Application of styrene butadiene latex in well cementing of oil and gas fields

Why cement?

Crude oil production is a complicated process, in this complex needs to be solved in the process of drilling, well cementing, perforating (fracture) problem such as water injection. Solid and refers to the annulus between casing and formation with the construction process of cement effectively suppressed, the cementing quality directly affect the production of oil and gas Wells and oil and gas field development. If the cementing quality is not good can cause the formation of colluding, getting in the way of slicing, layered water injection, production technology, such as, if colluded with civil Wells, will also cause pollution. Good cementing quality, Can effectively cut off oil and gas collusion between different strata, improve the recovery efficiency of oil and gas.

The superiority of the cementing with SBRL
SBRL class mechanism of fluid loss agent, colloidal particles between congestion in cement filling particles, reduce the filter cake permeability, and part of the colloidal particles under the action of pressure difference between the cement particles gathered film-forming further lower the permeability of the filter cake, which ensure the slurry pump injection of liquidity and efficiency. SBRL class fluid loss agent used in cement slurry, cement slurry in the conventional performance is better than that of virgin pulp, has obvious rapid hardening, early strength, low water loss and right-angle thickening, not only can ensure the slurry dynamic water retention, and improve the cement ring and bonding performance between the casing and formation. Cementing with latex superior cementation performance, you can minimize ring gap between cement annulus and formation, casing, and reduce the cement ring and cracking dry sand hole, and the rheological properties of the latex cement slurry is superior, and can effectively avoid the happening of gas channeling phenomenon. Another latex cement cement ring can endowed with toughness, improve the dynamic mechanical properties of cement obviously, improve the cement ring resistance to perforation (fracturing, etc.)

Another latex cement with a density and low permeability or impermeability, have stronger ability to resist corrosion, which is beneficial to prolonging the life of the production Wells .
