Adsorbed on the surface of cement hydration particles, it inhibits the rate of cement hydration reaction, prolongs the thickening time, and stably regulates the waiting period of cement slurry under high temperature environment, without hindering the development of compressive strength in the later stage.\u003cbr\u003e \u003cbr\u003eCore selling point\u003cbr\u003e1. Stable high-temperature retarding effect, suitable for deep well high-temperature cementing conditions\u003cbr\u003e2. Controllable extension of thickening time to ensure the safety of injection replacement construction\u003cbr\u003e3. It has little impact on the rheological properties of cement slurry, and the later strength development is not inhibited\u003cbr\u003e4. Moderate sensitivity to dosage, easy to adjust formula\u003cbr\u003e5. Excellent compatibility, can be used in combination with various cementing additives\u003cbr\u003e6. Both dry mixing and slurry water feeding are available, with flexible construction\u003cbr\u003e \u003cbr\u003eProduct Advantages\u003cbr\u003e-Effectively delaying cement hydration, extending thickening time, meeting the requirements of cementing construction time for long sealing sections in deep wells, and preventing premature thickening during the construction process\u003cbr\u003e-Stable retarding effect under high temperature conditions, not easily ineffective, suitable for high-temperature well cementing formula\u003cbr\u003e-Small disturbance to the rheological properties of cement slurry, without damaging the overall performance of the slurry, and normal increase in compressive strength of cement stone after setting\u003cbr\u003e-Good compatibility with well cementing additives such as fluid loss agents, dispersants, and expansion agents, suitable for different density cement slurry systems\u003cbr\u003e-The feeding method is flexible, and it can be mixed with cement dry or added to the mixing water for use\u003cbr\u003e \u003cbr\u003eUsage\u003cbr\u003e1. It can be dry mixed with oil well cement or mixed with slurry water, and can be used in combination with other cementing additives.\u003cbr\u003e2. Add to the cementing formula for deep wells, high-temperature wells, and long sealing sections.\u003cbr\u003e3. Before on-site use, indoor formula trials must be conducted to determine the optimal dosage based on the circulating temperature at the bottom of the well, and then on-site construction can be carried out.\u003cbr\u003e4. Mix and stir thoroughly according to the formula ratio, and perform injection replacement cementing 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":50398025187685,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6073\/7381\/files\/31.jpg?v=1792117668","url":"https:\/\/wanxchem.com\/products\/oil-well-cement-retarder","provider":"wanxchem.com","version":"1.0","type":"link"}
