Abstract
The invention discloses a test string for stimulating the produced liquid section of a pumping unit, comprising a security core sleeve, a security upper joint, a security lower joint, a two-way anchor packer, a friction piece, a pull rod, a hollow-plunger pump, a piston rod, a hollow plunger and a horn mouth. The test string is characterized in that the security upper joint and the security lower joint are connected with an oil pipe through the security core sleeve, the security lower joint is connected with the two-way anchor packer, the friction piece is positioned on the centering device of the two-way anchor packer; the upper part of the pull rod is connected with the two-way anchor packer, the lower part thereof is connected with the piston rod through a box coupling, the bottom of the piston rod is connected with the horn mouth; the hollow-plunger pump is connected with the two-way anchor packer and drives the piston rod to vellicate up and down through the pull rod. Compared with the prior art, the invention has the advantages of simple structure, convenient use, low cost and ability of meeting construction requirements.
Description
One, technical field
The invention belongs to well recovery process test technical field of tools, is a kind of test string for stimulating produced liquid section of pumping unit concretely.
Two, background technology
Oil well needs to understand the output situation of oil, gas, water three-phase fluidised form in the various situation well-sinkings during recovering the oil, according to liquid producing profile log data adjustment development plan, and abundant mining-employed reserves, the shutoff water exit reaches the raising recovery ratio, the purpose that increases production and improves productivity.Mainly contain following several kinds of technologies at nonflowing well liquid producing profile log process aspect both at home and abroad: 1, rod-pumped well annular space log method: logger can only be lowered in oil sets annular space; Logger external diameter, admission parameter are restricted; Be wrapped on the oil pipe or the situation of instrumentation card in oil sets annular space owing to cable often occurring in the well logging process simultaneously, the well logging success rate is on the low side.Shengli Oil Field does not almost have the annular space producing profile testing over past ten years.2, submerged electric oil pump well logging method: connect one in oil pipe bottom and fall " Y " type joint, a termination submersible electric pump, other end order is to blanking plug, carries out well temperature, pressure buildup test after when needs are tested, pulling unidirectional blanking plug out.Electric pump and Y " type adapter assembly external diameter is big, can only be used for 95/8 " (245mm) sleeve pipe, the scope of application is restricted, and present domestic CNOOC has carried out this technology.3, dual string logging method: abroad for 95/8 " (245mm) the sleeve pipe suspension 51/2 " (139.7mm) or 7 " (177.8mm) oil well of sleeve structure; the dual string decentralized wellhead is set; test string descend oil well pump; under the normal production fluid situation of oil well, instrument by in the test string down to the measurement interval of interest, carry out producing profile testing.Liquid producing profile log adopts different logging modes according to dissimilar oil well production situation.
Oil well production string is divided into flowing well flow string and artificial lift completion tubular column (oil pumper, submersible electric pump, screw pump, jet pump completion tubular column).Can directly instrument be transported to the target zone position from oil pipe during the flowing well test logs well; Need the setting-up eccentricity well head during rod-pumped well test, logger is measured in oil sets annular space.At present the Shengli Oil Field flowing well seldom, most of artificial lift completion that adopts oil pumper and submersible electric pump to produce, its hole condition is with to produce the actual liquid producing profile log that can't use technological.
Along with increasing sharply of horizontal well quantity; Horizontal well is carried out liquid producing profile log under the situation that does not stop production; Can carry out dynamic monitoring to horizontal well; In time the relation of the oil in the admission pit shaft, gas, water three-phase fluid, divide stratum proportion, the individual layer output value, pressure, important parameter such as moisture, for realizing that rational exploitation provides foundation.For the horizontal well flowing well, producing profile testing can adopt crawl device, around technologies such as property pipes logger is passed oil pipe is transported to target zone and tests; The well that the Shengli Oil Field horizontal well possesses the blowing ability seldom, major part is the artificial lift completion that adopts submersible electric pump or oil pumper to produce, logger can't be lowered to net horizontal section and carry out liquid producing profile log.
Because the productive completion tubing string, the domestic liquid producing profile log of carrying out nonflowing well is few, utilizes between the oil well operational period test string down, and the producing profile testing that carries out straight well, high angle hole, horizontal well is to be badly in need of in the oilfield development process.
Three, summary of the invention
The object of the invention is exactly the defective that exists to prior art, provides a kind of ability to satisfy the test string for stimulating produced liquid section of pumping unit of construction needs.
Its technical scheme is: comprise safe core retainer plate, safe top connection, safe lower contact, bi-directional slip packer, friction piece, pull bar, hollow-plunger pump, piston rod, hollow plunger and horn mouth.Said safe top connection is connected with oil pipe through the safety core retainer plate with safe lower contact, and safe lower contact is connected with the bi-directional slip packer, and friction piece is positioned on the centralizer of bi-directional slip packer; Pull bar top is connected with the bi-directional slip packer, and the bottom is connected with piston rod through box cupling, and the piston rod bottom is connected with horn mouth; Hollow-plunger pump is connected with the bi-directional slip packer, and twitches up and down through pull bar drive piston rod.The present invention has simple in structure, easy to use, with low cost and can satisfy the advantage of construction needs compared with prior art.
