The utility model discloses a kind of separation and purification system of secondary steam in MVR evaporation system, including cylinder, cylinder is sequentially distributed with cyclone separation chamber, purification settling chamber and silk screen demisting chamber from bottom to top, cyclone separation chamber middle part has spray washing chamber, spray washing chamber bottom is connected with cyclone separation chamber, spray washing chamber top is connected with purification settling chamber, cyclone separation chamber is connected with steam inlet pipe, silk screen demisting chamber is connected with steam outlet pipe, cyclone separation chamber has collection tank, collection tank is used to collect the droplet of secondary steam being thrown to cylinder wall, spray washing chamber has spray pipe, spray pipe is used to spray atomized washing liquid contact secondary steam absorption volatile component contained;By cyclone separation, countercurrent spray washing, sedimentation and silk screen demisting four-stage treatment process, liquid droplet, mist droplet and volatile component in secondary steam are purified gradually, greatly improve the purification quality of secondary steam, effectively solve the problem of poor effect of traditional purification mode.

This invention relates to a method for identifying tight sandstone gas reservoirs, belonging to the field of oil and gas reservoir exploration and development technology. The method, based on original drilling data (field logging data and gas testing data), calculates the tight gas content index through parameter reconstruction. This index, geologically significant as a characterizing index of reservoir gas content, then establishes a correspondence between fluid properties in the study area and the tight gas content index and average sonic transit time. Finally, the fluid properties of the target layer are determined based on the tight gas content index and average sonic transit time. This method provides effective guidance for oil and gas exploration, evaluation, and development, improving the efficiency of drilling oil, gas, and water layer identification, reducing identification difficulty, and offering advantages such as simple operation, straightforward calculation, no need for highly skilled field personnel, high interpretation accuracy, and low processing time.
