Description
Technical field
The invention belongs to oil-gas field development pressing crack construction Material Field, specifically relate to a kind of pressure break modified fibre and preparation technology.
Background technology
The conventional fracturing technology existence high speed row of returning and proppant backflow affect the contradiction that gas well is normally produced, particularly in gas reservoir development process, have a large amount of high pressure high gas rate wells, these high pressure high gas rate well proppant backflow problem of shaking out is more outstanding, during discharge opeing after pressure, production test and adopt initial stage (the about 1-3 month) of gas transmission, have an appointment 50% well (layer) there is proppant backflow in various degree, proppant backflow amount is generally at 1m
3within, minority well is more than 1m
3, even reach 3m
3.Because gas well pressure is high, output is high, flow velocity is fast, the hazard ratios such as proppant backflow is shaked out quite strong to the erosion attack effect of well head and ground flow pipeline gate valve, ground installation, the sand thorn erosion attack of generation are larger.Gas well shakes out and reduces bubble row technological effect, reduces the production time efficiency of gas well, rate about 0.5% when estimating to affect gas well liquid loading because shaking out, and has had a strong impact on the normal production of gas well, and there is serious potential safety hazard.
For the problems referred to above, domestic and international new development fiber fracturing technology, it forms space net structure by the interaction between fiber and proppant and provides support cohesive force extra between agent and crack, thus proppant is stabilized in home position, and fluid can freely pass through.After fracturing fluid starts the row of returning, due to washing away of fluid flowing, just there is plasticity shearing deformation in proppant particles, forms a series of domes; The fiber axial force that during discharge opeing, the detrusion of sand arch is brought out can resist the detrusion of sand arch, thus improves the stability of sand arch and critical discharge speed, is conducive to controlling returning of proppant and tells; Fiber does not interact with fracturing fluid, and to the not requirement of temperature, pressure and closed-in time.Can discharge speed be improved after pressure, shorten the row's of returning time, improve the row of returning and lead.
For ensureing that fiber fracturing technology is constructed smoothly and will obtain better effects, pressure break fiber should possess in clear water and have in the fracturing fluid base fluid of viscosity and have preferably from dispersibility, fiber forms spacial framework thus reaches auxiliary outstanding sand ability in dispersion process, fiber itself needs to have the requirements such as certain size, diameter, density and tensile strength simultaneously, should not have a negative impact in addition as performances such as crosslinked for fracturing fluid, the broken glue of material for pressing crack construction.In fiber fracturing construction fiber surface property can on its dispersiveness in fracturing fluid, whether form network structure and make a significant impact, current conventional fibre can not meet above-mentioned requirements, therefore need to carry out surface modification to it, through retrieval, there is not the relevant report of pressure break fiber being carried out to surface modification.
