Foamed cement paste and application thereof
The invention relates to the technical field of petroleum drilling, and discloses foamed cement paste and application thereof. The foamed cement paste is prepared from the following components in parts by weight: 100 parts of cement, 0.1 to 40 parts of toughening particles, 0.1 to 40 parts of an elastic agent, 1 to 30 parts of a fluid loss agent, 0.1 to 20 parts of a retarder, 1 to 30 parts of a filling agent, 0.1 to 20 parts of a foaming agent-I, 0.1 to 20 parts of a foaming agent-II, 0.1 to 20 parts of a foam stabilizer, 0.1 to 20 parts of a dispersing agent and 10 to 80 parts of water. The foam cement paste has the characteristics of wide density adjustment range, high compressive strength, short thickening time and wide temperature application range, can be applied to well cementation engineering of a slimming well of a shale gas well at the temperature lower than or equal to 95 DEG C, and has a good applicability effect.
本发明涉及石油钻井技术领域，公开了一种泡沫水泥浆及其应用，所述泡沫水泥浆包括以重量份计的以下组分：100份水泥、0.1‑40份增韧颗粒、0.1‑40份弹性剂、1‑30份降失水剂、0.1‑20份缓凝剂、1‑30份填充剂、0.1‑20份发泡剂‑I、0.1‑20份发泡剂‑II、0.1‑20份稳泡剂、0.1‑20份分散剂和10‑80份水。该泡沫水泥浆具有密度调整范围较宽、抗压强度高、稠化时间短、温度适用范围宽的特点，可在低于等于95℃条件下应用在页岩气井瘦身井固井工程中，具有良好适用性效果。
