Ceramsite proppant and preparation method thereof
The invention belongs to the field of petroleum and natural gas extraction, and relates to a ceramsite proppant and a preparation method thereof. The preparation method provided by the invention comprises the following steps: step 1, mixing oil sludge dry residues and pickling sludge, and then carrying out high-temperature pretreatment to obtain a mixture; 2, crushing the mixture obtained in the step 1, and granulating; 3, green pellets obtained after granulation in the step 2 are sintered, and a sintered body is obtained; and step 4, quenching the sintered body prepared in the step 3 to 60 DEG C or below to prepare the ceramsite proppant. The invention provides a preparation method of a ceramsite proppant, which is characterized in that oily sludge dry residue is used as a main raw material, acid pickling sludge is used as an auxiliary material, and the high-quality ceramsite fracturing proppant with the particle size of 70-140 meshes and the strength of 86 MPa is prepared; and the oily sludge dry residues and the pickling sludge belong to solid wastes, so that high-added-value utilization of the wastes is realized, chromium in the pickling sludge is prevented from being released into the environment, harmless use of the pickling sludge is realized, and the method is green and environment-friendly.
本发明属于石油、天然气开采领域，涉及一种陶粒支撑剂及其制备方法。本发明的制备方法包括以下步骤：步骤1、将油污泥干渣和酸洗污泥混合后高温预处理，获得混合物；步骤2、将步骤1获得的混合物粉碎后造粒；步骤3、将步骤2造粒后获得的生球颗粒进行烧结，得到烧结体；步骤4、将步骤3制得的烧结体骤冷至60℃以下，制得所述陶粒支撑剂。本发明提供了一种陶粒支撑剂的制备方法，所述方法利用油污泥干渣为主要原料，酸洗污泥为辅料，制得粒径70～140目、强度达到86MPa的高品质陶粒压裂支撑剂；且油污泥干渣、酸洗污泥都属于固体废弃物，实现了废物高附加值利用，避免酸洗污泥中的铬释放到环境中，实现酸洗污泥的无害化使用，绿色环保。
