Oilfield production technology plays an important role in oilfield development, so it is necessary to sumarize continuously the characteristics and requirements in the development and to propose the key issues to be tackled, by which the production technology can be improved and the level of oilfield development can be raised.

Bioremediation is an optimal option for treating Exploration and Production (E&P) wastes and oil-contaminated soil, which is characteristic of high efficiency, low cost and less environmental contamination.

This paper utilizes the illustrations of oil drilling-production equipments development laws to conclude ten items of thinking of blazing new ideas and crative methods.

The initial discussion of development directions of offshore oil drilling and production equipment in China;

The paper minutely introduces the working mechanism ,the structure compo sition, the techical parameters,the characters,the mining process and the safety measures of CLZ150B surface highwall drill-miner, and the general condition of its growing at home and abroad are concerned so that we can understand and recog nize the new member of surface miner briefl
