This paper introduces the research results of techniques of testing PC pump oil well through one-year efforts. Which covers the mathematical models of a number of force characteristics strength analysis, and resonance critical problems of rotation rod-string in PC pump wells: resulting of testing method of polish-rod load and rotation rate on the basis of feasible demonstration and technical requirement analysis; study and manufacture of system of testing PC pump well, which involves sensor, collector ring, acquisition circuit and computer; research and determination of assistant technology of testing force on rotation polish-rod and formulation of testing force on polish-rod. A spot testing has been carried out by means of the above research fruit and good results have been achieved.The success testing results in has laid a strong foundation for the oil well diagnosis.

It can be seen from the long time asymptotic solutions, that the pressure curve is a concave curve and ...

注稠化水等措施是改造这种油层的方向，但最终界限目前还不好确定。浊层研究、油田开发和各种油井工程措施应当考虑相对流动比这一因素。

And it isconcluded that electric heating oil production should be applied in low water bearing wells,the liquid supply ability of high condensation point and high waxy oil wells can be less than 40m 3/d,and the liquid supply ability of viscous crude oil wells should be more than that.

通过对各类井筒温度分布曲线的综合分析得出：在电加热工艺选井方面，对高凝、高含蜡油井，应选择液量在 4 0 m3/ d以下且含水较低的井；而对于稠油井应选择供液能力较好且含水较低的井。

The theory is applied to Tahe oilfield and an oil well tested twice is interpreted by it. The case study indicates that the theory has a good practicability and a consistency with field conditions.

将该理论在塔河油田进行了实际应用，并对一口进行过两次测试的油井的渗透率变化进行了计算，计算结果表明，该理论实用性较强，和油田实际符合较好。

In drilling an oil well, mud is used to lubricate the cutting bit.
