This paper is the study of the gas communication andthe loss of hyd rostatic head of cement column caused by the gelling of cement slurry in the case of simulating the changes of temperature and pressuse in the well bore. From the results of experiments, it has been proved to be true that the gas communication and the loss of hydrostatic head of cement column caused by the gelling of cement slurry are serious, and the loss of hydrostatic head of cement column caused by the gelling of cement slurry can be calculated...

This paper is the study of the gas communication andthe loss of hyd rostatic head of cement column caused by the gelling of cement slurry in the case of simulating the changes of temperature and pressuse in the well bore. From the results of experiments, it has been proved to be true that the gas communication and the loss of hydrostatic head of cement column caused by the gelling of cement slurry are serious, and the loss of hydrostatic head of cement column caused by the gelling of cement slurry can be calculated quantatively after experimentation and mathematical analysis. This makes it possible that a sound basis is provided for taking technical measures to prevent oil, gas and water communication in the casing cementing job.

本文是在摸拟井身温度和压力变化的情况下,对水泥浆柱由于水泥胶凝引起的“失重”和气侵的研究。从实验研究的结果证实了水泥胶凝引起的“失重”和气侵是严重的,而水泥浆胶凝引起的“失重”,通过实验和数学分析后是可以作到定量计算的,这就可能给固井施工中,为防止油、气、水窜工艺技术措施,提供可靠的基本依据。

A kind of 51/2″ external casing packer has been proven very effective through both laboratory and field tests. The tool guards against ejection and blending outside the casing after well cementing job. The design feature, principle of operation, technical parameters and operation instructions are explained in this paper.

The eccentric of the main pump on CPT986 cementing trucks is made of steel-casting with high hardness and low impact toughness and accompanied with improper structural dimensions and interference fit, so it is susceptible to failures. The relevent improvement includes: having the eccentric made of 35CrMo steel forging, reducing the diameter of the processing holes, increasing the size of the critical sections, quenching and tempering to a lower hardness, and making the interference fit between shaft and...

The eccentric of the main pump on CPT986 cementing trucks is made of steel-casting with high hardness and low impact toughness and accompanied with improper structural dimensions and interference fit, so it is susceptible to failures. The relevent improvement includes: having the eccentric made of 35CrMo steel forging, reducing the diameter of the processing holes, increasing the size of the critical sections, quenching and tempering to a lower hardness, and making the interference fit between shaft and bore lighter. Nine pumps have been so improved and have carried out cementing jobs on more than 1,200 wells with 28 MPa maximum working pressure, pumping over 70,000 tons of cement in good working conditions.

CPT986水泥车大泵偏心轮为铸钢件,硬度高,抗冲击韧性低,加之结构尺寸和装配过盈量不合理,以致破裂时有发生。偏心轮的改进修复措施是选用35CrMo合金结构钢锻造,减小工艺孔直径,增大易破裂部位尺寸,采用调质处理,降低硬度,减小轴孔配合过盈量。经改进修复偏心轮的9台大泵,最高施工压力28MPa,固井1200余口,注水泥7万余吨,工作正常。
