Embodiment Construction

[0025] Such as figure 1 As shown, the on-line detection method of a kind of oil pipe scene provided by the present invention comprises the following steps:

[0026] (1) Equipment installation: Install the tubing detector on the wellhead flange plane with wellhead flange screws, then use a dedicated 12-core cable to connect the tubing detector to the control panel, and then connect the control panel to the computer through a USB communication line ;

[0027] (2) Parameter setting: turn on the computer, open the on-site tubing inspection application software, enter the well number and inspection date to be inspected in the dialog box that pops up, and confirm. Click "Settings" on the detection interface, select the appropriate "Detection Specifications", and then set the critical value of the first type of alarm (pipe wall hole) and the second type of alarm (wall thickness);

[0028] (3) Instrument calibration: Run a brand-new tubing pup joint of about 2 meters in the well wit...

Abstract

The invention provides an online detection method for an oil pipe field. The method comprises the following steps: (1) equipment installation; (2) parameter setting; (3) instrument calibration; (4) simulation test; (5) oil pipe detection; (6) field evaluation; (7) field identification; (8) equipment detachment; and (9) detection report. An oil pipe in a well is detected on line by using a well mouth oil pipe detection instrument during drilling. The method is low in operation cost, detection results are obtained in real time, time apart of drilling is not occupied, drilling in an operation process is not different from conventional drilling, and additional operation risk is not added. The operation cost of oil pipe detection is reduced, and the construction safety and aging are enhanced.

Description

technical field [0001] The invention relates to the field of exploration and development of oil and gas fields, in particular to an oil pipe detection method. Background technique [0002] In the process of oil and gas exploration and development, oil pipes are widely used in oil fracturing and oil recovery operations. During the operation, the tubing has long been subjected to mechanical shock, erosion by high-pressure sand-carrying fluid, repeated wear of the suction pump, back-and-forth eccentric wear of the sucker rod, various strong acids, strong alkalis, and high-salinity formation fluids. Corrosion and other damage caused by oil pipe deformation, eccentric wear, cracks, holes, pipe wall thinning, etc., in severe cases, will cause industrial accidents such as pipe string leakage and pipe string breakage during construction. [0003] In order to avoid the above-mentioned industrial accidents, it is necessary to conduct regular physical examinations on the oil pipes in ...
