103MPa-resistant high-strength fracturing propping agent and preparation method thereof
The invention relates to the technical field of oil and gas exploitation, in particular to a 103MPa-resistant high-strength fracturing propping agent and a preparation method thereof. The invention relates to a preparation method of a 103MPa-resistant high-strength fracturing propping agent, which comprises the following steps: uniformly mixing oil-based rock debris dry residues with quick lime, and carrying out high-temperature calcination pretreatment to obtain pretreated dry residues; crushing the pretreated dry residues to obtain dry residues; granulating the dry slag to obtain a blank ball; and sintering the blank balls to obtain the 103MPa-resistant high-strength fracturing propping agent. The 103MPa-resistant high-strength fracturing propping agent is also prepared according to the preparation method disclosed by the invention. According to the invention, resource utilization of the oil-based rock debris is realized, waste is turned into wealth, and the strength is higher; the particle size of the 103MPa-resistant high-strength fracturing propping agent is 40-70 meshes, the breakage rate under the closing pressure of 103MPa is smaller than 9%, the acid solubility is smaller than 7%, and the sphericity is larger than 0.9.
本发明涉及油气开采技术领域，具体涉及一种抗103MPa高强度压裂支撑剂及其制备方法。一种抗103MPa高强度压裂支撑剂的制备方法，包括以下步骤：将油基岩屑干渣与生石灰混合均匀，进行高温煅烧预处理，得到预处理干渣；将预处理干渣粉碎，得到干渣；将干渣进行造粒，得到坯球；将坯球进行烧结，得到抗103MPa高强度压裂支撑剂。本发明还根据前述制备方法制备获得了抗103MPa高强度压裂支撑剂。本发明实现了油基岩屑资源化利用，变废为宝，强度更高；本发明抗103MPa高强度压裂支撑剂的粒径为40～70目，在103MPa闭合压力下的破碎率＜9%，酸溶解度＜7%，圆球度＞0.9。
