Under the action of positive pressure difference, a dense shielding temporary blocking layer can be formed on the surface of the wellbore; Under reverse pressure conditions, the sealing layer can be unblocked, achieving the effect of protecting oil and gas reservoirs.\u003cbr\u003e \u003cbr\u003eCore selling point\u003cbr\u003e1. Unidirectional pressure differential temporary blockage, positive blockage, reverse can be released, protecting oil and gas reservoirs\u003cbr\u003e2. Adapt to porous and microfractured formations to effectively suppress the invasion of filtrate into the reservoir\u003cbr\u003e3. Optimize the density of the mud cake, reduce filtration loss, and assist in stabilizing the wellbore\u003cbr\u003e4. Do not damage the original rheological properties of the drilling fluid, and do not increase viscosity or shear\u003cbr\u003e5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents\u003cbr\u003e6. Controllable dosage, convenient construction, and reduced risk of reservoir damage\u003cbr\u003e \u003cbr\u003eProduct Advantages\u003cbr\u003e-The particle size distribution is reasonable, and a low-permeability shielding layer is quickly formed on the wellbore under positive pressure difference, blocking the invasion of drilling fluid filtrate and solid phase into the oil and gas reservoir. After perforation operation, the blockage can be resolved without affecting later production.\u003cbr\u003e-The outstanding sealing effect for leakage in porous sandstone and micro fractured formations reduces the complexity of underground leakage.\u003cbr\u003e-Improve the structure of the mud cake, make it dense and smooth, assist in reducing filtration, and stabilize the wellbore.\u003cbr\u003e-After addition, it has little effect on the viscosity and shear force of water-based drilling fluid, and does not disturb the original properties of the mud.\u003cbr\u003e-Good temperature resistance, suitable for most medium and deep well operating conditions, and easy on-site maintenance.\u003cbr\u003e \u003cbr\u003eUsage\u003cbr\u003e1. It can be used alone or in combination with other water-based drilling fluid treatment agents.\u003cbr\u003e2. Add the system in advance before encountering the oil and gas target layer during drilling; If there is a leaking formation, it can be supplemented in sections according to the leakage situation.\u003cbr\u003e3. It is recommended to refer to the working conditions for the recommended dosage on site. It is suggested to conduct indoor trials to determine the optimal dosage before on-site deployment.\u003cbr\u003e4. Normal circulation mixing and sufficient dispersion can be used for drilling operations.\u003cbr\u003e \u003cbr\u003eStorage precautions\u003cbr\u003eSealed and moisture-proof, avoiding exposure to sunlight and rain; Use up as soon as possible after opening; Wear dust-proof protective equipment during operation.\u003cbr\u003e\u003c\/p\u003e","brand":"Wanxiang","offers":[{"title":"Default Title","offer_id":50398025122149,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6073\/7381\/files\/29.jpg?v=1792117610","url":"https:\/\/wanxchem.com\/products\/single-pressure-sealer","provider":"wanxchem.com","version":"1.0","type":"link"}
