walk around packer smoothly, realize monitoring at random the purpose of payzone dynamic parameter under the packer.
Technique effect of the present invention is, provide a kind of cable to pass through the method for oil pipe, adopt this method can realize that cable is connected with the logger of down-hole by packer smoothly, thus make ground at any time various dynamic datas under the production wells, the monitoring production status is in time adjusted production decision becomes possibility.This method is applied widely in addition, has practicality widely in having the oil well of packer.
Fig. 1 is a principle schematic of the present invention;
Fig. 2 is the structural representation of oil pipe cable adapter of the present invention.
Realize that embodiments of the invention are as figure.The oil pipe 2 that is used to recover the oil is housed among Fig. 1, and the oil well pump 4 in the oil pipe 2 is finished oil extraction operation under the pulling of sucker rod 3.
This method is that the instrument 8 of the dynamic parameter (as temperature, pressure) that will be used to measure oil well payzone 7 is installed on the oil pipe bottom, be installed under the oil well pump 4 being used for the oil pipe cable adapter 9 that cable passes through oil pipe 2, between the oil pipe on the packer 6, after logging cable 13 is transferred along annular space 15, high pressure sealing plug 10 on oil pipe cable adapter 9 passes oil pipe and links to each other with downhole instrument 8, make cable walk around packer 6 smoothly, thereby realize monitoring at random the dynamic parameter purpose of 6 times payzones 7 of packer.
The structure of oil pipe cable adapter as shown in Figure 2, it is outer through approaching with tubing size for oil pipe cable adapter 9, has the hole, garden of band screw thread on the wall, and high pressure sealing plug 10 is housed on it, high pressure sealing has sealing ring 11 beyond the Great Wall, to guarantee sealing; Metal-cored 12 and shell between by filling insulating material to protect its electrical apparatus insulation.
Claims (2)
1, the method that cable passes through oil pipe in a kind of oil well, it is characterized in that this method is to be installed under the oil well pump being used for the oil pipe cable adapter that cable passes through oil pipe, between the oil pipe on the packer, high pressure sealing plug when cable is transferred to the oil pipe cable adapter along annular space on the oil pipe cable adapter passes oil pipe and links to each other with downhole instrument, thereby make cable walk around packer smoothly, realize monitoring at random payzone dynamic parameter under the packer.
2, the method for passing through oil pipe according to cable in the described oil well of claim 1, it is outer through approaching with tubing size to it is characterized in that packer (9), have the hole, garden of band screw thread on the wall, high pressure sealing plug (10) is housed on it, high pressure sealing has sealing ring (11) beyond the Great Wall, between metal-cored (12) and the shell by filling insulating material.
