Detailed description of the invention
As shown in Figure 1, high-temperature thermal production well downhole testing method, which comprises at least: sensor 3, measuring circuit 4, there are the layer of measurement position 1 and slough 2 in down-hole 6, layer position 1, in the bottom of down-hole 6, measured in well in slough 2, and the temperature of slough 2 is all lower than 150 DEG C, measure layer position 1 temperature and be greater than 200 DEG C, sensor 3 and measuring circuit 4 are electrically connected by cable or high-temperature electric cable 5.Measuring circuit 4 parts of instrument are transferred to the slough 2 of measuring under layer position by oil pipe according to different Jing Kuang, sensor 3 is put into measures layer position 1, and sensor 1 and measuring circuit are electrically connected by cable 5.Cable 5 length are greater than 1 meter.Because the temperature of slough is all lower than 150 DEG C, the temperature of measuring layer position is greater than 200 DEG C, sensor can be operated in easily and be greater than 200 DEG C of above high-temperature regions, measuring circuit is operated in 150 DEG C of following humidity provinces, by cable, the two is connected, well solve temperature high (being greater than 200 DEG C), there is no the problem of high-temp thermal recovery well instrument.
In order to make measuring circuit 4 not damage circuit in slough 2, measuring circuit 4 is arranged in sealed outer pipe, and measuring circuit 4 and cable 5 have sealing device.
Measuring circuit 4 has memory cell, and memory cell is connected with measuring circuit 4.After measurement completes, after measuring circuit 4 is fetched, instrument is connected with ground like this, just can analyzes by reading out data.
Worth attention be well-known components and common structure or the conventional means that the parts that do not describe in detail of the present embodiment and structure belong to the industry, not narration one by one here.
