Description
Technical field
The present invention relates to Fracturing Technology fields, and in particular to the water injection well well choosing method for Fracturing Technology.
Background technique
In oil field, pressure break refers in oil recovery or gas production process, using hydraulic action, oil-gas Layer is made to form the one of crack
Kind method, also known as hydraulic fracturing.Pressure break is that stratum is artificially made to generate crack, improves oil in the flowing environment of underground, makes oil well
Yield increases, and can play an important role to improving oil well shaft bottom flox condition, slowing down interlayer and improving reservoir producing situation.Oil
After well production to certain phase, production capacity and permeability reduction improve oil well output to enhance oil extraction ability, and people invent
Fracturing Technology.The method of pressure break divides hydraulic fracturing and high enegry gas fracturing two major classes, and hydraulic fracturing is by ground high-pressure pump
For vehicle vehicle group by fluid high-speed injection well, the high pressure suppressed by shaft bottom makes reservoir rock rupture generate crack.To prevent pump truck
After stopping working, pressure decline, crack voluntarily closes up again, and in the injection liquid after formation fracture, mixing ratio density of earth formations is big
The sand of several times enters crack with fluid together, and permanently rests in crack, and supporting crack is in the open state, makes oil stream
Environment is improved for a long time.In the prior art, the pressure break within the scope of oil reservoir is mostly combined with water filling, therefore in wellfracturing
While need to arrange corresponding water injection well around.Water injection well in the prior art is mostly within the scope of oil reservoir with latticed or scattered
Shape distribution is penetrated, adjusts the development phase in later period oil reservoir, does not fully consider that different list well capacity differences, geology are poor in same block
It is different, be drilled well difference, therefore during later period Fracturing Technology water injection well addressing specific aim it is weaker.
Summary of the invention
The purpose of the present invention is to provide the water injection well well choosing methods for Fracturing Technology, to solve the prior art middle and later periods
The weaker problem of the specific aim of water injection well addressing during Fracturing Technology is realized and targetedly chooses water injection well, improves oil reservoir
The purpose of oil and gas development efficiency.
The present invention is achieved through the following technical solutions:
Water injection well well choosing method for Fracturing Technology, comprising the following steps:
(a) all oil wells within the scope of the oil field for needing to carry out Fracturing Technology are chosen, are scored every mouthful of oil well；Scoring
Parameter includes that moisture content, Liquid output, nearest oil well distance, nearest well distance, all previous fracturing effect, fracturing technology, pressure break are matched
Side, reservoir permeability, substratum production profile；
(b) scoring of all oil wells is ranked up from high to low；The higher well that sorts more is appropriate for pressure break, and at it
Surrounding arranges water injection well.
For the weaker problem of the specific aim of water injection well addressing during prior art middle and later periods Fracturing Technology, the present invention is mentioned
It is used for the water injection well well choosing method of Fracturing Technology out, this method to choose the institute within the scope of the oil field for needing to carry out Fracturing Technology first
There is oil well, scores every mouthful of oil well；Grading parameters include moisture content, Liquid output, nearest oil well distance, nearest well away from
From, all previous fracturing effect, fracturing technology, pressure break formula, reservoir permeability, substratum production profile；By the scoring of all oil wells from
It is high to Low to be ranked up；The higher well that sorts more is appropriate for pressure break, and water injection well is arranged around it.Process provides one
The method that water injection well selects well during a scientific and reasonable Fracturing Technology for the later period solves the increasing of prior art middle and later periods pressure break
The weaker problem of the specific aim of water injection well addressing during note can be to oil field residue by water injection well selected by this method
Tremendous contribution is made in the exploitation of reserves, so that closing on oil well output obtains huge raising, every mouthful of water injection well can be played greatly
Effect, therefore radial or latticed water injection well hole pattern has substantive distinguishing features outstanding and shows compared in traditional technology
The progress of work.
The weight of parameters in the grading parameters are as follows: moisture content 36%, Liquid output 33%, nearest oil well distance 8%,
Nearest well distance 7%, all previous fracturing effect 3%, fracturing technology 5%, pressure break formula 5%, reservoir permeability 2%, substratum produce
Liquid section 1%.
It further include choosing the metastable oil well of a bite yield to be used as with reference to well, setting is with reference to grading parameters every in well
Are as follows: moisture content 36 divides, Liquid output 33 divides, nearest oil well distance 8 is divided, nearest well distance 7 is divided, all previous fracturing effect 3 divides, pressure break
Technique 5 is divided, 5 points of pressure break formula, reservoir permeability 2 divide, substratum production profile 1 divides；Every grading parameters of remaining each oil well are equal
Equal proportion calculating is carried out by standard of the parameter with reference to well.
The fracturing technology includes conventional pressure break, small sand amount pressure break, large sand amount pressure break；The score of its medium and small sand amount pressure break is
The half of conventional pressure break score, the score of large sand amount pressure break are one times of conventional pressure break score.
Compared with prior art, the present invention having the following advantages and benefits:
The present invention is used for the water injection well well choosing method of Fracturing Technology, during solving prior art middle and later periods Fracturing Technology
The weaker problem of the specific aim of water injection well addressing can open oil field remaining reserves by water injection well selected by this method
Break out tremendous contribution out, so that closing on oil well output obtains huge raising, every mouthful of water injection well can play very big effect, therefore
Compared in traditional technology, radial or latticed water injection well hole pattern has substantive distinguishing features outstanding and significant progress.
