Two, background technology
Replaced product category:
(1), traditional packing box class polished rod sealer
1, kind: the widely used traditional polish rod sealing in current each oil field mainly contains, the modified products of single packing box sealer, double-packing box sealer, single turriform packing box sealer, double tower shape packing box sealer, spherical packing box sealer and combined crosswise thereof etc., kind nearly more than ten is planted.
2, basic structure
Tradition oil-extractor polish-rod rubber packing_seal device, most typical is " 0 " shape rubber ring list packing box polished rod sealer, its structure is as shown in Figure 2.
The structure of this series products is mainly comprised of following components: 14, upper press cover swing handle; 15, leather is blue; 16, upper press cover; 17, " 0 " type rubber seal (or braiding packing sealing ring); 18, polished rod; 19, packing box; 20, packing box and production tree box cupling.
Other types product, as packing_seal devices such as double-packing box, tower box, spherical boxes, is to change substantially seal type as superimposed type, turriform or spherical into, and respective pinch device feature shape has been made part and improved, and all the other structures are basic identical.
3, know-why
As shown in Figure 1, by screwing upper press cover 16, promote leather blue 15, compress " 0 " shape rubber seal (or braiding packing sealing ring) 17, make it to hold tightly polished rod, thereby play sealing function, prevent in oil well with force feed, gas, water with the reciprocating motion of the polished rod well head of emerging.
Other each kind product technology principles are also basically identical, are all also by mechanical compaction mode, make blob of viscose hold polished rod tightly, play sealing function.
4, product function, effect
The function of tradition polish rod sealing is, by compressing wear resistant packing, polished rod implemented to " locking " sealing, prevent in oil well with force feed, gas, water with the reciprocating motion of the polished rod well head of emerging.
This series products has been continued to use century more than one, facts have proved that it can play certain sealing function at the use initial stage, but existing problems are a lot, can not adapt to oil field modernization construction needs, is badly in need of update.
5, existing problems:
As shown in Figure 2, adopt mechanical compaction blob of viscose to implement " locking " sealing to the polished rod in moving back and forth, existing problems are mainly manifested in following eight aspect:
(1), cause serious environment pollution.
" locking " sealing must cause rubber packing (or braiding packing sealing ring) wearing and tearing, what first from wearing and tearing slot leakage, go out is oil field gas, according to United Nations Environment Programme (UNEP) official website, announce the about 13600000000m of natural gas, oil field gas that discharge to atmosphere every year at produce oil, gas well in the whole world
3.Natural gas, oil field gas main component are CH
4(also there is a certain amount of SH
2), its absorption and releasing heat ability are far above CO
2, belong to Super High Carbon discharge, be depletion of the ozone layer, greenhouse effect expansion and the important root that causes acid rain.In oil field, cannot see like this, impalpable poisonous, pernicious gas all discharging every day in a large number.After packing may wear to a certain degree, crude oil and the highly mineralized formation brines ground of will leaking, causes the severe contamination of ground surface environment; If oil well is in farmland, will cause crops dead in flakes.
(2), labor strength is large.
For packing box is not leaked, oil recovery workman must make an inspection tour well site every day, tightens packing gland; The application life of packing is generally not long, within every 1～2 week, must stop production and change new packing; 1 class of oil recovery carries out this two daily operations to tens up to a hundred mouthfuls of oil wells, is workpeople's maximum burden.Especially in the winter time northern oil field conducts a field operation under the adverse circumstances of subzero one, 20 degree, and its arduous degree is well imagined.
(3), potential safety hazard.
The gas overflowing from packing box is natural gas, and its main component is CH4, C2H6, C3H8 etc.; According to different geological conditions, also contain more or less H2S, the former is inflammable and explosive, and the latter's respiratory system of burning, causes people's death by suffocation.Therefore say, it is the serious potential safety hazard in oil field that packing leaks.
(4), increase energy consumption.
In pumping production process, no matter be upstroke or down stroke, polished rod braking state in being held tightly by packing all the time, has increased the resistance of motion, thereby has also just increased oil pumper energy consumption.
(5), waste resource.
Blob of viscose packing (or braiding packing sealing ring) is by after abrasion, and between polished rod, produces gap, and along with extend service time, this gap constantly expands, and the band force feed in oil well, gas, water are constantly emerged, overflow loose from gap, have wasted valuable resource.
(6), damage polished rod.
Because polished rod is all the time in mechanical pressure and hold Frotteurism tightly, frictional dissipation makes polished rod from the coarse to fine, and fatigue stress cracks polished rod inside, and double action has shortened polished rod application life greatly.
(7), easily cause sucker rod partially to rub.
Because polished rod is all the time in rigidity oppression state, when its motion departs from oil well axis, will drive sucker rod below (short seven, 800 meters, long two, three kms) also depart from oil well axis and move, cause sucker rod partially to rub, thereby increase oil pumper power consumption, and easily rub rod collar, cause disconnected bar accident, oil well is forced to stop production.
(8), production suspension induced losses is large.
As mentioned above, use packing box polished rod sealer, the frequent replacing packing bringing, change polished rod, cause that sucker rod rubs partially, disconnected bar, the operations such as well workover, all must stop oil pumper work.Individual well is like this, and each oil field is all like this.According to incompletely statistics, the energy consumption that causes every year due to packing problem in the whole nation, material consumption, production suspension induced losses, operating cost etc. do not descend hundred million yuan of hundreds ofs.
(2), magnetic fluid polished rod sealer for oil production in oilfield
I Deng Haibo obtains magnetic fluid polished rod sealer for oil production in oilfield utility model patent on March 4th, 2009, and the patent No. is ZL200820065400.0, and its overall structure is as Fig. 3.
