Description
Technical field
It is that thick bridge plug is stifled in a kind of molten type mineral fibres of acid the present invention relates to oilfield exploration drilling auxiliary agent technical field
Leak agent and leakage-stop liquid and preparation method thereof.
Background technology
The generation of leakage brings extreme difficulties to the exploration and development of petroleum resources, it can not only expend drilling time, loss
Mud, and be possible to cause a series of complex situation such as bit freezing, blowout, well slough, wellbore can be caused to scrap when serious, cause weight
Big economic loss.Leakage can be summarized as to being endangered caused by oil-gas exploration, drilling well and development operation：1. leakage delay is bored
The well operations time extends drilling period；2. leakage directly contributes huge goods and materials and economic loss；3. reservoir leakage can damage production
Layer；4. interfering geological logging work；5. leakage interferes the conventional maintenance processing of mud property；6. leakage can cause underground complexity feelings
Condition.And leakage prevents mainly to use five class measures：Rational well structure design；Reduce wellbore pressure；Wellbore pressure is reduced to swash
It is dynamic；Drilling fluid following drill leakproof；Under balance pressure drilling.Rational well structure design is to prevent the most important link of leakage.Planned well
When body structure, it is necessary to according to formation pore pressure, fracture pressure, caving pressure and leakage pressure section, make as far as possible same naked
Equivalent drilling fluid density meets blowout prevention, anti-collapse, leakproof requirement simultaneously needed for eye well section.Due to being limited by casing program, when
When above-mentioned condition can not meet simultaneously, then setting of casing is answered to separate on low fracture pressure stratum with high pressure zone so that same open hole well
Duan Suoxu drilling fluid highest equal yield densities are less than formation fracture pressure, prevent the generation of pressure break leakage.Because of bridging materials used
Difference, so there are many bridge joint sealing agent preparation method, presently describe several common bridge plug agent:
1. shell slag-polyacrylamide drilling fluid:It can leak stopping, and de-plugging can be acidified, be conducive to protect oil-gas Layer,
Good effect is achieved in the biogenic limestone of fracture development.Gluey polyacrylamide dosage be drilling fluid volume 1% to
1.5%, cement (or other polyvalent metal compounds) dosage is the 0.5% to 1% of drilling fluid volume.Shell slag (removes after shell roasting
Removing the residue of firing fine powder) dosage is the 3% to 5% of drilling fluid volume, size distribution is：0.075mm to 0.5mm accounts for 20%,
0.5mm to 5mm accounts for 20%, 5mm to 15mm and accounts for 60%, when preparation, first in polyacrylamide and cement addition drilling fluid, uses drilling well
Liquid rifle is made a spurt or is stirred with blender, is uniformly mixed, drilling fluid viscosity is made to rise to 50s or more, shell slag is then added, then mix
Uniform, injection drop ply position is closed, with the leakage of drilling fluid, visible plugging effect soon.
2. flexible leak stoppage agent:The compoundings such as rubber granule and modified asbestos, scurf are added in drilling fluid, and wherein micelle, which rises, builds bridge
Effect, modified asbestos and scurf play filling and solidification, because rubber granule density is in 1.17 g/cm3To 1.27g/cm3Between, energy
It is enough evenly dispersed in drilling fluid, and the substances such as the clay in drilling fluid can be adsorbed and form one layer of adsorbed film, have centainly
Cementation.Micelle is flexible, is easily accessible smaller crack, and micelle is in irregular polyhedron, can be generated with slotted wall compared with
Big frictional force, it is very effective that this sealing agent tackles fractured leakage.When use, micelle granularity should be selected according to fracture width,
Micelle more than slit width should account for 40% to 50%, and the micelle for being equivalent to 1 to 1/2 times of fracture width accounts for 10% to 20%, less than splitting
It is proper that the micelle that 1/2 times of slit width degree, which accounts for 30% to 40%, it, which is formed by tamper not only, certain intensity, and
It is dense.In addition there is a kind of sealing agent of asphalt type, name of product is OP-1, and 160 DEG C of softening point, particle is irregular
Body, can account for 90% by the particle that 60 mesh are sieved to 200 mesh, not soluble in water, but can be dispersed in water well.OP-1 particles are soft
Change or less has certain intensity, into after drop ply, forms bridge joint skeleton, and then form bed course and mud cake, plays filling and bridge
The effect of leak stopping layer.OP-1 blocking agents have plasticity, can enter the crack less than particle size, when downhole temperature is close to softening point,
Particle deformation, it is coatable on the borehole wall, fine and close and tough and tensile mud cake is formed, not only can be with leakproof, but also it can be anti-collapse.
3. intumescent sealing agent:Type is also very much, and onsite application is mainly the following:
(1) polyurethane foam varicosity sealing agent:The characteristics of polyurethane foam varicosity (PAT) particle sealing agent be water suction after from
Body product can expand rapidly.Observe under the microscope, PAT be netted connectivity structure, grid by 0.1~0.2mm of diameter twine
It constitutes, eye diameter is 0.4~0.5mm, has good elasticity and intensity.Due to its heap in hole, one is formed
Infiltrative interval, while its grid can trap various particles and form fine and close mud cake therebetween and leak stopping work to fill
With.(2) TP-1090:TP-1090 is reacted with polyacrylamide by inorganic metal salt, is solid granular object, normal
Under temperature, 40 minutes start water swelling, after 6 hours, may expand up to 50 times.After the blocking agent enters drop ply, water swelling
Block drop ply.(3) SYZ dilatancy sealing agent:It is a kind of high molecular polymer, there is very strong water swellability, can absorb certainly
The water that 50~60 times of body weight, water swellability occur mainly in first 30 minutes after being contacted with water, therefore are leaked entering
Before layer, the agent cannot be allowed to be in direct contact with water, that is, which cannot directly be carried with water-base drilling fluid.Use the agent
Shi Bixu takes a three-stage approach, the first step, and it is in place to drop ply to carry the agent with water-in-oil emulsion;Second step is injected containing demulsifier
Liquid passes through leakage channel, and the intrapore water-in-oil emulsion of bridge plug is displaced.In order to give full play to the work of demulsifier
With answering intermittent driving, demulsifier and water-in-oil emulsion made to have sufficient time of contact and contact area.Third walks, and is inhaled in SYZ
It after water expansion, then is squeezed and is blocked up with drilling fluid, solid colmatation zone can be formed.
Compound leakage stop agent:I.e. by the rigid particles of different-grain diameter, flexible particle, fibrous matter, flaky substance by certain ratio
Example mixing is added high glue and cuts in the drilling fluid of high dehydration, is pumped to drop ply position leak stopping.Because after leakage, we are difficult to determine
The property of drop ply, if fractured leakage, fracture width will not be uniform, and the applicable model of mixed type sealing agent
It is that comparison is extensive to enclose, and rigid particles are first in duct bridging, followed by fibrous matter, flaky substance and special small clay particles
It is filled, forms solid blocking substance.Typical compound leakage stop agent can be enumerated following several:(1) rubber granule is compound stifled
Leak agent:Rubber granule 35%, walnut shell 20%, oyster shell whiting 15%, sawdust 10%, cotton seed hulls 12%, peanut shell 5%, straw 3%.(2) HD bridges
Connect sealing agent:Walnut shell:Mica:Rubber granule:Monofilament:Vermiculite:Cotton seed hulls:Sawdust=3:2:3:0.1:2:1:1.(3) FDJ is compound
Sealing agent:Be using inertia hard blocking material as primary raw material, using inorganic salts as reinforcing agent, using polymer as synergistic agent, optimum ratio
It forms.The agent is divided into three kinds:There is the FDJ-1 for adapting to small leakage speed, the FDJ-2 of speed is leaked in adaptation and adapts to the FDJ-3 of big leakage speed.Add
The FDJ-1 for entering 5% to 8% (weight and volume ratio) can block up the cracks below 2mm, and 5% to 10% FDJ-2 is added and can block up 2mm to 5mm
Crack, 5% to 12% FDJ-3, which is added, can block up the crack of 5mm to 10mm.(4) 915,917 compound leakage stop agents:915 compound leak stopping
Agent by 30% walnut shell, 45% cotton seed hulls and sawdust, 25% vermiculite and mica sheet assemble.917 compound leakage stop agents by
20% walnut shell, 15% rubber granule, 15% cotton seed hulls, 20% sawdust, 15% vermiculite, 15% mica sheet assemble.
(5) cotton seed hulls ball sealing agent:By 50% cotton seed meal, 31% cotton seed hulls, 1% velveteen, 18% bentonite and 0.1% surface
Activating agent (such as trimethyl ether of ethylene oxide, propylene oxide, polyethylene glycol) is uniformly mixed, and is heated with steam in tube furnace
To 100 DEG C to 160 DEG C, then the mixture after heating is compressed, diameter 6.3mm, long 6.3mm are squeezed into extremely with pellet processing machine
The pill of 25.4mm, in case using.When boring chance lost-circulation zone, 10% to 25% cotton seed hulls ball is added in drilling fluid, is pumped into drop ply,
After a period of time, cotton seed hulls ball absorbs a large amount of moisture content, causes to expand and divide, blocks drop ply.Though the above bridge plug blocks up building agent
Can also so be played in drilling well prevents leakage, but it prepares complicated, takes time and effort, can not general warranty high temperature resistant, high pressure and
High acid-soluble ratio.
