Sinopec News Network News Recently, Shengli Oilfield Petroleum Engineering Technology Research Institute Oil Protection Institute implemented a new acidification process at Dongxin Oil Production Plant and saw good results
.
The fluid production and oil output of the three wells have not only been greatly improved, but also a large amount of operating costs have been saved because of the immobilization of the pipe string, which has been well received by the site
The three wells X17C8, Y72-338, and X11-x213 in the Xinyi management area of Dongxin Oil Production Plant are located at the edge of the fault block.
The oil layers are poorly developed and the formation energy is insufficient.
Later, due to formation pollution blockage, no fluid can be discharged
.
After receiving the task, the technicians of the Oil Protection Institute fully analyzed the data, carefully prepared the well fluid formula, and designed to reduce the amount of well fluid to protect the reservoir and downhole tubing string, using protection slugs + low-damage retarding acid.
The advantages of the new acidification process are obvious: one is that the amount is small, which not only reduces the cost of the measure, but also reduces the pollution damage of the well fluid to the formation; the second is that the configured acid solution has little damage to the downhole tubing string, which greatly extends the life of the tubing string; Because the pipe string is not moved, a lot of operating costs are saved, and the field promotion and application prospects are broad
