Abstract:

In-situ developing technology is an important technology developing direction of oil shale production. Through study on the in-situ oil shale developing method oversea,a new technology was brought forward in order to solve the problem such as conventional heat conduction with low heat efficient and high cost for oil shale.The core technology of new method is style of heating the oil shale by using microwave. The microwave heating method belongs to the inner heating method, and electro-magnetic energy can do work directly to kerogen molecule of oil shale and change into heat energy to heat the inner and outer molecules simultaneously without heat conduction. In the implement of the microwave heating scheme, the multilateral horizontal wells were drilled and filled with wave materials to enhance the adsorption capacity of wave in oil shale. By using this scheme, shale oil in formation could be heated at high speed and more kerogen molecules would be changed into oil and gas. Shale oil could flow into wells from fractures formed during heating procedure and produced from formation.

Key words: oil shale, in-situ oil shale developing method, microwave heating developing technology, electro-magnetic energy, heat energy, kerogen cracking
