The exploitation efficiency of oil and gas resources depends on the cementing quality. In cementing engineering, interlayer migration occurs in the underground gas layer with cement hole as the main channel, which seriously threatens the sealing integrity of cement casing and leads to the failure of cementing operation. To improve the gas migration control ability of oil well cement (OWC), two carboxylated styrene‐butadiene latex nanomaterials styrene butadiene latex containing itaconic acid and sodium p‐styrene sulfonate (SBSI) and styrene‐butadiene latex containing methacrylic acid and sodium p‐styrene sulfonate (SBSM) were synthesized. The effects of SBSI and SBSM with different carboxyl structures on the gas migration control ability and pore structure of cement were investigated. The results show that the latex is densely packed on the cement matrix through the dissociation and adsorption behavior of carboxyl groups, and the smaller particle size and lower adsorption are more conducive to the formation of the film. The introduction of latex effectively shortened the transition time of cement gel state and significantly reduced the permeability of interlayer material migration. Compared with OWC, the transition time of cement containing SBSI and SBSM latex (SBSI/OWC and SBSM/OWC) decreased from 28 to 18 and 17 min, respectively, and the filter loss decreased from 60 to 40 and 36 mL, respectively. The isolation effect of the latex film on the interlayer gas and the provision of mechanical support have greatly improved the gas migration control ability of the cement and ensured the cementing quality. In addition, the refinement of cement pore structure caused by latex brings better rheological and mechanical properties to cement. This study clarified the change of latex in the gel transition stage of OWC from liquid to solid and revealed the mechanism of latex on the internal structure change of cement. It broadens the application range of latex nanomaterials in the field of OWC and provides a new possibility for the use of OWC in high temperature and high salt environment.

“…58 At high HA concentration, the number of available adsorption sites for Sb(V) decreases, and the complexation capability of HA for Sb(V) is lower compared to the adsorption capacity of FH. 59,60 Thus, we attribute this facilitated transport mainly to (1) enhanced truly dissolved Sb(V) transport fraction (Fig. S1 †), and (2) stronger repulsive force of colloidal systems.…”

“…When the material is synthesized by hydrothermal method under weak acid condition (left), the Ca-P 6 O 24 anionic coordination compound promotes the preferential growth of c-axis crystal and forms rodlike materials. Meanwhile, the RAPD could be transformed into cationic surfactant containing quaternary ammonium salt group (figure 9(b)), many positive charges generated on the surface of micelle can adsorb PO 4 3− , resulting in crystal heterotropism and formation of multi-level structure [51][52][53]. Due to the synergistic effect of low dielectric constant and high viscosity of self-assembled micelle template and ethanol, the rodlike clusters are formed by using micelles as templates [37].…”

Due to the combination of organic and inorganic advantages, organic@inorganic hybrid materials have important applications in drug-loading, water-treatment and other fields. Rosin@apatite (AP) hybrid materials with various morphologies were designed and obtained by in-situ reaction using two novel rosin-based phosphoester surfactants as organic phosphorus sources. The hybrid materials combined multi-ring, multi-electron groups of natural rosin diterpene and strong physical adsorption properties of apatite. Block and sheet rosin@AP hybrid materials were prepared by sol-gel method with mild reaction conditions. The materials have excellent adsorption capacity of phenol (9.2 mg/g) and loading capacity (492 mg/g) of adriamycin (DOX) induced by π–π stacking interaction with rosin bases. The content of rosin based organic materials in hybrid materials is as high as 47.5% by thermogravimetric analysis. The formation mechanism of hybrid materials was speculated in detail.
