Abstract
The utility model relates to a pressure measuring device for hydraulic piston pump oil extracting wells in oil fields (particularly high congealing oil fields), which is composed of a fishing head 1, a lifting valve core 2, a lifting leather cup 5, a leather cup supported joint 6, a pressure gauge 9, a pressure gauge protecting cylinder 10, an upper joint 7, a lower joint 12, a pressure guiding joint 13, an inhaling and discharging valve ball 16, a valve ball cover 19, a cylinder cover joint 21, etc. The pressure measuring device can be arranged on the pump body of a hydraulic piston pump to accurately measure the data of the flow pressure, the static pressure and recovery pressure of various oil wells (particularly high congealing oil fields). The pressure measuring device provides basis for the production of the oil wells and the reasonable exploitation of oil reservoir and solves the problems of problems that big error is generated when the hydraulic piston pump wells measure the pressure and the high congealing oil fields can not measure the static pressure or the recovery pressure.
Description
The utility model relates to a kind of device that is used for oil field (particularly hypercoagulation oilfield) hydraulic piston pump producing well pressure measurement.
Hydraulic piston pump is one of underground equipment of mechanical oil recovery (exploitation of particularly high oil with fixed attention).At present, the used pressure measuring controller of hydraulic piston pump sump is lowered to pressure tester with steel wire for logging in well, because of the poorly sealed force value error that records that causes is bigger, and can only flow measurement presses at high-solidifiability oil well, can not survey oil reservoir and recover pressure.Thereby, can't satisfy to get and get accurate data entirely, the needs of foundation are provided for oil well production and oil reservoir reasonable development.
Task of the present utility model is to provide a kind of pressure tester that is used for hydraulic piston pump oil recovery (the particularly high oil that coagulates) well, and this kind pressure tester can adapt to stream, the static pressure test of all kinds of oil reservoirs.Gai Ya device can be contained on the hydraulic piston pump pump housing, and drop into the same with free throw-in type pump played the production pumping action in the underground work tube, and the stream that pressure gauge wherein can write down simultaneously under this production status is pressed; If change the pressure guiding joint in this pressure tester, then can carry out the recovery pressure or the static pressure test of high-solidifiability oil well.
The utility model is to realize like this.It is by fishing head 1; poppe tvalve core 2; joint 3; clamp nut 4; promote leather cup 5; leather cup supported joint 6; top connection 7; last damping spring 8; pressure gauge 9; pressure gauge protection tube 10; following damping spring 11; lower contact 12; pressure guiding joint 13; joint ring 14; inhalation valve spring 15; suck valve ball and ball cover 16; suction valve seat 17; valve sleeve 18; discharge valve ball and ball cover 19; blow off valve spring 20; cylinder sleeve joint 21 is formed (when being used to survey high-solidifiability oil well recovery pressure; then with lower contact 12; pressure guiding joint 13 is replaced by special lower contact 12 and special pressure guiding joint 13, adds in special pressure guiding joint in addition and breaks screw 22).Its number of assembling steps is as follows: the poppe tvalve core 2 of packing in fishing head 1 links to each other the negative thread of joint 3 upper ends with the pin thread of fishing head 1 lower end; To promote leather cup 5 is enclosed within on the leather cup supported joint 6, again with on the clamp nut 4 on the leather cup supported joint 6 of top band pin thread, upper end pin thread one end of leather cup supported joint 6 is reinstalled joint 3 lower ends of being with negative thread, will be with the top connection 7 blind hole ends of pin thread to link to each other with the negative thread of leather cup supported joint 6; Lower contact 12 lower end pin threads are linked to each other with pressure guiding joint 13 upper end negative threads, then with an end of pressure guiding joint 13 attached cavities pack into inhalation valve spring 15, suck valve ball and ball cover 16, suction valve seat 17; Arbitrary end of the valve sleeve 18 of two ends band negative thread is linked to each other with the lower end pin thread of pressure guiding joint 13, in cylinder sleeve joint 21, pack into then and discharge valve ball and ball cover 19, blow off valve spring 20, with cylinder sleeve joint 21 install each part of blow off valve one the Dragon Boat Festival screw thread link to each other with negative thread on the valve sleeve 18; To play damping spring 11 to pack in the cavity of lower contact (or special lower contact) 12; pressure gauge protection tube 10 arbitrary ends of two ends band negative thread are linked to each other with lower contact (or special lower contact) 12 pin threads; with pressure gauge 9 pack on the pressure gauge protection tube 10(pressure gauge arrow up) and make its seat on spring base, the top connection 7 that damping spring 8 is housed is linked to each other by a screw thread and pressure gauge protection 10 upper end.After each connector that above-mentioned assembling is finished with spanner tightened, this device just can use.
When flow measurement is pressed, this pressure tester is contained on the hydraulic piston pump pump housing on the pump top of dismantling (need select the pump housing of corresponding discharge capacity by piezometric well for use), as throwing common production pump, from well head it being dropped into pump barrel (notes setting upright when well head is transferred, and with well head gate complete opening), carry with an amount of power fluid then and send into seating nipple.When the hydraulic piston pump operate as normal of this pressure tester was housed, the pressure of Pump Suction Nozzle changes just to be noted by pressure gauge, promptly finishes stream and presses test assignment.After this; conventional pump is the same to be changed the well head flow process into hydraulic piston pump that anti-circulation process can trip out the band pressure tester (attention is gently held up slowly and put with rising in that the pressure gauge clock is specified when walking in the scope; in order to avoid the build-up of pressure meter damages); after putting down pump from well head, dismantle the pressure charts that pressure gauge protection tube 10 takes out in the pressure gauges 9 and can calculate institute's flow measurement pressure value.
Survey when recovering pressure or static pressure, if thin oil (ordinary crude oils) well, the assembling of this device, input and the course of work and above-mentioned flow measurement are pressed roughly the same, and institute's difference is in need oil well was closed a well in to needed recovery time, and pressure gauge just can be noted the oil well pressure recovery situation.If high-solidifiability oil well, must change the outfit have special top connection 12 and special pressure guiding joint 13(wherein be equipped with under the qualification pressure of design, connect the disconnected screw 22 of breaking) pressure tester.Survey when recovering pressure, STP is brought up to the pressure of breaking of breaking screw 22, break screw, after 22 quilts are broken tubing and casing is communicated with, form power fluid circulation insulation passage at the top of pump.At this moment, stop the work of pump, strata pressure begins to recover and is noted by pressure gauge, trips out specific pump with above-mentioned pressure tester as conventional pump in the scope when pressure gauge is stipulated away, and takes out and can obtain to recover pressure or static pressure data after pressure chart calculates.
The utility model compliance is strong, can be used for hydraulic piston pump oil recovery (the particularly high oil that coagulates) well and measure stream pressure, static pressure and recovery PRESSURE DATA exactly.Overcome the deficiency of prior art, this kind pressure tester is simple in structure, and is easy to use, is suitable for and applies.
