The electric pump well underground double-test pressure guiding device has the function of collecting oil pipe pressure and ground pressure data synchronously and can effectively improve the accuracy of the test data.
Description
Technical field: the utility model relates to a kind of electric pump well testing pressure down hole device, is specifically related to the two pressure guiding devices of surveying in a kind of electric pump well down-hole.
Background technology: electric pump well is one of oil field equipment, in oil producing operation is produced, tubing pressure and strata pressure data are dynamically very important to the production of analyzing and grasp down-hole situation and oil well, and accurate normal, the efficient operation that could guarantee electric pump well must be got entirely, be got to data.Usually the electric pump well testing pressure down hole device of usefulness is made up of down-hole, ground two parts now, there are seating nipple, pressure valve in the down-hole, there are connector and the empty tube of test in ground, can enroll pressure in the submerged electric oil pump well oil casing annular space with the supporting use of pressure gauge under the situation of fixed tubular column.But owing to former thereby cisco unity malfunctions such as pressure valve, connector stop up sometimes, sealing ring blow-by, oil pipe internal pressure and pressure gauge are ganged up mutually, the actual change situation that does not reflect the stratum internal pressure, the test one-time success rate is lower, increased the number of times of test repeatedly, particularly when measuring the pressure recovery, produce stream and press the inaccurate of admission, will directly influence the explanation accuracy of test data.
The utility model content:
Lower in order to solve the test success rate, the problem of the accuracy of raising test data, the utility model provides a kind of electric pump well down-hole two pressure guiding devices of surveying.This device has the function of disposable synchronous collection tubing pressure and formation pressure data, can improve the accuracy of test data.
The technical solution of the utility model is: the two pressure guiding devices of surveying in a kind of electric pump well down-hole, comprise that fishing head, main body and the end are stifled, main body is built-in with binary channels blocking type pressure gauge, the manometric lower end of binary channels blocking type that has axial hole, radial hole and a packing_seal circle has inner seal ring and is threaded with sealing cap, between the stifled endoporus in the sealing cap and the end damping spring is arranged.
Beneficial effect: because this device contour structures and pressure valve are basic identical, interior dress binary channels blocking type pressure gauge, the bidirection press sensor is installed in the pressure gauge, manometric lower end by the seal with screwed joint cap after, inner surface with main body utilizes four road packing_seal circles and main body inner wall on the pressure gauge to seal again, packing_seal circle and pressure measurement seating nipple sealing outside four roads on the main body outer wall realizes tubing pressure and strata pressure effectively separating in pressure guiding device.Because this device has the function of disposable synchronous collection tubing pressure and formation pressure data, therefore stopped that pressure valve, connector stop up sometimes, sealing ring blow-by etc. is former thereby the phenomenon of cisco unity malfunction, and reach the purpose that improves the pressure measurement one-time success rate, thereby improve the accuracy of test data.

The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: the two pressure guiding devices of surveying in this electric pump well down-hole comprise fishing head 14, and the main body 8 that has sealing ring 13 with top is threaded, and the end stifled 1 that has sealing ring 2 is threaded with the lower end of main body 8; Main body 8 is built-in with binary channels blocking type pressure gauge 12, dual pressure sensor (17 is installed in the inside of this pressure gauge 12,18), have axial pressure transmission through hole 16 on the top of this pressure gauge 12, the centre position has packing_seal circle 10, the bottom has packing_seal circle 6, has a pressure transmission through hole 7 radially near sealing circle 6 places, and the lower end has inner seal ring 5 and is threaded with sealing cap 4; Between the endoporus at the sealing cap 4 and the end stifled 1 damping spring 3 is arranged; Have packing_seal circle 11 outside four roads on the external surface of main body 8, there is strata pressure pressure transmission passage 9 at the position therebetween; Tubing pressure pressure transmission access opening 15 is arranged on the fishing head 14.
In the test process, because this device contour structures is basic identical with the pressure valve of present usefulness, earlier pressure valve in the well is pulled out, the end stifled 1, directly be sitting on the valve seat, four road packing_seal coils 11 of main body 8 external surfaces are with the main channel sealing of pressure measurement seating nipple, packing_seal circle (10 on the binary channels blocking type pressure gauge 12,6) realize sealing with the inner surface of main body 8, strata pressure is directly delivered to the upper sensor 18 of pressure gauge 12 by pressure transmission access opening 9 on the main body 8 and the radially pressure transmission through hole 7 on the pressure gauge 12, and tubing pressure is delivered to the lower sensor 17 of pressure gauge 12 by the axial pressure transmission through hole 16 on pressure transmission through hole 15 on the fishing head 14 and the pressure gauge 12.Behind the EOT, this device is salvaged ground, unload binary channels blocking type pressure gauge 12 and carry out the data typing by fishing head 14.The characteristics that the dual pressure sensor (17,18) that this device utilizes binary channels blocking type pressure gauge 12 and inside to install is gathered have synchronously realized the disposable purpose that reaches strata pressure in the oil pipe of enrolling simultaneously, have effectively improved the accuracy of test data.This device also is better than the effect of seat valve pressure measurement to the distortion of testing pressure down hole valve seating nipple, substandard testing well test effect.
