During the drilling and development of sour natural gas (including CO 2 H S) fields, due to high solubility in fluid, concealment after invasion increases, resulting well control accidents. Therefore, it is great significance for field deeply study understand acid flow law annular air liquid invasion. In this paper, a multiphase equation considering dissolution established. Based on existing ex...

In order to solve the corrosion problem of production string in process acidizing for purpose production, a new water-based annular protective fluid suitable HTHP acid gas, including H2S-CO2 wells, was developed. Firstly, an appropriate deoxidizer, bactericide, and inhibitor shall be selected according gas. addition, synergism between additives is evaluated. Then, by designing additive ratio, o...

CHO cells transfected with high-affinity 5HT receptors were used to detect and identify the release of serotonin from taste buds. Taste cells release 5HT when depolarized or when stimulated with bitter, sweet, or sour tastants. Sour- and depolarization-evoked release of 5HT from taste buds is triggered by Ca2+ influx from the extracellular fluid. In contrast, bitter- and sweet-evoked release of...

A rural population in southwestern Alberta, Canada, living downwind from natural gas refineries, has expressed concerns about an excess of adverse health outcomes over the last 25 years. This has escalated to the point of causing a prominent sociopolitical controversy within the province. As part of a large field epidemiologic study undertaken during the summer of 1985 to investigate possible h...

Chemotherapy-induced taste disorder is one of the critical issues in cancer therapy. Bortezomib, a proteasome inhibitor, is a key agent in multiple myeloma therapy, but it induces a taste disorder. In this study, we investigated the characteristics of bortezomib-induced taste disorder and the underlying mechanism in mice. Among the five basic tastes, the sour taste sensitivity of mice was signi...
