DEVELOPMENT OF AN EFFECTIVE TECHNOLOGY FOR DEEP PURIFICATION OF WATER FROM SUSPENDED SOLIDS TO MAINTAIN RESERVOIR PRESSURE

Using for example Uzen oil and gas field, this article explores the peculiarities of oil production at fields located at the middle and late stages of development. Particular attention is paid to the need to pump water into the reservoir to maintain reservoir pressure. The main methods of purification of oilfield wastewater are considered. The Uzen field was analyzed in detail, the requirements for water quality to maintain reservoir pressure, as well as presented results of monitoring of solids and oil products in the injected water of the Uzen field. According to the injected reservoir water data at the Uzen field, we have built a projection model that takes into account the content of mechanical additions. The tests made in the reservoir of wastewater pumped at Uzen formation proposed experimental setup for water purification to maintain reservoir pressure. Experiments on water purification showed significant results
