Field test of particle impact drilling (PID) technology was firstly carried out in deep well and hard formation in Sichuan province china on Oct. 2013. The test formation was named Xu Jiahe, which was very difficult to penetration. Field test result shows that the ROP (rate of penetration) was nearly doubled by this technology. It indicates that there is a profound application prospect of particle impact drilling, especially for hard rock formation. In this paper, the equipment and working principle was analyzed. The experiment and simulation results showed that the rock breaking efficiency was highly increased by this technology. The details of this field test were presented too in this paper that proved the sound effect of PID.

AbstractThis study aims to develop a basic kinesthetic based motion activity model for children aged 4-6 years. The design of this study refers to the Borg and Gall development model consisting of ten steps. These steps are 1) preliminary study aims to know the needs analysis in developing physical activity. It was concluded that a basic kinesthetic based motion activity model is required for children aged 4-6 years, 2) planning by formulating forms of participation in research); 3) design development, done by drafting and validated to 4 (four) experts and 1 (one) practitioner with 52 basic motion based kinesthetic activities, 4) conducting limited field test using 20 subjects, 5) revision of field test result limited clarity of implementation procedure and handbook, 6) broader field test using 50 subjects, 7) the revision of the field test results is broader, nothing needs to be revised because all aspects already meet the standards, 8) the main test through the model effectiveness test done 40 subjects, 9) the final product, 10) dissemination. Subjects in this study were children aged 4-6 years in Kindergarten. Place of research conducted in Tangerang City. Data were collected through documentation, observation, questionnaires and kinesthetic tests. Data analysis is done descriptively from qualitative and quantitative data. The results of the study are the basic kinesthetic based motion activity activity for children aged 4-6 years. The results prove that the development of a kinesthetic based motion activity model for children aged 4-6 years has been declared valid by motor learning experts, physical activity experts and early childhood education practitioners.Keywords: basic motion activity, kinesthetic, children aged 4-6 years.

The research aims at developing a guidebook for designing interactive distance learning for lecturers, considering that lecturers need guidance on how to design a learning implementation process that remains interactive in a full online learning system during the Covid 19 pandemic. The development of a guidebook stage adopted the model of Dick & Carey which modified into 4 stages, namely stages; (1) requirement analysis; (2) product design; (3) validation and evaluation; and (4) product revision. Based on development result, data found as follows; (1) the expert's assessment shows that the guidebook is included in the criteria of "very good" from the media aspect (94.44%) and "good" from the material aspect (86.11%) hence the guidebook can be used in learning; (2) test results on a small group shows that the product developed include in the criteria of  “good” (83,33%) hence the guidebook can be used in learning; (3) field test result that the product developed include in the criteria of “good” (89,28%) hence the guidebook can be used in learning. Key words: Interactive learning, distance learning

The calculation of fluctuating pressure is necessary during the progress of trip in the managed pressure drilling, because the bottomhole pressure should be constant during the progress of trip. The prediction model of the fluctuating pressure during the progress of trip was established based on the unsteady flowing theory. The actual application state of the prediction model was presented through a computational example. By the comparison between the computational result and the field test result, the computational result matches the field test result very well, which indicates the rationality and the accuracy of the model.
