Abstract

The invention discloses a formation temperature testing method and device. The formation temperature testing method comprises the following steps that drifting is carried out by using a gauge cutter,and the gauge cutter is lowered to a preset depth; a tester is lowered into a wellbore, wherein the tester is provided with a plurality of test points on the same cross section, the test points are uniformly arranged in the circumferential direction of the wellbore, and the test points are in contact with the inner wall of a casing in the wellbore; the tester is lifted, and in the process of lifting the tester, a fixed-point test is carried out at a predetermined interval distance; and temperature data of the test points in the tester are acquired, and the formation temperature is determined according to the temperature data. The formation temperature testing method and device can accurately obtain the formation temperature, so that better guidance is provided for field operation.

Description

technical field [0001] The invention relates to the technical field of heavy oil production, in particular to a formation temperature testing method and device. Background technique [0002] At present, many domestic heavy oil fields are undergoing steam huff and puff recovery and steam flooding production. Among them, the real (or static) formation temperature is an important parameter for exploration, drilling, logging, completion and oil production engineering, and also an important parameter for evaluating the formation. Generally speaking, the downhole temperature increases with the depth of the well, and the rate is called the geothermal gradient. [0003] Especially in the following situation: Since the pressure, temperature and physical properties of the reservoir in the old block of the heavy oil field will change greatly with the long-term exploitation, if the previous data are continued to be used, it will inevitably affect the formulation of the development plan...
