Acidified fracturing fluid continuous mixing and preparation device

Abstract

The invention relates to an acidified fracturing fluid continuous mixing and preparation device, and belongs to the technical field of oil and gas field equipment. Under the cooperated control of a PLC system, dry powder automatic unpacking, feeding and metering devices are integrated into a potassium chloride and guar gum metering feeding unit; the automatic feeding and precise metering of potassium chloride and guar gum are realized; in addition, the metered powder material and the pumped clean water are respectively and sufficiently mixed in a potassium chloride water-powder mixing tank anda guar gum water-powder mixing tank; the mixture enters the inner wall of the mixing tank from a feeding opening along the tangent line; then, according to the liquid proportion, the acid liquid andvarious chemical additives are respectively pumped into the mixing tank along the tangent line; through stirring, the liquid is downwards pushed; a rotational flow in the horizontal direction is formed in the tank; the proportional addition of various substances is realized; the output discharging capacity and the preparation quality of the fracturing liquid are ensured. The continuous mixing andpreparation device provided by the invention has the advantages that the structure is compact; the occupied field is small; the automation degree is high; the operation is convenient; the fracturing construction efficiency can be obviously improved.

Description

technical field [0001] The invention relates to an acidizing fracturing fluid continuous mixing device, which belongs to the technical field of oil and gas field equipment. Background technique [0002] In order to maximize the permeability of oil and gas well reservoirs, thereby increasing the recovery factor of oil and gas wells, and finally increasing the production of oil and gas wells, acid fracturing has become one of the essential measures for increasing and stabilizing production in oil and gas fields at home and abroad. Continuous fluid preparation and supply of fracturing fluid are two important links in fracturing field construction. Field construction results over the years have proved that the traditional method of liquid preparation and supply is not only slow, but also has uncertain factors, such as sand Blocking etc. will also produce huge waste. In order to seek faster and better development in the future, the fracturing industry must develop a variety of e...
