Recent advances of modified polyacrylamide in drilling technology

The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

Synthesis and properties of poly(acrylamide-co-N

The prepared drilling fluid was tested on a room temperature medium pressure meter(7NS-2 A,Hengtaida,Qingdao). The test conditions were 100 psi at room temperature and a loss time of 30 minutes. The loss of filtration of drilling fluid under these conditions was tested, and the filter paper used was a special filter paper for drilling fluid.

In this work, the application potential of three kinds of cellulose nanomaterials (CNMs) with different aspect ratios and surface modified groups in water-based drilling fluids (WBMs) was studied. The surface modification groups and thermogravimetric analysis of CNMs were measured and compared. The effects of CNMs on the rheology and filtration of WBMs were investigated and compared with those
