Shengli Oilfield's deep plugging adjustment site realizes automatic injection

Recently, the deep plugging and adjustment automatic injection equipment jointly developed by the Shengli Petroleum Engineering Technology Research Institute Ground Center and the Third Mining Institute was successfully put into operation at the Gudong plugging and adjustment site, providing the expected effect of water plugging and profile control.

Water plugging and profile control technology has been widely used in Shengli Oilfield, with an annual workload of more than 200 wells and an average single well oil increase of more than 600 tons.
It has become the leading technology for water control and oil stabilization in high water-cut oilfields
.
As the integrated oilfield enters the ultra-high water cut period, the water plugging and profile control technology has also entered the deep plugging and control stage

Compared with traditional plugging and regulating, the deep plugging and regulating injection system is more complicated, and the range of plugging agent concentration and displacement is wide, which puts forward higher requirements on injection equipment
.
The existing plugging agent injection equipment has many problems: open operation, dusty dust, poor working environment; multi-person rotation operation, labor intensity; all kinds of agent dosing are done manually, human influence factors are large, and liquid concentration and quality are difficult.

Aiming at the contradiction that the existing plugging agent injection equipment cannot meet the injection requirements of deep plugging and adjusting mines, Shengli Engineering Institute has carried out the development of automatic deep plugging and adjusting automatic injection equipment, focusing on "automatic and reliable feeding, rapid viscosity retention and maturation, and long-life high-efficiency pump injection".
The goal is to develop and form a skid-mounted deep plugging and adjusting automatic injection equipment
.
The equipment has the following technical characteristics: it realizes automatic feeding, which solves the problem of high labor intensity; prevents solid phase agglomeration and solves the problem of uneven liquid distribution; pays attention to viscosity maintenance and solves the problem of low injection efficiency

Since it was put into operation on August 27, the on-site operation of the automatic injection equipment for deep plugging and adjustment has been stable.
It has realized the automatic feeding and preparation of two types of solid particles and liquids.
It can automatically and rotate the dosing pool according to the set displacement requirements.
Water supply, liquid preparation, maturation and injection
.

As the preparation and injection process is fully automated, the influence of human factors is greatly reduced, and the quality of the liquid preparation construction is ensured
.
At the same time, the labor intensity is greatly reduced, and the on-site personnel on duty is reduced from at least 2 people on duty to only 1 person on duty to complete the automatic operation; the feeding time is changed from once every 2.

The successful trial operation of the deep plugging and adjusting automatic injection equipment greatly improved the on-site liquid distribution and injection quality, and ensured that the on-site construction was implemented in strict accordance with the plan design, with low cost and labor intensity, and had a good prospect for industrialization
