Abstract

A green chelate production increasing agent and its preparation method and application, the raw material components of the production increasing agent include: 20-50 parts of glucose-δ-lactone, 1-10 parts of methylglycine diacetic acid, aspartic acid 10‑20 parts, 1‑5 parts of lactic acid, 2‑10 parts of lipopeptide, 0.1‑10 parts of enzyme, 1‑5 parts of VC, 1‑5 parts of potassium lactate, 0.1‑1 part of sugar, 1‑5 parts of ethanol , 20-62.8 parts of water are mixed and prepared, and are applied to the use of unblocking oil reservoirs and the cleaning of pipe columns; Biologically active chelating agent, which has both chelating and active functions, can effectively improve the efficiency of production increase. The product is designed with full consideration of the safety of transportation, storage and operation. Even if it is accidentally sprayed on human skin, it will not cause Great damage, the product material is derived from natural green additives, which has the excellent characteristics of safety, environmental protection and degradability.

Description

technical field [0001] The invention relates to a formula applied to an oil field production increasing agent, in particular to a green chelating production increasing agent and its preparation method and application. technical background [0002] With the continuous deepening of oilfield exploitation, the clogging of oil and water well formations is becoming more and more serious, resulting in a decline in oil well production. In order to increase oil production, a series of measures such as fracturing and acidification have been adopted. Due to the low cost of acidizing, hydrochloric acid-hydrofluoric acid and the addition of some corrosion inhibitors, surfactants and other components are used to remove scale in the wellbore and near the wellbore to improve permeability, which has become a popular method for increasing production and injection in oilfields. [0003] As we all know, the use of conventional industrial acids such as hydrochloric acid and hydrofluoric acid, w...
