Abstract
The invention relates to the technical field of oil extraction engineering and belongs to a pressure monitoring method for use in vertical well wall small-diameter open hole horizontal well drilling of oil-water wells. The invention solves the real-time pressure monitoring of a vertical well wall small-diameter open hole horizontal well drilling method on ground. The method mainly uses a ground test system 1, a cable 2 and a test connector 3, allows a drive pressure P in a piston cylinder 5 to be received at the position of the test connector 3 after pressure driving, and is mainly used in a method for vertical well wall small-diameter open hole horizontal well drilling of oil-water wells. The method has the advantages that: the structure is simple; the control is convenient; and the whole hydraulic drilling process is monitored in real time by monitoring the pressure change of the method for vertical well wall small-diameter open hole horizontal well drilling of oil-water wells.
Description
Technical field:
The present invention relates to the oil field technical field of oil production engineering, belong to a kind of pressure monitoring method of vertical well wall small-diameter open hole horizontal well drilling of oil-water wells.
Background technology:
At present sidetrack horizontal well is to utilize whipstock and window to mill awl, and is at design attitude that sleeve pipe is worn out and form window, gets out horizontal hole with the sidetracking drilling tool then.The operation situation was carried out real-time monitoring pressure when the SIDETRACKING TECHNOLOGY of horizontal well can't realize boring, and the present invention carries out real-time monitoring pressure by the down-hole pressure feedback to the open-hole horizontal well perforating job, has solved the problem that can't monitor open hole horizontal well drilling.
Summary of the invention:
The objective of the invention is in order to solve that existing horizontal well drilling technology can't be realized the open hole horizontal well drilling monitoring problem and the pressure monitoring method of a kind of vertical well wall small-diameter open hole horizontal well drilling of oil-water wells of designing.
Technical scheme of the present invention is by realizing with lower device: it is by ground test device, cable, and test splice is formed; Wherein testing arrangement is connected with cable, and the cable lower end is connected with test splice; Above-mentioned technology realizes by following steps:
A. at first with assigned address under the perforation tool lower going-into-well, grappling;
B. by ground test device test splice is lowered into the down-hole assigned address by cable then, docks with the downhole perforation instrument;
C. the operating pressure P at perforation tool nozzle place
jWith the pass of transmission pressure P in the piston rod be P=kP
j, during construction oil pipe is suppressed, can receive transmission pressure P in the piston rod by test splice place after the pressure transmission, and propagate by cable, finally, can realize operating pressure P thus to the perforation tool nozzle in the ground test device feedback
jReal-time monitoring, and can judge the waterpower drilling depth according to pressure-time curve.
Compared with the prior art the present invention has the following advantages: owing to take said method, can monitor in real time horizontal well drilling in the down-hole, improve the success rate of horizontal well drilling.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present invention;
Fig. 2 is an A part partial enlarged drawing of the present invention.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing: it is by realizing with lower device: it is by ground test device 1, cable 2, and test splice 3 is formed; Wherein testing arrangement 1 is connected with cable 2, and cable 2 lower ends are connected with test splice 3; Above-mentioned technology realizes by following steps:
A. at first with assigned address under perforation tool 4 lower going-into-wells, grappling;
B. by ground test device 1 test splice 3 is lowered into the down-hole assigned address by cable 2 then, docks with downhole perforation instrument 4;
C. the operating pressure P at perforation tool 4 nozzle places
jWith the pass of transmission pressure P in the piston rod 5 be P=kP
j, during construction oil pipe is suppressed, can receive transmission pressure P in the piston rod 5 by test splice 3 places after the pressure transmission, and propagate by cable 2, finally, can realize operating pressure P thus to perforation tool 4 nozzles in ground test device 1 feedback
jReal-time monitoring, and can judge the waterpower drilling depth according to pressure-time curve.
