Description
Technical field
The present invention relates to a kind of minor diameter rock mass testing tools, specifically, being related to a kind of minor diameter rock mass hydrofracturing
Test double loop mounting rod.
Background technology
Hubbert and Willis proposes that crack caused by well bore fluid pressure break is answered with institute preservation in rock mass in nineteen fifty-seven
Power state is closely related, and points out that rock mass pressure is not at hydrostatic pressure state.Kehle（1964）Packer is isolated for the first time
The stress distribution on wellhole periphery of experimental section carried out simple analysis, and point out that the influence of packer makes hole wall periphery be formed and cuts
Stressed zone.Fairhurst（1964）It is first scientist for proposing to measure Original strata stress using hydrofracturing technology, and refers to
The plurality of advantages of hydrofracturing technology is gone out.Haimson and Fairhurst（1967）Point out the crack generated on the borehole wall with it is following
Three factors are related, 1. crustal stress, 2. the poor stress between the fluid pressure and pore water pressure of hydrofracturing；3. rock mass oozes
Saturating radial flow, these theory analysis have established the theoretical foundation of classical hydrofracturing measuring technology.Haimson（1968）
In its doctoral thesis to hydrofracturing Original strata stress measuring technology from experiment and theoretical two aspects carried out comprehensive analysis with it is complete
It is kind.The above important process is that hydrofracturing Original strata stress measuring technology has been established theoretical and experiment applied to engineering practice
Basis.The stress measurement engineering practice of real meaning is by Von Schonfeldt and Fairhurst（1970）The research of leader
What group was unfolded in a Minnesotan underground granitic mass；Then, similar answer also has been carried out in the oil fields Rangely
Power measures and research work（Haimson, 1973；Raleigh etc., 1976）.From this, Hydraulic Fracturing Stress Measurements formally enter work
Journey puts into practice field.1987 and 2003, International Society of Rock Mechanics（ISRM）All hydrofracturing In-situ stress measurements method
Recommend as a kind of main stress evaluation method, has also established the critical role of hydrofracturing In-situ stress measurements technology.
The geostress survey work of China is slightly later than foreign countries, and the fifties end, LI Si guang and professor Chen Zongji instruct respectively
Geomechanics and Three Gorges batholith workshop start.In October, 1980, the seminar led by professor Li Fangquan is in river
Northern Yi County has successfully carried out hydraulic fracturing geostress survey for the first time（Li Fangquan, 1980）, subsequent China Seismology Bureau's earth's crust answers
Power Research Institute success lightweight hydrofracturing measuring apparatus（Li Fangquan, 1981；Ding Jianmin, 1990；An Qimei, 1996；Guo
Kai is good, and 1999）.Hydrofracturing measuring technology is widely used popularization in all trades and professions of China.Up to the present, Chinese
The main hydrofracturing test method that the country uses abides by the method that International Society of Rock Mechanics is recommended.
Equipment about hydrofracturing In-situ stress measurements is broadly divided into five major class at present：（1）Heavy duty cables formula hydraulic pressure causes
In-situ stress measurements equipment is split, using Switzerland's MESY-SOLEXPERTS equipment as representative；（2）Light cable type hydrofracturing original place
Stress measurement equipment, mainly using the shallow bore hole test equipment of the CouncilforScientificandIndustrialResearch O tissue manufactures of Japanese OYO companies and Australia as representative；
（3）Comprehensive hydrofracturing test equipment, with French Cornet professors and U.S. professor Thiercelin make by hydrofracturing
Test is representative with the novel hydrofracturing test equipment that other physical prospecting mud logging equipments combine；（4）BABHY tests are set
It is standby, it is representative with northeastern Japan university professor Ito manufacture；（5）Drilling rod formula hydrofracturing equipment, is answered with China Seismology Bureau's earth's crust
The research and development manufacture of power research institute is representative.In all these equipment, minimum device diameters are the light of CouncilforScientificandIndustrialResearch O tissue manufactures
Type hydrofracturing In-situ stress measurements equipment, device diameters are Ф 36mm, are secondly the BABHY test equipments of professor's Ito manufacture,
The a diameter of Ф 48mm of testing bore holes.
Widely used measuring system is made of six parts at home, pressure fluid control system, high-pressure hydraulic pump, power
System, digital data recording system, straddle packer and high-pressure fluid transport system.This measuring system is divided into as two classes, one kind
It is the shallow bore hole for 100m, drilling rod and high pressure resistant hose can be used to supply water respectively to packer and fracturing section and realize pressure break.Separately
A kind of outer equipment is the longhole survey for 100m or more, and pressure fluid is supplied respectively to fracturing section and envelope using a switching valve
Every device, measurement system diagram is as illustrated in fig. 1 and 2.Wherein：20、30：Drilling cramp, 21：High-pressure hose, 22,32：Drilling rod is connected to test section,
23、33：Adapter, 24,34：Test section, 25,35：Packer, 26,36：Pressure sensor.
By the analysis of front it is found that diameter not yet domestic at present is less than the hydrofracturing detecting earth stress system of 40mm
System.But the hydrofracturing Original strata stress of minor diameter test system has equipment light, and low spy is required to test pressurized equipment
Point can use the high-pressure oil pump of high output pressure and annual compression system or the two-phase electricity of low discharge to pressurize.At the same time,
Requirement of the minor diameter test equipment to rockmass is low, for bigbore drilling, is surveyed according to International Society of Rock Mechanics
Examination segment length should be 6 ~ 7 times of bore diameter, then for domestic conventional 76mm 94mm geological prospecting boreholes, add
Upper packer length 1.0m or so, then 245.6cm ~ 256.4cm is at least to the length for the rockmass that drills, but for one
For the drilling of a a diameter of 48mm, it is only necessary to the rockmass length of about 99.2cm long, it is only original less than 40%,
Under identical working condition, so that it may so that amount of test data has more more than one times.At the same time, the brill that drills makes expense can be with brill
Hole aperture becomes smaller and reduces, this is greatly lowered the testing expense of Original strata stress, and the testing time of slim hole also can
Shorten therewith, so that testing expense substantially reduces.Therefore, the research and development of minor diameter Original strata stress test equipment, for pushing
Hydrofracturing In-situ stress measurements and promotion original technology upgrading innovation have important social effect and economic implications.
For minor diameter hydrofracturing test system, due to conventional hydrofracturing Original strata stress test used in drilling rod,
The fixture diameters such as high-pressure rubber pipe are excessive, downhole testing equipment can not be installed into precalculated position using original technological approaches,
