Description
Technical field
The present invention relates to the verification tool of petroleum industry oil-water well oil pipe column sealing property, particularly a kind of oil-water well is more
Function tests pipe construction device and its construction method, available for checking oil pipe column before the constructions such as oil-water well squeezing ash, set milling, sand washing
Sealing property, test Guan Houke and carry out lower step construction as needed.
Background technology
Oil-water well sealing of checking oil pipe before squeezing ash, set milling or special construction is the weight for ensureing underground work safety
Process is wanted, current pipe method of testing there are two kinds：A kind of be connected to ball seat under the bottom of tubing string to after design attitude, to oil pipe
Interior pitching, treats that steel ball falls into ball seat, the sealing for the checking oil pipe that just building the pressure, then anti-flushing well washes out steel ball, then carries out lower step
Construction；Another is lower cement injecting sliding sleeve, pitching test oil pipe it is qualified after, continue to pressurize to destroy sliding sleeve to fall into cage, squeezed
Cement injecting or other constructions.The first in both approaches：When running into that tubing string is large diameter oil tube in formation leakage or well, instead
Wash ball difficult or can not wash out at all, cause construction failure, need to emit and spray oil pipe and do over again, not only pollution environment but also extend
Operation construction period, add operating cost.Second method：Although solving the problems, such as to test pipe, also needed to after pipe is tested higher
Pressure hits sliding sleeve down, easily causes oil pipe burst, and ground can not but judge that the pressure that oil pipe burst is caused declines or tested
The pressure decline that unqualified, tubing string is caused is managed, erroneous judgement is easily caused and triggers down-hole accident.Both instrument generally existings are total to
Sex chromosome mosaicism is：When demand sand washing in well or back-up sand construction cause that sand face is too high, must carry out construction, all exist and be located at
The fluid hole of middle and upper part and the distance of tool bottom are excessive, from the sand washing liquid impulse force of fluid hole excessively stream it is too small, punching can not be met
Sand requirement.
At present, be ensure underground work safety, underground set milling operation and squeezing off operation test pipe it is qualified after, be usually
Independent lower tubular column completes underground set milling operation and squeezing off operation again, causes activity duration length, operating cost high.
Therefore, pipe, squeezing ash can be tested by developing one kind, the multinomial constructions such as spy sand washing, set milling can be carried out again tests pipe construction
Device is highly desirable to.
The content of the invention
Pipe construction device and its construction method are tested it is an object of the invention to provide a kind of oil-water well is multi-functional, existing test is overcome
The pipe ball of testing of piping tool is difficult backwash and tested with cement injecting sliding sleeve high pressure after pipe, also needs to higher pressure and hit sliding sleeve down, easily causes
The defect of downhole safety accident, test pipe it is qualified after can continue to carry out lower step construction, without another lower operating tool string again, reduce construction
Process, guarantee construction safety, reduce production cost.
For up to above-mentioned purpose, technical solution of the invention is：
A kind of multi-functional pipe construction device of testing of oil-water well includes testing pipe ball, sliding sleeve and shear balls, and sliding sleeve is fixed on cylinder by shear pin
The position of the fluid hole of body, the two ends of cylinder are connected with the centre bore and bottom ball-and-seat of top connection respectively, test the installation of pipe ball
In the ball-and-seat of bottom, after shear balls are put into, it is seated in above the shearing ball seat of sliding sleeve upper end；The external screw thread of top connection is successively
It is connected with box cupling and short circuit, possesses liquid stream annular space between short circuit and cylinder.
A kind of multi-functional construction method for testing pipe construction device of oil-water well, be：
1. if necessary to sleeve milling construction, first packaged milling tool is connected with short circuit, the present apparatus is connected to the foot of oil pipe column,
G.I.H；
2. under to after projected depth, just pressurizeed out of oil pipe；
3. being required according to pressure testing, pass through the sealing that pipe ball verifies down-hole oil tube tubing string of testing in the ball-and-seat of bottom；
4. after pressure testing is qualified, putting into shear balls, shear balls are seated in after shearing ball seat, 5-6MPa are forced into oil pipe and cuts shear pin
Disconnected, sliding sleeve is descending to be fallen into above cover of blocking, and fluid hole is all exposed, and lower step construction is carried out as needed.
Compared with prior art, notable using effect of the invention is：The present invention verifies downhole oil by bottom ball-and-seat
The sealing property of pipe tubing string, the cylinder equipped with sliding sleeve is located at the top of bottom ball-and-seat, and cylinder is provided with fluid hole, built-in cunning
It is shearing ball seat at the top of set, sliding sleeve, testing the shear balls put into after pipe can be seated above, be so achieved that and first pass through bottom single current
Valve high pressure tests pipe, then hits sliding sleeve down by low pressure, exposes fluid hole, carries out the purpose of subsequent construction, tests pipe ball without washing out, sliding
Set only needs low pressure just can solve the problem of fluid hole exposes, overcomes existing two kinds and test Guan Fang without being hit down with higher pressure
The all defect of method, on the premise of down-hole string sealing property is ensured, facilitates subsequent construction., can be when needing set milling
It is connected before going into the well using Φ 89mm short circuit with casing section mill, testing after pipe can carry out covering milling operation；It is available when needing sand washing
The short circuit of the present apparatus is longer than the advantage of bottom ball-and-seat, can directly carry out sand washing, it is to avoid the bottom of existing instrument and fluid hole
The distance between long, defect of the sand washing without drilling depth, invalid sand washing.The present invention verifies the sealing of oil pipe using pipe ball high pressure is tested
Property, recycle input shear balls low pressure to cut the advantage of shear pin, can just complete to test pipe using one-trip string under the present apparatus, visit punching
The multinomial processes such as sand, squeezing ash, set milling, sand washing.Pipe pressure testing is tested for down-hole string using the present apparatus, its loading test effect is good, high and low
Press operation is convenient and swift.The present apparatus also can be according to the demand for testing pipe pressure simultaneously, and arbitrarily the intensity of regulation shear pin, safe and reliable.
The present invention reduces working procedure, worker's labor intensity is alleviated, production cost is significantly reduced, shorten the construction period, had
There are significant economic benefit and social benefit, with good application value.
