According to volcanic gas reservoir characteristics in the Jilin Oilfield, the effective protection measures are developed. A set of economical and adoptable low injury and solid-phase killing fluid system has been studied, and a reservoir of potential injury factors affordable is developed, density of which is continuously adjustable of 1.2-1.5g/cm3, temperature is up to 180°C. Treatment agents of the filtrate reducer, tackifiers, corrosion inhibitors used in formulations are all tare good biodegradability of environmentally friendly materials and the evaluation results show that the performance of the system is stable, flow ability and suppression are good, core permeability damage rate is low, damage degree to formation is small and by applying integrated completion technology, the operation process is simplified. Field application show that the set of technology can protect the original gas well production capacity better, reduce the damage to the reservoir putting into production with well completion, which is a technical system with great application value.

During the exploitation of oil field, sand production in oil and water wells is a very common phenomenon and it is essential technical measure to recover normal production and remove sand of oil and water wells. The conventional sand cleaning way not only can not achieve the requirement, quantities of sand washing fluid but also contaminates formation, resulting in oil well not to be normal production. A method of sand cleaning by negative pressure is studied on that is a simple operation, less workload, but also can solve problems of the formation loss, reducing water sensitivity, which is the development trend of sand cleaning process. ©, 2015, Well Testing.
