Abstract

The invention provides a thermoplastic oil-resistant polyolefin elastomer sheath material and a preparation method thereof. The material is mainly prepared from, by weight, 70-80 parts of polypropylene resin, 20-30 parts of dynamic vulcanized thermoplastic rubber, 0.5 part of antioxidant, 0.3 part of anti-copper agent and 0.1 part of rheological agent. The preparation method includes the steps that the raw materials are metered by weight and put into a mixer to be evenly mixed, then the mixture is conveyed into a dual-screw extruder for blending extrusion, filtering and drawing, the mixture is cooled through a water tank and dried and then enters a granulator to be cut into particles, the particles are packaged, and finished products are obtained. The sheath material is low in density, good in heat resistance and oil resistance, and capable of serving as a hydraulic packaged cable sheath material for well logging; the preparation method is reasonable in deign and easy to operate.

Description

technical field [0001] The invention relates to a hydraulic sealing cable sheath material for well logging and a production method thereof, in particular to a thermoplastic oil-resistant polyolefin elastomer sheath material and a preparation method thereof. Background technique [0002] Since the 1980s, with the rapid development of my country's national economy, the petroleum industry has become a pillar industry in my country, and the world economy is increasingly dependent on the petroleum industry. Oil and gas detection and oil extraction technologies continue to develop, oil field detection and electric submersible pump oil extraction technologies are widely used in the petroleum industry. As one of the essential technologies for oil and gas exploration and oil recovery, hydraulically encapsulated cables for oil field logging are widely used, and its technology has been monopolized by foreign companies. [0003] The technical difficulties of thermoplastic oil-resistant...
