High-temperature-resistant tackifier for well cementation engineering and preparation method thereof
The invention discloses a high-temperature-resistant tackifier for well cementation engineering. The high-temperature-resistant tackifier is prepared from the following components in parts by weight: 100 parts of attapulgite, 10 to 400 parts of bentonite, 10 to 400 parts of sepiolite, 10 to 400 parts of diatomite, 5 to 30 parts of dispersing agent, 5 to 15 parts of fiber and 5 to 20 parts of auxiliary agent. The attapulgite and other inorganic materials are used as main components, the use amount of the attapulgite and other inorganic materials can account for 89% or above of the total mass of the raw materials, the problems of molecular chain breakage, degradation and the like of the organic tackifier under the high-temperature condition are effectively solved, and better low-temperature performance and construction performance can be considered; and the related preparation process is simple, the cost is lower, and the oil well cementing agent can be widely applied to oil well cementing engineering and has higher economic and popularization values.
本发明公开了一种固井工程用抗高温增粘剂，各组分及其所占重量份数包括：凹凸棒土100份，膨润土10‑400份，海泡石10‑400份，硅藻土10‑400份，分散剂5‑30份，纤维5‑15份，助剂5‑20份。本发明以凹凸棒土等无机材料为主要成分，其用量可占原料总质量的89％以上，有效克服有机增粘剂在高温条件下的分子链断裂和降解等问题，可兼顾较优的低温性能和施工性能；且涉及的制备工艺简单、成本较低，可广泛应用于油井固井工程当中，具有较大的经济和推广价值。
