近几年来,临盘油田的勘探开发逐步向深地层进行,钻探了几口深井,并获得了较好的油气发现,今后必将加大深部地层的勘探开发力度。而井越深,井下越复杂,固井完井的难度就越大。例如:随井深增加出现各种复杂的地层、井身结构复杂化、井身质量差、井底温度高压力大等很多问题,所有这些因素都影响到深井固井的施工安全,极大地影响到深井的固井质量。为此,通过开展深井完井固井工艺技术的研究和应用,以满足油田深层勘探开发的需要。
In recent years, the exploration and development of the Linpan Oilfield has been progressively carried out in the deep strata, drilling several deep wells and obtaining better hydrocarbon discoveries. In the future, it is bound to intensify the exploration and development of deep strata. The deeper the well, the more complex the well, the more difficult cementing completion. For example, many complicated formations, complex borehole structures, poor wellbore quality and large downhole temperature and pressure are all problems with the increase of well depth. All these factors affect the construction safety of deep well cementing and greatly affect Deep well cementing quality. Therefore, through the research and application of deep well completion cementing technology to meet the needs of deep exploration and development in the oil field.
