摘要
水平井开发是油田上产增产的重要技术手段之一。虽然水平井的产量高,综合效益好,但因其井眼轨迹的特殊性,给固井施工带来了很大难度,增大了施工风险,使水平井的固井质量难以保证,直接影响了油水井的寿命。通过对影响水平井固井质量的因素分析,结合实例,探讨了确保水平井固井质量的有效措施和应用效果。指出,通过对固井质量的有效控制,能有效提高固井质量,使油井使用寿命延长。
Development of horizontal well is one of important technical means to increase the production in oilfields. Although horizontal wells have high output and better comprehensive benefit, they bring about some difficulties to cementing construction because of their own special features, which increase the risk of construction, make the cementing quality of horizontal wells hard to guarantee and affect the lifetime of oil well directly. Based on the analysis of factors affecting cementing quality of horizontal wells and some ex- amples, discussions focus on the effective measures and application effect of ensuring the cementing quality of horizontal wells. At last, it is pointed out that by the effective control of cementing quality the cementing quality can be improved and the service life of wells can be lengthened.
