When encountering cement hydration products, expansive crystals are generated to compensate for the volume shrinkage during the solidification process of cement slurry, and to improve the bonding quality between the cement sheath, casing, and formation.\u003cbr\u003e \u003cbr\u003eCore selling point\u003cbr\u003e1. Effectively compensate for the solidification shrinkage of cement stone, eliminate micro gaps and micro ring gaps\u003cbr\u003e2. Improve the bonding strength between the first and second interfaces and enhance the interlayer sealing ability\u003cbr\u003e3. Has little impact on the rheological properties and thickening time of cement slurry\u003cbr\u003e4. Good temperature resistance, suitable for multi-stage cementing conditions\u003cbr\u003e5. Excellent compatibility, can be used in combination with various cementing additives\u003cbr\u003e6. Stable dosage and simple construction operation\u003cbr\u003e \u003cbr\u003eProduct Advantages\u003cbr\u003e-Hydration produces moderate volume expansion, offsetting cement solidification shrinkage, reducing micro cracks and micro voids, and preventing oil, gas, and water from flowing through\u003cbr\u003e-Improve the bonding quality between cement casing and cement formation, and enhance the interlayer sealing effect\u003cbr\u003e-Reasonably regulate the expansion rate without interfering with the thickening time and compressive strength development of cement slurry\u003cbr\u003e-Good compatibility with well cementing additives such as fluid loss agents, retarders, dispersants, etc., suitable for different densities of cement slurries\u003cbr\u003e-Good flowability of powder, uniform mixing, suitable for on-site processes such as ground mixing and dry mixing feeding\u003cbr\u003e \u003cbr\u003eUsage\u003cbr\u003e1. It can be dry mixed with cement or mixed with slurry water for use, and can be used in combination with other cementing additives.\u003cbr\u003e2. Determine the addition ratio based on well temperature, cement formula, and working conditions.\u003cbr\u003e3. Before on-site use, it is recommended to conduct indoor formula trials to determine the optimal dosage before on-site construction.\u003cbr\u003e4. Complete the mixing and stirring according to the cementing process, and carry out the replacement cementing operation normally.\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":50398025285989,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6073\/7381\/files\/35.jpg?v=1792117746","url":"https:\/\/wanxchem.com\/products\/expansion-agent-for-cementing","provider":"wanxchem.com","version":"1.0","type":"link"}
