Abstract

Изобретение относится к нефтедобывающей промышленности, в частности к гидродинамическим способам повышения нефтеотдачи пласта. Задачей изобретения является увеличение нефтеотдачи морских нефтяных месторождений при заводнении пластов морской водой с применением химических реагентов для снижения межфазного поверхностного натяжения на границе вода - нефть и создания структурного расклинивающего давления на трехфазной границе. Поставленная задача решается тем, что в способе разработки морских нефтяных месторождений заводнением, включающем введение в морскую воду соли натрия с последующей закачкой ее в залежь, после введения в морскую воду соли натрия ее смешивают с кислотой и добавляют стабилизатор, при этом в качестве соли натрия используют карбонат натрия, в качестве кислоты используют (2-бис-(карбоксиметил)амино)пентановую или азотную кислоту, а в качестве стабилизатора - ПЭГ8000 в соотношении, мас.%: карбонат натрия - 9, кислота - 10, ПЭГ8000 - 0,5 и морская вода - остальное.The invention relates to the oil industry, in particular to hydrodynamic methods for enhancing oil recovery. The objective of the invention is to increase the oil recovery of offshore oil fields during seawater flooding with the use of chemicals to reduce the interfacial surface tension at the water-oil interface and create a structural wedging pressure at the three-phase boundary. The problem is solved by the fact that in the method of developing offshore oil fields by flooding, including the introduction of sodium salt into seawater followed by its injection into the reservoir, after the introduction of sodium salt into the seawater, it is mixed with an acid and a stabilizer is added, while sodium salt is used sodium carbonate, (2-bis- (carboxymethyl) amino) pentanoic or nitric acid is used as an acid, and PEG8000 is used as a stabilizer in a ratio, wt%: sodium carbonate - 9, acid - 10, PEG8000 - 0.5 and sea water is the rest.
