Description
Technical field
The present invention relates to oil field development technical field, particularly fracture in oil and water wells proppant technology field, is specifically related to one
Plant and prepare the new method from suspension haydite.
Background technology
Fracturing is one of key technology that low-permeability oil deposit improves oil recovery factor the most both at home and abroad.Fracturing is
Refer to by ground high-pressure pump group, the fracturing fluid with certain viscosity is clamp-oned well exceeding well over the discharge capacity of stratum maximum imbibition ability
In, suppress high pressure in shaft bottom immediately.Fracture pressure and the maximum anti-tensile of surrounding rock on stratum near the borehole wall is exceeded when this pressure
After intensity, stratum will produce near shaft bottom crack not of uniform size.Continue in well, clamp-on the pressure break carrying proppant
Liquid, crack continues to extend forward and insert proppant in seam under strong pressure.After termination of pumping, fracturing fluid is at gel breaker
The lower rapid break of effect also returns and drains into ground, and proppant continues to stay in seam, thus can form one or many in the earth formation
Bar has certain altitude, length, width, has the supporting crack of high flow conductivity simultaneously.This supporting crack possesses higher oozing
Ability, is remarkably improved the flow conductivity of oil reservoir, makes crude oil successfully be passed through producing well, thus reach the mesh of oil well production increasing thoroughly
's.
The most conventional petroleum fracturing propping agent has: quartz sand, alundum goods and haydite.Wherein ceramsite propping agent tool
There is raw material sources extensive, product strength advantages of higher, become the conventional use of fracturing propping agents of oilfield in recent years.Consider
To bulk density (the generally higher than 1.6g/cm that haydite is bigger3), so height need to be added in pressing crack construction process in fracturing fluid
The thickening agent (such as water soluble polymers such as guanidine glue, celluloses) of concentration increases himself viscoelasticity thus Effective Suspension taking
Band proppant.But add high concentration thickening agent and can bring the problems such as pressure break cost is high, reservoir damage is serious.
If can tradition pressure break haydite be prepared as from the haydite suspended, then in pressing crack construction process, it is not necessary at fracturing fluid
Middle interpolation thickening agent, available clear water replaces tradition high viscosity fracturing fluid, and then saves dosing process and the equipment of conventional pressure break.With
Time, the removal of thickening agent also will significantly reduce pressure break to the injury of reservoir and pressure break cost.
In recent years, the method for the conventional polymer overmold haydite such as phenolic resin or epoxy resin prepares from suspending film-coated ceramisite
Finished product, but injecting behind stratum from suspension haydite that said method is prepared, under the clossing pressure that stratum is huge, haydite surface
Resin mutual adhesion can become hard resin mass, and then blocking supporting crack, affect the flow conductivity of oil reservoir, causes crude oil difficulty
To be passed through producing well smoothly, oil recovery factor also decreases.
Therefore, select more effective way haydite is prepared as in clear water can from suspend haydite, thus improve its
Application in terms of oil field compression fracture has epochmaking actual application value.The present invention is therefore.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of new method prepared from suspension haydite, system
From suspension haydite can suspended dispersed in clear water, can solve existing to hold when oil field compression fracture is constructed from suspended prop simultaneously
The problem easily blocking supporting crack.
