Description
Technical field
The invention belongs to metrological testing technology field, relate to a kind of underground sucker rod multidimensional device for measuring radial pressure.
Background technology
Owing to having bar to recover the oil to have the advantages such as cost for oil production is cheap, management and maintenance convenient and applicability is strong, in oil recovery industry, be widely adopted, its shared ratio is up to more than 90% [horse is defended the country according to statistics, Yang Xin's ice etc. the deviating wearing between sucker rod and tube origin cause of formation and solution Review Study [J]. oil field equipment, 2009,38(1): 22～26]; It is also considered to present stage a kind of the most substantially, the most reliable and the most widely used oil production method, and significant period of time will occupy very important status from now on.
Because underground working is severe, the probability of sucker rod pumping device fails is higher.According to oil sector statistics, China present stage average every mouthful have bar producing well year operation 1.75 times [Fan Xiyan. solid sucker rod non-tubing oil extraction technical research [D]. Southwest Petrol University, 2007].Along with deepening continuously of oil-field development, the object of oilfield exploitation turns to thin layer and low permeability layer gradually, because formation condition is poor, natural production capacity is low, causes oil well pump constantly to be demoted, and the mean stress that sucker rod bears constantly increases; Be subject to the impact of well track simultaneously, force status on sucker rod is constantly changed, cause that sucker rod bar is disconnected, bar de-, [ten thousand benevolence are thin in the frequent generation of bar eccentric wear and pipe eccentric wear phenomenon, oil recovery technique handbook [M]. Beijing: petroleum industry publishing house, 1993| king sea is refined. sucker rod force analysis and optimum management [J]. and petroleum gas is learned, 2005,27(1): 121～123].These faults, particularly eccentric wear have increased oil well pipe leakage, the accident rate such as disconnected de-, and direct interference the normal production in oil field, has increased workover number of times and cost, has reduced the oil well operational use time, to oil field, has brought tremendous economic loss.There are some researches show, when there is eccentric wear phenomenon, the size of radial pressure that sucker rod bears is the key [Yang Jing that determines the degree of wear, willow people, Wang Chunsheng. eccentric abrasion of polymer-flooded well rods reason and prevention [J]. Daqing Petroleum Institute's journal, 2005,29(1): 114～128| Yang Ying, Wang Chunsheng. viscoelastic fluid acts on the radial force [J] on polymer displacement oil well sucker rod. Daqing Petroleum Institute's journal, 2005,29(1): 104～108].At present, oil field is for sucker rod mostly, sleeve pipe eccentric wear has been taked minimizing sucker rod, the measure of pipe eccentric wear, aspect the research preventing eccentric wear technology, developed fixing type centralizer for oil pumping rod (application number: 200920246462.6), pumping rod weighting tube (patent No.: ZL 200620077193.1) and Universal eccentric-wear-resistant collar of sucker rod (application number: 201020183938.9) etc., form some and prevented means and the instrument of eccentric wear, but because to forming the concrete mechanical environment of eccentric wear, particularly radial pressure is unintelligible, [horse is defended the country to cause taked the whole bag of tricks all to have to some extent its limitation, Yang Xin's ice etc. the deviating wearing between sucker rod and tube origin cause of formation and solution Review Study [J]. oil field equipment, 2009, 38(1): 22～26].Therefore production scene is in the urgent need to the device of the deep enough underground survey sucker rod of a kind of energy radial pressure.
About the measurement mechanism of down-hole shaft pressure, more existing patented technologies, but limitation of various degrees all.For example " downhole stored formula rod tube parametric detector " (patent No.: ZL 200420024926.6), designed and a kind ofly can detect sucker rod axial force and the isoparametric measurement mechanism of moment of torsion, but the parameter of this measurement device is not the principal element that affects sucker rod normal operation, limited to solving the major failure effects such as sucker rod partial wear, fracture." a kind of pipe column state detection device " (patent No.: ZL200820219679.3) proposed a kind of by down-hole and ground pick-up unit dimerous, realize the integrated measuring of well column temperature, axial force and tubing string slide displacement, but cannot detect the concrete numerical value of sucker rod radial pressure." a kind of device for measuring radial pressure of underground sucker rod " (application number: ZL201110236526.6) can realize and measure sucker rod radial force, the maximum radial pressure of its measurement is 500KN, smallest radial pressure is 10N, and maximum operating temperature is 120 ℃, this device is stressed by pipe nipple, distortion is passed to ring bush, the installation accuracy of ring bush plays an important role to the precision of measurement mechanism, but the pipe nipple of this device has determined that the installation of ring bush is very difficult, and lining is difficult to the long-term attitude that keeps requiring, and then be difficult to keep compared with high measurement accuracy for a long time, in addition this measurement device parameter can not illustrate the orientation that applies of suffered radial pressure, particularly when the stressed radial force of bar institute is inhomogeneous (bar circumferential deformation is inhomogeneous), measurement result is difficult to reflect true stressing conditions.Therefore existing instrument or technology still not can solve radially force measurement problem of underground sucker rod.
