In the technical proposal, a plastic expansion casing pipe body (11) and grooves (12) are used; the wall of the plastic expansion casing pipe body is provided with one or more than one though groove; a high-strength plastic expansion casing pipe is used to replace a steel sleeve; a man-made cement pore wall with the plastic expansion casing pipe is formed in a pore section in need of wall protection to prevent collapse, water leakage, water burst and chipping and ensure continuation of the next step of drilling operation.The invention solves the problem that great drawing force ranging from 10 tons to 15 tons and complicated expansion tools are needed when steel expansion casing pipes expand; by using the high-strength plastic expansion casing pipes, fast, reliable and low-cost hole drilling and wall protection can be realized without expansion tools; all holes can be drilled at one caliber, therefore drilling efficiency can be greatly improved.
Description
Technical field:
The present invention relates to a kind of method and special-purpose expansion sleeve that carries out borehole wall-protection with the plastic expansion sleeve pipe, belong to used for geological prospecting drilling technology field.
Background technology:
The expansion sleeve breast wall technology is used for the bad ground hole section that geological drilling is holed.Conventional breast wall technology is to adopt mud as flushing liquor; in the drilling process, form the mud skin of thin layer at borehole wall, prevent that the moisture in the flushing liquor from constantly permeating to borehole wall; cause the expansion on stratum or collapse, mud can be protected the porosity permeability formation as flushing liquor.But the large or broken formation for the crack, just adopt the way that is lowered to steel sleeve, the broken creviced formation of packing, guarantee normally to creep into, add gun drilling, but the problem of bringing is: next joint steel sleeve bore diameter will dwindle one-level, as meeting bad ground not only but also need lower one deck sleeve pipe, one-level is dwindled again in boring, the core diameter that too little bore diameter obtains is also little, too little core diameter can not meet the requirement of geology standard, so boring can not unrestrictedly be lowered to steel sleeve, otherwise boring will be scrapped.The research unit of each probing, production unit is done a little little adjustment at the additive of mud fluid, by in mud fluid, adding inert material, dilatancy particle etc., stop up little crack and hole, reduce leakage and the stable hole wall of borehole wall, the purpose of said method all is for better retaining wall, but all can not be fundamentally the effect of borehole wall-protection be significantly increased.The expansion sleeve technology also is in the Preliminary Exploitation stage abroad in recent years, only have several the multinational petroleum corporations such as Weatheford, Enventure carrying out the R﹠D work of this respect, develop simultaneously expansion steel sleeve and steel sleeve instrument, mainly contain anti-bloat tool and two kinds of the rotation bloat tools of drawing of solid-cone, all need powerful pulling force 10-15 ton, and needing complicated bloat tool, geology rock-core borer ability is generally less than 10 tons pulling force, can't adopt the steel expansion sleeve.
Summary of the invention:
The object of the invention provides a kind of method and special-purpose expansion sleeve that carries out borehole wall-protection with the plastic expansion sleeve pipe, adopt highstrenghtpiston's expansion sleeve, need not cooperate bloat tool, can realize fast, reliably, matter borehole wall-protection cheaply, with a bore that borehole drilling is complete, improve drilling efficiency, solve the problems referred to above that exist in the background technology.
Technical scheme of the present invention is: a kind of method of carrying out borehole wall-protection with the plastic expansion sleeve pipe comprises following processing step:
A, by the diameter of being holed, configure the plastic expansion sleeve pipe;
B, in the bottom of plastic expansion sleeve pipe, the plastic sheath pipe shoe is installed, carry out shutoff, the material of said plastic expansion sleeve pipe, plastic sheath pipe shoe is the highstrenghtpiston, said highstrenghtpiston selects in the prior art intensity high plastics of trying one's best;
C, be connected with drill steel on the top of plastic expansion sleeve pipe;
D, use reaming bit, will need the hole section of retaining wall to enlarge the aperture, form the hole wall shoulder;
E, will connect drill steel, plastics pipe shoe and plastic expansion sleeve pipe and be lowered to and need the hole of retaining wall section, and the plastics pipe shoe is sitting on the shoulder of hole wall securely;
F, with rig feed oil cylinder pressurization, plastic bushing is longitudinally expanded, be expanded to the hole wall that reaming bit has enlarged;
G, with slush pump cement paste is pumped in the plastic expansion sleeve pipe along drilling rod, cement paste flows into the hole section that needs retaining wall by the plastic expansion sleeve pipe, and is penetrated in the crack of hole wall and goes, and cement paste, hole wall and plastic expansion sleeve pipe three are fixed together;
H, etc. the cement solidifies, bored cement plug after, need retaining wall hole Duan Chu, forms an artificial hole wall with the plastic expansion sleeve pipe, can be anti-collapse, preventing water leakage, prevent Chung water, anti-lost, finish borehole wall-protection.
Said plastic expansion sleeve pipe, before use, first at several grooves of plastic expansion sleeve pipe side opening; The quantity of opening groove is arbitrarily, and opening groove shape is rectangle, dove-tail or combination.
Said is 2-5Mp with slush pump along the pressure of drilling rod pump cement paste, and the pressure that rig feeds oil cylinder is the 1-5 ton.
A kind of special-purpose expansion sleeve that carries out borehole wall-protection with the plastic expansion sleeve pipe comprises plastic expansion sleeve pipe body and groove, and the wall of plastic expansion sleeve pipe body is provided with one or more grooves.
Said groove quantity is arbitrarily, is shaped as rectangle, dove-tail or combination.
The material of said plastic expansion union body is the highstrenghtpiston, and said highstrenghtpiston selects in the prior art intensity high plastics of trying one's best.
The invention has the beneficial effects as follows: the present invention has overcome needs very high pulling force 10-15 ton when the steel expansion sleeve expands, and the bloat tool problem of the complexity that will join, adopt highstrenghtpiston's expansion sleeve, need not cooperate bloat tool, can realize fast, reliably, matter borehole wall-protection cheaply, with a bore that borehole drilling is complete, improved greatly the efficient of probing work.
