Dual-Layer Reservoir Sealing Reagent

Shengli Oilfield Kaidu Petroleum Technology Development Co., Ltd. 3T Comprehensive Drilling Performance Improver is multi-functional Drilling Fluid Additive. It can be directly mixed into all kinds of drilling fluids to establish 3T drilling technology, and matched with our full chemical series including Heavy Oil Viscosity Reducer, Demulsifier & Water Purifier, Scale & Corrosion Inhibitor, H2S Scavenger and Shale Inhibitor, covering drilling, reservoir protection, heavy oil exploitation and surface produced water treatment.   This fibrous solid particle forms high-strength shielding film in formation pores via bridging inert materials and cementing active minerals, raising formation fracture pressure above 40 MPa. Meanwhile, hydrophobic interfacial film is generated to prevent water invasion and water blocking. A dense double-layer impermeable protective membrane is built, suitable for formations of variable permeability and fractured shale to realize non-permeable drilling. I…
