Study on composite sand control technique of reticular cementation in thermal recovery well

In the composite sand control technique of reticular ce- mentation in thermal recovery well,the fiber cementation sand and network agent are added into sand carrier to fill the reservoir without removing lines.In the filled stratum,the mechanical equilibrium is reached due to the interaction be- tween the contact pressure and friction force to form network fibers,and sands are blocked to discharge back.The keys of the composite sand control technique of reticular cementation in thermal recovery well are the screening superior fiber and network agent,and the establishing of the matching techni- cal flow,so the fiber should have both excellent mechanical strength and favorable dispersion.Application shows that the technique is superior in good sand control effect,little harm for stratum,which is of great advantage to output of oil well.
