Description
Technical Field
The invention relates to the field of underground perforation tunnel depth detection for oil and gas wells, in particular to a hydraulic azimuth support.
Background
Perforation penetration depth is an important index for evaluating parameters of the perforator, and the perforation penetration depth directly influences the development effect of an oil and gas well, so that the grasping of the actual penetration depth of the perforating bullet in the pit has important significance. At present, the perforation penetration detection technology can only perform simulation detection on the ground, and cannot measure the actual penetration depth of the perforating charges in the underground stratum. The ground simulation detection mainly comprises concrete target detection, bailey sandstone target detection and steel target detection, and as the lithology of the ground simulation detection is different from that of a perforation layer in the pit, and the underground has a certain temperature and pressure, the ground cannot truly simulate the actual perforation condition in the pit, so that the penetration method of the ground detection perforator cannot represent the actual penetration depth of the perforator in the pit. Thus, there is a need for a downhole perforation tunnel depth detection device to detect perforation penetration. The azimuth support is an important component in the underground perforation tunnel depth detection device, the existing support has small anchoring force, is easy to play in the moment of perforation, and is easy to cause that a probe cannot be aligned with a perforation hole after a perforation depth detector sits on a key, so that the perforation depth cannot be accurately measured.

The anchoring and unhooking processes are as follows: the quick connector, the magnetic positioning instrument, the anchoring release tool and the hydraulic azimuth support which are matched with the hydraulic azimuth support are conveyed to a target layer together in a cable conveying mode. The lower end of the anchoring release tool is connected with the sealing rod 1 through threads. After reaching the target layer, the electronic switch of the anchoring release tool is opened by controlling the ground instrument, and the liquid in the well flows into the hydraulic chamber 23 along the internal channel of the anchoring release tool, the central channel 10 in the sealing rod 1 and the liquid inlet 24 of the piston 21, so that upward thrust is generated on the lower end surface of the piston 21. By calculation, a 1000 meter vertical deep water column can generate 5.2 tons of upward thrust. Since the downward force of the air chamber 20 on the piston 21 is much smaller than the upward thrust of the liquid on the piston 21, the piston 21 moves upward. The piston 21, the center rod 28, the guide joint 51, the lower fluke 49, the stop ball C47, the lower leaf spring 44, the lower retaining ring 43, and the lower fluke 42 move upward together because they are connected together. Since the component of the friction between the lower fluke 42 and the lower cone 38 in the vertical direction is greater than the weight of the lower cone 38, the upper fluke seat 34, the limit steel ball a36, the upper leaf spring 31, the upper fixing ring 30, the upper fluke 29, the above-mentioned parts move upwards. The upper fluke 29 moves upwards along the conical surface of the upper cone 27 until the upper cone 27 anchors the upper fluke 29 against the casing wall. At this point, the lower cone 38, upper fluke 34, stop ball 36, upper leaf spring 31, upper retaining ring 30, upper fluke 29 cease to move upward. Because the lower fluke 42 has not anchored the C47, the lower leaf spring 44, the lower fixation ring 43, the lower fluke 42 continue to move upwards until the lower fluke 42 is also anchored to the casing inner wall. The thrust rod 16, the locking ball 13 and the sealing rod 1 are driven to move upwards in the upward movement process of the piston 21, and when the locking ball 13 moves to the position of the inner diameter expansion of the lower cylinder 12, the locking ball 13 unlocks the sealing rod 1, and the anchoring release tool is released from the hydraulic azimuth support. And then the cable, the quick connector, the magnetic positioning instrument and the anchoring release tool are lifted out.
After the hole depth is measured, the anchoring process of the hydraulic azimuth support is released as follows: and a quick connector, a magnetic positioning instrument and a hydraulic anchor removing tool which are matched with the hydraulic azimuth support are conveyed to a target interval in a cable conveying mode. The hydraulic anchor-releasing tool can move relatively under the action of hydraulic pressure between the central rod and the outer cylinder, and the outer cylinder moves upwards relative to the central rod. The lower end of the central rod of the hydraulic anchor removing tool is connected with an anchor removing rod, and the lower end of the outer cylinder of the hydraulic anchor removing tool is provided with 3 uniformly distributed catching keys. In the process of cable lowering, after the lower end of the hydraulic anchor removing tool contacts with the hydraulic azimuth support, under the action of the gravity of the cable and the tool and the guiding action of the guiding groove in the catching groove 3,3 catching keys connected with the outer barrel at the lower end of the hydraulic anchor removing tool are moved into the lower catching groove of the catching groove 3, namely the point A 1、A2、A3 shown in figure 2. Then, the cable is lifted up, 3 fishing keys 3 are moved up along the track to point B 1、B2、B3, at which point the hydraulic de-anchor tool captures the hydraulic azimuth support. The cable is kept in a straight state, an electronic switch at the upper end of the hydraulic anchor releasing tool is turned on by controlling the ground instrument, the pressure of a hydrostatic column in the well enters 5 hydraulic cylinders which are connected in series of the hydraulic anchor releasing tool, each hydraulic cylinder can generate 6.09 tons of anchor releasing force under the condition of 1000 meters of water column in vertical depth, and the total of 5 hydraulic cylinders generates 30.45 tons of anchor releasing force. Under the action of the anchor removing force, the center rod of the hydraulic anchor removing tool moves downwards. Because the hydraulic anchor removing tool anchor removing force is larger than the hydraulic azimuth support anchor force, the hydraulic anchor removing tool anchor removing rod props against the upper end face of the thrust rod 16 of the hydraulic azimuth support, and the thrust rod 16 is pushed to move downwards. Because the thrust rod 16 is threadably coupled to the hydrodynamic bearing support center rod 28, the center rod 28 moves downward. The center rod 28 moves the guide joint 51, lower fluke socket 49, lower stop steel ball 47, lower leaf spring 44, lower retaining ring 43, lower fluke 42, lower cone 38, upper fluke socket 34, upper stop steel ball 36, upper leaf spring 31, upper retaining ring 30, upper fluke 29 downward. Finally, lower fluke 42 and upper fluke 29 are moved to the lower ends of lower cone 38 and upper cone 27, respectively. Since the lower cone 38 and the upper cone 27 are tapered from the upper to the lower outer diameters, the upper fluke 29 and the lower fluke 42 are retracted by the upper leaf spring 31 and the lower leaf spring 44, releasing the anchoring state of the hydrodynamic bearing support. At this time, 3 catching keys at the lower end of the outer barrel of the hydraulic anchor removing tool are respectively positioned at the position of the upper catching groove B 1、B2、B3 of the catching groove 3, and the cable is lifted up, so that the hydraulic azimuth support can be lifted out and recovered.
