This solution introduces the well - cleaning operations for optimizing wellbore storage and circulation environment. With the increase of deep well and ultra deep well developing, drilling is becoming more and more difficult, and oil companies are more and more sensitive to the input-output ratio. Problems during drilling and oil recovery. Expandable well technology solves the above problems and becomes one of the core technologies of the oil drilling industry in the 21st century. This solution Introduces the Expandable Tubular Technology, involving Expandable casing and Expandable screem.

The conceptual scheme is mainly aimed at T oilfield polymer flooding test area at South America. In early stage, most wells had response, and the overall fluid and oil production in pilot area increased. In mid-to-late stage2C multiple wells had a sharp rise in polymer concentration and glide in oil production.The results of pilot test differ from prediction. The water cut almost reached 90 until 2014 After a comprehensive analysis of information, find out the question crux. According to different conditions, puts forward some countermeasures to improve the effect of polymer injection and the follow-up research work.

This solution mainly introduces common troubles of standard conventional wellhead, Maintenance and parts solutions, Remove and repair tools and Field testing tools.The most commonly used valves in wellhead equipment include plate gate valves, choke valves, safety valves and ball valves. Due to the abrasion, vibration and corrosion caused by the media, the aging deformation and improper operation of the sealing parts, the valve can leak easily.

Sand control in powder sandstone, argillaceous fine sand rock oil well and gas well development has always been a difficult problem In the case of fine sand, the sand filter pipe will be seriously blocked, and the production capacity will decrease rapidly after being put into operation The problem of gas well is more prominent, due to the blockage of the sand filter pipe, the production capacity is reduced rapidly on the one hand; on the other hand, the other blockage of the other side causes partial concentration of the gas pressure, and the sand-filtering pipe blow-through will cause the sand-proof failure, which is a serious problem that is common and difficult to solve The problems mentioned above can be solved effectively by shaft block-free chemical sand-fixing technology.
