    "The successful development of this oil well has broadened the mindset of the mining process and has special significance
    .


    " Cheng Dongdong, deputy head of the Technical Supervision Station of Jianghan Oil Production Plant, Jianghan Oilfield, told reporters


    After years of development, Qian 43 oil group in the central area of ​​Wangchang Oilfield has entered a period of high water cut.
    Due to the complicated historical streamlines, it is difficult to accurately depict the remaining oil.
    At the same time, the well pattern is seriously damaged due to the impact of oil and water well damage, which restricts later adjustments.
    , Restricting stable production in old areas
    .

    The geotechnical staff of the plant adhere to the concept of benefit development, relying on the potential of the remaining oil in the potential tapping area, to study the distribution law of fine reservoir plane physical properties, carry out the analysis and fitting of historical streamlines and the description of the superior channel of the plane waterline, and summarize the plane remaining oil.
    Differential enrichment law, the work of fine reservoir description for Qian 43 oil group in the middle area was carried out
    .


    It is clear that the remaining oil in the weak streamline area is relatively enriched, and the overall deployment is carried out around the well-injected-production area, and the low-efficiency well Wangxixie 6-6 well sidetracking is optimized to tap the potential


    At the same time, since the buried 43 oil layer in Wangchang Middle Area is deep and the oil layer is relatively single, the use of low-cost sidetracking potential tapping mode can make full use of old wells to maximize benefits
    .


    In the past, sidetracking had high requirements for wellbore conditions, which restricted the efficient exploitation of remaining oil in the later stage of the reservoir.


    The technical supervision station of the plant organizes personnel to carry out the demonstration of the process design, combined with the drilling operation of the adjacent well, considering the possibility of lost circulation in the well, it is required that the on-site leak-proofing materials are sufficient before drilling
    .


    During construction, technicians go deep into the job site to monitor key links throughout the process


    In the next step, geotechnical personnel will closely follow the production situation, provide reference experience for tapping the potential of the remaining oil in the old area, and help the old area to increase production
    .
