Description
Technical field
The utility model relates to a kind of oil well underground survey device, is specifically related to shutoff of a kind of down-hole and pressure tester.
Background technology
At present oil well generally obtains the various information of reservoir by well testing, comes for post-evaluation with grasp the production scale of oil well and foundation dynamically is provided.Traditional well-logging method has three kinds of modes: one, that The Storage Pressure Guage is dark to the design degree down with tubing string, rise out just with tubing string when construction finishes and to obtain data, the data that this kind mode is obtained have blindness, when do not return to normal value because know the pressure of down-hole, time when surveying data can not correctly be grasped, lose time if the closed-in time has been grown, the data of having obtained if the time has lacked are not worth.Two, realize the direct-reading testing well of open and close well on ground, can obtain data at any time, but because the time of taking surface shut-in, pit shaft to preserve is long, acquisition is stablized the time of data and will be grown relatively.Three, adopt the mode well testing of throwing in the memory-type pressure meter, it is long that this mode pit shaft preserves the time, just can read data after also will salvaging out to pressure gauge, can not obtain in real time.Therefore all there is deficiency in above three kinds of methods, how could overcome that these are comprehensive not enough, and through Long-term analysis research, the development down-hole is thrown and blocked up the direct-reading well testing system and can avoid deficiency in traditional well testing mode.
The utility model content
At above problem, the utility model provides a kind of device that direct-reading pressure gauge and down-hole shutoff equipment are integrated, not only can realize downhole closing, can also directly the underground survey result directly be transferred to ground, the concrete mode of this programme is as follows: a kind of down-hole shutoff pressure tester, comprise and be located in joint, lock core is thrown stifled device, balancing pole and direct-reading pressure gauge, its improvement is, direct-reading pressure gauge and balancing pole link together, described balancing pole one end has pressure transmission hole, described pressure transmission hole is positioned at the lock core plugging device and is located in before the seal of joint, described pressure transmission hole is connected with the passage of balancing pole inside, the balancing pole inner passage other end is connected with the manometric pressure sensor of direct-reading, and described direct-reading pressure gauge is equipped with the described cable of cable socket with the balancing pole opposite end and is connected with ground receiving equipment by cable.
Another optimal way of this programme is: between described direct-reading pressure gauge and the cable socket weighted lever is installed, described weighted lever inside links together cable socket and direct-reading pressure gauge by lead.
Another optimal way of this programme is: described balancing pole and lock core are thrown between the stifled device inwall sealing ring.
Another optimal way of this programme is: described lock core is thrown stifled device and is located in locator card between the joint.
This programme will be thrown stifled device and the direct-reading pressure gauge links together, and finish the effect of down-hole shutoff and direct-reading, shorten the engineering time, utilize weighted lever to increase the balancing pole locating effect, reach the purpose of quick evaluation.
Description of drawings
Fig. 1 measures the plugging device schematic diagram
The specific embodiment
This programme process is as follows: as shown in Figure 1, between oil pipe and sleeve pipe, utilize packer sealing, install one earlier in the precalculated position of oil pipe and be located in joint 4, being located in joint 4 is straight-through cylinders, external surface and oil pipe sealing, have deck on the inner surface, can mesh and fix with the locator card 7 that lock core is thrown on the stifled device, it is hollow tubes of a U-shaped that lock core is thrown stifled device 6, opening one end is towards well head, on the outer wall there be and the locator card 7 and the sealing ring 8 that are located in coupling in the joint design, weighted lever 2, direct-reading pressure gauge 3, balancing pole 5 is connected in turn, weighted lever 2 other end stube cable sockets 1, link together by cable 11 and aboveground receiving system, the other end of balancing pole 5 inserts lock core and throws stifled device 6, and balancing pole 5 utilizes the seal 10 of outer ring to throw stifled device 6 with lock core and forms sealing, there is pressure transmission passage 12 balancing pole 5 centres, have pressure transmission hole 9 on balancing pole 5 tube walls and throw stifled device 6 pressure inside transmission channels with lock core to be communicated with.Pressure transmission hole 9 is positioned at lock core plugging device 6 and is located in before the seal 8 of joint 4, and the pressure sensor of direct-reading pressure gauge 3 is located at balancing pole 5 junctions and with pressure transmission passage 12 and connects.
To be located in joint 4 during work earlier and arrive projected depth down with tubing string, when the needs well testing, lock core thrown that stifled device 6 drops in the oil pipes and be located in joint 4 and automatically lock, the direct-reading pressure gauge that cable 11 is connected arrives projected depth 3 times again, the balancing pole 5 that connects on the direct-reading pressure gauge 3 inserts lock core and throws in the stifled device 6, balancing pole 5 utilizes the sealing ring 10 on the outer wall to throw stifled device 6 with lock core and forms the inner shutoff of oil pipe, finishes the shutoff operation of whole oil well down-hole.Strata pressure and fluid are in pressure transmission hole 9 enters balancing pole 5 pressure transmission passages 12, receive by direct-reading pressure gauge 3 probes that are positioned at balancing pole 5 other ends, after direct-reading pressure gauge 3 receives data, pass in the aboveground receiving equipment by cable 11, this programme has shortened pit shaft and has preserved the time, has reached the purpose that obtains reservoir information at any time.
