随着油气田的勘探与开发的不断深入,高凝油藏、稠油油藏的勘探开发显得越来越重要,此种类型的油藏在勘探开发过程中,首先需要通过试油取得油层的产能、液性、地层参数等资料,由于原油具有高凝固点、高粘度特点,常规抽汲试油工艺不适用于该类油层试油,单纯采用地层测试方法又难以取得油层真实液性。

The technology of joint work of electric heat screw pump and formation tester is an advanced one for production test in heavy oil well or in well where oil is with high freezing point. It better solves the problems of production test and draining in the particular reservoirs. The draining of the screw pump can actually reflects the liquid property and productivity of the formation; special cable in the hollow rod can increase the fluid’s temperature, reduce its viscosity, and therefore enhance the mobility; the formation tester can be used for acquiring formation pressure, temperature and so on. Field application indicates that this technology is with better application future.
