There are 10 wells located in the Shun 9 well field in Silurian system of Shuntuoguole block, 7 of them were drilled wells. The statistics of complex drilling accidents indicated that tight pull, sticking of drill tools, pump blocked and mud loss were major types of drilling accidents in building section of horizontal wells. Specially. The high drill resistance of the formation caused low penetration rate and frequently bits replacing. As a consequence, the exploration rate in this area was severely restrained. We proposed the following three technical research directions: anti-collapse technology research, long-reach horizontal well drilling technology research and countermeasures of enhancing drilling speed segment by segment along the well.

AbstractAs nanoscale science, engineering, and technology (NSET) becomes more integrated into precollege science curricula, it is crucial for teachers to develop coherent understandings of science principles (e.g., the structure of matter, size and scale, forces and interactions, and size-dependent properties) that allow them to coordinate these understandings from the macro- to the nanoscale. Furthermore, as teachers acquire new NSET content knowledge through professional learning opportunities, it is incumbent upon NSET educators to understand their developing content knowledge. To this end, we report results from a study in which we used a pre-/post-/delayed-posttest design to examine the change in 24 secondary (grades 7–12) science teachers’ NSET content knowledge as a result of their participation in a year-long professional development program that consisted of a 2-week intensive course and academic year follow-up activities. Participants showed significant gains from pretest to posttest and significant gains on the delayed test compared to the pretest. We also present trends that emerged in teachers’ open-ended responses that provided deeper insight into teachers’ NSET content knowledge. Finally, we discuss issues related to the assessment of teachers’ NSET content knowledge as well as the design of NSET professional development for teachers.

AbstractBy the end of the first decade of the 21st century, it was clear that nanotechnology was emerging as one of the most promising and rapidly expanding fields of research and development worldwide. It would not be long before scientists, science educators, engineers, and policy makers began advocating for nanoscience, engineering, and technology (NSET) related concepts to be introduced in K-12 classrooms. Indeed, there has been a surge in the development of pre-college NSET-related education programs over the last decade, as well as millions in funding to support the creation of these programs. In an effort to characterize the state of research to date on pre-college students’ and teachers’ learning of NSET content knowledge and related practices, we have conducted a systematic review of the peer-reviewed, published research studies to answer the following questions: What NSET content knowledge and practices in a pre-college context have been examined in empirical learning studies? What do these studies tell us about the NSET content knowledge and practices that pre-college students and teachers are learning? Implications and recommendations for future research are also discussed.
