Study On Carboxylic Styrene Butadiene Latex Complex Cement Slurry System

Nowdays many domestic oil fields turn into metaphase or anaphase exploitation, exploitation degree broaden continuously,the downhole behaviour furthermore complex, some problems affect intensity of cementation and quality of isolation of individual zones need to be resolved.The performance of common oil well cement stand up todamage is bad, so it can't meet the demand from the impact resistance vibration, perforation and fracture. All these problems place restrictions on the development of the small hole well, extended reach well, controlled directional well and horizontal well, these also condition the implementation of fracture and acidation. Inland study on the cement slurry that have multiple performances and is fit for bad hole well cementation is little.The slurry that have multiple performances such as liquid state performance, preventing oil/gas/water channeling, the high quality of isolationof individual zones and the endurance quality of cement is lack. The carboxylic styrene butadiene latex (XSBR) was synthesized in the laboratory.Then, excellent to elect related treatment pharmaceutical, fibre material (XW) and expanding agent material (BS500).The carboxylic styrene butadiene latex complex cement slurry system have been given based on laboratory testing and its normal properties. The result of study indicated,The slurry is low to fluid loss and zero free liquid, the thickening curve emerged right angle with short transition period and microdilatancy,also resistance to corrosion. As oil/gas/water channeling is prevented, have an excellent rheological behavior;the outer pressure resistance is high,the quality of isolation of individual zones is developed, it is excellent in quality to cement the well.
