Special Issue Information

Dear Colleagues,

Cementing is the technology of running casing in a well and injecting cement slurry into the annulus between casing and formation. The quality of cementing is very important to the life,and efficient production of a well. Cementing materials and cementing technology are the key to ensure cementing safety and cementing quality. Deep sea, deep earth, polar, shale gas, shale oil and other oil and gas wells, geothermal wells, coal gasification wells and CCUS wells have brought great challenges to cementing, and new cementing materials and technologies are urgently needed to meet these challenges. Submissions are welcome in the form of original research papers or reviews that reflect the state-of-the-art of this research area.

An effective drilling fluid removal is necessary to achieve an efficient cementing in oil and gas industry, i.e., it is ideal that all the drilling fluid is displaced by the cement slurry. The displacement efficiency is closely related to the stability and development of the displacing interface between the cementing slurry and drilling fluid. Thus, an effective cementing requires a validated theoretical model to describe the displacing interface to guide cementing applications, especially for highly deviated wells. The current studies suffer from a lack of experimental validation for proposed models. In this study, a theoretical model of cementing interfacial displacement in eccentric annulus is established. An experimental study is conducted to examine effects of well inclination, eccentricity and fluid properties on the stability of displacement interface to verify the theoretical model. The model is found to well describe the interface in the eccentric annulus, and it is applicable to the wellbore annulus with different inclination angles. The results show that: the displacement interface gradually extends (i.e., length is increased) with the increase of well inclination; the cement displacement effect became worse with deviation angle under the same injection and replacement conditions. Increasing the apparent viscosity of cement slurry is beneficial to improve the stability of displacement interface. In highly deviated wells, a certain casing eccentricity can inhibit the penetration of cement slurry in the wide gap of the low side of the annulus, which is conducive to maintaining the stability of the displacement interface.

Carbon dioxide capture and storage is the primary way to reduce greenhouse gas emissions on a large scale. Carbon dioxide storage is the critical link of this technology, and the way in which to achieve long-term storage is a problem to be considered. The elastic and anti-corrosion cement slurry is the key for the successful storage of carbon dioxide. In order to develop the cement slurry for carbon dioxide storage, the influence of resin with both elastic and anti-corrosion properties on the performance of a cement slurry was investigated. The dispersant, retarder, and filtrate reducer suitable for the cement slurry were studied, and the performance of the designed cement slurry for carbon dioxide storage was evaluated. The experimental results show that the resin can reduce water loss and improve the elasticity and corrosion resistance of cement paste. The elastic modulus and corrosion depth of the resin cement slurry were significantly lower than those of the non-resin cement slurry. By studying the dispersant and retarder, the performances of the cement slurry for carbon dioxide storage was found to be able to meet the requirements of the cementing operation. The water loss of the designed cement slurry was low, the thickening time was more than three hours, and the rheological property was excellent. The elastic modulus and corrosion depth of the designed cement slurry was very low. The cement paste had a strong resistance to damage and corrosion. The structure after corrosion was denser than the conventional cement slurry, and the characteristic peak of corrosion products was weaker. The designed elastic and anti-corrosion cement slurry was well suitable for the cementing operation of carbon dioxide storage wells. Full article

Oil well cement microcracks cause formation fluid channeling, compromising oil and gas extraction safety. Superabsorbent polymer (SAP) can absorb water and swell to prevent fluid channeling. In this study, an alkali-resistant and pH-sensitive SAP was prepared based on the properties of oil well cement slurry. The preparation of the SAP was optimized, including monomer ratio, cross-linking agent dosage, and monomer concentration. The pH sensitivity and alkali resistance of the SAP were evaluated. The results revealed that the SAP exhibited good pH sensitivity, with the absorption rate in water being 2.18 times that of cement slurry filtrate (CSF) at 95 °C. Furthermore, the FTIR spectrum showed that the SAP had a stable molecular structure. The secondary absorption rate in water of the SAP after soaking in CSF was not different from the original absorption rate. Styrene–butadiene latex (SBL) can be used to adjust the SAP’s absorption rate. The SAP’s absorption rate had a good exponential functional relationship with SBL dosage. The SBL dosage can be determined by the functional relationships to prepare a SAP with the required properties. Full article
