Abstract

The invention relates to a foam stabilizer composition, foam cement slurry additive and foam cement slurry. The foam stabilizer composition is mainly composed of the following components by weight: 100 parts of C12-C22 alkylamidopropyl betaine, 100-150 parts of animal keratin protein hydrolyzate, 75 parts of C8-C14 sodium alkylbenzenesulfonate 120 parts, C6-C20 alkylamide alkylamine oxide 60-100 parts; the animal keratin hydrolyzate is obtained by hydrolyzing animal hoof horn powder, and the mass concentration is 25-40%. On the basis of ensuring the stability of the foam, the foam stabilizer composition can achieve uniform adhesion on the foam liquid film, thereby making the foam in the foam cement slurry system fine and uniform, reducing the pore structure defects of the foam cement stone, which is beneficial to Improve the permeability and compressive strength of foam cement stone at lower density.

Description

technical field [0001] The invention belongs to the field of cement slurry for well cementing, and in particular relates to a foam stabilizer composition, a foam cement slurry additive and a foam cement slurry. Background technique [0002] In the process of oil and gas exploration and development, it is often faced with low-pressure and leaky formations. When performing cementing operations in low-pressure, leaky formations, we often face the problems of cement slurry leakage and insufficient return height. In order to prevent cementing leakage, foam low-density cement slurry is often used for cementing to ensure the return of cement slurry and cementing quality. [0003] Foamed cement slurry is a low-density three-phase viscous fluid prepared by filling the cement slurry with gas and using surfactant substances to improve foam stability. It has low density, low permeability, low water loss, low Thermal conductivity, compressibility, high mud displacement efficiency, good...
