Description
Technical field
The present invention relates to a kind of cased hole completion multistage pressure break horizontal well machinery searching pipe column and its groundwater prospecting method, belong to oil field
Oil recovery technique field.
Background technology
Using horizontal wells low permeability oil field can largely suggestions for improvement, improve recovery ratio.Horizontal well has
There is the well completion interval longer than straight well, oil well output is improved by expanding oil reservoir drainage area, can be up to straight well yield
It is more than three times.However, because the well track and flooding pattern of horizontal well itself are complicated and changeable, each oil reservoir lithology, physical property and storage
The property of layer fluid is different, horizontal well is existed in terms of the water absorbing capacity of each interval, water-front advance velocity and production liquid condition
Difference, indivedual interval water breakthroughs are early, and water bearing bed position and direction are indefinite, and each layer production capacity and pressure condition are unclear.Due to horizontal well
Water detection technology it is still immature, particularly the water detection technology of the low liquid measure horizontal well of low-permeability oil deposit is also in exploratory development rank
Section, causes live dynamic regulating measures without specific aim, has a strong impact on the development effectiveness of horizontal well.
At present, it is general that each pay interval is opened using hydraulic packer sealing card, rod-type oil extraction pump is connected to testing tube
On post, extraction operation is carried out to pay interval in underground.However, because High water cut and the mostly fouling of water logging horizontal well are serious, liquid
After pressure type packer setting, rod-type oil recovery pump piston and sucker rod can not be smoothly in tripping in pump barrels, Y441 Bidirectional anchor packers
Unsealed in horizontal segment difficult；If Y341 packers are used alone, tubing string is easily wriggled in pumping process, influence tubing string sealing.
The content of the invention
It is an object of the invention to provide a kind of cased hole completion multistage pressure break horizontal well machinery searching pipe column and its water detection side
Method, Reliable guarantee is provided for the water-control oil-increasing measure of horizontal well.
The particular technique content of this cased hole completion multistage pressure break horizontal well machinery searching pipe column is as follows：
The plug of this searching pipe column end is sequentially connected the first intelligence being located in horizontal well horizontal segment by oil pipe upwards

Water is located at by oil pipe connection above device, the 3rd Y341 hydraulic packers and the 4th intelligent switch device, the 4th intelligent switch device
Y221 mechanical packers in horizontal well vertical section, Y221 mechanical packers are sequentially connected screen casing, whole cylinder pump and are located at upwards
Sucker rod in oil pipe.
The groundwater prospecting method of this cased hole completion multistage pressure break horizontal well machinery searching pipe column is as follows：
By this searching pipe column G.I.H assembled, above carry and transfer tubing string, the Y221 set in straight well section is mechanical
Packer, the whole tubing string of grappling；Oil jacket applied pressure by annulus is carried out from well head, hydraulic pressure enters oil pipe through screen casing, sets each Y341 hydraulic pressure
Formula packer；Tripping in sucker rod, turn on pump production, each intelligent switch device is performed according to pre-set programs and closed and breakdown action, is carried out
The production of an interval sometime, completes well head list amount, aqueous and production capacity sampling monitoring；After test terminates, above carry and applying
Work tubing string, deblocking Y221 mechanical packers and each Y341 hydraulic packers, act this searching pipe column.
Searching pipe column of the present invention can realize that operating tool string and flow string are once completed, and technical process is simple and safe reliable,
It is capable of the test of production capacity, pressure and the temperature of one-trip string completion each interval of horizontal well, specifies water exit interval and water flow, be
The water-control oil-increasing measure of horizontal well provides reliable foundation.
