Abstract
A kind of charge bearing detecting cable conductor blocking cream, belongs to charge bearing detecting cable field, and composition agent by weight of the invention is allocated as follows：High temperature resistant silicone grease：60%, Nano graphite powder：20%, high temperature resistant silicone oil：20%, the usefulness of the invention is：The generation of the gas-blowing phenomenon in space between HTHP lower conductor and insulating barrier and between the stranded conductor of stranded conductor can be effectively prevented, the orderly progress of well logging is ensured.
Description
Technical field
The present invention relates to a kind of charge bearing detecting cable conductor blocking cream, hp-ht well is specifically applied to holding lotus
The closure in the space between the closure between cable conductor and insulating barrier and the stranded conductor of stranded conductor is detected, belongs to and holds lotus
Detect field of cables.
Background technology
The charge bearing detecting cable of existing conventional structure, cross sectional shape is circle, and ecto-entad order is described：By armor layer,
Insulating barrier, multicore copper conductor are constituted.Because conductor layer is formed using many copper cash are stranded, therefore between conductor and insulation and many
The gap formed between stock copper conductor.At relatively low temperatures and pressures conductor and insulation between closure and multiply copper conductor
Between be not in gas-blowing phenomenon, statistics display is higher than 150 DEG C when temperature, and pressure is easy for occurring gas blowby and showed when being more than 60MPa
As, or even cause cable to destroy, well logging failure.By market survey, not yet find relatively good to prevent gas-blowing phenomenon from sending out at present
Raw good solution.
The content of the invention
For above-mentioned deficiency, the invention provides a kind of charge bearing detecting cable conductor blocking cream.
The present invention is achieved by the following technical solutions：A kind of charge bearing detecting cable conductor blocking cream, group of the invention
It is allocated as follows into agent by weight：
High temperature resistant silicone grease：60%, Nano graphite powder：20%, high temperature resistant silicone oil：20%.
The usefulness of the invention is：Can effectively it prevent between HTHP lower conductor and insulating barrier and stranded conductor
Stranded conductor between space gas-blowing phenomenon generation, ensure well logging orderly progress.
Brief description of the drawings
Fig. 1 is single core load detecting cable structural representation, and Fig. 2 is multicore charge bearing detecting cable structural representation.
In figure：1st, external armor layer, 2, internal armored layer, 3, insulating barrier, 4, conductor blocking layer, 5, stranded conductor.
