Study And Application Of Grey-Mortar Treatment Technology In Menggulin Oilfield

With the continuous development of Menggulin oilfield,the mortar well increasing,not only the costs of production increase,directly affect the production of oil well production and oil field,and the production stop due to the mortar injection Wells creates underground injection-production balance,serious impact on the ultimate recovery factor of oilfield.Based on Menggulin oilfield as the research object,this paper through the analysis of its geological structure,reservoir characteristics,fluid characteristics,and the mechanism of sand(mortar),in turn,introduces the oilfield using three types of mechanical sand control technology and prepare for trial three chemical sand control technology.On the one hand,the site selection well number construction,obtain the first-hand admission data;On the one hand,in the laboratory,respectively for the effectiveness of the curing agent,curing agent formula related experiment of optimization experiment,filling medium optimization experiment,fiber of various parameters on the stability of sand body series experiment,fiber performance study of sand body.According to the experimental results,formulate reasonable sand control scheme,the selection of the targeted technical types: double cementation sand process and high elastic rubber process management,to shut down the single well as the main object of governance,and for the construction.By observation of governance and a year of recovery,to shut down the well to resume production,and keep the reasonable oil and gas production,played a good role,to slow the oil and water Wells mortar,prolong production time,the purpose of but for the normal production of the mortar well effect is not obvious,such as the ultimate form suitable for Menggulin oilfield management technology provides a valuable experience.
