The Geology Feature Of Tong Nanba Aera And The Complete Climb Majorization Study Desgin

Tectonic of Tong Nanba is located in northeast part of northeast folded zone in Sichuan. It is a large scale anticline. According to initial estimate, it contains almost 5501 natural gas and has good prospect. Due to the exploration here just beginning and few works about well competition have been carried out in this area, we have not form a set of technique of well competition majorization design, it brings in some difficult for well competition design and restricts the progress of exploration and development in this area.Through summing up the geology feature of this area, the author analyses the main aim of exploration about strata, structure, reservoir of T₁f³ and T₁²ã€‚ By this analysis, we think high temperature and pressure, erode gas that contain H₂S are the main characters of aim strata.Through analysis about exploration actuality, we bring forward the rules on well completion test and each application. These rules are adapt to the requirement of current exploration and development. At the same time, by analysis of well completion sensitivity and wide research contrast study, we establish the most suitable tubular chapiter size, and initially select anti-erode material, particularly screw thread, packer and correlative toolsAccording to multiple calculation, adjusting to the strength of well completion. It contains resist draught, resist inner pressure, resist outside pressure and three triaxial stress analysis。 It also initially analysis the deform of well completion and bring forward the importance of its flex. And we also choose Heba-1 well that has industrial product to adjust intensity tubular chapiter and to analysis deformation simulationThrough summing up the each unit of well completion, the author bring out the majorization design and procedure. of well completion. It set a good guarantee forlater exploration work in this area.
