Abstract
It is said that half of a geothermal power generation cost is a cost for geothermal well drilling. Therefore, the most important subject on promotion of geothermal utilization is how to reduce this cost. As for geothermal well drilling in Japan, it is effective to make an application of an MWD system which acquires information on a bottom hole rapidly and accurately for the reduction of the well drilling cost. This paper makes a research and a study of the present status of the MWD system and problems on geothermal well drilling and makes a technological study on the MWD system optimum to geothermal well drilling. The MWD system is clarified into the following three types in its application study: a simplified type, a semi-equipped type, a full-equipped type. Ranking of the three is conducted. As a result, the simplified type MWD is very high in the possibility of a wide spread, even under the present condition. The semi-equipped type MWD is considered to be popular if technical and economic advantages of the system are proven through the spread of the simplified type MWD. The fully-equipped type MWD is rather high in a service cost and resultantly is low in
