Results of the use and ways to improve transcolumn packers at fields of the Tatar ASSR

Journal Article:

Abstract

A classification is made of wells according to the complexity of separation of the beds. Five categories are isolated. The criterion for comparing the categories was the presence or absence in the productive part of the section of water-bearing levels and screening beds. In a number of cases, as a result of unsatisfactory sedimentation stability of the cementing fluid, channels can be formed in it which may be the reason for transcolumn overflows and interruption in the removal of pure (not containing water) oil. In order to control transcolumn overflows in wells of the II-III-IV category, packer-filters (PFM) are used whose action is based on the forced recovery from the cement fluid of part of the liquid phase. The use of PFM is recommended only after conducting of a set of special (laboratory, geophysical, geological-technical, ect.) studies. The possibility is shown of positive use of PFM not only in the well shafts of nominal diameter, but also in wells prone to cavern formation. In the example of well No 13993 of the Abdrakhmanovskiy field, the possibility is shown of sectioning the PFM. Based on the PFM, and PFU was created with elongated filtering part. The results of introducing the PFU  More>>

The results of introducing the PFU and the PFM are positive, and the economic effect from using the PFU is 1.5-fold greater than from PFM. In addition to PFU and PFM, the wells of the association ''Tatneft''' have used packers of the type PPG designed by the All-Union Scientific Research of Drilling Equipment. The results of introducing the packers PPG are positive.}
