Abstract
The method using ground high energy gas to carry out reservoir reconstruction of the present invention belongs to oil and gas reservoir fracture technology field, the equipment that the method uses high energy air stream drives proppant to import underground fracture stratum realizes, this equipment is erupted mechanism by high energy gas, jet mechanism, high energy gas jet mixing mechanism, measurement and control instrument and guide duct combine, measurement and control instrument controls high energy gas and erupts mechanism's igniting eruption high energy gas, jet mechanism jetting stream, and make both generate the guide duct arrival target formation alignment preforation tunnel injection of mixing pressure break medium entrance down-hole in mixed organization, target formation is made to produce more than 3 cracks and make proppant enter cracking initiation support, it is beneficial to oil-gas mining and production；This method is independent of water resource, pollution-free to reservoir, controls at ground precise manipulation, and pressure break scale is unrestricted, provides a kind of new concept for reservoir reconstruction, uses fracturing stratum equipment reliable effective, and this method and apparatus is worth using and promoting.
Description
Technical field
Employing ground disclosed by the invention high energy gas carries out the method for reservoir reconstruction and belongs to oil and gas reservoir pressure break and change
Make technical field, particularly relate to a kind of use ground to produce high energy air stream drives proppant fracturing stratum
Special method.
Background technology
Fracturing technique be a kind of for reservoir reconstruction with improve yield professional technique.Use ground high energy gas
The method carrying out reservoir reconstruction is a kind of brand-new fracturing process, and this fracturing process is based on high energy air stream drives
Proppant imports the equipment on underground fracture stratum and realizes.Use the method that ground high energy gas carries out reservoir reconstruction
Have: 1. the ground of hydraulic fracturing method can control frac pressure the most in real time；2. can carry proppant to make
While target formation forms crack, proppant can enter crack fracture and form support, strengthens flow conductivity
Advantage；Avoid the most simultaneously fracturing can only target formation formed one by crustal stress control bigger
Major fracture so that the communication area of target formation and production casing is big not, is unfavorable for the big of ore bed resource
The drawback of amount exploitation.It is to use high energy gas additionally, due to the method using ground high energy gas to carry out reservoir reconstruction
Body drives proppant to form mixing pressure break medium reservoir is carried out pressure break, it is to avoid the waste of substantial amounts of water resource
With pollution.
The method using ground high energy gas to carry out reservoir reconstruction has drawn high energy gas based on underground fracture bullet
The pressure of body fracturing process rises fast, can reservoir along preforation tunnel formed not by crustal stress control a plurality of relatively
Large fracture, links up more dry, thus increases Oil/gas Well reservoir mineral resources and link up face with production casing
Long-pending advantage.Simultaneously because use ground high energy gas to carry out the generation of high energy gas in the method for reservoir reconstruction
Carrying out on ground, pressure break scale can be controlled according to actual needs, is not affected by down-hole small space.
The ground high energy gas that uses of the present invention carries out the method advantage of reservoir reconstruction a lot, can be to high energy gas
Stream, proppant etc. accurately control, and this provides a kind of novel fracturing stratum for well fracturing construction
Special method.
Summary of the invention
It is an object of the invention to: the method providing this employing ground high energy gas to carry out reservoir reconstruction to society,
The equipment that this method uses high energy air stream drives proppant to import underground fracture stratum realizes, and this equipment is
Ground is used to produce the special equipment of high energy air stream drives proppant fracturing stratum.
The technical scheme is that such: the method that this employing ground high energy gas carries out reservoir reconstruction
The equipment using high energy air stream drives proppant to import underground fracture stratum realizes, described high energy air stream drives
Proppant import underground fracture stratum equipment by high energy gas erupt mechanism, jet mechanism, high energy gas with
Jet mixing mechanism, measurement and control instrument, ground and down-hole guide duct combine, and technical characterstic is: institute
The high energy gas of the equipment stating the fracturing stratum of employing erupts mechanism, jet mechanism, high energy gas and jet to be mixed
Close mechanism and measurement and control instrument is respectively provided with on the ground, control high energy gas by measurement and control instrument and erupt mechanism's igniting
Eruption high energy gas, control jet mechanism jetting stream and control high energy gas and the jet of eruption at high energy
Gas generates with phase separation in jet mixing mechanism and mixes pressure break medium entrance down-hole guide duct, leads in down-hole
In skirt road, the formation of mixing pressure break medium is suppressed high energy and containing proppant air-flow and is arrived fracturing stratum position, down-hole
Guide duct screen casing mouth alignment pit shaft target formation preforation tunnel, measurement and control instrument by temperature, pressure,
Flow, the parameter of micro-seismic sensor real-time testing fracturing process, Based Intelligent Control high energy air stream drives proppant to
Preforation tunnel sprays, and makes target formation produce 3 and above relatively large fracture, and makes proppant enter crack pair
Cracking initiation supports, and increases exploitation and the production of the communication area of target formation and pit shaft, beneficially oil gas.
