fluid loss additive for cement

Dec 12 2017 · A basic 158 ppg cement slurry with no chemicals to improve fluid loss will usually have a fluid loss value higher than 1500 ml30 min ref Well Cementing Nelson Guillot How do you control fluid loss All service companies providing cementing service on rigs use several chemicals to improve fluid loss control

Our objective in the research described here was to use new monomers to synthesize a novel fluid loss additive In order to ensure that it has a superior performance to control the fluid loss of the oil cement slurry the macromolecular polymers should have rigid radical strong absorption groups to the oil cement particles and superior thickening properties 6 7

offers 1239 cement fluid loss additive products About 28 of these are Petroleum Additives 0 are Electronics Chemicals and 0 are Paper Chemicals A wide variety of cement fluid loss additive options are available to you such as classification usage and type

In most cements additive concentrations of 1 or less provide adequate fluidloss control However additive concentrations can be varied for individual well requirements Halad9 additive is available as a freeflowing powder that can be added to dry cement or as a liquid that can be added to the mixing water

Fluid Loss Control Additives As cement is pumped across a permeable rock surface under pressure cement filtrate or water is lost or squeezed out of the cement into the rock Cement fluid loss must be controlled to obtain the right rheological properties for placing the cement and to ensure a good cement bond to pipe and formation

Fluid loss control additives are employed for maintaining a constant watersolid ratio in cement slurries downhole by controlling the rate of water loss to adjacent permeable zones through suitable viscosification otherwise the cement slurries would lose water by filtration into these zones This filter loss may be static or dynamic

KELIOIL is headquartered in Tianjin hightech industrial park and its manufacturing base is located in Ninghe district with an area of 30000㎡ over one third of which are workshop and warehouse As a global supplier of oilfield cementing additives 60 of its products are exported to many countries and regions around the world

A fluid loss additive is described 57 that helps to achieve a desired fracture geometry by lowering the spurt loss and leakoff rate of the fracturing fluid into the surrounding formation by rapidly forming a filter cake with low permeability The fluid loss additive is readily degraded after the completion of the fracturing process

Dispersants and fluid loss additives for inclusion in oil field cements and methods of using the resultant compositions in oil gas and water well cementing operations are disclosed Such compositions incorporate a polymeric additive prepared by causticcatalyzed condensation for formaldehyde with acetone or a substance derived from acetone wherein said polymer includes sodium sulfonate
