Description
Technical field
This utility model relates to the fracturing fluid in oilfield prospecting developing field and reclaims field, is specifically related to a kind of fracturing fluid and reclaims fluid erosion prevention desanding system.
Background technology
Pressing crack construction operation is contemplated to transform oil-gas Layer, improves flow conductivity, makes oil-gas Layer possess exploit condition, is a kind of oil gas field yield-increasing technique measure, and substantially every mouthful well will carry out fracturing work；Along with horizontal well and the development of volume fracturing Technology, the substantial amounts of surface water of demand；Because fracturing fluid adds the proppant of substantial amounts of additive and high intensity, in well, after pressure, return the liquid recycling to be carried out of discharge, otherwise, when it discharges on the ground, surface water and environment can be brought up and pollute.It is no matter the discharge of fracturing fluid, or recycling, initially encounter is reducing pressure by regulating flow, the erosion problem of formation.
1., after pressing crack construction, before closing well discharge, in well, there is certain pressure, under regular situation, the scope of pressure 10-35MPa to be reached；The particularly termination of pumping shut-in pressure of high-pressure gas well is most at about 40MPa.
2., during well inner high voltage liquid outwards returns out, carry a certain amount of proppant, such as sand, haydite etc..When bleeding off pressure, it is impossible to completely head valve is opened, during in order to avoid big quantity of fluid returns out, the proppant added in well is returned and ejects, it is necessary to control with flow less than 1 side/point flow velocity, to exterior liquid.Therefore, reducing pressure by regulating flow measure to be taked.When in well, liquid, after reducing pressure by regulating flow, is up to more than 100 meter containing sand flow body by the flow velocity of reducer, be equivalent to the abrasive machine of high speed rotating cutting, when the body Han sand flow at a high speed touches tube wall, tank skin, during the metal surface such as bend pipe, will soon pierce through；Underground work company to pay a high price for changing throttling open flow pipe fitting every year, and to spend more work time cost, delays construction and produces.
3. formation high speed liquid stream during stratum partial high pressure throttling open flow after pressing:
Pressing crack construction stratum to be injected tens is to the sand of hundreds of side, the liquid of thousand of sides；Strata pressure is spread after can not sucking these liquid in time by stratum, forms high-pressure area, be reflected on well head, just have certain well head pressure around shaft bottom；And the liquid on these press-in stratum to be discharged outside well in time, otherwise, fracturing fluid will result in injury；And during discharging fracturing fluid, the flow of returning fluid's body is controlled, otherwise, a large amount of sands on press-in stratum can return out outside well together with liquid, makes the crack closure pressed off, and does not reaches the effect on transformation stratum.The most on-the-spot mode using reducer controls to bleed off pressure.Size according to well head pressure and the change of pressure during bleeding off pressure, generally control open flow flow be 1 side/point in；It is respectively adopted the reducer open flow of a diameter of 6,8,10,12mm.
4. at a high speed containing sand flow body manifold of ground is caused erosion:
Swiftly flowing containing sand flow body, when flowing through metal surface, or when sand grains impacts at a certain angle, metal body can be formed erosion, it is similar to abrasive wheel cutting machine；When the flow velocity of sand grains is the biggest, the erosion effect to metal is the strongest；The rate of flow of fluid containing sand flow mostlys come from the energy of the intrinsic pressure rear accumulation of well, the process of discharge liquid, is also the process of well self-energy release.The water-horse power that the body containing sand flow produces in discharge process, should be the product of flow and pressure, and the energy discharged by a period of time should be the product of power and time.If well head pressure is 30MPa, well includes containing sand flow body stream, carries out the quartz sand that proportion is 1.62, when reaching 1 side, can be calculated by preservation of energy, 1 side's sand discharges the electric energy of about 1.33 degree, when the biggest energy, when continuing a certain pipeline section of erosion or a certain position, then this position will soon be pierced, such as valve, pipeline section, chamber wall etc..
It addition, during gas well carries out gas-liquid two-phase separation, the liquid outlet of separator, it may appear that gas-liquid, with the phenomenon gone out, ceaselessly will carrying out switch and the adjustment of vapour-liquid valve on separator, if there being misoperation, having the risk that separator explodes；Separator is just to use containing during a small amount of gas in gas, seriously limit the use of separator, cause in gas-liquid with when going out, use the mode in clean-up pit ignition to carry out discharge opeing, seriously limit the use of separator, bring great hidden danger to the safety and environmental protection in terms of gas well discharge opeing.
