Applicability Analysis and Optimization of Special Well in East Ilijik Thin Reservoir

East Iljik Gas field is located in the new development block of the western part of the project on the right bank of the Amu Darya River. The cap layer is a thick salt-paste layer, and the reservoir thickness is thin and the transverse development changes greatly. The conventional well type is difficult to achieve the development purpose, and special process wells should be considered to solve the problem of efficient and economic development of this kind of difficult-to-use reservoir. In this paper, combining with the characteristics of gas reservoir and gas field development present situation, the strata and reservoir properties, comprehensive considerationcomparative analysis of special process well increase yield of single well production, carry out four kinds of special process well well type suitability evaluation, studies have shown that, on the right bank of stepped horizontal well in the amu darya project in the western region has great application potential, can the efficient mining block gas reservoir potential, It provides a new technical idea for exploration and development, as well as a better choice for the optimal design of well trajectory, and has a broad application prospect in the western region of the right bank of the Amu Darya River project.
